The Mariners introduced a nautically themed bullpen car called the "Tugboat" for the 1982 season. It got off to a rocky start for the home opener when Caudill stole the keys during pregame festivities, leaving the Tugboat stranded on the left-field line and delaying the start of the game. On another occasion, when brought in to pitch in a one-sided game, Caudill appeared from the bullpen sporting a half-shaved beard. He acquired the nickname "the Inspector" after inspecting the Mariners bats for unused hits and discarding those he deemed empty. The team began playing the Pink Panther Theme over the Kingdome loudspeakers when he was summoned from the Mariners' bullpen. Despite his antics, Caudill emerged as one of the American League's top relievers his first season in Seattle. He felt snubbed when All-Star manager Billy Martin of Oakland left him off the AL squad, which had eight His record stood with a 1.95 ERA and a team record seventeen saves when selections For the season, he went with a 2.35 ERA, 26 saves, and 111 strikeouts. Caudill's 26 saves in 1983 mirrored his previous season's production, however, his record dipped while his ERA ballooned to 4.71. Following the season in November, he and Darrel Akerfelds were dealt to the Oakland Athletics for Dave Beard and
Oakland A's
Caudill returned to form with the A's in the first half of the 1984 season. His record stood with a 1.97 ERA and eighteen saves when AL manager Joe Altobelli of Baltimore named him to his AL squad. With the NL leading Caudill was brought in to pitch the seventh inning, and he struck out all three batters he faced. From there, things seemed to turn around on Caudill. He went in the second half with a 3.60 ERA and blew four saves. He finished 1984 with a career-high 36 saves, which was second in the American League only to the 44 of Kansas City Royals' Dan Quisenberry. Following the season, he was traded to the Toronto Blue Jays for Dave Collins and Alfredo Griffin.
Caudill was manager Bobby Cox's top closer upon his arrival in Toronto, but lost his job to Tom Henke by the end of the 1985 season. The formula worked as the Jays won the American League East by two games over the Yankees. The Jays jumped to a series lead in the American League Championship Series against the Kansas City Royals, however, was the first post-season that the championship series was expanded to seven games. KC came back to win the series in seven games ; Caudill did not make an appearance. A shoulder injury limited Caudill to forty appearances in 1986. He went with a 6.19 ERA and just two saves as the Blue Jays fell and fourth place in their division under new manager Jimy Williams. He was released during spring training the following season, and shortly afterwards, he signed with the A's.
Final season
Trying to rebound from a subpar season with Toronto in 1986, Caudill began the 1987 season with Oakland's triple A affiliate, the Tacoma Tigers of the Pacific Coast League. He pitched effectively enough to earn a call to the majors; however, after just a month with the A's, he suffered a broken hand after punching a man who was reportedly trying to accost his wife in a hotel parking lot in 1987. It effectively ended his big league career at age 30. Caudill currently coaches and works for his former agent, Scott Boras, who is also a former minor league teammate and close friend.
