LHP Sean Burnett went for an MRI on his back after feeling stiffness. He missed about 10 days late last spring with a lower back injury. Burnett, 30, went 1-2 with two saves and a 2.38 ERA in 70 relief appearances for the Nationals last year. He signed a free agent deal with the Angels in December, two months after he underwent left elbow surgery. --OF Mike Trout said he arrived in camp 10 pounds heavier than he was last season, but neither Trout nor manager Mike Scioscia anticipated the extra weight having any impact on his game. Trout, 21, was the AL Rookie of the Year in 2012, and he finished second in AL MVP voting. --OF Josh Hamilton said he has always arrived at camp at about 245 pounds, but this year he came in at 225 and planned to maintain his weight all year, rather than seeing his weight -- and strength -- decrease during the season. Hamilton, 31, hit a career-high 43 homers for Texas last year.
