The Twins played a sloppy three error game today, but on the whole errors haven't been their biggest defensive problem. They have several players that lack range, especially outfielders, and they have played several guys out of position during the course of this season. The team, overall, hasn't been very good defensively. That is an "eyeball evaluation" not based on defensive metrics. With a staff that still consists of many guys who rely heavily on the defense behind them, I am wondering what can be done to improve the defense going forward, looking hard at 2015. Here are some suppositions: Joe Mauer will be the primary first baseman, Brian Dozier will play second, unless Miguel Sano is off-the-charts impressive, Trevor Plouffe will open as the Twins' third baseman, Oswaldo Arcia is the right fielder and Danny Santana will be in the lineup somewhere. Also Kurt Suzuki will be the starting catcher when the spring rolls around. This scenario leaves three positions open and Santana will start at one of them. Where should Santana play and who should fill the other two spots? Here's my take: Santana starts the season as the Twins center fielder, but can be moved out of center by a resurgent Aaron Hicks, or Eddie Rosario or Byron Buxton. Having watched Santana in center for about 50 games, he has rough edges, but has the range and arm to be a quality defender. The decision in center field makes Eduardo Escobar the shortstop. Finally, the Twins have to find a left fielder. Early in the season, I think Jordan Schafer will get a long look in left field. I also believe and hope that both Santana and Plouffe get some reps in left because both could be moved off their positions by phenoms who aren't quite ready at this time. While what I have sketched out doesn't involve wholesale change (or early position shifts), I think it represents some improvement and I think the relative continuity would also help the defense perform better. Here's a thumbnail of each prospective starter: Mauer: has adjusted to first quite well. I think he's already a better-than-average first sacker. Dozier: He's made a few too many errors, but he has made many acrobatic plays. He is a good defender at second, overall handling the double play well. Escobar: Not great range, but good hands and a fine throwing arm. Plouffe: He's made good strides defensively, he'll never have much range and he really doesn't seem to have soft hands, but his reactions are a bit better and he's throwing the ball far better than I ever thought he would. Schafer: The word out of Atlanta was that he was a lousy outfielder despite great speed. Probably true, but he has looked pretty good in left field so far for the Twins (SSS). Santana in center: Again great speed is an equalizer. He takes some bad routes and bad chances, but his speed has bailed him out a few times. Arcia: He is much improved over last year, demonstrating a nice arm . Suzuki: Not a strong arm, but he is reliable and durable. I would rate Dozier as above average, Mauer slightly above average as are Escobar and Plouffe. In the outfield, Arcia is improved but still a work in progress. Santana is probably just a tick or two from being average and I'll rate Schafer as adequate, just because of his tools (arm and speed). I think this defense is good enough. If the Twins acquire an outfielder, he really need to be good in the outfield. The addition of guys like Sano and Buxton might hurt the defense short term, but they too have good tools.
