Maybe I'm sensitive about this because I'm a Webb fan, but I'm watching the TBS telecast at the start of the NLCS game 1, and Caray, Brenly and Gwynn are saying things like "we'll see if his sinker is working," "we'll know right away if he has his good stuff" and "he hasn't pitched well against the Rockies the last two years."
Someone who only watches playoff baseball, and doesn't watch every game, may not know who Brandon Webb is. The commentators are painting a picture that sometimes Webb is off so we've got to watch carefully to see if the good pitcher shows up, or the bad. Sometimes his sinker doesn't work? Sure, but not very often.
It isn't enough to say he won the Cy Young last year. Perhaps it's worth mentioning that if Peavy hadn't been lights out all year, Webb would probably win the Cy Young this year too. It wouldn't surprise me if hitters in the National League would rather face any other pitcher. As Derrek Lee said, "Hitting his sinker is like hitting a bowling ball."
Over the last two years, he is quite simply the best pitcher in the National League. Period.
