The final audition is set.

After coming through his 30-pitch live batting practice session Tuesday feeling healthy, Zack Wheeler is “penciled in” to start Friday against the Pirates in his return from the injured list, according to manager Mickey Callaway. The right-hander has not pitched since July 7 after experiencing a right shoulder impingement and landing on the IL July 15.

“Zack is feeling good and he’s penciled in for Friday at this moment,” Callaway said Wednesday before the Mets’ 7-2 loss to the Padres, confirming it publicly for the first time. “We’re excited he’s going to be out there on the mound again.”

All eyes will be on Wheeler, who is the Mets’ top trade chip among their impending free agents, assuming he is fully healthy. He will likely be on a pitch count of around 75-85 pitches as interested teams get one last look before next Wednesday’s trade deadline.

Jeurys Familia was booed off the mound again Wednesday night after recording just a single out (on a caught stealing) in the eighth inning. He was tagged for two runs on two hits and a walk as his ERA rose to 7.36.

In his previous appearance, Familia walked two batters without recording an out Sunday in San Francisco, though he had been better in his five outings before then. Callaway insisted his stuff still looked “great.”

“Sometimes you sit there and you scratch your head,” Callaway said.

Wednesday marked a year since Jeff McNeil made his major league debut. Since then, he has hit .337 in 150 games — trailing only Christian Yelich (.345) during that span — and his .342 average this season leads the National League.

“He’s been hitting the ball ever since he came up a year ago,” Callaway said of McNeil, who went 1-for-3 with a double and a walk. “But there’s no doubt he’s evolved as a Major League Baseball player. His ability to play multiple positions, do it comfortably, do it at an elite level, in my opinion, has been uncanny and quite a surprise to all of us.

“It’s been pretty special to watch for a year. Everybody in our organization knew this kid could hit when he was healthy down in the minor leagues, but you couldn’t ever expect this.”

McNeil has ventured away from just the infield this year, adding the corner-outfield spots to his repertoire. But his bat has made the most noise, landing him in on the NL All-Star team and in the chase for a batting title.

“This guy hits like Pete Rose , Wade Boggs , Ichiro ,” Callaway said. “It’s unbelievable and he continues to do it.”

Pete Alonso will receive his $1 million check on Friday for winning the Home Run Derby. In turn, he will present checks to the Wounded Warrior Project and the Tunnel to Towers Foundation, with 5 percent of his winnings going to each organization.
