Everyone's all about Houston Street, myself included, and justifiably he's getting comparisons to Brad Lidge. But I think Farnsworth is coming into his own as well, and I may go so far as to say that he could end up being a dominant closer sooner than later. Percy is solid, but he's old and injury prone... and with Oogie off to the Phillies that means Farnsworth is the sole setup man for Percival until he goes down again, and in the meantime Farnsy will pick up a save or two when Percival needs a day off.
Now, I know the arguments against him... he can throw 100MPH but he can't locate. When he gets into trouble, he doesn't pitch his way out of it, he throws his way out... and he gets lit up when he does that. But he hasn't done that this year, in fact he's kept his cool and really performed well:
In 27 innings he's got 1 win, 1 save, 11 holds and a key stat 36K. 36K/27IP is a very nice ratio, Brad Lidge like. He's got a polished 1.11 WHIP and a 2.33 ERA. He's also only walked 9 batters thus far, so he's clearly locating his pitches and using that cannon of an arm to burn them in. Now, he could fall apart... he's done nothing to prove that he can maintain this... oddly every other year starting in 2001 to present, he's had a good season, then a bad, then good, etc...
...or he could be the next Brad Lidge.
