The more the merrier.

Two additional names emerged Friday in the Mets’ managerial search, bringing the number of known candidates to eight in the team’s search for Mickey Callaway’s successor.

Tim Bogar, a former Mets infielder who serves as the Nationals’ first-base coach, will receive a face-to-face interview with team brass. Also, Padres first base coach Skip Schumaker interviewed with team officials in recent days. Both candidacies were confirmed by The Post’s Joel Sherman.

The 52-year-old Bogar, who played for the Mets from 1993-96, has a working relationship with assistant general manager Allard Baird from their time together in Boston. Bogar spent 22 games as interim manager for the Rangers in 2014 following Ron Washington’s resignation and previously was the bench coach in 2012 for Boston, where he had a contentious relationship with manager Bobby Valentine, who was fired after one season.

Schumaker, 39, played for the Cardinals, Dodgers and Reds over an 11-year major league career. He just concluded his second season as a coach with the Padres. As a player, Schumaker was a client of GM Brodie Van Wagenen’s with CAA.

Joe Girardi, Carlos Beltran, Luis Rojas, Mike Bell, Derek Shelton and Eduardo Perez are the other known candidates for the Mets’ vacancy. Girardi is a finalist for the Phillies job — he reportedly will receive a second interview with the team on Monday — and has also met with the Cubs.

An industry source said it’s possible the Mets will begin callback interviews in the coming days. It’s unclear at this point if any of the candidates have met with owner Fred Wilpon, who presumably would have to give his blessing on Van Wagenen’s recommendation for the job. When Callaway was selected two years ago, the Mets skipped the callback round of interviews because of concerns the Phillies would beat them in hiring the former Indians pitching coach.

Girardi is the only member of the group who owns major league managing experience, as the Mets have cast a wide-ranging search over the past two weeks. Beltran, a Yankees special assistant, has indicated he only wants to be considered for the Mets’ opening, saying he turned down opportunities to interview with other clubs.

In addition to the Mets, Cubs and Phillies, the Padres, Giants, Pirates and Royals are searching for new managers. The Angels are the only team to have filled a vacancy with the hiring of Joe Maddon on Wednesday.

The Mets’ most outside-the-box candidate might be Perez, an ESPN analyst who has spent the past six years removed from the dugout — he was the Astros’ bench coach in 2013. Rojas, who served as the Mets’ quality control coach this season, is the only known internal candidate.

The Mets have given first base coach/catching instructor Glenn Sherlock permission to pursue other jobs. Sherlock’s contract expires at the end of the month, and he isn’t guaranteed a spot on the next coaching staff. Previously, the Mets informed bench coach Jim Riggleman that his contract won’t be renewed for next season. Sherlock spent the past three seasons with the Mets.
