Former Madison Central High standout Spencer Turnbull, trying to make a case for a spot on Detroit’s 40-man roster, is having mixed results in the Arizona Fall League. The right-hander, who would be eligible for next month’s Rule 5 draft if not protected, is 2-2 with a 3.74 ERA in six starts for Mesa. He worked 3 2/3 innings on Tuesday, yielding three runs on six hits and two walks while taking the loss. A 2014 second-round pick out of Alabama, Turnbull has endured two straight injury-plagued seasons (shoulder, elbow). He was 7-3, 3.05 at Class A Lakeland in 2017, then went 0-3, 6.20 in six Double-A starts at Erie. MLB Pipeline rates Turnbull as the No. 28 prospect in the Tigers’ system. Reports say he has big league stuff — he just needs to stay healthy. P.S. Meanwhile, down in Mexico, David Goforth is hoping to catch someone’s attention with his showing in the Mexican Pacific League. A minor league free agent, the Neshoba Central High and Ole Miss alum has a 1.96 ERA in 16 appearances for Culiacan, with a win and two saves. Despite solid numbers in Triple-A in 2017, Goforth, 29, only got one big league appearance with Milwaukee. He has pitched in 31 MLB games overall – all for the Brewers — since 2015. In 2014, with Huntsville in the Southern League, he put up 27 saves.
