ATLANTA -- Marlins pitching prospect Tyler Kolek, the No. 2 overall pick in the 2014 First-Year Player Draft, is on a no-throw status for about a week due to lower back discomfort.
The 6-foot-5, 260-pounder faced just four batters on Wednesday night for the Gulf Coast League Marlins. He complained of pain in his lower back on the right side and was lifted after one-third of an inning.
An X-ray was taken, and after Kolek was examined, it was recommended that he not throw for a week. At that point, he will be re-evaluated.
The 18-year-old from Shephard, Texas, was making his fifth start since joining the Gulf Coast League team. He is 0-2 with a 4.50 ERA, with 10 strikeouts in 10 innings.
Wednesday's game was suspended due to inclement weather.
