It's one of the interesting bits from John Feinstein's book about Glavine and Mike Mussina. The book is good, but I wish there was more about baseball and less about strikes and contract negotiations.
Some other interesting bits:
- Mike Mussina would hold runners on first base by leaning over before the set and getting a glimpse of the runner between his legs.
- Glavine got a pain in his arm in the first weeks of his minor league stint, and Atlanta coach Johnny Sain cured it with five straight days of long toss (instead of rest or a visit to the doctor). Sain's thinking was that Glavine's arm just needed some stretching out to help make the adjustment from pitching infrequently in high school to the more-demanding professional routine.
