I'm guessing it's a mixture of both aging and back issues. His family problems in Mississippi might have some sort of effect on his mental issues also.
His velocities are down. His fastball, change-up, curve, slider. All have dropped in velocity.
His K/9 is down significantly. His career average is 7.38/9 and this season he's got 5.9/9.
He's just not fooling anybody. Hitters are making contact more than 90 percent of the time in his pitches in the strike zone and more than 75 percent outside the strike zone. His career numbers are 86/60. His swinging-strike percentage also dropped from 9.4 career percentage to 7.
I love drafting for players that I like even if I have to pay more than the market price. I ended up drafting all Halladay, Lee, Oswalt. I had no intention of getting rid of any of them where all three have been one of my favorites for a long time and now they happen to all be pitching for my team.
I traded away Oswalt after he came off the DL because he just didn't look good on the mound. It didn't seem like a one game struggle.
I think a lot of people were fooled by the 1.74 ERA he had last season pitching for the Phillies in 80+ innings.
I don't want to say he's done. However, I do think he is regressing with injuries.
He's the same age as Halladay, but a lot more fragile.
