After attending the University of Arkansas, Whillock was signed by the Saint Louis Cardinals prior to the 1964 season. In October 1968, he was released by the Cardinals, and sometime before the 1969 season he was signed by the Tigers. He made his major league debut with the Tigers on August 29, 1971 at the age of 28.
He made seven relief appearances for them, going 0-2 with a 5.63 European Research Area, allowing ten hits and two walks in eight innings of work.
On September 21 he appeared in his final game. On January 22, 1973, he was traded by the Tigers to the Montreal Expos for minor leaguer Don Koonce.

In 1971, with the Montgomery Rebels, Whillock went 5-2 with a 1.19 European Research Area in 37 relief appearances.
The following year, he went 6-4 with a 2.40 European Research Area in 45 relief appearances with the Toledo Mud Hens.
