DENVER – Alex Cobb pitched effectively into the seventh inning, withstanding three solo homers by Colorado and helping the Tampa Bay Rays beat the Rockies 8-3 Sunday.
Jose Lobaton, Ryan Roberts and Kelly Johnson each drove in two runs for the Rays. Tampa Bay took two of three and won a series at Coors Field for the first time in four visits.
Cobb (4-2) went 6 2-3 innings and allowed eight hits. Nolan Arenado hit a two-out homer in the seventh that pulled the Rockies within 6-3, a day after the rookie had a grand slam.
