Firebug suggests that it is using browser caching, but that it isn't using gzip compression. I haven't dug deeper to check though, just noticed and thought I'd mention it.
Sinker: League (not sure whether they were sinkers or two seamers in general, but they had the movement of both).
Invent-a-pitch: Cone (wish we had seen him as a Jay in his prime)
Eephus: Lilly
He didn't do it consistently (only saw it a handful of times), but Halladay earlier on in his career threw a couple mid 90's sinkers that acted like forkballs.
I really think this poll needs to be split up into one for each pitch type.
Some great choices on that list (and one or two I'm hoping are jokes)! Probably unfair to pick across different pitches, but rather rate by each pitch type.
That Henke forkball would absolutely disappear, but it's hard to beat the Clemens fastball at 98mph across the letters. Absolutely unhittable. The Hentgen called strike fastball a foot off the plate was pretty nasty too lol. He was a master at expanding the zone.
In the developer console. Seems to have changed now, but is saying that there's a null style set. Still seeing the Piwik one, but that will probably go when caching changes.
I doubt it's part of any of your issues, but in the chrome console it says there's a syntax error in piwik.js, and a typeerror in forum.php line 1280.
You also don't appear to have server compression enabled.
His off-speed wasn't as sharp tonight. It was devastating in the spring though (and looked nasty in his first start, they just knew what was coming), so might just have been the weather tonight.
