For any league with a DL slot, I think Glaus is a definite up. People will be crossing him off their cheat sheets in a lot of cases. If you swoop in and pick him up in the last few rounds, you can DL him. Once he returns, you have a nice power bat for your 3B/CI/UT spot. Any H2H leagues would also much rather a guy misses time in April than in August.
