Some first impression by Justus Sheffield.

The 20-year-old lefthander, among the four prospects the Yankees got from the Indians in the Andrew Miller deal, struck out 11 in six innings in his debut with the Tampa Yankees (high Class A) Friday night. He allowed one run, two hits and one walk in a 7-1 victory over Daytona.

“Everyone talks about Frazier, and I get it,” one National League talent evaluator said Saturday, referencing the centerpiece of the trade, outfielder Clint Frazier, now at Triple-A Scranton/Wilkes-Barre. “But for me, if I’m the Indians, [Shef field’s] the one I wouldn’t have wanted to lose.”

In addition to Frazier and Sheffield, the Yankees received righthanders Ben Heller and J.P. Feyereisen. Feyereisen is with Double-A Trenton and Heller, who more than a few believe will be in the Bronx before year’s end, is with Scranton/Wilkes-Barre.

Oops

After starting the sixth inning with a walk, Brett Gardner short-circuited a potential rally. When Jacoby Ellsbury hit a broken-bat liner to right, Gardner took off on contact, never looked back and was halfway to third when rightfielder Abraham Almonte made the catch. Gardner easily was doubled off first.

“I just thought it was going to fall,” he said. “Almonte was playing him a little more over in the gap and a little deep, and I was almost positive it was going to fall. Obviously, it was a bad read by me. One of those things where I got a little bit greedy and I paid the price for it.”

McCann a first option

Joe Girardi plans to have Brian McCann take some grounders at first, primarily as an insurance policy in case Mark Teixeira’s right knee acts up.

“He’s done it before and is pretty comfortable over there,” Girardi said. “Right now, knock on wood, he’s [Teixeira] pretty good, but sometimes one turn of that knee, something happens.”

McCann was the DH Saturday and went 0-for-4, ending a 10-game hitting streak.
