Astros signed Peter Lambert to a minor league contract.

Lambert is returning to the U.S. after going 3-11 with a 4.26 ERA and a 104/52 K/BB in 116 1/3 innings for the Yakult Swallows of Japan last season. Prior to that, he’d spent his entire career in the Rockies organization, going 8-19 with a 6.28 ERA in 35 starts and 39 relief appearances over parts of five major league seasons.
