DETROIT -- There's a good bit of doubt in Detroit about just what kind of pitcher Jordan Zimmermann will be in 2017.
The Tigers hope the right-hander can be the pitcher this April that he was last April, when he went 5-0 with a 0.55 ERA to get named American League Pitcher of the Month.
His season steadily unraveled after that and Zimmermann, bothered by side and neck injuries, was 9-7 with a 4.87 ERA for 19 games, which included one relief appearance.
Zimmermann will make his first start of the season Saturday against Boston, who will oppose him with left-hander Eduardo Rodriguez.
