Nationals general manager Mike Rizzo decided to call up top prospect Anthony Rendon on Saturday night to replace Ryan Zimmerman, who was placed on the 15-day disabled list with a hamstring injury. Zimmerman attended batting practice and was stretching, but is not hitting yet. Manager Davey Johnson said Zimmerman is still a "couple days behind" Wilson Ramos in their recoveries from injuries, but is still on track to return when the 15 days expire. Rizzo said Rendon will "most likely"...

Given the way Adam LaRoche has been struggling at the plate lately, Davey Johnson knew LaRoche would be taking early batting practice today to try and find a groove. Johnson was curious how LaRoche's cage session would go, so he popped out to the field this afternoon to watch his first baseman take some cuts. Only problem was, LaRoche wasn't in the group rotating into the cage. The Nationals had so many players getting in early BP that LaRoche, mired in an 0-for-11 slump with eight...

It has not been the fastest start for Potomac Nationals first baseman Kevin Keyes. But Wednesday's home run at Carolina may change that. His first home run of the season, and 42nd of his minor league career, was a mammoth blast at Five County Stadium in Zebulon, N.C. that smashed a light bulb on the outfield light tower. Here is the description from Potomac Nationals Web site: "Keyes' majestic, Ruthian blast was a high-arching drive that collided with a band of bulbs on the left field...

The Oakland Athletics have already posted their lineup for tonight's series opener against the Orioles. For the Athletics Coco Crisp CF John Jaso C Seth Smith DH Jed Lowrie SS Brandon Moss 1B Chris Young LF Josh Reddick RF Josh Donaldson 3B Eric Sogard 2B Jarrod Parker RHP Reddick batted .343 with two homers and seven RBIs in eight games against the Orioles last season. The A's haven't lose a season series to the Orioles since 1998. The Orioles have lost 34 of their last 45 games in...

The Orioles begin a four-game series tonight and 11-game road trip against the Oakland A's. The A's have a 13-9 record while the Orioles are 12-9. But while Oakland has lost five of its last six games in series against Tampa Bay and Boston, Oakland has gone 6-0 against the Houston Astros who are in their first season in the American League. Later this year it could be that the Orioles will be battling with Oakland for a wild-card berth. This season the A's will play Houston 19 times and...

In desperate search of some more offense, Davey Johnson has inserted Steve Lombardozzi into today's Nationals lineup and moved Jayson Werth into the cleanup spot. Lombardozzi, who is off to a really strong start to 2013, batting .345 in 29 at-bats, will play third base and hit second in the new-look Nats batting order. Werth will hit fourth, with Adam LaRoche moving down to fifth in the lineup. Danny Espinosa, batting .155 on the season, remains in the lineup, batting seventh. Rookie...

Zach Britton is still listed as tonight's starter for Triple-A Norfolk. If he isn't a late scratch, he won't be starting for the Orioles on Monday. Update: Zach Clark (UMBC) is now listed as Norfolk's starter tonight instead of Britton. Feel free to speculate. The assumption here is that Britton will be in the Orioles' bullpen the next few nights and will start Monday if he isn't used in relief for an extended stretch. Update II: Britton is definitely in Oakland and he will take Josh...

On Sunday, Jake Arrieta started on the mound for the Orioles. One would have thought after a successful spring training, he would finally figure it out after several seasons in the majors. From the looks of things, he still may not have. After his performance against the Los Angeles Dodgers, Arrieta was again optioned to Triple-A Norfolk for seemingly the umpteenth time in the last couple of seasons. Sitting in the stands Sunday, I wondered how a guy who looks like your prototypical power...

Following Tuesday night's loss to the Cardinals, a defeat which was, at the time, the Nationals' third in a row and eighth in 11 games, a handful of Nats players sat around in the clubhouse and vented. It was pretty late at the time. Media members and most players and coaches had left. But Jayson Werth and a few of his teammates stuck around, letting their frustrations out and bouncing ideas off each other. "Just airing grievances," Werth said. "Just talking out, just complaining really,...

When I looked at a particular Manny Machado stat, I had to do a double take. But there it was staring back at me on my computer screen. When he is hitting with runners in scoring position and two outs this year, Machado is batting .750. He is 6-for-8. But he doesn't just deliver clutch singles in those spots. He has a double, a triple and two homers along with 11 RBIs. That is good for an OPS of 2.653. Turns out this kid is pretty good. Wonder how good he'll be after he turns 21? In the...
