Bold = Player new to Minnesota in 1981
SP Pete Redfern 9-8 4.07 ERA 97 ERA+ 1.36 WHIP 3.76 FIP -0.2 PW 8 WS 2.9 WARP3
The roller coaster that was Pete Redfern’s career leveled off a bit in 1981. 23 of his 24 pitching appearances came as a starter, the most starts for him since 1977. He pitched more innings than in any other year of his career (141.2) and had more complete games (3) than any other year in his career. When Koosman faltered early in the season, Redfern was considered the team’s number one starter.
SP Albert Williams 6-10 4.08 ERA 97 ERA+ 1.41 WHIP 3.60 FIP -0.1 PW 7 WS 3.1 WARP3
Williams was originally signed out of Nicaragua by the Pittsburgh. After a few years in the Pirates’ system, Williams became a free agent. The Twins picked him up before the 1980 season and were pleased with the success he had in limited action. Williams took more of a full-time role in 1981 and had mixed success, though the overall feeling was still positive.
SP Fernando Arroyo 7-10 3.93 ERA 101 ERA+ 1.39 WHIP 4.02 FIP -0.1 PW 6 WS 2.5 WARP3
Arroyo was a light-throwing pitcher who relied on finesse to make it to the major league level. His most significant brush with fame might be the fact that he replaced an injured Mark Fidrych in the Detroit rotation in 1977. He went on to lose 18 games that year. He was traded to the Twins in December of 1979. Though he only had limited success with the Twins, 1981 might have been his most effective year as a pitcher.
SP Jerry Koosman 3-9 4.20 ERA 94 ERA+ 1.40 WHIP 3.62 FIP -0.3 PW 5 WS 1.7 WARP3
Koosman’s “homecoming” to the Twins was a smashing success for two seasons, but quickly fizzled out in 1981. He got off to a 1-6 start an never recovered. By the end of the season, Koosman was making his appearances out of the bullpen. Koosman was traded to the White Sox at the deadline for a couple of minor league players, a PTBNL, and cash. He did go on to have some success north of the age of 40 with the Sox and later the Phillies before he retired in 1985.
SP Roger Erickson 3-8 3.84 ERA 103 ERA+ 1.36 WHIP 3.65 FIP -0.1 PW 4 WS 1.4 WARP3
For the second straight seasons Erickson had a terrible won-loss record, but his underlying statistics indicate that he really didn’t pitch all that poorly. Erickson was rumored to be part of a trade for most of the offseason, and an win at arbitration made a deal a near-certainty. He was sent to the Yankees along with Roy Smalley in May of 1982.
CL Doug Corbett 2-6 2.57 ERA 154 ERA+ 1.30 WHIP 3.14 FIP 1.7 PW 12 WS 4.5 WARP3
Just as in 1980, Doug Corbett carried the relief load almost on his own. He was one of the few bright spots on the team, and the only Twin represented at the All Star Game. After the season, Corbett’s agent suggested that he exercise his right to go to arbitration to increase his salary. Corbett decided that it was a matter of his word, and that he had told the Twins he would agree to play for two years and be paid $500,000. His loyalty was rewarded with a trade to the California Angels as part of a salary dump in May of 1982. Corbett had some solid seasons in Anaheim, and even made an appearance in the 1986 ALCS. He finished his career with a short stint in Baltimore in 1987. Corbett was only with the Twins for parts of three seasons, but was dominant. He would be the last effective closer for the Twins until Jeff Reardon came in the late ’80s.
RP Don Cooper 1-5 4.30 ERA 92 ERA+ 1.59 WHIP 5.16 FIP -0.3 PW 2 WS 0.6 WARP3
RP John Verhoeven 0-0 3.98 ERA 99 ERA+ 1.37 WHIP 3.91 FIP 0.0 PW 2 WS 0.7 WARP3
As mentioned, there wasn’t much to the Twins’ bullpen behind Corbett. Verhoeven and rookie Don Cooper were really the only other options. Verhoeven did not see another major league game after 1981, Cooper saw just 17 more spread out between 1982 and 1985.
