Every MLB fan thinks they know the game better than their rival. Casino.ca put that confidence to the test with a 5,000-fan survey built around a 20-question baseball knowledge quiz.

New York came out on top, with Mets and Yankees fans tying for No. 1 at 18 out of 20. Both fanbases actually outperformed their own confidence levels, with Mets fans rating themselves 7 out of 10 and Yankees fans just 6 out of 10.

At the bottom, Diamondbacks and Rangers fans tied for last with 10 out of 20. Texas had the funniest miss of the survey, rating itself 8 out of 10 despite finishing at the bottom.

California was all over the board. Angels fans ranked highest in the state, tying for second overall at 17 out of 20 with an 8 out of 10 self-rating. Dodgers fans finished No. 4 at 15 out of 20.

The Athletics and Padres tied for No. 7 with 12 out of 20, while Giants fans ranked lowest among California teams at No. 8 with 11 out of 20.
