Mariner fan Derek Zumsteg writes about how baseball and cheating evolved together, covering the quasi-legal to downright dirty. His last chapter makes some solid points about how various cheats (trick pitches, corked bats and spitters) led us to where we are today, and I agree. The earlier chapters are hit-or-miss, but usually quite humorous. A solid 3.5 stars, and a worthy read for baseball fans.
