Twins infielder Trevor Plouffe has added 10-12 pounds of muscle during the offseason, according to the Star Tribune.
Plouffe enters the season expecting to start at third for the club. The 27-year-old hit .254/.309/.392 in 477 at-bats last year. With prospect Miguel Sano expected to make his major-league debut at some point during the season, Plouffe could find himself fighting for a role if he can't get off to a strong start.
