SAN FRANCISCO -- DJ LeMahieu and Gio Urshela became the latest Yankees to get hurt as New York completed a three-game sweep of the San Francisco Giants with an 11-5 win on Sunday that included another long home run by Gary Sanchez.

LeMahieu was removed in the bottom of the third because of right knee inflammation. He says the injury is on the outer edge of his right knee.

Manager Aaron Boone said after the game that he thought the infielder had a deep bruise. Although X-rays taken during the game were negative, LeMahieu will have an MRI on Monday in Phoenix, where the Yankees will spend a day off before they face the Arizona Diamondbacks in a two-game series starting Tuesday.

"Just hopeful that it's something that stiffened up on him in the day game," Boone said.

The injury stemmed from a foul pitch that LeMahieu rattled off his right knee in Friday's game. He finished that game and played all of Saturday's game. Following both, he had the knee wrapped with ice. On Sunday, LeMahieu's knee was wrapped in gauze as he spoke with reporters.

The infielder contends that he didn't do anything to further hurt himself Sunday. The knee just "got more painful as the game went on," he said.

Asked if he thought he'd be in the Yankees' lineup on Tuesday, LeMahieu said, "That's my mindset."

In his first season with the Yankees, LaMahieu is hitting .310 with 15 RBIs.

Urshela left after he was hit on his left hand by an 88.5 mph cutter from Nick Vincent in the fifth. Urshela had two hits Sunday and is batting .351 with six RBIs in 57 at-bats.

The Yankees said X-rays on him were also negative.

"Just kind of a day-to-day thing," Boone said. "Obviously, the off day is coming at a good time for us. Hopefully we avoided some serious injuries."

Urshela, who was hit on the top of his left hand, just above the wrist, said no further testing would occur on his hand. He'll see how he feels after Monday, but he is hopeful to be back in the lineup at Arizona.

"Thank God the results are negative," Urshela said, speaking through an interpreter.

Although he was removed after slowly walking up the first-base line and being evaluated on the field, Urshela said he started feeling better about his injury pretty soon after.

"Once I got hit, because of the pain and sensation you have, automatically you think the worst," Urshela said. "But eventually I was able to move my fingers and got movement back and took a deep breath there."

New York has had 15 players on the injured list this year, and just two have come back: Sanchez and pitcher CC Sabathia. Still, the Yankees are 6-1 on their road trip after outscoring the Giants 21-12, and New York improved to a season-best six games over .500 at 17-11 by winning for the 11th time in 13 games.

"We've got really good makeup in that room," Boone said. "It's something that's important to us to have those kind of people, and we have that -- guys that are tough, that are prepared.

"I always felt with this team that through ups and downs, whatever, they're really good at turning the page. But there is an extra focus right now that with what we're going through, guys are coming in ready for any kind of role, ready for any kind of situation, and they're delivering."

With a depleted bench, the Yankees used pitcher J.A. Happ as a pinch hitter in the seventh inning, and he grounded out.

Sanchez and Gleyber Torres hit two-run homers as the Yankees built an 8-0 lead by the sixth inning, and Luke Voit added three hits and a walk to extend his on-base streak to 39 games.

Domingo German (5-1) took a shutout into the sixth before tiring and is now tied for the major league lead in wins. He allowed four runs and five hits in six innings.

New York took a 2-0 lead in the first, Voit doubled the lead with a two-run single in the second, and Torres homered in the third. Sanchez's sixth-inning drive left the bat at 111.8 mph and traveled 430 feet, landing near the top of the left-field stands. That nearly matched Sanchez's first career grand slam Saturday, which traveled 467 feet.

Kevin Pillar homered and had three RBIs for the Giants, who are last in the NL West at 11-17.
