C Brian Harper 1991-1993 .307/.343/.426/.769 109 OPS+ 6.7 WAR
As in the previous decade, Harper might have been overshadowed because his career was split between two arbitrary decade markers. The Twins got some surprising production out of Terry Steinbach late in the decade, but the last three years of Harper’s Twins career was better.
1B Kent Hrbek 1991-1994 .260/.361/.442/.803 116 OPS+ 0 WAR
These were the decline years for Hrbek and still, excluding his final season, he was productive for the Twins. From 1995 to the end of the decade, the Twins searched in vain to fill Hrbek’s “spot” at first base, which may be the best tribute to T-Rex.
2B Chuck Knoblauch 1991-1997 .304/.391/.416/.807 114 OPS+ 37.9 WAR
The MVP of the decade and one of the best players in franchise history.
SS Pat Meares 1993-1998 .265/.301/.381/.682 76 OPS+ 6.0 WAR
Meares gets this sport over two seasons of Gagne at the beginning of the decade and two seasons of Guzman at the end. Meares was a consistent performer and provided decent offensive production considering his solid defense up the middle.
3B Corey Koskie 1998-2000 .298/.388/.495/.833 109 OPS+ 5.1 WAR
Third base was a bit of a revolving door for the Twins until Koskie locked down the job late in the decade. He was probably the team’s best hitter in 1999 and 2000 but did not get much recognition. His defensive reputation as a rookie was poor, but he worked hard and became a very good defensive third baseman as well.
LF Shane Mack 1991-1994 .306/.372/.483/.855 130 OPS+ 17.2 WAR
Mack played right field for the World Series team but was moved primarily to left the following season. The Twins got five prime seasons from Mack, who was not the same player when he returned from Japan.
CF Kirby Puckett 1991-1995 .315/.363/.492/.856 127 OPS+ 19.4 WAR
Was primarily a right fielder in his last couple of seasons, but played more center field in the decade. Puckett, like Hrbek, was in his autumn years. Unlike Hrbek, he was productive right the the end, though the end came more suddenly for Puckett.
RF Matt Lawton 1995-2000 .274/.377/.426/.803 105 OPS+ 9.1 WAR
Lawton took over for Puckett in right field. Though he was up and down, he had some very good seasons and held down the position for the last half of the decade.
DH Chili Davis 1991-1992 .282/.385/.476/.862 136 OPS+ 5.3 WAR
Davis started a revolving door of veteran designated hitters including Dave Winfield and Paul Molitor. Only played with the team for two seasons, but was a huge power threat in the middle of the lineup in a decade in which the team had very few of them.
SP Brad Radke 1995-2000 4.32 ERA 4.39 FIP 1.290 WHIP 114 ERA+ 27.7 WAR
Radke was a very good pitcher for a very bad team for a very long time. The good news for him is that the team’s fortunes would turn for the better in the next decade.
SP Kevin Tapani 1991-1995* 4.12 ERA 3.74 FIP 1.287 WHIP 106 ERA+ 15.6 WAR
Tapani’s name often gets forgotten among the World Series rotation because of Jack Morris and Scott Erickson, but he was not only a better pitcher for the Twins after 1991, he might have been the best pitcher on that team.
SP Scott Erickson 1991-1995* 4.34 ERA 4.14 FIP 1.425 WHIP 102 ERA+ 12.6 WAR
Erickson was a but maddening to follow with some very high highs and low lows throughout the early 90′s.
SP Eric Milton 1998-2000 4.96 ERA 4.61 FIP 1.325 WHIP 101 ERA+ 9.7 WAR
Milton came to the Twins in the Knoblauch trade and had three solid seasons to kick off his career.
CL Rick Aguilera 1991-1999* 3.59 ERA 3.80 FIP 1.183 WHIP 130 ERA+ 12.5 WAR
Held down the closer role for the vast majority of the decade. Aggie was considered one of the best closers in the game for a period.
RP Carl Willis 1991-1995 3.65 ERA 3.08 FIP 1.268 WHIP 120 ERA+ 3.8 WAR
The veteran had his best seasons with the Twins and was a throwback in how versatile he was.
RP Eddie Guardado 1993-2000 5.06 ERA 4.84 FIP 1.456 WHIP 96 ERA+ 4.5 WAR
Guardado makes this list more due to longevity than quality, but towards the end of the decade he improved and was a very good pitcher, foreshadowing his success as a closer in the early 2000′s.
