On April 18, three weeks remained on Aroldis Chapman’s 30-day suspension for violating MLB’s domestic violence policy.

Dellin Betances and Andrew Miller were dominating hitters with ease and people were wondering how much better Chapman’s return would make the Yankees’ late-inning bullpen.

On that mid-April day, former Yankees reliever Mike Stanton said the potential for mind-boggling strikeout totals existed.

“I don’t remember a bullpen with the potential to have this many strikeouts,’’ Stanton said. “When Chapman gets back you could have 300 strikeouts between the three.’’

Chapman has been back since May 9. The Yankees have played 43 games. Combined, the Holy Trinity of Smoke has struck out 82 batters in 46 innings. At that pace they would register 321 punchouts.

In 20 ¹/₃ innings, Betances has whiffed 40 with a combination of high-90s gas and a knee-buckling breaking ball. Miller has worked 18 ²/₃ frames and fanned 33 thanks to a wipeout slider. Then there is Chapman, easily the most exciting of the three because he consistently pushes speed guns into triple digits. In seven innings, he has fanned nine.

“We need the starters to go deep some days because we cannot use those three guys every single day because it’s unfair for those three guys in the bullpen to put them in the game day after day,’’ Carlos Beltran said. “We have to find a way to give those guys a break.’’

Betances, Miller and Chapman have worked together in five games with Chapman posting five of his six saves following Miller.

Alex Rodriguez returns from the disabled list Tuesday night and will face a pitcher he has had success against in Blue Jays knuckleballer R.A. Dickey. Rodriguez is 10-for-33 against him with a homer and three RBIs.

Mark Teixeira mentions his recent slump is related to a timing problem hitting from the left side. What is most alarming about Teixeira this season is that he has fanned 44 times compared to 28 hits.

That’s puzzling for a hitter who, counting this season’s numbers, has 1,811 hits against 1,380 Ks for his career.

Teixeira’s last homer was April 13 and he has gone 123 at-bats without hitting a ball over the wall. He did snap a 0-for-19 slide with an RBI infield single in Sunday’s 5-4 victory over Oakland that plated Brett Gardner from second.

Teixeira’s right knee is wrapped in ice after games, but he hasn’t admitted there is a problem that might be hindering him at the plate, where he is batting .193 (28-for-145) and hasn’t had an extra base hit in the past six games.

While Beltran’s hot streak has carried the Yankees, Jacoby Ellsbury has shown how important it is that he stays on the field.

Since returning to the starting lineup from a right hip problem that cost him seven games on May 14, Ellsbury is hitting .355 (11-for-38) and the Yankees are 6-2 during that stretch.
