Overall,. he went 10–10 with a 5.19 ERA. April 23, 1994 marked the date of Elliott's major league debut. It would end up being his only big league start. Coincidentally, the opposing team he was facing was the team that originally drafted him, the Phillies. Even more coincidentally, he was facing the pitcher he was traded for on May 28, 1992, Ben Rivera. Neither pitcher fared very well in that game, with Elliott lasting only 2 innings, giving up two earned runs, four hits and two walks. Rivera lasted four innings, allowing seven hits, five earned runs and four walks. In the end, the Padres won the game 8–2. After being converted to a reliever, Elliott did much better, finishing the season with a 3.27 ERA in 30 total games, with his ERA as a reliever being 2.97.

That would be the final game of his big league career. In the minors that season, he spent seven games with the Las Vegas Stars, posting a 4.50 ERA in eight innings. Even though his big league career was over, he stuck around in the minors for a while. In 1996, he was back in the Phillies organization, pitching for the Scranton/Wilkes-Barre Red Barons. He went 5–11 with a 4.79 ERA as a starter. He did not play affiliated baseball in 1997, and in 1998 he played his final season, this time in the Texas Rangers organization.

Technique
One day during the 1994 season, Elliott's teammate, Trevor Hoffman asked Elliott how he threw his change-up. Elliott showed Hoffman his usual grip of pinching his index finger and thumb together at the point of release. Hoffman perfected this pitch and credits this usual grip as helping him master one of the nastiest change-ups in the major leagues. Elliott is now teaching his change-up to high school pitchers as he is currently the assistant head baseball coach at Deer Park High School in the Deer Park Independent School District. Elliott was a high school teammate of former Philadelphia Eagles defensive linemanTommy Jeter and New York Yankee's pitcher Andy Pettitte. During Elliott's playing days he was romantically linked to several Hollywood movie actresses and once auditioned for a small role on the soap opera, 'Days of Our Live''s.
