The Austin Hays workouts are turning into an injury rehab assignment.

The Orioles announced that Hays will begin playing for Double-A Bowie on Tuesday night against the Akron RubberDucks at Prince George’s Stadium. First pitch is 6:35 p.m.

Hays is on the injured list since April 22 with a left calf strain. He was 5-for-45 with no extra-base hits and a .311 OPS in 19 games.

The recent at-bats were producing more solid contact and he collected a hit in each of his last two games. He tweaked the knee running from first to third base against the Royals on April 20 in Kansas City and decided he couldn’t cover the necessary ground in left field, which led to Colton Cowser as a defensive replacement and a trip to the IL.

Hays ramped up baseball activities Thursday at Camden Yards, sprinting between bases and taking batting practice on the field.

In the unpredictable world of baseball, it’s been fascinating to watch Jorge Mateo go from bubble non-tender guy to trade bait to integral part of the Orioles’ lineup planning.

He has a role on a first-place team and owners of the best record in the American League that for quite some time appeared to have little use for him. Another good reminder of the dangers of rushing to conclusions.

Mateo was groomed and advertised as more of a super-utility guy, with club promises to test him more regularly in the outfield at spring training. It didn’t happen that much, and he’s settled in as a second baseman.

Jackson Holliday eventually will become the everyday player at the position, but he was platooned during his brief stay in the majors and currently is leading off again for Triple-A Norfolk. He went 1-for-3 yesterday with a double, two walks, two strikeouts and a run scored and is batting .278 with a .928 OPS.

Mateo entered yesterday’s series finale against the Reds with home runs in two of his last three games. Before Thursday, he hadn’t hit a ball over the fence since April 30, 2023 in Detroit. He delivered an inside-the-park homer on Aug. 20 in Oakland.

The Orioles are trying for the sweep this afternoon in Cincinnati and Dean Kremer is hoping to keep the pitching staff on its roll.

The team ERA is 1.17 in the last six games and 2.23 in 13. John Means notched the rotation’s seventh scoreless start last night.

The Reds have scored one run in the first two games of the series, and it came against Craig Kimbrel last night in the ninth inning before Yennier Cano recorded the two-out save.

Kremer has registered a 4.19 ERA and 1.078 WHIP in six outings. His eight home runs surrendered are tied for most in the American League.

Kremer tied his season high with seven innings in his last start against the Yankees, with both runs scoring on solo homers. He faced the Reds in 2022 in Cincinnati and allowed six runs and 10 hits in 4 1/3 innings.  

The Orioles wrap up their series against the Reds this afternoon, going for the sweep, and I’m unwrapping three more questions that hang in the air. At least where I’m breathing.

The good news is there’s a definite answer to the first one.

What the heck happened to Terrin Vavra?

Vavra posted photos recently on his Instagram account with a caption about “the most trying 10 months of my career” and offering thanks for the support he’s received. The first photo showed Vavra in his hospital bed holding one of his children.

Was this a new surgery on his shoulder that would perhaps ruin his chances of playing in 2024, or was he celebrating the end of his rehab from his original labrum procedure last fall?

John Means makes his 2024 debut tonight as the Orioles continue their series in Cincinnati following last night’s 3-0 win. And after Cole Irvin ran his scoreless streak to 20 2/3 innings.

Means hasn’t pitched for the Orioles since Sept. 29 against the Red Sox, when he allowed two runs and three hits in 6 1/3 innings. He faced teammates in a simulated game at Camden Yards prior to the Division Series and experienced discomfort in his elbow/forearm area that led to his exclusion from the roster, a delayed off-season throwing program and stint on the injured list.

Tonight marks his latest comeback to the rotation, and he’s with a club that’s 21-11, has won 13 of its last 18 games and is one ahead of the Yankees for first place.

The Reds are a new opponent for Means, who’s posted a career 3.97 ERA in 13 starts against the National League.

Jeimer Candelario is 3-for-8 with a double, triple, RBI and walk against him. Santiago Espinal is 2-for-2 with a double and RBI.

The Orioles were forced to wait last night until the rain finally stopped to begin their three-game series in Cincinnati.

The delay also gave the organization time to catch its breath after the barrage of news and updates that hit the media.

To review:

Gunnar Henderson and Colton Cowser are monthly award winners.

I participated in the voting and won’t reveal my ballot, but Henderson and Royals catcher Salvador Perez had really strong cases as I recall. Yeah, really strong.

Heston Kjerstad, who was named the International League’s Player of the Month earlier today, is starting in left field tonight for the series opener against the Reds in Cincinnati.

Colton Cowser is on the bench, whether to rest or to heal from slamming his knee into the outfield wall yesterday and being hit on the foot by a pitch. Either way, he's one of the reserves.

Jorge Mateo gets another start at second base after homering yesterday. Ryan O’Hearn is the designated hitter.

Cole Irvin hasn’t allowed a run in his last 14 1/3 innings. He stays in the rotation despite Kyle Bradish and John Means leaving the injured list.

Irvin has made three career appearances against the Reds, including one start, and allowed one run in 5 1/3 innings.

The Orioles won three of four games from the Yankees, they lead the division, and they just claimed two monthly awards.

This is a team on a roll.

Shortstop Gunnar Henderson was named the American League’s Player of the Month and outfielder Colton Cowser was chosen Rookie of the Month.

Henderson batted .291 (34-for-117) with three doubles, three triples, 10 home runs, 24 RBIs, eight walks, 25 runs scored, six stolen bases and a .624 slugging percentage in 29 games. He’s tied for the major league lead in homers and ranks first in the AL in slugging and total bases. He’s tied for second in triples, extra-base hits and runs scored.

The 10 homers make Henderson the youngest player in history to reach that total before May 1.

Austin Hays grabbed his spikes yesterday and walked out of the Orioles’ clubhouse. He had another box to check.

Hays ran the bases for the first time since landing on the 10-day injured list on April 22 with a strained left calf muscle. He sprinted from third to home and wasn’t favoring the leg.

That was only part of his workout. The Orioles didn’t schedule batting practice but they arranged for Hays to take some swings on the field.

It was significant ramping of baseball activities after Hays had run the last two days, hit in the indoor cage and threw.

“Everything’s been going good,” he said. “I’ve been up to 90 percent of my game speed, so getting really close. Just got to check a couple more boxes, but everything we’ve done so far, there have been no setbacks, nothing negative. I think we’re getting really close.”

The Orioles set their rotation for the series against the Reds in Cincinnati. Albert Suárez isn’t in it.

Cole Irvin starts Friday night and John Means makes his 2024 debut the following night. Dean Kremer gets the ball Sunday afternoon.

Suárez moves to the bullpen. He’s listed today among the relievers after posting a 2.35 ERA in three starts.

“It’s up for grabs right now, so kind of a wait and see,” said manager Brandon Hyde said of Suárez’s role. “I’m interested to see what it looks like in different ways. But he’s also a starter candidate for us if we maybe go with a six-man down the road. All different types of roles. So right now he’s kind of a wild card for us in our bullpen.”

Kyle Bradish is starting this afternoon after his reinstatement from the 15-day injured list. There’s a sense of relief in the organization following his January diagnosis of a sprained ulnar collateral ligament.

Ryan McKenna gets the start in center field this afternoon with the Yankees starting left-hander Carlos Rodón.

Adley Rutschman is the designated hitter for the Orioles and James McCann is behind the plate.

Anthony Santander is starting in right field after beginning last night’s game on the bench. Jorge Mateo is the second baseman, with Jordan Westburg at third.

Colton Cowser stays in left field.

For the Orioles

Kyle Bradish is ready to make his 2024 debut.

The Oriole reinstated Bradish from the 15-day injured list this morning and he’s starting against the Yankees in the series finale at Camden Yards. Bradish was diagnosed with a sprained ulnar collateral ligament in his right elbow in January, received a platelet-rich plasma injection and worked his way back into the rotation.

Bradish’s injury rehab assignment could have run until mid-May, but the Orioles deemed him ready after one start with Double-A Bowie and two with Triple-A Norfolk.

Yohan Ramírez was designated for assignment after retiring the side in order last night in the ninth inning. He had a 6.00 ERA and 0.833 WHIP in five outings.

The 40-man roster is down to 39 players.

Heston Kjerstad sat at his locker yesterday, slumped in his chair and looking at his phone. He smiled when a visitor approached and asked for a few minutes.

He did the same thing the previous day. Being in or out of the Orioles lineup doesn’t influence his mood.

Kjerstad was making his second start since the Orioles recalled him on April 23. He played right field that night in Anaheim and went 0-for-4 with three strikeouts, and he grounded out as a pinch-hitter for Ramón Urías in the 10th inning on April 26 against Athletics fireballing closer Mason Miller.

The organization’s No. 4 prospect, ranked 29^th in baseball by MLB Pipeline, mostly has just sat. At his locker and on the bench. And without a word of complaint.

“It’s where the game works right now with the lineup,” he said. “I’m just doing the best with my preparation. Stay ready, whether it’s a pinch-hit late in the game or whatever they need from me. Just staying ready with my cage work and everything.

The clarity that must come to the Orioles’ rotation plans weren’t evident this afternoon.

Manager Brandon Hyde confirmed the obvious intention of starting John Means, who was reinstated today from the 15-day injured list. However, he isn’t ready to announce who’s on the mound Thursday afternoon or this weekend in Cincinnati.

“We have some roster moves we’ll have to make for a couple guys,” Hyde said.

The pitching waters became murkier with Grayson Rodriguez going on the 15-day injured list with right shoulder inflammation. His next turn on regular rest would have come Saturday night.

Hyde said he didn’t know the severity of the injury but was staying optimistic.

Heston Kjerstad is starting in right field and batting eighth tonight, his second time in the lineup since the Orioles recalled him.

Colton Cowser moves up to fifth. Ramón Urías is starting at third base.

Ryan O’Hearn is the designated hitter. Anthony Santander begins the game on the bench.

Santander’s nine doubles are tied for first in the American League, but he’s batting .213/.289/.426 in 28 games.

Adley Rutschman will try to extend his hitting streak to 12 games. He’s batting .388/.400/.592 (19-for-49) with one double, three home runs, 11 RBIs, a walk and five runs scored during his streak.

The Orioles reinstated John Means from the 15-day injured list this afternoon. How they made room for him wasn’t among the speculated moves.

Grayson Rodriguez was placed on the 15-day IL with right shoulder inflammation, retroactive to yesterday.

Rodriguez rebounded Monday from a rough start by shutting out the Yankees over 5 2/3 innings. He threw 101 pitches to tie his career high and navigated through some clutter with five hits and three walks.

He didn’t exhibit any signs of injury and was much sharper than his outing in Anaheim, when he allowed seven runs and 11 hits in 4 1/3 innings.

For the season, Rodriguez is 4-1 with a 3.71 ERA and 1.412 WHIP in six starts and has struck out 37 batters in 34 innings.

The Orioles haven’t announced their starter for Thursday afternoon, when they close out their series against the Yankees and the latest homestand. The spot remains TBA, with an assumption attached that Kyle Bradish is making his 2024 debut.

Bradish would be working on an extra days’ rest after starting Friday with Triple-A Norfolk. Cole Irvin would be taking his normal turn if he’s the choice.

The Orioles head to Cincinnati for a weekend series. Irvin has made three career appearances against the Reds, including one start, and allowed only one run in 5 1/3 innings. But stats in small samples aren’t swaying the Orioles one way or the other.

The number that really matters is six – an extra starter in a five-man rotation.

John Means will make it seven later this week.

One of the biggest potential influencers in tonight’s game was doing important work on the field before batting practice. Craig Kimbrel stretched while holding a weighted ball, played catch and walked to the bullpen for a lengthy session. The Orioles needed proof that the tightness was gone in his upper back and he could be a consideration in a save situation.

On Wednesday, as it turned out.

Manager Brandon Hyde was giving Kimbrel another game to recover after the veteran closer was removed Sunday in the ninth inning, his third appearance in five days. But don’t tell the Yankees your plans. Let them think he’s ready.

Let him appear to demonstrate that he could take the ball in the ninth and see how the game played out.

Don’t worry about putting the cart before the horse. Figure it out before knowing whether a lead would require protecting.

Craig Kimbrel is feeling much better after leaving Sunday’s game against Oakland with tightness in his upper back. However, his availability for tonight remains in question.

Manager Brandon Hyde couldn’t provide much of an update during his media session.

“Not really sure,” Hyde said. “He’s going through some treatment stuff right now and then I’m going to talk to him here in a little bit. But as of right now at 3:42, I’m not really sure.”

Kimbrel did some stretching exercises on the field, played catch and had an extensive bullpen session. He appeared to be throwing with maximum effort.

Hyde is going with a closer by committee during Kimbrel’s absence, with Danny Coulombe getting the last three outs last night for his third career save.

Jorge Mateo gets the start at second base tonight for the Orioles and James McCann is behind the plate.

Heston Kjerstad stays on the bench against a left-hander, former Orioles Rule 5 pick Nestor Cortes. He’s been in the lineup once since the Orioles recalled him last Tuesday.

Colton Cowser is in left field and batting ninth. Jordan Westburg is the third baseman.

Dean Kremer is making his sixth start. He’s posted a 4.61 ERA and 1.061 WHIP in 27 1/3 innings.

Kremer struck out 10 batters over 5 1/3 innings in his last start in Anaheim. He has a 5.04 ERA and 1.410 WHIP in nine career starts against the Yankees.
