During Potato Pete's return, he won 16 races in a row to tie the other pierogies, while Cheese Chester made a "rehab start" during the Panera Bread Great American Bagel Race during the August 28, 2014 game between the Altoona Curve (the Pirates Double-A affiliate) and the Richmond Flying Squirrels, competing against the bagels Blueberry Bob, Asiago Allie, and Cinnamon Crunch Cindy. (Coincidentally, Pirates pitcher Charlie Morton was himself making a rehab start in the game.) It was considered the first "MLB Mascot Rehabilitation Assignment". Cheese Chester then spent the next two days confronting Potato Pete at PNC Park until the two agreed that whoever won a one-on-one race after the Pirates game against the Cincinnati Reds on August 30, the winner would race with the rest of the pierogies the rest of the season while the loser would be out for the season. Cheese Chester won his spot back after Potato Pete built a sizable lead but tripped after taunting Cheese Chester, allowing Cheese Chester to win the one-on-one race and return to the season-long competition.
