Despite allowing seven hits, Jeff Locke blanked the Tigers for 5 1/3 innings on Thursday. Locke has pitched 18 1/3 scoreless innings in his last three starts, and he's now had five starts this season in which he hasn't allowed a run. No other pitcher in baseball can say that. Six pitchers have had four such outings: Jorge De La Rosa, Clayton Kershaw, Hiroki Kuroda, Paul Maholm, Justin Masterson and Shelby Miller. Locke can't keep up this pace for much longer, but he's a big reason the Pirates have been baseball's most pleasant surprise so far this season.
