LF - Justin Upton, Detroit Tigers
Season Stats: .271/.356/.507 (129 OPS+), 15 HR, 54 RBIs, 3.0 WAR
It’s been a dreary season for the Tigers and an uncharacteristically bad one for star Miguel Cabrera, but Upton has avoided the kind of horrendous slumps that have hounded his career to become the team’s most stable offensive option in 2017. If he maintains his newfound consistency, he’s on his way to his best season since ‘11, when he finished fourth in the NL MVP voting. All due credit to the Orioles’ Trey Mancini, who would likely be the Rookie of the Year favorite if not for Judge and is currently batting .312/.356/.551 with 14 homers and 43 RBIs, but Upton’s resurgence is the only thing that has kept the Tigers from blowing up the entire operation (which they still might).
