LOS ANGELES -- Against every other team in the National League this year, Dodgers first baseman James Loney can't seem to buy so much as an extra-base hit -- much less a home run.
But for whatever reason, whenever Loney sees a Colorado pitcher, he dons his best Prince Fielder impression.
Loney only has eight home runs this year, but six of them have come against the Rockies. Loney took a Rafael Betancourt changeup deep for home run No. 6 with one out in the bottom of the ninth Saturday to force extra innings, where Matt Kemp gave the Dodgers a 7-6 win with a walk-off home run in the 11th.
Kemp's home run ended a long, hot day at Dodger Stadium. It was 97 degrees at fist pitch and the heat forced second base umpire Bob Davidson to exit the game before the start of the bottom of the fourth due to dehydration. Davidson received an IV and did not return.
While it might not be shocking to see Loney get a big hit against the Rockies, the fact that Betancourt was on the other end of the blast is noteworthy. The run was the first Betancourt had allowed in August, snapping a 10-inning scoreless streak.
"I think I threw a bad pitch right there -- changeup like middle of the plate," Betancourt said. "He hit it hard and didn't miss."
The loss marks the second straight night the Rockies blew a one-run lead late in the game.
On Friday, two balks led to a six-run seventh inning as the Dodgers rallied to a 6-1 win. Saturday, the Rockies suffered through a similar implosion when Los Angeles scored five in the bottom of the sixth to rally from a 4-0 hole.
"If we had executed a little better we would have been done 1 hour, 30 minutes ago," said a frustrated Jim Tracy after the game. Tracy had every reason to be down, considering the number of opportunities the Rockies wasted throughout the day.
They failed to score with runners on second and third with no outs in the second against Dodgers starter Chad Billingsley, and then there were the two costly defensive miscues that squandered a 4-0 lead.
"Big key to the game was obviously in the sixth inning," Tracy said. "We didn't catch the ball in a couple of situations. It ended up leading to five runs."
Colorado entered the bottom of the sixth up 4-0 and appeared in control as right-hander Kevin Millwood turned back the clock and delivered what Tracy described as a "tremendous outing."
The 15-year veteran, who just a month ago was pitching in the Red Sox farm system, retired the first seven batters and only allowed two Dodgers to reach scoring position through the first five innings, but he ran out of gas in the sixth. Aaron Miles and Loney hit back-to-back singles with one out, and Tracy called Matt Belisle out of the bullpen to replace Millwood.
Belisle got Kemp to ground to third baseman Kevin Kouzmanoff, but Miles scored the Dodgers' first run when Chris Iannetta couldn't handle Kouzmanoff's throw home.
The Rockies were burned by another fielding error on the next play when Kouzmanoff blew a tag at third. Casey Blake later tied the game with a two-run double and Jamey Carroll gave the Dodgers their brief one-run lead with an RBI single.
Only three of the five runs scored by the Dodgers that inning were earned.
"What took place in the sixth inning defensively for us ... that's where the game lies," Tracy said. "We didn't catch a couple of balls in the sixth inning that would have diffused the sixth inning, and I don't think they would have scored five. If we get the out at home plate they may not have scored any."
It appeared the Rockies were off the hook when Troy Tulowitzki hit his second two-run home run of the game, this time off Hong-Chih Kuo, to put Colorado back up one in the top of the seventh.
But the Rockies were unable to add to their lead, leaving the door open for the Dodgers' ninth-inning comeback.
Tulowitzki and Gonzalez drove in all six of Colorado's runs.
Gonzalez went 4-for-6 with two runs and two RBIs, while Tulowitzki added four RBIs via the two homers.
"You can't ask for a better offensive day than you got from the right fielder and the shortstop," Tracy said. "They get half the hits and all the RBIs."
Gonzalez entered the Rockies' record books in the top of the third when he followed Mark Ellis' leadoff double with an RBI single to right field. The hit made it 11 consecutive games with an RBI for Gonzalez, moving the right fielder past Vinny Castilla for the longest streak in Colorado history.
The single also extended Gonzalez's hitting streak to 14 games.
