The Nationals are shaking things up.
After making a bevy of roster moves before Tuesday's game against the Mets, which included activating Jayson Werth, placing Danny Espinosa on the disabled list and recalling top infield prospect Anthony Rendon from Triple-A Syracuse, the Nats got a 3-2 walk-off win.
"It's all about putting the best 25 guys out there at this particular time to help you win games," general manager Mike Rizzo said. "Decisions would be different if we had a full healthy team throughout the whole season and we were hitting on all cylinders. But we're not healthy.
"We're trying to piece together a lineup to help us scratch out and score enough runs to win some games, so we felt to get healthy players in there to give us a chance to be as good offensively as we can."
Washington will see if that lineup pays off again on Wednesday as the team faces the Mets at Nationals Park.
After taking a tough-luck loss on Thursday to the Orioles, Dan Haren will be on the hill for the Nats. He allowed just two runs on eight hits in 7 1/3 innings, but Washington could muster only three hits in a 2-0 loss.
Meanwhile, Dillon Gee gets the nod for the Mets after dazzling in his best start of the season on Thursday against the Yankees.
Tossing a season-high 7 1/3 innings, the right-hander allowed only one run on four hits for his third win of the season. He also struck out a career-high 12 in the contest.
It marked a much needed win for Gee, who came into the game winless in his last four contests with a 6.34 ERA on the season.
"I'm not stupid. I know that that many bad outings in a row, you're probably hanging on a thread," Gee said after the game. "I needed that on so many levels, it's crazy."
Mets: Familia to have elbow surgery
• The Mets announced on Tuesday that reliever Jeurys Familia will undergo surgery Wednesday to remove bone spurs and loose bodies from his right elbow.
Familia, 23, posted a 3.48 ERA in eight games this season, before the Mets placed him on the disabled list May 12 with right biceps tendinitis.
Familia ranked 90th on MLB.com's Prospect Watch last year, joining Zack Wheeler (28th) and Matt Harvey (38th) as one of baseball's most highly touted starting pitching trios.
Nationals: Strasburg feeling better
• Washington right-hander Stephen Strasburg, who suffered a mild lat strain on Friday against the Braves, told pitching Steve McCatty that he is feeling better, according to manager Davey Johnson.
Strasburg will throw a bullpen session Wednesday and, if everything goes according to plan, could pitch against the Twins on Saturday.
"We'll see how he feels, but he did feel a lot better yesterday," said Johnson.
• Nationals catcher Wilson Ramos, who is on the disabled list with a left hamstring strain, said he is running and hitting without any problems.
• In his one start against the Nats back on April 21, Gee allowed just three hits in 5 2/3 innings for his first win of the season.
• Mets left-hander Jon Niese will throw his anticipated side session Wednesday afternoon, which will determine whether he will be able to make his next start Saturday against the Marlins. Niese has not thrown since the Mets shut him down last week because of left biceps tendinitis.
