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.
