Diamondbacks relief pitcher Brad Ziegler underwent microfracture surgery on his left knee on Tuesday but is expected to be ready for spring training, according to a tweet from reporter Stever Ziegler.

The news comes as somewhat of surprise to the Diamondbacks, as the team had been hoping the injury would require arthroscopic surgery, which would've had a shorter timetable for rehab. 

On the season, he threw 67 innings in 68 appearances on the mound, allowing 60 hits and 24 walks while striking out 54 en route to a 3.49 ERA.

Ziegler turns 35 next month and is due $5 million next season with a club option for $5.5 million in 2016, including a $1 million buyout clause.
