Like all the times that Mets players have been hit by pitches through the first three weeks of the season, this news didn’t sit well with Buck Showalter either.

The Mets’ manager was stunned that Cardinals first-base coach Stubby Clapp wasn’t suspended for his role in the teams’ skirmish on Wednesday in St. Louis. He asked reporters what discipline the Cardinals received, and expected Clapp to have been given a suspension of some kind, which he did not.

“Nothing? Really?” an exasperated Showalter said Friday before the Mets’ 3-0 win over the Phillies at Citi Field. “Okey dokey.”

Clapp tackled Pete Alonso to the ground in the middle of the melee after both benches cleared following an up-and-in fastball from Mets reliever Yoan Lopez to Cardinals third baseman Nolan Arenado. The pitch was believed to be in retaliation for J.D. Davis getting plunked on the foot/ankle area in the previous inning.

Arenado and Cardinals pitcher Genesis Cabrera each received suspensions. Arenado was given two games and Cabrera one.

The Mets have been hit a league-high 19 times in 20 games to begin the season.

Earlier in the day, the Mets met with MLB representatives to discuss the rash of pitches that have hit their players this year. Former pitcher Dan Otero came along with MLB executive vice president of baseball operations Morgan Sword to talk about the issue.

“Lot of good give and take,” Showalter said.

Entering the final weekend before the Mets might have to make a difficult decision on his future on the roster, Robinson Cano returned to the starting lineup.

The struggling 39-year-old heard boos after striking out in his first two at-bats before he was thrown out at second while trying to stretch a single into a double in the seventh inning. Cano served as the DH and batted sixth in his first start since Monday.

“I didn’t want Robbie to get too far away from playing,” Showalter said.

Cano, who was suspended for all of last season after testing positive a second time for performance-enhancing drugs, ended Friday with a .501 OPS and had started 11 of the Mets’ first 21 games. His future remains uncertain. He has two years and $40.5 million left on his contract, but the Mets will need to trim two players from their 28-man roster by Monday, with a release of Cano among the potential avenues to get to 26.

Davis left St. Louis on Wednesday in a boot, but had a better prognosis by Friday.

After Davis was hit in the left foot by a pitch that forced him out of the game Wednesday, he was available off the bench Friday, but didn’t play.

“He may have dodged a … potential injury,” Showalter said. “We’ll see. So far, so good. There wasn’t a need for more imaging. He’s improved.”
