Martinez, an outfielder who was claimed off waivers from the Mets in January, made his first Grapefruit League start for the Astros on Sunday against the Nationals and went 2-for-2 with a three-run homer and a walk as the team's designated hitter.
"I need the opportunity to play a couple of games and maybe they want to see me and how I play in the outfield and how I run the bases," said Martinez, a former top prospect of the Mets whose career has been marred by injury. "I'm working hard every day. It's simple. It's like anything -- just enjoy the game and play hard."
The Astros also got homers on Sunday from catcher Chris Snyder, who belted a solo shot off Nationals pitcher Stephen Strasburg, and left fielder J.D. Martinez, who went 1-for-2 with a three-run blast and a bases-loaded walk en route to four RBIs in his first start of the season.
"I was just trying to see pitches and came up in that spot and was trying to hit the ball," J.D. Martinez said. "[Pitcher Tom Gorzelanny] was just trying to come in and he left it in the middle instead of coming in, and I was able to get to it."
