BALTIMORE _ Gleyber Torres belted two more home runs against the Orioles, putting the Yankees in reach of another late victory.
Gary Sanchez belted a go-ahead three-run homer in a four-run ninth, lifting the Yankees to a 10-7 win before just 16,457 fans at Camden Yards.
Winners of 11 of their last 14 games, the first-place Yankees (29-17) opened a full game lead on the idle Tampa Bay Rays atop the AL East.
Against the division's cellar dwellers, the Yankees came all the way back from a 6-1 deficit, due to another ineffective outing by J.A. Happ.
Trailing 7-6 entering the ninth against closer Mychal Givens, the Yankees opened with base hits by Brett Gardner and Cameron Maybin, setting up Aaron Hicks' game-tying sacrifice fly.
Givens should have escaped with the game tied, but O's catcher Pedro Severino allowed Luke Voit's pop up to drop foul, several feet behind him.
Underscoring how dreadful the Orioles' season has been, Givens walked Voit before surrendering Sanchez's 13th home run of the year _ delighting the many Yankees fans among the sparse crowd.
And it was a turnabout of sorts for Voit, who dropped an easy foul pop in the Orioles' sixth, leading to a run that gave Baltimore a 7-3 lead.
Ten starts into the season, Happ is still trying to find his way.
And he's consistently failing to keep the ball in the ballpark, a year-long trend that continued for the Yankees' lefty on Monday night at Camden Yards.
Happ served up two more home runs and failed to make it out of the fourth inning.
Monday marked the fourth time in 2019 that Happ has faced Baltimore (15-32), owners of the AL's worst record.
Happ is 1-1 with two no-decisions in those starts, charged with 14 earned runs in 17.1 total innings (7.27 ERA).
Last year with the Blue Jays and Yankees, Happ went 3-0 with a 1.55 ERA in five starts against the Orioles.
Of the 13 home runs yielded this year by Happ, seven have been hit by the Orioles _ including third-inning solo shots on Monday by Hanser Alberto and Renato Nunez.
All told on Monday, Happ was charged with six runs on nine hits and one walk in just 3.2 innings, leaving the Yankees in a 6-1 hole.
Happ has served up at least two homers in five of his 10 starts this year, with the majority of his home runs (9) coming at Yankee Stadium.
As long as Torres is in a lineup against the Orioles, the Yankees have a puncher's chance in any game.
With just a shade over a year's service time in the big leagues, Torres has made a career of feasting on Baltimore pitching.
Torres greeted reliever Shawn Armstrong by belting a leadoff homer in the eighth, cutting Baltimore's lead to 7-6.
It was Torres' 10th homer this season and it survived an umpire's crew chief challenge; a fan wearing a Yankees jersey in the front row nearly interfered with left fielder Dwight Smith Jr.'s leaping attempt.
Torres blasted three homers against the Orioles last Wednesday, during the Yankees' doubleheader sweep.
In 20 career games versus Baltimore, Torres has hit 11 homers. He's belted six home runs in 10 games at Camden Yards.
After serving up Torres' ninth homer of the year, a solo shot in the second, Orioles starter Andrew Cashner gave up two runs in the sixth and exited with a 6-3 lead.
D.J. LeMahieu's RBI single and a throwing error by Smith Jr., plating a run, cut Baltimore's lead to 7-5 in the seventh.
Masahiro Tanaka and James Paxton showed some additional progress on Monday.
Drilled by a sharp grounder above his right ankle in Saturday's start, Tanaka (bruised right shin) arrived at the ballpark "feeling well," according to manager Aaron Boone.
Tanaka is scheduled to throw his usual between-starts bullpen session on Tuesday, in hopes that he'll be able to take his regular turn in Thursday afternoon's series finale at Camden Yards.
Sidelined since May 4, due to left knee inflammation, Paxton is scheduled to throw another bullpen session on Tuesday.
After that, the Yankees will determine whether the lefty is able to slot back into the rotation this weekend at Kansas City.
