Trying to boost one of the weakest lineups in the American League, the New York Yankees acquired third baseman Chase Headley from the San Diego Padres on Tuesday for rookie infielder Yangervis Solarte and minor-league pitcher Rafael De Paula. The switch-hitter was batting .229 with seven homers and 32 RBIs but has a .339 average with six extra-base hits in 13 games since July 4. Texas Rangers catcher Geovany Soto has been placed on the 15-day disabled list with a strained right groin, less than a week after he returned from right knee surgery.
