After being released from Detroit before the 2013 season, Boesch spent most of his remaining career playing for the Minor League teams of the New York Yankees, Los Angeles Angels, and Cincinnati Reds until retiring before the 2017 season when no team signed him from free agency.

[3] He won the World Wood Bat Championship as a member of Team Baseball America, was selected Best Hitter at the Area Code Games, Best Power Hitter at the Team One Nationals and won the Daily News Invitational Home Run Derby.

[5][6] Following his junior season, Boesch elected to participate in the 2006 Major League Baseball Draft and was picked in the third round by the Detroit Tigers.

With the Double-A Erie SeaWolves, Boesch led the Eastern League in home runs (28) and won the MILB Round Trippers Award for leading all of AA in home runs, en route to his selection by Baseball America as Best Power Prospect AA.

The Tigers called up Boesch from the Toledo Mud Hens to replace the injured Carlos Guillén on April 23, 2010.

But after July, his playing time was reduced and Boesch completed his season with a .240 batting average, 12 home runs and 54 RBIs over 132 game appearances.

On July 19th, the Yankees released Boesch outright while he was on rehab assignment for the RailRiders for a slight muscle tear, this enabled them to make room on the roster to replace the injured All-Star shortstop Derek Jeter with another infielder.

Boesch, a free agent going into the 2013 off season, played for the Escondigo Leones of the Dominican Republic Winter League where among other things he worked on sharpening his eye.

[15] On November 26, 2014, Boesch signed a minor league deal with the Cincinnati Reds and was assigned to the Louisville Bats.

[17] Boesch announced his retirement from professional baseball the following spring, on April 11, 2017, after no other team expressed interest in signing him.

[18] As of 2024, Boesch has returned home to LA and has endeavored to launch a career in country music, occasionally playing at local cafe's and bars in the Los Angeles area.
