Stanton hit a go-ahead, two-run shot into the third-level balcony of the Western Metal Supply Co. Building in the left-field corner in the fourth inning and Jones robbed Baltimore Orioles teammate Manny Machado of a home run in the seventh to help the Americans beat the Dominican Republic 6-3 on Saturday night, eliminating the defending champions.
Team USA will face Japan on Tuesday night at Dodger Stadium for a spot in the championship game.
A number of big-name players declined to play for the United States. Manager Jim Leyland appreciates those who did sign up.
"There were a lot of people that respectfully declined and we're not going to throw anybody under the bus," Leyland said. "We're going to honor the people that accepted and are here. So we're moving forward and that's all we're talking about. ... And right now that's the only team I care about. And these players that are here are the only players I care about right now."
Those who were with Team USA certainly put on a show.
Stanton's homer gave the United States a 4-2 lead and put a charge into the sellout crowd of 43,002.
The slugger's shot was reminiscent of his Home Run Derby victory at Petco Park on July 11, when he peppered the far reaches of the big downtown ballpark, including hitting one onto the top of the 108-year-old brick warehouse.
"Yeah, it did kind of feel like the Home Run Derby," Stanton said.
Three innings later, Jones leaped and reached over the fence in the deepest part of the park in right-center to rob Machado of a home run. Machado tipped his helmet to Jones.
"I'm still in kind of shock that I even got to that ball," said Jones, who played at Morse High about 8 miles east of Petco. "I mean, off the bat I'm just like, 'This ball's hit really far, so just keep going, keep going. You know this California air's going to slow it down and just never quit.' That's just the style I play with. I don't mind running into a wall or two. I just kept going after the ball.
"I saw the replay after the game. It was a hell of catch," he added.
Robinson Cano then homered to left to pull the Dominican Republic to 4-3.
Andrew McCutchen gave Team USA some breathing room with a two-run double in the eighth, and Luke Gregerson pitched a perfect ninth to close it out.
This is the second time in four editions of the WBC that the United States has advanced to the semifinals. It lost to Japan in 2009.
The Dominican players, who rallied to beat the United States one week earlier in Miami in the first round, will disperse back to big league camps. They finished 1-2 in the second round after going 3-0 in the opening round.
Earlier on Saturday, Puerto Rico completed a 3-0 run through Pool F by beating Venezuela 13-2. Puerto Rico clinched first place in the pool with a 6-5 victory against the United States on Friday night and will play the Netherlands in the semifinals Monday night at Dodger Stadium. The championship game is Wednesday night.
Brandon Crawford hit a two-out single to left-center ahead of Stanton's homer, which was estimated at 403 feet and chased Dominican starter Ervin Santana.
The Dominicans jumped out to a 2-0 lead in the first on an RBI double by Cano and an RBI single by Carlos Santana. One run was unearned due to Crawford's throwing error at shortstop. Crawford threw out Nelson Cruz trying to score on Starling Marte's grounder, though.
The United States tied it in the third on Ian Kinsler's RBI grounder and Christian Yelich's run-scoring double.
The Dominicans had three more scoring chances but failed each time.
Gregory Polanco singled and Welington Castillo doubled to open the second before Danny Duffy retired the side.
They threatened again in the fifth when Machado hit a leadoff single to chase Duffy. Cruz hit a one-out double off Pat Neshek, who then retired Carlos Santana on a popup and struck out Marte.
Neshek pumped his fists as he walked off the mound.
"This was a very difficult game," Dominican Republic manager Tony Pena said. "You have (eight) players on base and we couldn't do the best. I feel very proud of each one of them. I won't point to any one of them. Simply the U.S. team (made) the right pitches at that particular time frame and that's what cost us the game."
Duffy allowed two runs, one earned, and six hits in four-plus innings. He struck out one and walked one.
Ervin Santana gave up four runs and six hits in 3 2/3 innings. He struck out two and walked none.
