Miami ? Hobbled and humbled in the World Baseball Classic, Team USA is still swinging.

David Wright sliced a two-run single that capped a three-run rally in the bottom of the ninth inning Tuesday night, and the injury-plagued Americans qualified for this weekend’s semifinals with a 6-5 win over Puerto Rico.

Wright’s hit with one out eliminated Puerto Rico from the tournament. The Americans advanced to the next round at Dodger Stadium.

It was an especially sweet victory for the U.S. after Saturday’s embarrassment against Puerto Rico that triggered the mercy rule when the Americans fell 10 runs behind, ending the game in the seventh inning.

This time they played a full nine, saving their best for last in the 3-hour, 54-minute marathon.

Trailing 5-3, Team USA began its rally when Shane Victorino and Brian Roberts singled to the start the ninth against J.C. Romero (1-1). Derek Jeter flied out, Roberts stole second, and Jimmy Rollins walked on a 3-2 pitch.

Fernando Cabrera came on to pitch, and he walked Kevin Youkilis to force in a run.

Wright then lined a 2-1 pitch just inside the right-field line, raising his fist when the ball dropped in. The New York Mets star was mobbed by teammates near second base after two runs scored.

The clutch hit came after the Americans stranded seven runners in scoring position in the first eight innings.

The WBC has some marketing to do, as Tuesday’s modest crowd of 13,224 showed, and the tournament’s version of the Yankees provided a boost by making the final four for the first time. Team USA will play Venezuela in Miami’s final game of round two tonight to determine seedings for the semis.
