Time to give up on Sanchez?

I know it's early, and I know it's only Spring Training, but the stats are very, very bad:

2.2 innings pitched, 9 hits, 7 earned runs, 3 walks and only 2 Ks.

Opponents are hitting .529 against him!  More often than not batters are getting a hit when facing Sanchez.

It really stinks because we're paying him so much, but I just don't think it makes sense to take him north with the team.  He's just really, really bad right now.
