Tim Williams of Pirates Prospects is reporting that Mitch Keller has been promoted to the Bradenton Marauders.
Keller entered 2016 in his first full season with the West Virginia Power. The 20-year-old right-hander has put up phenomenal numbers, posting a 2.46 ERA with a 9.5 K/9 and a South Atlantic League best 0.92 WHIP in 23 starts. A few weeks ago, Keller was voted the best pitcher in the SAL for 2016. He’s quickly emerged as one of the top prospects in the Pirates system, ranking #5 according to MLB Pipeline.
