The Astros have signed right-handed reliever Kyle Farnsworth, the team announced. He will join their bullpen immediately and be available for Saturday's game.

Farnsworth, 38, was roommates with Astros manager Bo Porter back during his minor league days. He can earn more than $1 million with incentives, according to Jon Heyman of CBSSports.com.

Farnsworth was released by the Mets a few days ago despite spending a few weeks as their closer. He had a 3.18 ERA with a 1.41 WHIP and three saves in 17 innings for New York before getting cut.

Righty Paul Clemens was sent to Triple-A in a corresponding roster move. The 26-year-old has a 4.08 ERA and a 1.47 WHIP in 17 2/3 innings for the Astros this year.

Houston comes into Saturday with the worst bullpen ERA (5.56) and WHIP (1.59) in all of baseball.
