Twins Video
Defensive metrics have improved greatly over the last decade. With Statcast tracking every batted ball, the amount of information available to fans is at an all-time high. One metric the Society for American Baseball Research (SABR) developed is the SABR Defensive Index (SDI).
According to SABR's website, the SDI "draws on and aggregates two types of existing defensive metrics: those derived from batted ball location-based data and those collected from play-by-play accounts." Since 2013, SDI has been used as part of the process for selecting Gold Glove winners. The rankings below are the final rankings for the 2024 season.
Pitcher (AL Ranking): Bailey Ober 2.2 SDI (t-8th), Pablo López -1.4 SDI (27th)
Minnesota had two Gold Glove finalists last season, López and Sonny Gray, but both players lost to former Twins pitcher José Berríos. López took a step back defensively this year, as only seven AL pitchers finished with a lower SDI total. Ober moved into the top 10 among AL pitchers and was close to moving into the top five. He is a large man on the mound, and he made solid improvements regarding his fielding, partially by understanding better how to use his length in covering the area around and in front of the mound. Joe Ryan ranked well according to SDI earlier in the year, but fell off the rankings due to his injury.
Catcher (AL Ranking): Christian Vázquez 4.0 SDI (7th), Ryan Jeffers -4.7 SDI (15th)
Vázquez had been in the top four at the last SDI update in August. but fell off in the season’s final weeks. He still finished in the top seven due to good framing (84th percentile) and Fielding Run Value (78th percentile). Jeffers continues to struggle defensively with his pitch framing, which is only part of the problem. Four AL catchers finished with a lower SDI total than Jeffers. Both catchers are projected to be back next season, so the Twins will need to get more value from Jeffers.
First Base (AL Ranking): Carlos Santana 9.5 SDI (1st)
Santana earned the Gold Glove at first base and was one of the top defenders in the entire AL. His 9.5 SDI ranked eighth among all AL defenders, and only two infielders had a higher SDI. Santana earned a chance to earn the Platinum Glove, but will likely finish behind Cleveland’s Andrés Giménez, who had the league’s highest SDI total. Still, Santana had an elite season at first base. Minnesota will likely get less value from first base, even if the team re-signs him, because of his age.
Second Base (AL Ranking): No Twins Qualified
There were two dominant second basemen in the AL this season and a lot of mediocrity. Giménez and Marcus Semien compiled two of the AL’s top SDI totals. Minnesota had three players play 40 games or more at second, including Edouard Julien, Kyle Farmer, and Willi Castro. Julien had a -4 OAA, Farmer posted a 3 OAA, and Castro finished with a 0 OAA. With Farmer departing, second base is a clear spot for the Twins to improve for 2025. Brooks Lee might be the one to step into the void.
Third Base (AL Ranking): No Twins Qualified
Minnesota had five players log over 140 innings at third base this season. José Miranda led the way with 73 games started, but he produced -7 OAA. Royce Lewis was the team’s Opening Day starter at the hot corner but got injured in the team’s first game. He missed a chunk of the season and ended up 2 OAA despite some throwing issues in the middle of the season. It will be interesting to see where Minnesota goes with third base next season. Minnesota’s best infield alignment might be Lee at third, Carlos Correa at shortstop, and Lewis at second base, but Lewis didn't like playing the keystone when asked to slide there in the summer.
Shortstop (AL Ranking): Willi Castro -5.2 SDI (13th)
Correa ranked in the top 10 among AL shortstops earlier in the season, but his second-half injury kept him off the final leaderboard. Castro is slightly overmatched at shortstop but was asked to fill in when Correa hit the IL. Somewhat strangely, he produced 3 OAA at short, his highest total at any position. Paul DeJong (-8.8 SDI) is the lone AL shortstop with a lower SDI total than Castro. An entire season of a healthy Correa at shortstop can alter the team’s entire defensive outlook for 2025.
Left Field (AL Ranking): No Twins Players Qualified
The Twins used eight players in left field this season, and six players accumulated over 150 innings. Minnesota will likely continue to rotate players through the position in 2025. Trevor Larnach is projected to be the team’s starter, but he was limited at that position this season due to an injury relegating him to DH duties in the second half. Minnesota also has an opportunity to bring in a right-handed corner outfielder to pair with the team’s left-handed sluggers.
Center Field (AL Ranking): No Twins Players Qualified
Byron Buxton logged over 760 innings in center field for the first time since 2017, when he was the AL’s Platinum Glove winner. In 2024, he was credited with 3 OAA and a 4 Fielding Run Value, ranking in the 74th percentile or higher. Buxton is also entering the offseason healthy for the first time in six seasons, which could help him build the positives from last year. Minnesota will still likely need a backup plan if/when Buxton is unavailable. DaShawn Keirsey Jr. might be in the running for a fourth outfielder role, unless the Twins want to look outside the organization.
Right Field (AL Ranking): Max Kepler 0.9 SDI (4th)
Kepler has been known for his defense throughout his Twins tenure, and the team will suffer a drop-off with his replacement next season. Matt Wallner is expected to be the team’s Opening Day starter, and posted a -1 OAA in right field. His arm should be a huge asset, and he's more athletic than his size implies, but there remain rough edges to sand off. As with left field, the team may use internal right-handed hitters to replace Wallner in the lineup when there is a strong lefty on the mound.
There will be some defensive changes for next season, with two of the team’s best defenders expected to leave in free agency. Minnesota has some internal options to fill those spots on the roster, but they would likely come with worse defensive totals. This is a critical area for the front office to address this winter.
