Despite his impressive physical credentials, Mercer wrestled a sparse series of matches, most of which were losses to notable up-and-coming wrestlers including Big E. Langston, Brad Maddox and Erick Rowan.

Mercer participated on August 1 in a losing fatal four-way tag match, teaming with Chad Baxter, against The Ascension (Conor O'Brian and Kenneth Cameron), Jason Jordan and Mike Dalton and Brad Maddox and Rick Victor.

[6] After his wrestling career ended, he had a brief spell in bodybuilding[7] before coming across a man log-lifting at his local gym in Lancaster, struck up a conversation and within two weeks had decided strongman was his sport.

[8][9] In September 2022, Singleton suffered another biceps injury during a training session which put him out of the Giants Live World Tour Finals and Rogue Invitational that were held during October of that year.

Singleton would win two Giants Live shows that year: the Strongman Classic at Royal Albert Hall and World Open in Cardiff.
