Hacker spent the rest of 2006 and all of 2007 rehabbing and learning from Coach Bloomfield and Coach Shuler. Hacker’s first year back from his injury was a good one as he took his team deep into the playoffs beating the number one seed, Fresno city college.

In 2010, Hacker signed as a free-agent with the Boston Red Sox. He spent two seasons with the minor league club and the injury bug came again. After a surgery in late 2011, he spent his last season in the United League playing for Former Cleveland Indians Manager and Big Leaguer, Doc Edwards. In 2013, Hacker started coaching and mentoring the younger generation. Players like Jack Wolger (CAL), Tiegan Jones (Fresno State), Tyler Schimpf (San Francisco Giants) were a few of his clients. In 2016 and 2017, Hacker was the Varsity Pitching Coach for Folsom High School. From 2017 to 2019, he was the Head Assistant and Pitching Coach at Cosumnes River College. Coach Hacker then went on to work with UC Davis, where he is currently the Pitching Coach. 

“I have spent my entire life around the game of baseball. I have been truly blessed to have learned the game, and it’s life lessons, from some outstanding coaches. I’ve had coaches in the Big Leagues, like Doc Edwards, Tom Goodwin, and George Lombard, and college coaches, Tony Bloomfield and Jno Shuler, that I’ve watched and learned from over the years. The coaches in my life had so much influence on who I am as a person now and I am passionate about passing that knowledge along to the next generation.” - Coach Mike Hacker
