The Detroit Tigers didn't technically need another starting pitcher at the trade deadline, but they went out and got two anyway. Detroit traded for Chris Paddack from the Minnesota Twins first, right before announcing that Reese Olson's regular season was over with a shoulder strain. Then the Tigers brought Charlie Morton over from the Baltimore Orioles on deadline day.
Troy Melton and Keider Montero could've slotted in at Nos. 4 and 5 in the rotation, but Melton was sent back to the bullpen and Montero was demoted to Triple-A instead.
Paddack and Morton were questionable acquisitions (which seemed to be the theme of Scott Harris' trade deadline).
