What It Means:

Kiermaier broke two metacarpal bones in his glove hand Saturday while trying to rob James McCann of a hit and is expected to be sidelined for the next 8-10 weeks. Mikie Mahtook started in center field on Monday night and Brandon Guyer drew the nod there Tuesday afternoon. Tampa Bay can feature a number of different looks, but Kiermaier is one of the best defenders in baseball at any position. It's a huge loss.

Kiermaier was slashing .236/.307/.447 prior to the injury, with five home runs, six steals, and a .325 wOBA in 137 plate appearances this season. Known more for his glove, Kiermaier had a 14.1 Ultimate Zone Rating in runs above average per 150 Defensive Games, which ranks fifth-best among center fielders this season.
