Battling for the Mets' fifth-starter's job that Daisuke Matsuzaka has been favored to win all spring, Mejia held the Nationals to one run in five innings, striking out six. He came up lame covering first base in the fifth, prompting a visit from the Mets' training staff, but the issue turned out to be nothing more than a bunion on his right foot and Mejia stayed in the game.
The only run against Mejia scored in the first inning, after umpires overturned a caught stealing call that would have resulted in a bases-empty, two-out situation. Instead, Nationals manager Matt Williams asked for a replay review of Bryce Harper's stolen-base attempt, the call was overturned and Harper eventually scored on Ryan Zimmerman's RBI infield single.
With that run supporting him, Roark outpitched Mejia until the fifth, when he walked leadoff man Curtis Granderson, threw a two-out wild pitch and gave up Andrew Brown's RBI single. The rally tied the game at 1 but did not do much to spoil the final line of Roark, who gave up just one other hit with four strikeouts in 5 2/3 innings.
Granderson gave the Mets the lead two innings later with a two-run homer off Nats reliever Drew Storen. It was Granderson's third homer of the spring, but his first since March 4.
Up next: Matsuzaka will make his final Grapefruit League start when the Mets host the Cardinals for a 1:10 p.m. ET game Monday on MLB.TV in Port St. Lucie. Matsuzaka is also in line for a tune-up start during one of the Mets' exhibition games against the Blue Jays next week in Montreal, assuming he wins the fifth-starter's job.
