SEATTLE — Andrew McCutchen has been around long enough to understand 17 at-bats was far too small a sample to judge a 10-year big leaguer.

Still, those 17 at-bats came in his first week with the Yankees and included just one hit: a single.

So when the 31-year-old launched a two-run homer in the third inning of the Yankees’ 4-0 win over the Mariners Friday night off lefty James Paxton, the team’s new right fielder was asked if he had been frustrated.

“No frustration because overall I was having good swings, taking good passes on balls and grinding out at-bats,’’ said McCutchen, who followed Gleyber Torres’ two-run homer in the second. “I wasn’t frustrated; it was just a matter of time. The hits will come, the hits will fall. It’s good to have a big hit like I did tonight.’’

McCutchen, the NL MVP with the Pirates in 2013 who came from the Giants on Aug. 31, viewed the homer, his 16th overall of the season, as a possible ignitor.

“Hopefully, something like this gets you going,’’ McCutchen said.

The right-handed hitting McCutchen started a seventh straight game in right field Saturday night and led off against right-hander Felix Hernandez with Brett Gardner hitting ninth for a second straight game and fifth in the past seven.

McCutchen likely will be manager Aaron Boone’s choice until Judge is ready to return.

What happens then isn’t clear. McCutchen has been working in left field during early sessions and could be a platoon option with the left-handed hitting Gardner in left when Judge returns.
