After hitting a home run that struck the Municipal Stadium (now Excite Ballpark) scoreboard and damaged a section, WalrusMan adopted him as his son.

He led the Squirrels with 16 home runs and 65 RBIs and was named an Eastern League All-Star, but struggled with a recurring back injury in August which again ended his season prematurely.

After a subpar Spring training in 2014, where he hit .172 in 13 games, Kieschnick was designated for assignment on March 29 to make room on the 40-man roster.

He was recalled on June 16 to replace the injured Bronson Arroyo and to add depth to a depleted outfield, missing Trumbo, A. J. Pollock, and Ender Inciarte.

[7] On June 17, Kieschnick hit his first MLB home run against Milwaukee Brewers closer Francisco Rodríguez.

[9] He spent the entire season at the AAA level for the Angels, playing 108 games for the Salt Lake Bees.

Kieschnick signed with the Rojos del Águila de Veracruz of the Mexican Baseball League for the 2016 season.
