CHICAGO — It was a historically bad day for Didi Gregorius, personally speaking.

The shortstop, mostly outstanding in the field all season for the Yankees, committed a career-high three errors Monday in an 8-2 loss to the White Sox.

“A terrible day,” Gregorius said.

The first miscue occurred in the third inning when Gregorius, who had eight errors entering the day, bobbled Jose Abreu’s grounder. In the fourth, he fired high over Rob Refsnyder’s head at first base after fielding Jason Coats’ grounder, and in the eighth came another bobble, this time on a Tim Anderson grounder. The last error was the only one to lead to a Chicago run.

“I was trying to read the ball, there was a couple of bad hops but I tried to stay with it,” Gregorius said. “But tomorrow’s a new day, so I’m not worried about it.”

Of all of the Yankees’ issues this season, Gregorius’ fielding is not among them.

“It’s just unusual to see that from Didi,” Joe Girardi said. “I’m not too worried about that.”

Beltran back

Carlos Beltran (tight right hamstring) started his first game since last Tuesday, going 1-for-5 as the DH.

“I continue to progress,” he said. “This is something that isn’t going to be healed from one day to another. So I have to manage myself and deal with it.”

Beltran said “maybe” he could play the field Tuesday night.

Rough schedule

Girardi was not thrilled with a schedule that called for the Yankees to play Sunday afternoon in San Diego, then play another afternoon game Monday, two time zones away.

“You go out to the West Coast, you ought to stay out there a while,” Girardi said. “I don’t get it. It should be a three-city stop [west]. West Coast teams when they go to the East Coast should be three-city stops. But you can say all you want, if they change it for us, they have to change it for everyone, so the chances of it happening aren’t too good.”

Top pick debuts

Blake Rutherford, the Yankees’ first-round pick (No. 18 overall) who signed last week, made his professional debut Monday with the organization’ GCL West club. He played five innings in center and went 0-for-2 with a strikeout and a flyout.
