Chapman was recalled from Triple-A Oklahoma City on Friday, MLB.com's Brian McTaggert reports. Chapman wasn't the sharpest during previous stints with the Astros earlier this season, allowing seven earned runs over 5.2 innings. His Triple-A numbers are respectable, however, as he owns a 1.23 ERA and a 64:25 K:BB ratio over 44 innings, saving a total of nine games for the RedHawks. Moreover, a 1.43 WHIP suggests he lives a bit dangerously, as he tends to allow at least a baserunner or two each appearance. He'll serve in middle relief for the Astros, providing left-handed bullpen depth.
