The Cards had a better rested Gibson, who is the best RH pitcher I've ever seen. No disrespect to Pedro, but Bob was greater for a longer period of time. Hell, Gibson was one of the main reasons MLB lowered the pitching mound
Btw, if I'm not mistaken, in Lonborg's 2 wins against the Cards in that '67 WS he gave up a total of 3 hits. He was amazing.
