You're conveniently ignoring the fact that he was a LOOGY, Doij, he's a guy that's used to get a guy or two out, then hit the showers.
Let me ask you this, and you should answer honestly:
How many times did we see this?
Red Sox- Yankees: 7th inning, tie game.
Lopez gets called on to face Matsui and Cano.
Matsui flies out to right.
Cano walks.
Did he do his job?
That is the tying run right there, on a WALK, and a reliever who can't throw strikes is useless, and in Lopez' case, dangerous, why?
I mean he got one out, but he left the winning run ON BASE, that's not what a LOOGY's supposed to do, he can give up the hit, but walks are totally unacceptable, and that was exactly the Lopez special.
I seriously hope you're joking by trying to use ERA + to try to measure a one or two hitter reliever, because you're doing it wrong.
Javier Lopez sucks monkey tits, he sucked in '07, he sucked in '08, and he sucks now.
