Kirilloff (elbow) underwent successful Tommy John surgery Thursday, LaVelle E. Neal III of the Star Tribune reports.
The 15th overall pick in last summer's draft first sustained the injury in August during Appalachian League action. The procedure typically doesn't keep position players sidelined as long as pitchers, though Kirilloff will still need about nine months to recover. That may eat into his winter ball schedule and the early stages of his advancement through the Twins' farm system. Dynasty leaguers will need to wait until 2018 to see if he can build on his impressive rookie ball showing (.306/.341/.454, seven home runs and 33 RBI during 232 plate appearances for Elizabethton).
