WASHINGTON — Nationals catcher Wilson Ramos had surgery on his right knee and his rehabilitation is expected to take up to eight months.

Washington says Ramos had the operation on Friday, hours after the team’s season ended with a 4-3 loss to the Los Angeles Dodgers in Game 5 of their NL Division Series.

Ramos was injured last month, during the last week of the regular season. During Friday’s surgery, he had his knee’s ACL reconstructed and the medial meniscus and lateral meniscus repaired.

He batted .307 with 22 homers and 80 RBI this season.

YANKEES: Owner Hal Steinbrenner is enthused about the team’s prospects after watching many of them play in instructional league games this month.

New York boosted its system by acquiring shortstop Gleyber Torres, outfielders Clint Frazier and Rashad Crawford and left-hander Justus Sheffield in trades for veterans Aroldis Chapman, Andrew Miller and Carlos Beltran.

Gary Sanchez, Aaron Judge and Tyler Austin joined the big league team in August and sparked the Yankees to a wild-card run, one that ultimately fell short

“The last two months, we had one bad road trip and it was bad,” Steinbrenner said Friday.

“But other than that we were right in it. Being able to bring some of those kids up the beginning of August when the games really mattered, I think we learned a lot and saw a lot. We saw what they were made of. It was a great experience for them.”

BOOSTED BY the Los Angeles Dodgers and Chicago Cubs, the NL Division Series outdrew its AL counterpart on television.

The Dodgers’ 4-3 win over the Washington Nationals in Game 5 Thursday night was seen by an average of 4.52 million viewers on FS1, boosting the network’s NLDS average to 3.69 million for nine games.

Fox said Friday its average for the Dodgers-Nationals and Cubs-Giants matchups increased 32 percent from last year’s 2.8 million for the ALDS and by 18 percent from the 3.1 million for NLDS coverage in 2014.

Thursday night’s finale averaged 4.76 million viewers, including people who watched on Fox Deportes and online.

TBS’s coverage of the ALDS between Toronto and Texas, and Cleveland and Boston averaged 3.1 million viewers. Last year’s NLDS on TBS, featuring Dodgers-New York Mets and Cubs-St. Louis Cardinals matchups, averaged 5.4 million viewers, up from 3.6 million for the 2014 ALDS.

VIN SCULLY IS keeping busy in retirement, joking with Jimmy Kimmel that he’s been to the hardware store since ending his 67-year Hall of Fame broadcasting career with the Los Angeles Dodgers.

In his first television interview since calling his last game on Oct. 2 in San Francisco, Scully told the late-night talk show host Thursday that he has a “very important engagement” on Monday.

“I’m lecturing at the sixth-grade school at Saint Mel’s,” Scully said, referring to the Catholic elementary school in Woodland Hills where his grandson and granddaughter attend.

“If I can’t think of something to do, someone out there will,” he said, noting that he has 16 grandchildren.
