Pence's double in the eighth helped the Giants equal a mark accomplished four times since the Giants moved to San Francisco after the 1957 season. Denard Span hit his first homer since April 4 as part of a 17-hit attack.
The usually mild-mannered and fast-working Cueto became a little agitated in the third after Gerardo Parra called a last-second timeout. When Parra lined into an inning-ending double play, Cueto appeared to say something to Parra, with Parra glaring back. It didn't escalate.
Chris Rusin (1-3) allowed six runs and 11 hits in five innings.
Rusin moved into the starting rotation for Jorge De La Rosa, who has been sent to the bullpen. Rusin hung an 83 mph cutter to Span in the fourth, the first homer he's allowed in 41 2/3 innings dating to last season.
Pence had a big afternoon with a career-high three doubles -- with each driving in a run.
Handed a lead after Cueto's solid performance, the Giants bullpen made it hold up. The only run allowed was a homer by Carlos Gonzalez in the eighth estimated to have gone 456 feet had it landed unimpeded. The day before, San Francisco's bullpen squandered a late lead before the team rallied.
It was a rather forgettable day for Parra, who had a baserunning blunder in the second. He attempted to tag up from second on a fly to center, only to be thrown out at third by Span.
Later, Parra got into a little spat with Cueto. Parra held his hand up for time, which was granted, and so Cueto waited. Parra did it again and Cueto threw his hands up in exasperation, before stepping off the mound and taking a stroll to cool down. He then retired Parra and appeared to say something as Parra ran down the baseline.
Cueto struck out Parra when they faced each other in the sixth. Cueto didn't make eye contact with Parra.

Giants: RHP Jeff Samardzija (7-2) is to make his 11th start of the season when the Giants open a four-game series in Atlanta on Monday. He is 2-1 with a 2.81 ERA in 10 games (four starts) against the Braves.
Rockies: RHP Chad Bettis looks to get back on track Monday against Cincinnati. Bettis threw a season-low 4 2/3 innings in a loss at Boston last Wednesday.
