As a 1966 Yankee rookie with an average fastball and curve, but with great control and finesse, Peterson went 12-11. By 1970 he had improved to 20-11. Peterson’s pitching career plateaued, but he and teammate Mike Kekich made headlines in 1973 when the two traded wives and families. The awkward situation prompted the Yankees to send Kekich to the Indians. By the time Peterson was exiled to Cleveland with three other pitchers the following year, Kekich was no longer there.
