I worked a 17 inning game that was tied 2-2 after 7. Each team scored a run in the 9th innning. Each team scored 2 runs in the 13th (?) inning. Finally Shane Lechler (now the Pro Bowl punter for the Oakland Raiders) ended it with a home run in the 17th inning at 1:40 AM.
But the real kicker is that this was the 2nd game of a JV/Varsity doubleheader. We walked on the field at 4:00 PM and finally left at a quarter till two in the morning.
