Marsee will undergo a UCL repair with an internal brace on his left elbow Monday, Christina De Nicola of MLB.com reports.
Analysis:Marsee played through elbow soreness down the stretch of the regular season, and surgery was recommended following a visit with Dr. Keith Meister. He is expected to be ready to play in games again in six months, which puts his availability for Opening Day in doubt. Marsee slashed .231/.348/.359 with 11 home runs and 23 stolen bases this season for Miami.
