Peterson appeared in 13 games playing for the Cleveland Indians and Texas Rangers, throwing 62 innings and finishing with a 1-3 record along with an earned run average of 5.08.
In just the previous year he went 14-8 for the Indians, with a couple of shutouts and a 3.94 ERA, so the rapid decline was a surprise for the man who was also a former 20-game winner, something he did while with the New York Yankees in 1970.
While with the Yanks, he posted three straight seasons of sub-3.00 ERA’s between 1968-1970: 2.63, 2.55 and 2.90, while posting win totals of 12, 17 and 20.
By the time he retired after the 1976 season, he ended up with a career record of 133-131, with a nice 3.30 ERA and 20 shutouts over 355 appearances and 2218.1 innings pitched.
