🏳️ Mark Petronis

Mark Petronis competed in American Endurance Racing in 2017, recording two wins and two podium finishes across two starts in that series. His career spanned seven seasons from 2015 to 2021 with 27 starts across multiple series, though the majority of his results remain unspecified in the record. He has since retired from racing.[1]

Petronis competed at a developing amateur level, with a Racer Rating of 1,146 placing him among drivers working through entry-level competition. His average finishing position of P3.7 across classified starts reflects strong performance in the races he completed, though this figure is weighted heavily by his undefeated record in American Endurance Racing. In head-to-head competition with regular rivals, Petronis showed a clear advantage over drivers at his own level; he finished ahead of John Gatzemeyer in 11 of 12 shared races and Keith Workman in all 8 they contested together. He also notched five wins against Doug Winston, a semi-professional driver rated significantly higher. Against stronger company, however, the pattern reversed; Adrian Wlostowski, a professional-level competitor and American Endurance Racing Class 3 champion, finished ahead of Petronis in five of their six meetings despite Petronis taking one race.
