He has always crushed lefties. OPS+ doesn't really work on a linear scale so that you can say an OPS+ of 8 means 8% of average. OPS+ can actually be negative. OPS+ of 8 means...well, I can't say exactly what it means, but suffice to say it's very impressive (or horrible, if we're talking about batters).

Unless you think Romero is the best pitcher in history, something's up.

With the Phillies, he comes in to face left-handers who generally don't stand a chance against him. I don't know how they handled him in Boston, but here he's been very reliable. We don't use he word "fluke". As for Romero, how many "fluke years" does he have to have before you admit that the guy is a good pitcher?

Many relievers also start innings or come in with no one on base. As much as people knock using ERA or other methods for relievers, those who are used exclusively at the start of an inning, can pretty much be judged by standard pitching stats. vincent75% IRS% can't be the only meaningful stat.

This is why there are no closers: http://www.bb-ref.com/pi/shareit/6PeS Of the 26 guys to have at least 15 saves so far this year, only 2 have inherited as many as 20 runners, and therefore weren't eligible for the list. Papelbon has inherited 17 runners and stranded them all!

In save situations, he's been absolutely unhittable, giving up just 1 ER I think, recently to Boston. In non-save situations, he's been hit around pretty well, doing only a bit better than league-average. And that split has been consistent all year.

Guess you only use him in pressure situations... He actually had an ERA of 3.34 at one point just before the all-star break, and he stranded his first 23 inherited runners. He hasn't done so well since then: IS/IR = 0.55, and 13 ER in the last 5 IP with no inherited runners.
