Blair has undergone arthroscopic surgery on his left knee, but is expected to be ready for spring training, Jane Lee of MLB.com reports.

Blair saw action in 11 games for the Athletics this season, but it appears a knee injury has kept him sidelined recently. He will now begin the rehab process in an attempt to crack the big league roster out of spring training in 2016.

Blair went 1-for-4 with an RBI and a run scored in a 10-6 loss to Houston on Saturday.

It's Blair's seventh game in the majors and it's been a struggle for the rookie. Blair has yet to record a multi-hit game and he has struck out 13 times in just 2- at-bats. With Josh Phegley currently nicked up, Blair may see regular starts for the last couple weeks of the season.

Blair hit a solo home run in a loss to the Rangers on Sunday.

With Stephen Vogt still missing action from a groin injury and Josh Phegley getting the afternoon off, Blair stepped in and hit his first major-league home run, driving a ball off Rangers' reliever Andrew Faulkner into the seats in the seventh inning. Blair certainly has some pop to his bat --- however that pop will mainly be relegated to spot-starts and pinch-hit duties once Stephen Vogt returns to the lineup.

Blair was called up from Triple-A Nashville on Tuesday.

After seven years in the Red Sox's organization, Blair made the jump out west this season, splitting time between Double-A Midland and Nashville. His numbers took a nose dive with his move up to Nashville, with his OPS dropping from .898 to .607 between levels. He has some pop, but Blair figures to serve primarily as a bench option moving forward.
