Orioles manager Buck Showalter was left to explain another disappointing outing from Jake Arrieta and his club's failure to take advantage of some late opportunities in a 6-5 loss to the Red Sox before 27,806 at Camden Yards. Arrieta was charged with four runs and eight hits in 5 2/3 innings. "He's a pitch away from getting out of there with three runs in six innings," Showalter said. "He was so deep in the count. He had a lot of counts in his favor and couldn't put people away. I...

BOWIE, Md. - Hello from Prince George's Stadium, where the Bowie Baysox host the Richmond Flying Squirrels tonight in Eastern League baseball at 7:05 p.m. It is here where the Orioles' Brian Roberts will begin his 20-day minor league rehab assignment, playing in a game for the first time since May 16, 2011. He has missed 166 games since that time, playing in just 98 games combined for the Orioles over the last two seasons. Roberts has only played in 27 career games at Bowie. He began the...

PHILADELPHIA - The Nationals have a two-game sweep over the Marlins, but have yet to register a three-game sweep this season. They've got yet another shot tonight. Ryan Zimmerman, who sat out last night with shoulder soreness, returns to the Nationals lineup, playing third base. Here are the lineups for tonight's game: For the Nationals: 2B Danny Espinosa RF Bryce Harper 3B Ryan Zimmerman 1B Adam LaRoche SS Ian Desmond CF Rick Ankiel LF Xavier Nady C Jesus Flores P Edwin Jackson For the...

Jake Arrieta's maddening inconsistency reared its ugly head again this afternoon. Arrieta was charged with four runs and eight hits in 5 1/3 innings, with three walks, two strikeouts and a home run. He threw 98 pitches, 58 for strikes. The fourth run scored on Kelly Shoppach's two-run homer off reliever Luis Ayala, only his second this season. Daniel Nava hit No. 2 off Arrieta earlier in the inning, after the first two batters were retired. Arrieta held the Nationals to one run over seven...

After much deliberation, the Orioles have decided to promote pitcher Dylan Bundy to Single-A Frederick, where he'll start Saturday night against Salem at Harry Grove Stadium. The original plan called for Bundy to make three five-inning starts with low Single-A Delmarva before moving up, but the Orioles have decided to accelerate his program. Bundy, the fourth overall pick in the 2011 First-Year Player Draft, tossed five more scoreless innings Sunday against Hagerstown, keeping his ERA at...

PHILADELPHIA - The Nationals will go for the sweep of the Phillies tonight when Edwin Jackson opposes Cole Hamels, but even before tonight's game, Washington has already locked up another series win, its 10th of the season. Of those 10 series wins, six have come on the road. How much better is this Nats team on the road than the 2011 version? Last season, the Nats didn't earn their sixth road series win until Sept. 12-14 when they swept the Mets. With last night's win, the Nats matched...

As opposed to your nightly one. We have a 12:35 p.m. start here. Xavier Avery reached on an infield hit to lead off the bottom of the first inning. Red Sox pitcher Daniel Bard fielded the ball on the right side of the mound and made an off-balance throw that skipped past first baseman Kevin Youkilis. He had no shot at the speedy rookie. Avery advanced to second on Robert Andino's single, tagged and took third on Nick Markakis' fly ball to left field, and tagged again and scored on Chris...

Orioles manager Buck Showalter confirmed this morning that left-hander Zach Britton will make his first injury-rehab start Saturday at Double-A Bowie. Britton will stay with the Baysox and pitch again May 31 at Akron. The Orioles could choose to keep Britton on his rehab assignment or activate him from the disabled list. That decision is pending. Let's see how he gets through those starts. Jason Hammel remains confident that he'll make Friday night's start against the Royals at Camden...

A win today would give the Orioles their fourth consecutive series win against the Red Sox. The last time the Orioles won four straight series against Boston was April 27-Aug. 21, 1960, when they won six in a row. The Orioles have already won three straight series against the Red Sox for the first time since Sept. 17, 1990-June 30, 1991. The Orioles are 21-1 when their rotation gives them a quality start. The only defeat came April 30 at New York, when Jason Hammel lost 2-1. Since July 29,...

The argument can be made that Tuesday night's 5-2 conquest of the division rival Philadelphia Phillies, solidified by a two-RBI triple off the bat of Bryce Harper, was one of the most enjoyable for Nationals fans so far this season. The Nationals have beaten the Phillies six straight time, the first time in a 43-year franchise history that the Expos/Nationals have done so. The same argument can be made for Washington's 9-3 win on Sunday versus the regional rival Baltimore Orioles in which...
