Padilla (7-2) allowed five runs and seven hits in six innings to win his fifth straight decision and stop Tampa Bay’s four-game winning streak. The right-hander walked four and struck out a season-high 10.
Hamilton, the former No. 1 overall pick in the draft whose career with the Rays was derailed by drug addiction and injuries, had a RBI double off Andy Sonnanstine (6-3) in the first. He added his second grand slam of the season in the eighth off J.P. Howell.
The five RBI matched a career best set May 16 against Houston and boosted Hamilton’s season total to a major league-leading 58. He’s also batting .329 with 13 homers after hitting 19 with Cincinnati in 2007, his first season in the big leagues.
The 27-year-old outfielder is 4-for-6 and has driven in 14 runs with the bases loaded this year.
Brandon Boggs had an RBI single in the first and a two-run double in the second, when the Rangers scored five unearned runs off Sonnanstine to take a 7-0 lead that Padilla was barely able to protect.
