MADRID, Spain — Manu Ginobili missed a key free throw and Spain edged Olympic champion Argentina 90-88 today.

World champion Spain improved to 3-0 in Olympic warmup games.

Jose Calderon led Spain with 18 points. Spain outrebounded Argentina 32-28 before nearly succumbing to a late collapse.

Ginobili missed the first of three free throws with seven seconds left and a chance to tie it at 89. The San Antonio Spurs guard, who scored 11 of his 18 points in the final period to rally Argentina from a 10-point deficit, hit the next two to cut it to 89-88 before Ricky Rubio made a free throw for Spain.

Ginobili had a chance to tie it following a Juan Carlos Navarro turnover with 18 seconds remaining, but the Argentine missed a running layup.

Paolo Quinteros' turnaround jumper for Argentina at the buzzer bounced off the rim.
