The Detroit Tigers are already seeing positive results from their new pitching coach Chris Bosio
McCoskey is calling it the “Bosio-effect”. Bosio used a new drill with Shane Greene and the results showed. Greene put up a fourth inning of 11 pitches, four of them swinging strikes. While Bosio is in his first year as the Detroit Tigers pitching coach. He was a factor in Mike Fiers decision to sign with the team.
Fiers was coached by Bosio when he was playing for the Milwaukee Brewer. Under Bosio, Fiers went 8-0 with a 1.10 ERA. Eventually, Fiers went to the Astros while Bosio made his way to the Cubs. The Cubs, of course, won their first World Series in 2016, with Bosio at the helm of the pitching staff.
The Cubs fired Bosio in 2017 and almost immediately the Tigers brought him in to improve the pitching staff. The Tigers have had plenty of well-known issues with the bullpen in past seasons. With how hands-on Bosio is, the problems that have plagued the bullpen in the past might disappear.
McCosky points out another positive example of the Tigers pitching staff with Bosio. Matt Boyd. Boyd had a rocky start in Friday’s game giving up two home runs. However, he had a conversation with the Tigers pitching coach in-between innings and went on to shut down eight of the next nine batters he faced.
Katie Strang, of the Athletic, recently did a Q&A with Tigers pitcher Daniel Norris. Norris was throwing balls higher in the strike zone. Bosio told him to adjust his cap and that little trick helped Norris throw balls lower in the strike zone. The article is behind a paywall, but a subscription to The Athletic is worth it.
Tigers ace Micheal Fulmer also expressed excitement about working with Bosio. The Tigers may be rebuilding, but both first-year skipper Ron Gardenhire and Chris Bosio are taking hands-on approaches. These approaches are already making positive impacts on player performance.
