TORONTO — Mookie Betts doesn’t get too caught up in statistics. But when he does take a look, it’s to see how many runs and RBIs he has.

The day-to-day variables of OPS or WAR aren’t worth his time.

“I focus on the things that can only go up. That gives you a clear mind and you can worry about less,’’ Betts said Saturday after the Red Sox beat the Toronto Blue Jays, 5-2.

Betts was 3 for 5 with two doubles and two runs scored. He is hitting .356 with a 1.215 OPS, 29 extra-base hits, 41 runs, and 27 RBIs.

Runs are what Betts likes most.

“As a leadoff hitter, that’s what I’m supposed to do,’’ he said. “I can’t worry about my batting average or whatever. Just score runs.’’

Runs are among the categories in which Betts leads the majors. He is on pace to finish with 166. Ted Williams set the franchise record of 150 in 1949.

“That’s crazy. I can’t do that,’’ Betts said.

Andrew Benintendi, who usually hits second, thinks he could.

“Mookie is going to score a ton of runs. He’s getting on base and he runs the bases so well,’’ Benintendi said. “I feel like if I put the ball in play, he has a chance.’’

Thornburg closing in

Tyler Thornburg believes he could get major league hitters out now. His fastball velocity has steadily been in the mid-90s and he has regained command of his curveball.

“Everything feels good right now,’’ said Thornburg on Saturday before the Red Sox played the Toronto Blue Jays.

At this point, it’s a matter of building up the stamina to pitch on back-to-back days.

“Right now we’re just trying to make sure that when I do come back, I’m not being a detriment to the bullpen,’’ said Thornburg, who is spending the weekend with the Sox before joining Triple A Pawtucket to pitch Monday and Tuesday.

Thornburg has not pitched in a major league game since the end of the 2016 season when he was with the Milwaukee Brewers. The 29-year-old righthanded reliever has pitched in five minor league games on his rehabilitation assignment.

That assignment could run another two weeks.

“I could pitch right now [in the majors]. It’s just a matter of making sure that the recovery is good so we don’t have an issue with how many times I’m pitching,’’ Thornburg said.

Thornburg said his “not-good days’’ are better than they used to be. It’s now more a matter of refining his pitching skills than recovering medically.

“Trying not to rush the process and stay as even-keeled as possible,’’ he said. “I feel like I’ve done a relatively good job of that so far, especially being around the guys and wanting to help.’’

Thornburg had thoracic outlet surgery and had a piece of rib removed. It’s a relatively new procedure for pitchers and results have been mixed.

“There’s been a lot of ups and downs with the guys who have had it,’’ he said. “But I do know a lot of the guys who had it have come back really, really quick, some guys within five or six months.

“I do know at that point there was zero chance I could have pitched in a game. So there are probably different levels of it, different ways to go about it. But I’m glad I took the time.’’

Thornburg has six strikeouts over 4⅓ innings in the minors. But he also has put eight runners on and thrown two wild pitches. How he pitches for Pawtucket this week will determine the next step.

Bradley returns

Jackie Bradley Jr. was back in the lineup after three days off and was 0 for 4 with two strikeouts. The center fielder is 5 of 54 in his last 17 games with 26 strikeouts and is hitting .167.

“OK. Timing off, a little bit late on the front foot. A work in progress,’’ manager Alex Cora said. “We need him to make contact, let’s be honest. I think the rhythm was better but, still, he’s late with the front foot and missing pitches in the strike zone. We’ve got to keep working.’’

Cora said Bradley would start on Sunday.

Bad risk

The Sox had runners on first and second with no outs in the seventh inning when Christian Vazquez tried to steal third base. He was thrown out.

It was the latest foolish base-running mistake by a team that too often seems determined to give away outs.

There was the right intent, at least. Cora said Vazquez went on his own based on advanced scouting information that the Sox could steal third against certain defensive alignments Toronto uses.

“We don’t mind that,’’ Cora said. “But sometimes you’ve got to be smart about it. I don’t think that was the right time for Christian to do that.’’

Said Vazquez: “I thought I had it. But, I know, I should have stayed there.’’

On a roll

Carson Smith picked up two outs in the sixth inning. In his last seven outings, Smith has thrown 5⅔ scoreless innings with no walks and 10 strikeouts. He could soon start to get higher-leverage opportunities . . . The Sox made it official that Dustin Pedroia will start a rehabilitation assignment with Triple A Pawtucket on Monday. The PawSox face Buffalo at 6:15 p.m. at McCoy Stadium. Pedroia has not played for Pawtucket since a two-game rehab assignment in 2010 . . . The coaching staff, which has included Jason Varitek the last two series, put Blake Swihart through an extensive defensive workout behind the plate before the game. When Swihart made throws to second base, Vazquez stood in as the batter and Sandy Leon took the throws . . . Chris Sale has 27 strikeouts and one walk in his last two starts. Through Friday, he was second in the American League with 78 strikeouts . . . Toronto recalled Gio Urshela before the game and started him at shortstop. Dalton Pompey was optioned to Buffalo.
