Raymond Francis Oyler (August 4, 1937 – January 26, 1981) was an American baseball player, a major league shortstop for the Detroit Tigers (1965–1968), Seattle Pilots (1969), and California Angels (1970).

Oyler is noteworthy for having had the lowest career batting average of any position player (with at least a thousand at-bats) in modern baseball history.

Also, as an everyday player in 1967, Oyler increased his batting average to .207, the only year in which he hit above .200, along with a home run, two triples, 14 doubles and 29 RBI.

Oyler's batting average had dropped to .135, and Smith had four quality outfielders in Willie Horton, Jim Northrup, Al Kaline, and Mickey Stanley that he wanted in the lineup for every World Series game.

Oyler did not have an official at bat in the 1968 World Series, but he did appear in all four Detroit victories as a defensive replacement and had a sacrifice bunt.

[7] Stanley returned to play 59 games at shortstop the next year, while Oyler was allowed to be drafted by the expansion Seattle Pilots.

[9] Grabbing onto the popularity of the late 1960s Laugh-In show's "Sock it to Me" catchphrase, the fan club was called the Ray Oyler "S.O.C.

In Ball Four, Seattle teammate Jim Bouton wrote that Oyler's nickname was "Oil Can Harry" because "he always looks as though he had just changed a set of rings."

Oyler was sold by Oakland in April 1970 and played his final 24 games with the California Angels, with a perfect fielding percentage and a .083 average at the plate.
