Jack Wilson, 31, is an exemplary defensive shortstop. He is very clearly comfortable at his position, and according to the numbers we have, he's probably worth 5 or 10 runs above average in the field. He doesn't, however, have much of a bat, with a career wOBA of .298 and a ZiPS projection of .294.
Jack Hannahan, 29, is an examplary defensive third baseman. He is very clearly comfortable at his position, and according to the numbers we have, he's probably worth 10 or 15 runs above average in the field. Recently he's begun taking balls in the middle infield and getting some time at short, where last night he made a sensational diving stop to his left. The positional adjustment we have for moving from 3B to SS is worth about five runs, and there's little reason to believe that Hannahan won't be able to handle the change. He doesn't, however, have much of a bat, with a career wOBA of .298 and a ZiPS projection of .306.
