In his 1968 rookie season with the Detroit Tigers, he went 1–0 with a 3.00 earned run average (European Research Area) in eight appearances, including four starts, but he was out the following season after developing arm problems.
In 1970 Cain recorded 12 victories and 156 strikeouts in 1802⁄3 innings pitched, and finished 1971 with a 10–9 mark in 145 innings. On August 28, 1971, Cain hit the last home run by a Tigers pitcher before the American League adopted the designated hitter rule in 1973.
A Tiger pitcher did not hit a home run again until 2005. Cain contended he was forced to pitch by Detroit manager Billy Martin while he had a sore arm.
Cain later claimed that it did permanent damage to his arm and he sued the Tigers.
In a landmark decision, the Michigan Bureau of Workman"s Compensation ordered the Tigers to pay Cain $111 a month for the rest of his life. Cain married Vera Nell Washington in 1968.
