Mets 6, Pirates 5: R.A. Dickey became the first knuckleballer to win 20 games in more than three decades, tying his career-high with 13 strikeouts and David Wright broke a 3-3 tie with a three-run homer.
A 37-year-old knuckleballer who had never won more than 11 games in any previous season, Dickey (20-6) allowed three runs and eight hits in 72⁄3 innings, walking two and reaching double digits in strikeouts for the seventh time this season. He leads the NL with 222 strikeouts.
"I was not myself today for the most part," he said. "And then I'd come out for an at-bat and I would hear this kind of growing surge, and it really was neat. ... How could you not be motivated to go out there and give the fans and, well, your teammates and yourself all that you have?"
Rockies 7, Cubs 5: Jordan Pacheco and DJ LeMahieu each homered, leading host Colorado to a three-game sweep. Pacheco, Wilin Rosario and Chris Nelson had two hits apiece for the Rockies, who had 12 hits in their final home game of 2012.
