Which position player gets left off the the first round of the playoff roster?

Going into today's last regular season game, the Crew still has 14 positions players. I think Lauer is a lock to be the pitcher left off Tuesday's roster, but which position player will they/should they leave off of Tuesday's playoff roster.

Currently, the Crew has 6 infielders and 6 outfielders listed on their roster, so I suspect it will be one of the outfielders. Canha has only hit .154 over the past 7 games, but can also play 1B; Mitchell has fanned in 11 of his last 24 AB's, so my prediction is Mitchell.

Any other opinions?
