White Sox's Reynaldo Lopez: Throws five perfect relief innings

Lopez (3-1) earned the win Friday over the Cubs. He threw five perfect innings and struck out seven.

The right-hander has bounced between the bullpen and the rotation this season. Lopez provided excellent length in a relief assignment after starter Dallas Keuchel was shelled for six runs (five earned) in the first inning of Friday's 17-13 crosstown slugfest. Through 34 innings, Lopez has a 1.59 ERA, 0.71 WHIP and 37:7 K:BB. He still threw just 59 pitches (40 strikes), but the 27-year-old has been an effective innings-eater in the bullpen while holding his own in four starts this year, as he's yet to allow more than three runs in any appearance.
