Mize (hamstring) threw a bullpen session Tuesday that was deemed successful by manager A.J. Hinch, Evan Woodbery of MLive.com reports.
Mize's official return has not yet been announced by the Tigers, but it appears that he should be lined up to start Friday versus the Red Sox. The right-hander had a rehab outing Saturday, striking out seven in 4.2 innings while surrendering three earned runs. If he is able to make his return Friday, it will mark Mize's first big-league start since June 30.
