SCOTTSDALE, Ariz. -- A great day by some players battling for reserve positions with the Rockies was overshadowed by a big Dodgers' comeback on Saturday, and a walk-off homer by Rockies outfield prospect Tim Wheeler, a blast that gave Colorado an 8-6 victory.
Rockies outfield candidate Andrew Brown homered and doubled, and he wasn't alone. Fellow outfield competitor Tyler Colvin hit a two-run blast, and Eric Young Jr., who could see time in the infield and outfield if he makes the team, singled twice and drove in a run.
Rockies right-hander Jeremy Guthrie held the Dodgers to one run and four hits in 4 2/3 innings, with two walks and two strikeouts. Guthrie, who also drove in a run on a fielder's choice grounder, left with two out and two on in the fifth.
Right-handed setup man Matt Belisle forced an Adam Kennedy grounder to end that inning and pitched a strong next inning, which he finished by forcing a double-play grounder.
Dodgers prospect Nathan Eovaldi started and held the Rockies scoreless, on four hits with one strikeout, for three innings. Dodgers right fielder Andre Ethier doubled twice. Following his second double, which came in the fourth inning, he came around to score on a base hit by Tony Gwynn Jr.
Brown, acquired from the Cardinals in October, homered off of Dodgers reliever Ryan Tucker in the sixth inning.
Rockies lefty reliever Rex Brothers gave up a run with one out in the eighth on a Josh Fields single, but he worked Tony Gwynn Jr. into a line-drive double play to escape.
In the bottom of the frame, following a Wilin Rosario double, Tyler Colvin laced a two-run homer to left field off of Dodgers reliever Will Savage to push the Rockies' cushion to 6-2.
In the ninth, the Dodgers rallied for four runs to tie the game off of Rockies closer Rafael Betancourt. Tim Federowicz, Lance Zawadzki, Jeff Baisley and Trent Oeltjen each drove in one run, before Wheeler finished matters in the bottom of the ninth with his blast to right-center.
Dodgers up next: Chris Capuano starts on Sunday for the Dodgers against Dan Haren and the Angels, in a 1:05 p.m. PT game at Camelback Ranch in Glendale, Ariz. Relievers following Capuano will be Angel Guzman, John Grabow, Mike MacDougal and Wil Ledezma.
Rockies up next: Starting rotation hopeful Tyler Chatwood will start for a split-squad team that will play the Padres on Sunday at 2:05 p.m. MT at Tucson Electric Park in Tucson, Ariz. Third base prospect Nolan Arenado and outfield competitors Charlie Blackmon and Tyler Colvin are scheduled to make the trip. Lefty Josh Outman will start against the Mariners in Peoria, Ariz., with most of the Rockies' regulars scheduled to play. Third baseman Casey Blake hopes to return after missing six days with a sore muscle in his neck.
