Astros choose to pull Wandy from waivers

Could not complete deal with Rockies within 48-hour window

SAN FRANCISCO -- The Astros pulled left-hander Wandy Rodriguez back off waivers prior to Thursday's deadline to work out a deal with the Colorado Rockies, who had claimed Rodriguez off waivers 48 hours earlier. That means Rodriguez will remain with the Astros for the rest of the regular season.

The move certainly comes as no surprise, considering Houston general manager Ed Wade said Wednesday afternoon he expected Rodriguez to remain with the Astros. Rodriguez pitched against the Rockies on Wednesday and allowed six runs (four earned) in six innings and took a no-decision in Houston's 7-6 loss. He's 9-9 with a 3.41 ERA.

Rodriguez, 32, was the subject of numerous trade talks prior to last month's non-waiver Trade Deadline, but the Astros weren't able to get a deal done. They could try to trade him again this offseason and take advantage of what's expected to be a weak free-agent market for starting pitchers.

The sticking point for any deal involving Rodriguez is money. He signed a contract extension at the end of last year that will pay him $36 million over the next three seasons, which includes what would be a player option for 2014 if he changes teams.

Rodriguez is the last remaining Astros player to appear in the 2005 World Series.
