Corey Dickerson hit a tiebreaking homer with two outs in the top of the 10th inning, and the Colorado Rockies avoided a seventh straight loss to the Arizona Diamondbacks with a 5-3 win Sunday.
Dickerson, hitless in four previous at-bats, sent an 0-1 pitch from Oliver Perez (2-2) into the pool deck in right field for his 14th home run of the season.
The Rockies snapped a three-game skid overall and won for just the second time in 10 games.
Wilin Rosario, whose throwing error allowed the Diamondbacks to take a 3-2 lead in the fourth, hit a solo home run to tie the game in the sixth. Rosario singled in a run in the 10th to pad the Rockies' lead.
Ben Paulsen, called up Sunday to replace the injured Carlos Gonzalez on the roster, hit his first major league home run in the second, evening the score at 2.
