Diamondbacks rookie Taylor Clarke was an impressive winner in his Yankee Stadium debut, five days after the birth of his daughter, and Arizona got home runs from Christian Walker and Carson Kelly in a 4-2 victory Tuesday night.

Nick Ahmed hit an R.B.I. single, and Adam Jones had an early sacrifice fly for the Diamondbacks, who have won all three meetings with the Yankees this year. Arizona, 14-5 in interleague games after winning nine of its past 10, will go for a season sweep Wednesday afternoon.

J.A. Happ (8-6) allowed three runs in six innings for a struggling New York staff that gave up 79 runs over the previous eight games. General Manager Brian Cashman is shopping for pitching help ahead of Wednesday’s trade deadline — but time is running out.

“We know we’re capable of something really special with all the guys we have in that room right now,” Manager Aaron Boone said. “Whatever happens or does or doesn’t happen over the next 24 hours, I don’t expect our room to change from a confidence standpoint.”
