Yankees' Soriano scratched with thumb injury

New York Yankees outfielder Alfonso Soriano was scratched from Saturday's starting lineup against Boston because of a thumb injury.

Soriano has been the Yankees' top offensive threat since joining the club in a trade with the Cubs back in July. He has clubbed 15 homers and driven in 47 runs in 46 games for the Yankees.

New York is already short an outfielder after Brett Gardner went down with a strained oblique muscle on Thursday in Baltimore. Gardner could miss the remainder of the regular season.

Vernon Wells will replace Soriano in the left and will bat fifth.
