Re-read the passage where Felix and Antonio fight, starting at paragraph 69. How does the author build suspense during the fight?

paragraph 69: BONG! BONG! ROUND ONE. Felix and Antonio turned and faced each other squarely in a fighting pose. Felix wasted no time. He came in fast, head low, half-hunched toward his right shoulder, and lashed out with a straight left. He missed a right cross as Antonio slipped the punch and countered with one-two-three lefts that snapped Felix’s head back, sending a mild shock coursing through him. If Felix had any small doubt about their friendship affecting their fight, it was being neatly dispelled.
