I won't argue that Slaten is good, but to say it didn't even give us a shot is not supportable.
In his 7 outings since returning from the DL, he'd surrendered runs in 2 of them. That would seem to indicate that maybe, just maybe, we still would have a shot.
lol since returning from the DL:
4 IP 8 H 6 R 5 ER 1 BB 5 K (11.25 ERA, 2.25 WHIP)
It is almost unreal how bad he's been this year. The numbers don't even tell the whole story. Several times they would just bring him in for a batter or two and he would almost always put them on base or give up a big hit.
