Toshihiro Deki is a semi-professional driver, rated 3,134. This places him in the middle of paid club and regional racing; he races against professionals but typically finishes behind them rather than competing for wins.[1]
Deki's sole recorded season came in 2009, when he started 13 races in the Star Mazda Championship for Juncos Racing and Goshen Motorsports. He did not score a podium finish and averaged P18.5 across classified starts. The field included several established professionals: Adam Christodoulou, the series champion that year, and Conor Daly, who would win the championship the following season. Against this calibre of opposition, Deki was outmatched consistently, finishing ahead of Christodoulou once in thirteen races and behind Daly twelve times in thirteen. He managed occasional competitive results against less experienced drivers, bettering Rusty Mitchell five times across their thirteen shared races, but these isolated instances did not translate into a pattern of success. Deki's best results came against rivals ranked in the 4,300 to 4,600 band; he could not sustain performance against the championship contenders who populated the grid.
Since his single season in 2009, Deki has not raced competitively. He has been retired from motorsport for fifteen years.
