Wigginton, 33, was batting .233/.309/.383 with 2 HR before his demotion, splitting playing time between 3B, LF and 1B (as Todd Helton's primary backup). In his 10 games before hitting the DL, however, he upped his batting line to .280/.367/.560, and had all but solidified himself as the starting 3B, given Ian Stewart's demotion.
Stewart, 26, has batted a pitiful .064/.154/.085 so far this season. He was demoted earlier in the season, but was quickly called back up after Wigginton's injury, hoping that the string of regular ABs would help him break out of his funk. Fact is, Stewart missed half of Spring Training and has been desperately playing catchup since then - and has yet to catch up.
Stewart likely won't be back up with the MLB club anytime soon, and there's rumblings that he might be a change-of-scenery trade candidate.
Wigginton will likely return as the full-time 3B, possibly giving Jose Lopez the 3B time when Wigginton is spelling Todd Helton at 1B.
