Fimple once again was the primary catcher; among the pitchers he caught were John Franco, Brian Holton, and Orel Hershiser.

He got one at bat as a late inning defensive replacement for Steve Yeager in an 8-0 loss versus the San Francisco Giants.

Fimple would play in both games of the double header the next day, and got his first major league hit, a single to left field off Giants starter Fred Breining.

At the conclusion of the 1984 season, Fimple underwent surgery for repair damage he suffered to his ulnar nerve in his elbow.

The trade would have sent Fimple, power hitting prospect Ralph Bryant, along with pitchers Bob Welch and Tom Niedenfuer to the Philadelphia Phillies for star third baseman Mike Schmidt.

The California Angels signed Fimple as a free agent in 1987 and assigned him to their Triple-A club, the Edmonton Trappers.

While Fimple played in a handful of games for the Angels that season, serving as a backup to Bob Boone and Butch Wynegar, he continued to struggle to find his old form.
