Final answer:
The ball slipped through the goalie's hands or became stuck in his mouth.
Step-by-step explanation:
The question is asking what happened to the ball when the goalie was distracted by sweat in his eyes. Based on the descriptions provided, it can be inferred that the ball slipped through the goalie's hands. In the first passage, it says 'the ball slipped out of McTeague's jaws as easily as it had gone in,' indicating that the ball was dropped.
Similarly, in the second passage, it mentions that the dentist could not stretch his jaws wide enough to slip the ball out, suggesting that the ball became stuck in the goalie's mouth.
