As first reported by SI.com’s Jon Heyman late Friday night, the Detroit Tigers plan to call up the organization’s top pitching prospect Jacob Turner. The 20 year old was 3-5 with a 3.48ERA in 17 starts for the Double-A Erie SeaWolves. Turner has struck out 90 batters while walking just 32 in 113.2 innings this year. Eastern League batters are hitting just .239 against him. Turner who was 9th overall pick in the 2009 draft went a combined 6-5 with a 3.28ERA between the Low-A Western Michigan Whitecaps and the High-A Lakeland Flying Tigers in 2010. He is considered to be one of the top pitching prospects in all of baseball and was among the key pieces of the Tigers bid to acquire Colorado Rockies pitcher Ubaldo Jimenez at the trading deadline.
