Detroit recently lost starters Anibal Sanchez (rotator cuff, 15-day DL) and Daniel Norris (oblique, 15-day DL), so they need bodies for the rotation. Enter Wolf, who is now 38 years old and heading to his 12th big-league organization. Clearly, he is a stop-gap measure for the Tigers at this time.

The Blue Jays never felt the need to purchase Wolf's contract this season, so at least they are giving him a chance to return to the big leagues. Toronto made a big move by landing David Price earlier, and may get Marcus Stroman (knee surgery, 60-day DL) back in September. Their rotation appears set.

Wolf was never a huge fantasy pitcher, so that obviously doesn't change now that he's almost in his 40's. Ignore him.
