Steven Ralph Arlin (September 25, 1945 – August 17, 2016) was an American pitcher in Major League Baseball who played for the San Diego Padres and Cleveland Indians for six seasons.

Arlin also pitched in the Phillies’ farm system in 1968 before being selected by the San Diego Padres in the expansion draft.

In 1973 Arlin recorded a personal best 11 victories against 14 losses, but with a 5.10 ERA—nearly a run and a half above his career ERA to that point.

The Indians completed the trade a week later by sending pitchers Brent Strom and Terry Ley to the Padres.

During his Major League career, Arlin won 34 games (11 of which were shutouts) while losing 67, with 463 strikeouts and a 4.33 earned run average in 7882⁄3 innings pitched.
