"slippage of the differential"

This was Fox broadcaster Steve ("Psycho") Lyon's eloquent description of the difference in speed between Roy Oswalt's fastball and breaking ball. I think I did that a few times in calculus...

Also, Fox is classless in its baseball broadcasts just as it is in just about everything else. The Division Series games are broadcast by both Fox and ESPN. During the ESPN broadcasts, the games that will appear on both stations are advertised during the games. During Fox broadcasts, however, it's like the ESPN telecasts don't even exist. The most egregious cases are during, say, game 1 of a series when Fox advertises a game 3 that will appear on Fox and never even mentions the second game that will appear on ESPN. How incredibly lame...

(Postscript: During this evening's Astros-Braves game, I finally saw Fox advertise one the games being shown on ESPN, so they're not being lame 100% of the time...)
