At St Petersburg, Florida, Scott Kazmir allowed four hits in six innings to outpitch Roger Clemens and earn his first win at home in more than a year.

He won at Tropicana Field for the first time since pitching a two-hit shutout against Boston on July 3, 2006. He was 0-4 in 14 starts during the stretch of futility at home.
Josh Wilson and Dioner Navarro each drove in two runs for Tampa Bay, which won for just the second time in 16 games.
