Yahoo! Sports' Tim Brown reports that Brian Wilson is hoping to join someone's major league bullpen by mid-August. Brown says Wilson is drawing interest from four National League teams and one American League club. The Pirates, Diamondbacks, A's, Giants, Phillies, Rangers, Rockies and Cardinals were among the teams who scouted his throwing session this past Thursday. Wilson reportedly looked good in the session and should be used towards the back-end of someone's bullpen, though it remains to be seen whether he'll receive any offers to close.
