The Colorado Rockies scored five runs in a wild first inning, then held on to beat the San Diego Padres, 7-4, in the first game of the weekend series at Petco Park.
The first inning scoring was fueled by consecutive two-run doubles belted by rookies Wilin Rosario and Jordan Pacheco. Later in the game Chris Nelson and Charlie Blackmon added solo home runs for the Rockies.
Colorado starting pitcher Tyler Chatwood wasn't able to take advantage of the run support, though. After giving up a grand slam in the first inning to San Diego first baseman Yonder Alonso, Chatwood only pitched 3⅔ innings. Guillermo Moscoso (3-1) earned the win in relief while Rafael Betancourt closed out the ninth for his 29th save of the season.
The two teams continue their series on Saturday at 6:35 p.m. MT
