Sammy Sosa moved closer to becoming the fifth player with 600 homers Wednesday night when he hit No. 597 in the fourth inning of the Rangers' game against the Devil Rays at Disney World. The two-run, opposite-field shot off left-hander Casey Fossum also extended Sosa's major league record for most ballparks homered in to 45. It was Sosa's ninth homer of the season.
