In the first two games against the Tigers, neither starter made it out of the sixth inning, but the bullpen put together six combined scoreless innings. Over the last six games, the bullpen has a 1.53 ERA.
But while the bullpen's performance has been encouraging, Gardenhire knows much of that success going forward hinges on the starters lowering their workload.
"If we want to keep it that way, our starters are going to have go deep," Gardenhire said. "You can't pitch three and four innings out of the bullpen and expect things to go rosy for you.
"You saw on the other side, Jim [Leyland] was talking about how his bullpen is beaten up a little bit. That happens, and that's why you need your starters getting into the second half of games. You can't expect to go three, four innings out of the bullpen very long before you're in trouble. But our bullpen is throwing great."
