Astros news: Outfielder Alex Presley claimed off waivers, Raul Valdes designated for assignment

On Thursday, the Astros announced a roster move that shook up its 25-man roster slightly. Houston claimed outfielder Alex Presley off waivers and designated left-hander Raul Valdes for assignment.

With the Valdes DFA, Houston opens up a spot on the 40-man roster for Presley, who played the past four sesaons for the Twins and Pirates. The 29-year-old hit .276/.313/.373 between the Twins and the Pirates last season with three home runs and one steal.

Presley has spent most of his big-league time in left field, but can play both center field and right field in a pinch. He likely fills the versatile fourth outfielder role and can back up all three spots.

Last season, Presley was included in a trade between the Pirates and the Twins for first baseman Justin Morneau. The deal also included a player to be named that turned into Duke Welker.

Houston now has 13 position players and 12 pitchers on its roster, with Kevin Chapman as the only left-handed reliever.

Valdes, 37, was the latest candidate in the game, "Who's the 40th man on this Astros roster?" Claimed from the Phillies this winter, he's been cut in commenter scenarios more times than I can count.

What do you think? Will Presley provide value as a fourth/fifth outfielder? Will his decent defense translate into a backup role?
