Puerto Rico rode a big four run first inning and made it stand to upset the United States 6-5. Marcus Stroman was not sharp as he gave up hits to the first six hitters he faced. If not for a flyout double play where Christian Yelich threw out Yadier Molina at third the inning could have been much worse. Carlos Beltran still scored the fourth run on the play to give Puerto Rico an early 4-0 lead.
The United States tried to peck away at the lead. A Nolan Arenado leadoff double and Eric Hosmer single in the second inning scored one run. Buster Posey walked to put two runners on but Daniel Murphy grounded into 1-6-3 double play. With a runner on third and two out Brandon Crawford grounded to second.
Marcus Stroman settled down after the first inning and pitched into the fifth when two out back to back singles resulted in his departure. Buster Posey had hit a solo shot in the top of the fifth to pull the United States to within 4-2. With two outs and two runners on Mychal Givens retired Yadier Molina on a fly out to keep the score at 4-2.
Andrew McCutchen got a little heated in the top of the sixth after a strike three call and was ejected from the game. Adam Jones followed with a solo homer to pull the United States to within one run. There were chants of U-S-A echoing in the background with the crowd smelling victory.
It was not to be. In the bottom of the sixth the Puerto Ricans won the game, scoring two runs without benefit of a hit. Javier Baez was hit by a pitch to start the inning. He stole second and Andrew Miller replaced Givens. Eddie Rosario walked. After a T.J. Rivera strikeout Puerto Rico pulled a double steal to put runners on second and third with one out. Miller was still able to strike out pinch hitter Enrique Hernandez for the second out. Angel Pagan grounded to Nolan Arenado at third for what appeared to be the third out but Arenado threw the ball away, allowing two runs to score. Puerto Rico had the lead back 6-3.
The United States rallied in the ninth falling 90 feet short of tying the game. Edwin Diaz began the inning by walking Nolan Arenado and giving up a single to Eric Hosmer putting runners on first and second with no out. Buster Posey struck out but a wild pitch moved the runners up one base. Paul Goldschmidt also struck out. Brandon Crawford put a charge into the crowd with a triple to left field. Edwin Diaz bore down and struck out Josh Harrison to end the game.
There were 32,463, the largest crowd at Petco Park for a WBC game. The win clinched a spot for Puerto Rico in the final four. Who goes with them to Los Angeles will depend on the winner of the United States and Dominican Republic game. A win by the Dominican Republic would make it a repeat of the final four from the 2013 World Baseball Classic. The Dominican Republic made a nice come back to win an exciting 6-5 game in the first round. They hope to repeat those efforts tonight to advance.
