Twins move Joe Mauer from catcher to first base following concussion

30 Comments

For the past two months the Twins have repeatedly insisted that they plan to have Joe Mauer remain at catcher next season despite sitting out the final 40 games following a concussion, but today the team announced that Mauer is moving to first base.

Mauer spent 10 seasons at catcher, hitting .323 with an .873 OPS while making six All-Star teams and winning three batting titles, three Gold Glove awards, five Silver Slugger awards, and one MVP. Among all catchers in baseball history through age 30 he ranks sixth in Wins Above Replacement, behind only Johnny Bench, Gary Carter, Ivan Rodriguez, Joe Torre, and Ted Simmons. Mauer was an amazing all-around catcher.

Back in August when Mauer suffered the concussion I wrote a lengthy article breaking down how a position switch would impact his all-around value. The short version is that big batting averages and on-base percentages would continue to make him a very good-hitting first baseman, but his lack of power would keep him from remaining as elite there as he was at catcher. Instead of being a top-three catcher every season, he projected to be in the 5-10 range among first basemen.

However, at some point this issue became less about value and more about health, and given how he struggled with post-concussion symptoms and given how many catchers spent time on the concussion disabled list this season the move makes sense for both Mauer and the Twins. He needs to be healthy and in the lineup, which is far more likely at first base than catcher.

Minnesota will likely turn to Josmil Pinto as their primary catcher following an impressive September debut, with Ryan Doumit and Chris Herrmann also in the mix to catch.

You do know what a Maddux is, right? In case you forgot, it’s a complete game shutout in which the starter throws fewer than 100 pitches. Friend of HBT Jason Lukehart invented that little metric and, because Greg Maddux is my favorite player ever, it’s pretty much my favorite stat ever.

In the Yankees-Red Sox game tonight it was Masahiro Tanaka doing the honors, tossing 97-pitch three-hitter in which he only allowed one runner to reach second base to beat Boston 3-0. He only struck out three but he didn’t walk anyone. He retired the last 14 batters he faced.

Chris Sale was no slouch himself, striking out ten in eight innings. He’s pitched great this year but he’s not getting any help. The Sox have only scored four runs in his five starts. Boston has scored only 13 runs in their last seven games. They’ve been shut out three times in the past seven. They scored more runs than anyone last year, by the way.

The game only took two hours and twenty-one minutes. Or, like, half the time of a Yankees-Red Sox game in the early 2000s. Progress, people. We’re making progress.

Shelby Miller has a tear in his UCL, considering Tommy John surgery

Nick Piecoro of the Arizona Republic reports that Diamondbacks pitcher Shelby Miller has a tear in his ulnar collateral ligament and is considering undergoing Tommy John surgery. Surgery would end Miller’s 2017 season and would cut into a significant portion — if not all — of his 2018 season as well.

Miller sent his MRI results to Dr. Neal ElAttrache and Dr. James Andrews for second and third opinions, respectively. He could choose to rehab his elbow rather than undergo surgery, but that comes with its own set of positives and negatives.

Miller lasted only four-plus innings in his most recent start on Sunday and carries a 4.09 ERA on the season, his second with the Diamondbacks. His time in Arizona has not gone well.
