Kolek is in the final stages of rehab from his Tommy John surgery, and is hoping to get back on the mound in May, The Miami Herald reports. Still only 21, the second overall pick in the 2014 draft has had a brutal start to his pro career, showing poor control and command in the low minors for two seasons before blowing out his elbow last spring. Kolek still rates as one of the top prospects in a talent-starved Marlins system, but in most dynasty leagues there's little reason to use a roster spot on him until he shows any kind of progress.
Kolek underwent Tommy John surgery Wednesday, Jonathan Mayo of MLB.com reports. The Marlins have not confirmed the report, but Kolek felt soreness in his elbow at the end of spring training, and after receiving several opinions, the decision was apparently made to send him under the knife. Kolek was taken second overall in the 2014 draft and is one of the Marlins' top prospects, but he will now be forced to spend this season recovering and rehabbing, with an eye toward getting back on the mound at some point roughly 12 months down the road.
Marlins pitching prospect Tyler Kolek, the second-overall pick in the 2014 draft, is showing promise as he maneuvers through the Class A ranks for the Greensboro Grasshoppers. Kolek, who is rated as the Marlins' top prospect by MLB.com, has an impressive 3.67 ERA over his last six starts, despite having just a 1-4 record over that span to show for it. In his last 27 innings of work, Kolek has limited batters to a .248 average at the plate. Overall, Kolek has a 4-6 record this season with a 4.44 ERA and 49 strikeouts and 36 walks over 75 innings.
