HOUSTON — The last time the Yankees swept a three-game series against the Astros, Jasson Dominguez was 10 years old.
Ten years later, he helped them accomplish the feat again by capping off his first series in the big leagues with an exclamation point.
Dominguez crushed his second home run in his third career game Sunday night, a two-run shot that broke a tie and lifted the Yankees to a 6-1 win over the Astros at Minute Maid Park.
Fellow rookies Austin Wells and Oswald Peraza later added RBI doubles in the ninth inning, after Glyeber Torres clubbed a solo homer, for some insurance to finish off the weekend in convincing fashion.
The Yankees (68-69) ended a 10-day, 10-game road trip by winning six of their last seven and cooling off the Astros (77-61).
For most of the four years since Dominguez signed with the Yankees for $5.1 million out of the Dominican Republic, he has been out of sight, if not out of mind.
But his arrival this weekend did little to tamper the hype that has long surrounded him as he delivered the Yankees a jolt.
After homering off Justin Verlander on the first swing he took in his debut Friday, Dominguez took Cristian Javier deep Sunday night.
One batter after the Yankees had tied the game on DJ LeMahieu’s RBI double, Dominguez got an 0-1 slider on the inside part of the plate and drilled it for a two-run shot and the 3-1 lead.
Dominguez became just the fourth Yankee in franchise history to hit two home runs in his first three career games, joining Aaron Judge, Yogi Berra and Joe Lefebvre, per ESPN Stats & Info.
Wells also finished his weekend on a high note.
Before ripping a double in the ninth to drive in another rookie, Anthony Volpe, to make it 5-1, the catcher had thrown out the first runner who attempted to steal a base on him in the fifth inning.
In the minor leagues this season, Wells had caught just 15 base stealers on 116 attempts, but he is 1-for-1 through his first three games in the big leagues.
Michael King turned in another strong start — his second straight on full rest — tossing five innings of one-run ball as he continued to stretch out his pitch count to 69.
He scattered five hits and walked none while striking out four.
The Astros only got to King in the first inning when Alex Bregman and Yordan Alvarez hit back-to-back singles and Kyle Tucker followed with a sacrifice fly.
Replacing King, Tommy Kahnle retired all six batters he faced to keep the 3-1 lead in check.
Jonathan Loaisiga then worked out of a jam in the eighth inning by getting Jose Altuve to ground into a double play.
