Wallace homers, Cedeno triples in Astros debut

Minor Leaguer Martinez limits damage, earns first Spring Training win

KISSIMMEE, Fla. -- Brett Wallace homered and Fernando Martinez had an RBI double and scored a run as the Astros beat the Marlins, 4-1, on Sunday afternoon at Osceola County Stadium in a game that was called in the fifth inning because of rain.

Minor League right-hander David Martinez, who spent most of last year at Class A Lancaster, got the start for the Astros and worked four innings, scattering eight hits to get the win. Jose Veras worked a scoreless fifth in his second game since returning from the World Baseball Classic.

Jacob Turner, competing for a spot in the Marlins' rotation, worked 4 2/3 innings, allowing four earned runs. He was removed from the game as the rain was starting.

Ronny Cedeno, who was signed by the Astros on Sunday, made his debut, starting at shortstop. He went 1-for-2 with a triple. Wallace's homer in the third put the Astros ahead 4-1, and it was his third of the spring.

Matt Dominguez scored Martinez on a sacrifice fly in the second to give the Astros a 2-1 lead.

Giancarlo Stanton drove in Juan Pierre with a single in the first, and Greg Dobbs went 3-for-3 with two doubles for the Marlins.

Up next: Right-hander Alex White continues his quest for a spot in the starting rotation when he takes the mound for the Astros' 5:05 p.m. CT contest on Monday against the Nationals in the first of three consecutive night games. White allowed three runs on seven hits and a walk in his most recent outing against the Mets. The game can be watched free on MLB.TV.
