Pirates at Rockies

The Pittsburgh Pirates are on the verge of clinching a National League playoff spot as they visit the Colorado Rockies in Tuesday's second contest of a four-game set. Pittsburgh posted a 9-3 victory in the series opener and will sew up at least a wild-card berth if it defeats Colorado and San Francisco loses to San Diego.

The Pirates possess a two-game advantage over the Chicago Cubs for the right to host the wild-card game and reside four games behind the first-place St. Louis Cardinals in the NL Central. Pittsburgh, which has won three straight games, smacked 15 hits in the opener with left fielder Starling Marte — who homered — and shortstop Jordy Mercer each going 4-for-5 with two runs scored and two RBIs. Third baseman Aramis Ramirez slugged his 17th homer and is 4-for-11 with two homers and six RBIs against scheduled Rockies starter Chris Rusin. Colorado shortstop Jose Reyes is just 5-for-32 over his past eight games and he traditionally struggles (2-for-21) against scheduled Pittsburgh starter J.A. Happ.
