Pirates optioned RHP Jered Hughes from Triple-A Indianapolis.
He'll head back down to the minors now that Jose Contreras is back from the bereavement list. Hughes has a 4.61 ERA and 13/9 K/BB ratio over 13 2/3 innings this season and should get another shot in the Pirates' bullpen before long.
Jason Grilli earned his 17th save of the season Sunday in the Pirates' 1-0 defeat of the Astros.
Grilli retired all three batters he faced, needing only 10 pitches. He's been probably the best closer in baseball through the first seven weeks of the 2013 season, boasting a 0.92 ERA, 0.66 WHIP and 31/4 K/BB ratio in 19 2/3 innings. He has not blown an opportunity.
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.
