SAN FRANCISCO -- One reason the Giants are looking up at the rival Dodgers in the National League West race? The teams' performances against the Rockies, owners of the NL's worst record.
With a 3-2 loss to the Rockies inside AT&T Park on Monday night, the Giants dropped to 4-8 against Colorado this season. The Dodgers -- who will wake up Tuesday with a five-game advantage in the NL West -- are 9-4 against the Rockies.
It was the home team that looked more like one of baseball's worst teams Monday.
The Giants set the tone for their sloppy showing during the game's first at-bat. Charlie Blackmon reached on a routine grounder to second after a soft toss from Joe Panik forced Buster Posey off the base. Starter Jake Peavy's pickoff attempt after Blackmon stole second went errant, so Blackmon advanced to third and later scored on a sacrifice fly from Justin Morneau. Three innings later, things really got ugly for the Giants.
Drew Stubbs reached base and was awarded second after a wild throw from Brandon Crawford landed in the Colorado dugout. According to manager Bruce Bochy, Crawford tried to do too much when he committed another error one batter later, which allowed Stubbs to advance to third. Peavy then balked on a Morneau steal attempt, which scored Stubbs.
"I was just picking my leg up; Morneau couldn't have timed it any better. As I was picking my leg up, he was starting to go," said Peavy, who allowed three runs (one earned) on six hits and struck out five in seven innings. "You're going to home plate and then you hear 'Step off,' and I tried to hop off the back of the mound.
"Crazy night, all the way around."
A sacrifice fly by Corey Dickerson later in the inning gave the Rockies the lead. Four innings in, the Giants had four errors, which tied a season high. The blunders gave Crawford 20 errors on the season, most in the Majors among shortstops.
"It was a little awkward," Bochy said of the early struggles, which he said were the most disturbing of the handful of disheartening happenings Monday night.
When it was all said and done, Bochy was ejected, Peavy was nearly tossed for a second consecutive game, and the Giants' lead on the Braves for the NL's second Wild Card spot was slashed to a half-game.
"We certainly could've been better all the way around tonight, starting with me," Peavy said. "Frustrating night, for sure."
Even against an injury-depleted Rockies team, four errors and a balked-in run are hard to overcome. Especially when the Giants' offense isn't much prettier, which was the case Monday.
A Posey single scored Angel Pagan to tie the game at 1 in the first, and Andrew Susac hit a home run where home runs rarely go inside AT&T Park -- into the center-field bleachers -- to give the Giants a 2-1 lead in the second.
Rockies lefty Tyler Matzek -- who entered the game with a 5.38 ERA -- held the Giants to those two runs in seven innings. The Giants were 1-for-6 with runners in scoring position. Never were those shortcomings more apparent than in the bottom of the fourth, when Michael Morse hit a one-out triple but was stranded at third.
With the loss, the Giants are now just 10-24 in their last 34 home games, and the Rockies have won a franchise-best four consecutive games in San Francisco.
"Overall just not a well-played game," Bochy said, "and it caught up with us."
The same will be said about these losses to the Rockies if the Giants fail to qualify for October.
