Zimmermann is pitching like the frontline starter the Tigers signed a few years ago. He has allowed two runs over 20 innings in his last three starts with no walks and 20 strikeouts, including eight innings and 11 strikeouts to beat Texas.
Wood has been impressive since being recalled on June 30, particularly on Monday, when he inherited a two-on, one-out situation and stranded both runners on his way to 2 2/3 innings of scoreless relief.
