Going through the postion players, position by position (and counting Arcia as a RF), the Twins are getting less than expected performance from 2B, LF, CF, RF, and DH. I would say they are near expectations for 3B, C, and 1B, and have exceeded (low) expectations for SS. Individually, Mauer and Morneau are performing "well", but unevenly--Morneau hasn't hit with power and Mauer has been uncharacteristically streaky and strikeout prone. They both have been in the lineup more than could be expected and they both are playing well defensively. Given the team's low slugging and batting average, it is surprising they've scored as many runs as they have. I would argue that Plouffe has been average for a regular at the hot corner, but I suppose that is picking nits.
