SAN FRANCISCO (AP) The Rockies and Giants combined to use a major league-record 25 pitchers, and Colorado finished off San Francisco 8-5 early Wednesday morning when Charlie Blackmon hit a three-run homer in the 16th inning.
The game lasted 5 hours, 31 minutes, with Giants manager Bruce Bochy making 12 pitching changes - hardly taking it easy in his final week on the job.
Blackmon's first hit of the night came in his eighth plate appearance and off Dereck Rodriguez (6-10) for his 31st home run.
Both clubs left the bases loaded in the 11th, and Colorado stranded 15 baserunners.
This wasn't even the longest game between the clubs this season. The Giants beat the Rockies 3-2 in 18 innings and 5:35 on April 12 - the longest game at Oracle Park since an 18-inning loss to Arizona on May 29, 2001. Colorado also played two games of 16 innings or more in 2006.
Sam Howard (2-0) pitched the final two innings for the win.
With the Cardinals and Diamondbacks also going long, it marked the first time since June 8, 2013 - Mets-Marlins and Blue Jays-Rangers - more than one game went at least 15 innings the same day, according to MLB Stats.

Evan Longoria hit a tying homer in the eighth off Carlos Estevez. Longoria became the third Giants player with 20 homers, and for much of the game the ball carried on an unseasonably warm late-September night. First-pitch temperature was 78 degrees.
Garrett Hampson hit his second homer of the game to put Colorado ahead in the eighth after losing starter Jeff Hoffman to a knee injury from a line drive, but the Giants kept pushing.
Trevor Story connected for his 34th homer after a pair of strikeouts to begin his night against Madison Bumgarner, who might have made his final start for San Francisco, though he was still scheduled to pitch Sunday's season finale. Bochy hinted there still could be a change.
Bumgarner drew big cheers as he walked to the mound to start the game, then struck out nine and walked two over seven innings, allowing four runs on six hits.
Hoffman took a line drive off his right knee in the fourth inning and was carted off the field. Alex Dickerson's sharp single hit squarely on Hoffman's knee and the pitcher went down writhing in pain, and the ball ricocheted toward San Francisco's dugout. He was down a little more than five minutes as athletic trainers from both teams tended to him on the mound.
Buster Posey hit a two-run homer in the bottom of the first for just his seventh home run and first in 123 at-bats since July 31 at Philadelphia. Bumgarner added a homer of his own but the lefty remains winless in five starts since beating the Padres on Aug. 30. The Giants have lost his last four outings.
Ian Desmond hit a two-run homer in the fourth after Bumgarner hit Blackmon on the left hand area with a pitch to start the inning.
Bochy began what he knows will be an emotional final week on the dugout's top step. Fans stood and cheered when his picture showed on the big scoreboard during pregame introductions.
"It's going to be tough to say bye," Bochy said.
