Darnell McDonald slugged a three-run homer and the Cubs held on for a 4-2 win over the Pirates in the season finale at Wrigley Field. McDonald went 3-for-4 with his first homer of the season. Jake Arrieta earned his fourth win of year, throwing six innings of four-hit, one-run ball. Kevin Gregg struck out the side in the ninth to earn his 33rd save as the Cubs snapped a three-game skid. Francisco Liriano took the loss after allowing four runs in five-plus innings. Starling Marte and Justin Morneau had two hits apiece for Pittsburgh, which fell three games behind St. Louis for the NL Central lead.
The Cubs will be in St. Louis Friday night.
