TORONTO — Yankees manager Boone avoided using Gleyber Torres on Thursday night after the All-Star second baseman had tests in New York on Wednesday to find the cause for lower abdomen pain on his right side. He was forced out of games Sunday and Wednesday.

“We will go day-to-day with it,’’ said Boone, who started Breyvic Valera at second base for a second straight game and had planned just light work for Torres on Thursday. “Ramp him up [Friday] and see where he is at.’’

Boone said he was hopeful Torres could return to the lineup “sometime this weekend.’’

Valera went 1-for-3 and scored two runs in the Yankees’ 12-6 win over the Blue Jays.

If Gary Sanchez came through his Triple-A rehab game Thursday night, the plan is for him to come off the injured list and catch for Masahiro Tanaka on Saturday.

Sanchez went 0-for-2 in the second game of his rehab stint for Scranton/Wilkes-Barre after going 1-for-3 on Wednesday.

Since Sanchez went on the IL with a strained left groin after leaving a game on June 23, Austin Romine and Kyle Higashioka have combined to hit .351 (20-for-57) with seven homers and 19 RBIs. Romine went 2-for-5 Thursday.

Luis Severino is scheduled to throw his first bullpen session of the year on Saturday. It’s the first time since spring training that the former staff ace won’t be throwing off flat ground. He was initially diagnosed with a right shoulder impingement and later with a lat problem.

Asked if Gio Urshela’s breakout season could lead the Yankees to discuss moving Miguel Andujar from third base to the outfield next year, Boone said that subject hasn’t surfaced. Urshela, with his two-run homer in the first inning Thursday, extended his hitting streak to 13 games, which is the longest active streak in the majors.

The Yankees are 7-3 against the Blue Jays this year and 43-14 versus AL East teams.
