Jeff Locke fired seven scoreless innings Sunday in the Pirates' victory over the Astros. Locke looked excellent against the hapless Houston offense, yielding only three hits and two walks. He's now 4-1 with a cool 2.73 ERA and 1.14 WHIP in 52 2/3 innings this season, but some regression should be expected. Locke will face off against the Brewers next.
