What kind of trade is this?

Houston traded pitcher Dan Wheeler to Tampa Bay for utility player Ty Wigginton on Saturday.

The move begs one question -- why? Sure Wheeler has struggled this season after putting together three solid years in the Astros bullpen.

Trading Wheeler made sense but to get Wigginton back is the confusing part. Manager Phil Garner already has enough trouble finding at-bats for Mark Loretta, Morgan Ensberg, Craig Biggio and Mike Lamb. Now Garner has another solid hitter who doesn't have a solidified position.

It should be interesting to see if Houston general manager Tim Purpura will flip Wigginton for someone else or make more moves period.
