PITTSBURGH -- Gregory Polanco's 10th assist of the season was the rarest -- but also the easiest.
The Buccos right fielder was stationed shallow and toward the right-field line as Cubs pitcher Trevor Cahill stepped in to face Gerrit Cole leading off the top of the fifth inning in the opener of Tuesday's doubleheader at PNC Park, a 5-4 Pirates win.
The assist was also the season's 32nd for Pittsburgh outfielders, tops in the National League.
A half-inning later, Pirates third baseman Jung Ho Kang led off by lining a sharp single to right. Upon fielding the knock, right fielder Chris Coghlan sensed an opportunity to return the favor to the Bucs and quickly threw to first, but Kang was too quick.
