I watched as an A player, playing in the finals, smashed TWO of his rackets during the changeover. He was winning 6-2, 5-2 at the time. He ended up winning the tourney with a 6-4 in the second set.
He complained about his lack of fire, his slow prep, and his mishits from the start of his warmup.
His opponent was a pusher who shouldn't have gotten that far.
