Right-hander Max Scherzer and manager Brad Ausmus called it the biggest out of the Tigers’ 5-2 win over the Angels Saturday.

It was Scherzer’s strikeout of Erick Aybar to end the fourth with runners on second and third.

That out came about in part because of approximately five pitches that Scherzer threw that don’t show up in his pitch count.

When the switch-hitting Aybar stepped in, the Tigers led, 3-1. They had taken the lead on Nick Castellanos’ two-run homer in the second off left-hander C.J. Wilson.

Now, with Aybar up, the Angels had runners on first and third with two out. On Scherzer’s 2-1 pitch — a ball — Ian Stewart tried to steal second. Second-base umpire Quinn Wolcott called him out. The Tigers’ fielders trotted off the field — the inning apparently was over.

But this the Replay Era.

Angels manager Mike Scioscia challenged the out call on Stewart.

Scherzer stayed on the field.

“I didn’t go in the dugout because I did not want to give myself a chance to come down,” he said. “I wanted to stay 100% focused.”

As the umpires wore the headsets and awaited the ruling from the New York command center, Scherzer threw five crucial pitches. They were warm-up pitches.

“I had to take the mentality that it would get overturned and that I had to get Aybar out,” Scherzer said. “I took warm-up pitches to make sure my arm was at 100%. That can be a challenge with delays like that.”

After a few minutes, the call was overturned. The inning was still under way. And Aybar’s at-bat had gotten bigger, because now the potential tying run was on second and a single could tie the game.

Aybar was ahead in the count, 3-1. He took strike two on a change-up, fouled a fastball, then struck out swinging on a change-up.

“He’s a very good fastball hitter, and I thought the change-up was the right pitch,” Scherzer said.

Scherzer said he pitched Aybar the same way as if Stewart had been ruled safe at second originally. The replay delay didn’t allow Scherzer to formulate a different strategy for Aybar.

Although Scherzer didn’t benefit from the delay, he didn’t suffer because of it, either. He assumed the call would be overturned, and he threw those warm-up pitches to stay loose.

Thus did Scherzer, in his third terrific start of the year, achieve his first win following his 21-win season. For the third time this season, he went at least seven innings and allowed two runs or fewer. He’s been in Cy Young form in three starts out of four, even if his 1-1 record doesn’t disclose it.
