Matt Olson’s incredible rookie season is, in all probability, over.

The Oakland Athletics rookie first baseman was diagnosed with a Grade 2 hamstring strain after undergoing an MRI Monday and A’s manger Bob Melvin didn’t sound optimistic when addressing his player’s status.

“He’s having a tough time moving around right now, so if I’m handicapping it it’s probably going to be a tough chance for him to come back,” Melvin told reporters following a 7-1 loss to the Seattle Mariners. “Usually these things can be upwards of a couple weeks. Based on the fact that we only have six games left it’s going to be tough for him.”

The 23-year-old sustained the injury while reaching for an out in the seventh inning of Sunday’s game against the Texas Rangers.

Olson has been a revelation in 2017, notching 24 home runs in 189 at-bats. The A’s went 21-15 with Olson in the starting lineup since he was permanently recalled on Aug. 8 from the triple-A Nashville Sounds of the Pacific Coast League.
