Ian Kennedy had an interesting up-and-down career in Major League Baseball, but by far the best season he ever had was in 2011.  That year, Kennedy went 21 and 4 with a 2.88 Earned Run Average while finishing fourth in Cy Young voting, and driving the Diamondbacks to a division title.  He would secure 15 Wins the next year, but was traded to San Diego during the following season.

Kennedy returned in 2022, though had an awful year with a negative bWAR and an ERA over five.  He left again, this time for Texas.

His record with Arizona was 48-34 with 661 Strikeouts.
