Yu Fei hadn't even officially played the penny card against Shaquille O'Neal, and O'Neal's mindset was already a bit shattered by the penny's performance.
In terms of performance, the penny wasn't that good either, it just happened to be enough to put pressure on O'Neal.
In the remaining minutes of the first quarter, penny made 3 shots and hit 2, both baskets coming from post-pick-and-rolls. After he scored the second basket, Miami Heat substituted O'Neal out.
Without O'Neal on the court, penny seemed to have his energy drained and afterwards only took one shot, which he bricked.
The Heat, mindlessly pushing inside, were down by 13 points to the Bucks by the end of the first quarter.
In the second quarter, Dwyane Wade came out all guns blazing, unstoppable in isolation and also getting the benefit of the whistle on the road, he quickly poured in 9 points, closing the gap from 13 points to 7, prompting the Bucks to bring Yu Fei back early.
