Chris Bosio’s most immediate and most daunting challenge with the Tigers will be salvaging a failed investment: Jordan Zimmermann. Detroit’s new pitching coach may be just the man for the job. Bosio is credited with helping Jake Arrieta turn his career around when the Cubs acquired him from the Orioles in 2013. In two years, Arrieta went from a castoff to a Cy Young. That kind of arc isn’t in the cards for Zimmermann, but Bosio sees a lot of similarities between the two pitchers. “Jake Arrieta reminds me a lot of a guy that I saw when he was pitching with a Division-3 program in Wisconsin — Jordan Zimmermann,” Bosio said in his introductory conference call with Detroit-area reporters. Bosio, who spent six years as the Cubs pitching coach, also played a key role in the rise of Kyle Hendricks from eighth-round draft pick to ERA champ. He got the best out of Hendricks and Arrieta, he said, by developing personal relationships with them.
