The Giants signed Dontrelle Willis to a minor league deal back in January and the Fresno Grizzlies, the Giants’ Triple-A affiliate, have added the lefty to their active roster, per the Grizzlies’ Twitter account.

Willis, 32, hasn’t pitched in the Major Leagues since 2011, but it hasn’t been for a lack of trying. Going into the 2012 season, Willis signed a minor league deal with the Phillies, but he was released during spring training. The Orioles grabbed him, and he made four appearances with Triple-A Norfolk. Willis announced his retirement on July 2, but he wouldn’t stay retired for long.

The Cubs signed Willis to a minor league deal in January 13, but Willis injured his shoulder in his first spring start and the Cubs released him. The Long Island Ducks of the Atlantic League signed him in April and he had good results, though against markedly inferior competition. Willis made the Atlantic League All-Star team, and the Angels signed him to a minor league deal in August. He posted more poor results at Triple-A.
