NEW YORK — Luis Severino pitched four dominant innings and reached 98.8 mph in his injury-delayed season debut for the Yankees, an 8-0 win over the Los Angeles Angels on Tuesday night that moved New York to the brink of clinching its 21st postseason appearance in 25 years.

A two-time All-Star and the ace of the Yankees staff, Severino got hurt while warming up before his first scheduled spring training appearance on March 5.

He began tentatively in game 152, opening with a 12-pitch walk to Brian Goodwin, but got sharper and allowed just a pair of singles. Severino walked two and struck out four, throwing 47 of 67 pitches for strikes and leaving to an ovation from fans tracking his pitch count. He had seven swings and misses on fastballs and two on sliders.

Severino’s return gives the Yankees a plethora of postseason rotation choices from a group that includes James Paxton (14-6), Masahiro Tanaka (10-8), Domingo German (18-4), CC Sabathia (5-8) and J.A. Happ (12-8).

While Severino was back on the mound, the Yankees announced reliever Dellin Betances tore his left Achilles’ tendon in his season debut Sunday at Toronto. He had tests done after he was sore Tuesday.

Severino was 19-8 with a 3.39 ERA in 32 starts last year but struggled late in the season. The Yankees at first this year diagnosed Severino with shoulder inflammation, but when the 25-year-old right-hander failed to improve he was sent for an MRI on April 9 that revealed a strained latissimus dorsi muscle. He didn’t throw off a mound again until a bullpen session on Aug. 9 and made three minor league injury rehabilitation appearances from Sept. 1-11.

New York lowered its magic number to one over Cleveland to clinch the Yankees’ 55th postseason appearance — 22 more than any other team. New York’s magic number dropped to two over Tampa Bay to wrap up the Yankees’ 19th AL East title, their first since 2012.

And at 99-53, the Yankees are on the verge of their 21st 100-win season, their first in back-to-back years since 2002-04.

Severino’s return follows the season debut on Sunday of left-hander Jordan Montgomery, out since May 2018 while recovering from Tommy John surgery.

Outfielder Giancarlo Stanton, limited to nine games this season, is due back Wednesday or Thursday after recovering from a knee injury.

Gleyber Torres hit his 38th homer, a three-run drive that capped a six-run fourth inning against JosÈ Suarez. One pitch earlier, Didi Gregorius doubled in two runs.

New York took a 2-0 lead in the second off NoÈ Ramirez (5-4) on Gio Urshela’s RBI single and Cameron Maybin’s run-scoring double.

Jonathan Loiasiga (2-1) followed Severino with two hitless innings as part of a six-hitter against the Angels, already assured of a losing record at 68-83.

LEADING OFF

A look at what’s happening around the majors Wednesday:

TWO GOOD ONES

Max Scherzer faces Adam Wainwright as the Nationals and Cardinals finish their pivotal series in St. Louis. Washington is fighting for position in the wild-card race while St. Louis is looking to hold off Chicago and Milwaukee for the NL Central championship.

Since returning from a trip to the injured list for a mid-back strain, Scherzer is 1-1 with a 3.91 ERA in five starts for the Nationals. The three-time Cy Young Award winner pitched five innings of three-run ball in a 5-0 loss to Atlanta on Friday night.

The 38-year-old Wainwright is 3-0 with a sparkling 0.45 ERA in three starts this month. The right-hander struck out seven in six innings in a 10-0 victory over Milwaukee on Friday.

HOMER VS. ROYALS

Right-hander Homer Bailey will pitch for the Athletics for a second time against his former Royals team in the clubs’ series finale, opposite lefty Danny Duffy. Bailey is 6-2 with a 4.72 ERA in 11 starts since the July 14 trade. Bailey was the winning pitcher in a 19-4 victory at Kansas City on Aug. 26. He worked 5 1/3 effective innings in a 3-2 victory at Houston in his previous start Thursday.

SANDY ROLLING

Miami Marlins right-hander Sandy Alcantara looks to continue his solid stretch when he takes the mound in Arizona. Alcantara has a 2.49 ERA over his last seven starts, working at least six innings in each outing. He tossed seven innings of one-run ball in a 1-0 loss at San Francisco on Friday. Mike Leake pitches for the Diamondbacks. He is 1-1 with a 3.86 ERA in September.
