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.

Update (7:00 PM ET): The MLBPA announces that the deadline has been extended 24 hours while MLB and NPB continue to negotiate a new agreement for the posting system. The new deadline is 8 PM ET on Tuesday.

Last Thursday, we learned that the MLBPA was challenging the Nippon Professional Baseball posting system, delaying Japanese superstar Shohei Ohtani’s move to Major League Baseball. The latest collective bargaining agreement removed a lot of the incentive for players to come to the U.S. by capping pay. Ohtani, for example, can only receive a signing bonus between $300,000 and $3.53 million while his team — the Nippon Ham Fighters — would receive $20 million for posting him.

Jon Morosi reports that the deadline for this issue to be resolved is 8 PM ET on Monday evening. He notes that key NPB officials have worked through the night in Japan to try to reach a resolution. It is possible that even if no agreement is reached, the deadline could be pushed further back.

Ohtani, 23, has become a heralded hitter and pitcher in Japan. At the plate over his five-year career, he has compiled a .286/.358/.500 triple-slash line with 48 home runs and 166 RBI in 1,170 plate appearances. On the mound, he has a 2.52 ERA with a 624/200 K/BB ratio across 543 innings.
