Pittsburgh @ Chicago preview

Last Meeting ( Jun 12, 2014 ) Chi. Cubs 0, Pittsburgh 4

Navigating through the top of the Pittsburgh lineup is a little more difficult these days and the Chicago Cubs are next to deal with Gregory Polanco and Co. when they host the Pirates on Friday to begin a three-game series. Polanco, a rookie right fielder, set a team record by hitting safely in his first nine career contests and is batting .378 with six RBIs and nine runs scored after recording two hits to help Pittsburgh (35-37) defeat Cincinnati 4-3 in 12 innings on Thursday and snap a three-game slide. Polanco, No. 2 hitter Starling Marte and No. 3 Andrew McCutchen are hitting a combined .376 with 23 RBIs and 20 runs scored since Polanco joined the lineup.

Chicago (30-40), which is 15-14 at Wrigley Field, starts a 10-game homestand after losing three of four in Pittsburgh before winning back-to-back series to finish its road trip 5-5. "Over the last two or three weeks, we've been playing pretty good baseball and bounced back," Cubs manager Rick Renteria told reporters. The Pirates' Charlie Morton has won three straight decisions and faces Edwin Jackson and the Cubs for the third time this season, with Pittsburgh winning all three.
