ST. PETERSBURG, Fla. - Cole Irvin is starting for the Orioles tonight on normal rest, the only certainty in the rotation for the four-game series against the Rays at Tropicana Field.

Irvin has allowed two runs in 11 1/3 innings since returning to the rotation, and he’s carrying a 2.61 ERA and 1.142 WHIP in nine starts. He faced the Rays on Sunday at Camden Yards and allowed two runs in 6 1/3 innings. José Caballero led off the seventh with a homer.

Irvin has a 3.86 ERA and 1.169 WHIP in five career games (four starts) against the Rays. He’s surrendered six runs and 14 hits in 13 1/3 innings at Tropicana Field.

The starters for the next three games remain TBA.

Jordan Westburg is starting at second base and Ramón Urías is at third. Connor Norby goes to the bench.

The mailbag won’t enter Canada unless it’s the postseason, but Florida is fine.

The Orioles begin another four-game series tonight at Tropicana Field and hope to do better than a split. The bar is raised. It wasn’t that long ago that winning twice against the Blue Jays would have been cause for celebration.

Let’s get to the latest sequel to the beloved 2008 original, which is always worth celebrating. You know the rules. You send ‘em and I answer ‘em, with little to no editing.

Your level of clarity won’t ruin the hilarity. Your particular style won’t get me riled.

Also, my mailbag is at home beneath the dome and yours is allergic to fake grass.

Cade Povich makes his major league debut this afternoon in Toronto to close out the four-game series. His contract was selected from Triple-A Norfolk, and the Orioles optioned reliever Nick Vespi to make room on the active roster.

The 40-man roster is full.

Povich is wearing No. 37.

Jordan Westburg is leading off, with Gunnar Henderson sliding down to fourth. Connor Norby starts at second base for the third time in four games.

Austin Hays is in left field and Colton Cowser is in center.

The next Orioles prospect to debut in the majors is a pitcher, left-hander Cade Povich, who joined the team yesterday in Toronto and hailed the taxi squad.

Manager Brandon Hyde told the media after last night's walk-off loss that Povich would start this afternoon's series finale against the Blue Jays. He can occupy the last spot on the 40-man roster, but a reliever must be removed from the active roster unless something is wrong with Kyle Bradish that we still don't know about.

The only information shared is that he's pushed back and it could be more than one day. And that TBA is gonna be a common listing among the probables.

The next position player to debut might be third baseman Coby Mayo, but he’s on Triple-A Norfolk’s injured list with a fractured rib. The good news is he’s swinging a bat.

Jackson Holliday already got his first major league hit, a single, before the Orioles optioned him. Connor Norby became the 12^th Orioles player to homer for his first hit, delivering a two-run shot to left field Tuesday night at Rogers Centre.

Jordan Westburg is starting at second base tonight and Connor Norby is out of the lineup after homering last night for his first major league hit.

Norby is the 12^th player in club history whose first hit is a home run.

Ramón Urías is playing third base. Kyle Stowers is in left field, Cedric Mullins is in center and Ryan O’Hearn is in right.

Anthony Santander is the designated hitter.

Ryan Mountcastle homered twice last night and is 29-for-91 (.319) with seven doubles, eight home runs, 26 RBIs and a 1.044 OPS in 24 career games at Rogers Centre.

The Orioles haven’t confirmed their starter for Thursday afternoon’s series finale against the Blue Jays. However, one of their top prospects is in the running.

He won’t be far from them.

Left-hander Cade Povich is headed to Toronto and will be placed on the taxi squad later today, according to a source, perhaps setting up his major league debut.

Povich was scheduled to start for Triple-A Norfolk on Thursday at Scranton/Wilkes-Barre. Now he’s an option for the Orioles, who are undecided about Kyle Bradish’s status.

Bradish would be working on his normal turn Thursday, but manager Brandon Hyde told the assembled media yesterday that the club might push him back. If so, Bradish would open the four-game series against the Rays on Friday night in St. Petersburg, Fla. or pitch the following day.

The Orioles are halfway through their series in Toronto and the roster underwent a few changes since the conclusion of the last homestand.

Tweaking the bullpen was expected. The question was which reliever would be recalled and which would be optioned or designated for assignment. Something had to be done to inject a fresher arm.

A freak accident on the on-deck circle forced the other move.

Here are three questions, raised like fingerprints after Monday’s announcements.

How long will Connor Norby stay with the Orioles?

Connor Norby stays at second base tonight and moves up to eighth in the order as the Orioles try to guarantee at least a split of their four-game series in Toronto.

James McCann is catching and batting ninth.

Colton Cowser remains in center field, putting Cedric Mullins on the bench. Austin Hays stays in left field.

Hays hit his first two home runs last night since Sept. 19.

Adley Rutschman is the designated hitter. Ryan O’Hearn moves to the bench.

Running low on starting pitching, the Orioles are bringing back a veteran who didn’t make the team out of spring training.

The club is on the verge of signing Julio Teheran to another minor league deal, according to a source. The sides are "close."

Teheran, 33, agreed to a minor league deal on Feb. 28 that would have paid $2 million if he pitched in the majors. He allowed five runs and nine hits with seven walks and 10 strikeouts in 13 1/3 innings and was granted his release.

The Mets signed Teheran on April 5 and he became a free agent again six days later after making one start and allowing four runs and six hits in 2 2/3 innings in Atlanta.

The Cubs signed Teheran on April 18 and released him Saturday after another opt-out. He posted an 8.82 ERA and 1.806 WHIP in eight starts with Triple-A Iowa.

Anthony Santander saw the board and an opportunity.

But who would play?

Chess ranks among Santander’s favorite hobbies and the Orioles’ clubhouse is equipped to satisfy it. However, he’s more likely to find teammates gathering at the pool or bumper pool tables. They weren’t inclined to take his cue, as it were, and trade in the rack for a rook.

The next move was to choose a partner.

Jorge Mateo has the most speed on the club and he’s also a fast study. He was introduced to the game a year ago and already developed the same passion for it as Santander.

The Orioles begin their four-game series in Toronto tonight with Connor Norby making his major league debut. Norby is playing second base and batting ninth.

Norby had his contract selected from Triple-A Norfolk earlier today. Second base won’t be occupied by Jorge Mateo until he’s reinstated from the seven-day concussion list.

Austin Hays is in left field, Colton Cowser is in center and Anthony Santander is in right. Ryan O’Hearn is the designated hitter.

Gunnar Henderson, in his usual leadoff role, is the third-youngest Orioles player to hit more than 50 home runs in his career behind Eddie Murray and Boog Powell.

The Orioles’ 6-1 record against the Blue Jays last season tied for their best in the series. They also won six of seven games in 1982.

The Orioles could make multiple roster moves today before beginning their four-game series against the Blue Jays.

A source confirmed that second baseman Connor Norby and left-hander Nick Vespi are joining the club in Toronto. They boarded the same flight out of D.C. as three beat writers who first laid eyes on them.

The 40-man roster has an opening for Norby if the Orioles select his contract from Triple-A Norfolk, and they can create two more spots later by transferring pitchers John Means and Tyler Wells to the 60-day injured list.

Norby has appeared in 51 games, missing a week with a left wrist injury, and is batting .286/.374/.510 with 17 doubles, a triple, nine home runs and 36 RBIs in 238 plate appearances. He’s made 18 starts in left field and 15 in right, as well as 12 at second base.

The Orioles selected Norby in the second round of the 2021 draft out of East Carolina. He'd give the Orioles a right-handed bat and some versatility, the movement necessary with Jackson Holliday making most of the starts at second base.

The May 8 game in D.C. seems so long ago. Worlds away for the closer with the fifth-most saves in baseball history.

Craig Kimbrel didn’t make it out of the ninth inning again for the fourth time in five tries. He allowed two runs with a hit and a pair of walks, and his ERA swelled to 4.73.

Manager Brandon Hyde spoke with him about a reset, with his next three appearances coming in non-save situations but remaining high leverage due to the club’s propensity for playing close games. A clean seventh inning on May 10 against the Diamondbacks, a win earned the following day with a scoreless 11^th that included a hit batter, and a spotless seventh on May 13 against the Blue Jays.

Perhaps it’s sneaked up on a few people, but Kimbrel is in a dominant stretch with eight consecutive scoreless, hitless and walk-less outings, and he’s struck out 10. The last five have resulted in saves to push his season total to 13 and career mark to 430.

Opponents are hitless in 22 at-bats against him in these eight games.

Walking along Eutaw Street may require protective headgear. Anthony Santander launched a baseball over the flag court in right field yesterday and Gunnar Henderson splashed down this afternoon with his 19th home run and sixth leading off the first inning.

Zack Littell got a called strike with his sinker and regretted the slider that followed. Henderson pummeled it.

The Rays were taking a beating during their visit to Baltimore, but they became the aggressors in the eighth and finally broke a bullpen that amassed 12 1/3 scoreless innings in a row before today.

Dillon Tate returned after recording the last two outs in the seventh and surrendered back-to-back singles and Jose Siri’s two-run, go-ahead double, and the Orioles lost 4-3 before an announced crowd of 32,463 at Camden Yards.

The Orioles were unsuccessful in their bid for a fifth series sweep of at least three games and are 37-20 as they head to Toronto.

Austin Hays is in left field this afternoon as the Orioles close out the series against the Rays and their homestand.

Cedric Mullins is in center and Anthony Santander is in right. Just like the old days.

Jordan Westburg is the third baseman and Adley Rutschman is serving as the designated hitter.

Colton Cowser has posted a 1.009 OPS when batting seventh and a .676 OPS anywhere else in the lineup. He’s out of today’s lineup.

Ryan Mountcastle’s hot bat stays. He’s slashing .459/.500/.757 (17-for-37) with five doubles, two home runs, six RBIs, three walks and eight runs scored in the last 10 games since May 21.

The task at hand can’t change because of an elbow.

Teammates, manager Brandon Hyde and his staff collectively hurt for John Means and Tyler Wells, who will undergo surgery to repair their ulnar collateral ligaments. Two huge contributors to the club are gone, but the process stays the same.

Go out and do your job. Stay within yourself. Don’t feel pressure to replace the missing and make it worse.

“I just want them to do what they do,” manager Brandon Hyde said yesterday afternoon. “Give us the best starts that they can. I don’t want them to try to do anything extra. We’ve thrown the ball really well so far this year. Hopefully, we continue to do that.

“I want our guys to do what Albert Suárez did (Friday) night. Just give us as much as they can every time out.”

The second batter that Kyle Bradish faced today singled into right field, the ball glancing off Jorge Mateo’s glove as he attempted to make a sliding stop. A cleaner single followed. The no-hit stuff and the breaks were left back in Chicago.

Bradish lasted only 2 2/3 innings after losing his command and issuing three consecutive walks, the last with the bases loaded that broke a 4-4 tie. But a game was won again.

Hitting four home runs and getting strong work out of the bullpen made it happen. This is a team that will find a way.

Ryan Mountcastle cleared the center field fence twice within the first four innings, going back-to-back with Anthony Santander in the first, Jacob Webb came to the rescue with 2 1/3 scoreless, and the Orioles claimed another series against a division opponent with a 9-5 victory over the Rays before an announced crowd of 36,958 at Camden Yards.

Jordan Westburg marked his return to the lineup by homering in the second inning, and the Orioles moved a season-high 18 games above .500 at 37-19. They’re 14-0-5 in their last 19 series against the American League East and go for the sweep Sunday before flying to Toronto.

Jordan Westburg returns to the Orioles’ lineup today after missing the past two games with a sore right hand.

Austin Hays and Cedric Mullins are on the bench, with Kyle Stowers in left field and Colton Cowser in center. Ryan O’Hearn is the designated hitter.

Anthony Santander, who’s in right field, has posted a .333 average and .762 slugging percentage in plate appearances ending on the first pitch, according to STATS.

Kyle Bradish is back on the mound after his seven hitless innings in Chicago. He brings a 1.75 ERA and 1.052 WHIP in five starts and hasn’t surrendered a home run.

Bradish is 1-3 with a 6.18 ERA and 1.410 WHIP in five career starts against the Rays. Yandy Díaz is 6-for-14 with a double, Randy Arozarena is 4-for-14 with a triple and two home runs, and Harold Ramírez is 5-for-13 with a double.

Albert Suárez made another start with the Orioles last night. Cole Irvin closes out the Rays series on Sunday and is unlikely to do more bouncing between rotation and bullpen.

A minimum of five starters are needed on a major league staff. The Orioles want to expand it to six but injuries have created an unsettled situation.

Dean Kremer’s right triceps injury is improving but he might go on a brief rehab assignment. John Means and Tyler Wells are undergoing elbow surgeries within the next few days and won’t pitch again in 2024, crushing blows for them and the team.

A six-man rotation? The Orioles have fingers crossed that they can keep their quintet from crumbling.

A knee-jerk response to torn elbow ligaments is to burn up the phone lines and make a trade. The Orioles don’t have immediate plans to do it, though executive vice president/general manager Mike Elias said he’s “in contact” with other teams.

The season shifted past the one-third mark for the Orioles tonight. It also dumped them into a treacherous stretch of 29 games in 30 days, the only breather coming on June 17, wedged between series against the Phillies and Yankees. The two teams with the best records in baseball.

How they responded tonight again illustrated why they also belong among the finest.

They pitched, they made plays in the field and they eventually hit in the clutch. Another division opponent was on the wrong side of it.

Austin Hays came off the bench to deliver a game-tying single in the sixth inning, Jorge Mateo doubled to score two more runs, and the Orioles defeated the Rays 3-1 before an announced crowd of 27,364 at Camden Yards.

Craig Kimbrel recorded his 13^th save and 430^th of his career to take sole possession of fifth place on the all-time list, and the Orioles improved to 36-19 after winning for the seventh time in eight tries.
