PHOENIX (AP) - Ian Kennedy pitched six innings to earn his NL-best 21st win and the Arizona Diamondbacks routed the San Francisco Giants 15-2 on Saturday night, eliminating the defending World Series champions from the postseason picture.
Gerardo Parra had two hits and four RBIs for the Diamondbacks, who scored six times in the first and tied their single-highest scoring game of the season. Ryan Roberts drove in three runs.
Arizona also matched a franchise record with 13 walks one night after it beat San Francisco 3-1 to clinch the NL West title. The Diamondbacks also had 13 walks in a 13-inning game against the Houston Astros on June 5, 2002.
San Francisco was eliminated from the wild-card race with the loss. The Giants fell behind Arizona when they lost to Pittsburgh on Aug. 10 and never regained first place in the division.
Kennedy (21-4) allowed two runs and five hits, struck out four and walked two. The right-hander is 6-0 with a 1.66 ERA in his last seven starts.
The Diamondbacks remained one game back of Milwaukee for the second-best record in the National League, with home-field advantage for the first round of the playoffs at stake.
Arizona scored six times in the first inning against Eric Surkamp (2-1), who walked four and recorded just two outs. Roberts and Parra each had a two-run single, and Kennedy capped the outburst with a two-run double.
The Giants experienced some bad luck on Parra's hit, with second baseman Mike Fontenot running into second base umpire Bruce Dreckman. The collision allowed the routine grounder to go into center field, scoring Paul Goldschmidt and Roberts.
The Diamondbacks added five more runs in the sixth, and the rout was on. Roberts had another run-scoring single, lumbering catcher Henry Blanco tripled home a run and pinch-hitter Sean Burroughs added an RBI single for an 11-2 lead.
Pablo Sandoval had two RBIs for San Francisco, which allowed a season high for runs.
The Diamondbacks improved to 92-66, tying for the third-most victories in franchise history. They won 100 in 1999 and 96 in 2002.
