MIAMI (AP) — Mario Chalmers gets screamed at more than any other Miami Heat player. And that's just by his teammates, who think nothing of getting in their point guard's face to provide instant criticism.

It's not disrespect. They do it because Chalmers can take it — and in Game 4 of the NBA Finals, he gave his team reason to scream with joy.

Chalmers scored 19 of his 25 points in the second half, coming up big after LeBron James hampered down the stretch with a leg cramp, and the Heat moved one win from a title by beating the Oklahoma City Thunder 104-98 on Tuesday night.

The Heat lead the series 3-1, and can close it out at home Thursday.
