SAN FRANCISCO — Saying the Yankees have been injury-plagued this season is like saying the Giants are a rancidly bad baseball team.

The words themselves still don’t quite capture it.

On a perfect sun-splashed afternoon by the Bay inside Oracle Park, the Giants’ glorious home, those two worlds intersected in the Yankees’ 11-5 victory in front of 34,540 on Sunday.

Domingo German pitched five terrific innings before being touched up in the sixth, though by that point the Yankees had an 8-0 lead and were well on their way to their 11th victory in 13 games. That was the result of production from another makeshift lineup, led by two-run homers by Gleyber Torres and Gary Sanchez, who had three RBIs, and Luke Voit’s three hits and two RBIs.

But the Yankees (17-11), already with a fully stocked injured list of 13, also saw two key players leave the game.

DJ LeMahieu, who fouled a ball off his right knee in Friday’s win here, left in the third inning with inflammation in the knee, the result of it stiffening up.

“It kind of got more painful as the game went on,” said LeMahieu, who walked with an ever-so-slight limp through the clubhouse.

X-rays were negative, and the infielder will undergo an MRI Monday.

Of being in the lineup Tuesday in Phoenix when this three-city, nine-game trip continues, LeMahieu said: “That’s my mindset.”

Gio Urshela, a standout at third base with Miguel Andujar out, left after getting hit in the left hand by an 89-mph cutter thrown by Nick Vincent in the fifth inning. Urshela, 2-for-2 to that point to raise his average to .351, was sent for X-rays, which also came back negative.

“Hopefully it feels better tomorrow on the off day and then we’ll see what happens,” Urshela said. “Once I got hit, because of the pain and sensation you have, automatically you think the worst, but eventually I was able to move my fingers and got movement back and kind of took a deep breath there.”

Rookie Thairo Estrada replaced LeMahieu at second — and produced two hits, continuing to show zero nerves regardless of what is thrown at him – and Tyler Wade, who started the game in leftfield, shifted to third. Cameron Maybin, acquired from the Indians on Thursday and pressed into duty Friday and Saturday, took over for Wade in left and singled home a run in the ninth before scoring on Wade’s two-run single.

The bench was so short that Aaron Boone sent up pitcher J.A. Happ to pinch hit for German when his turn came up in the seventh (Happ grounded to second).

“We have a really good minor-league system,” said Sanchez, whose eighth homer of the season made it 8-0 in the sixth. “Right now, to see all these young guys come up and have an opportunity to play and show that they can produce at this level, it’s great.”

German (5-1, 2.56 ERA), who came in with the fourth-lowest ERA in the AL (1.75) and second-lowest WHIP in the majors (0.82), is among those, starting the season in the rotation because of injuries to CC Sabathia and Luis Severino. He allowed all of one hit entering the sixth before the Giants (11-17) scored four runs to make it 8-4.

The Yankees, now 6-1 on the trip, had 14 hits.

They struck early against Giants righthander Dereck Rodriguez, 26, the son of Hall of Famer Ivan “Pudge’’ Rodriguez, scoring two runs each in the first, second and third innings, the last two on Torres’ fifth homer.

“We’ve got good players in that room,” Boone said of the injury adversity. “And they’ve all continued to step up and really embrace this thing. They’re all doing their job really well. Proud of how they’ve rallied around one another.”
