The Mets' managerial candidates: Buck Showalter, Joe Espada, Matt Quatraro.

Joe Espada, Matt Quatraro and Buck Showalter are the finalists for the Mets’ managerial opening, a source familiar with their process said Sunday.

That trio will interview in person with owner Steve Cohen and others in New York in the coming days, with a hire possible by the end of the week.

The freshly pared list includes one veteran manager (Showalter) and the bench coaches from two of the majors’ most successful teams in recent years (the Astros’ Espada, the Rays’ Quatraro).

Espada and Quatraro, neither of whom has managed in the majors, reportedly also are candidates for the Athletics’ opening. Their status as Mets finalists was first reported by the New York Post.

Espada, 46, overlapped with Mets general manager Billy Eppler during their Yankees days. A frequent participant during managerial searches in recent years, Espada has been Houston’s bench coach for the past four seasons after serving on the Yankees’ and Marlins’ coaching staffs. He also has been a coach for Puerto Rico’s World Baseball Classic teams, including in 2017, when Francisco Lindor and Seth Lugo were on the roster.

Quatraro also has a casual connection with Lindor, having worked as Cleveland’s assistant hitting coach during Lindor’s first three seasons there. He has been the Rays’ bench coach under Kevin Cash for three years. Previously, Quatraro, 48, was a minor-league manager and coach for Tampa Bay. He grew up near Albany.

Showalter, 65, has spent 20 seasons as a major-league manager for the Yankees, Diamondbacks, Rangers and Orioles. He was the AL Manager of the Year in 1994, 2004 and 2014. His clubs had a .506 winning percentage and zero League Championship Series wins (and twice won the World Series in the first year after he left). Since being fired by Baltimore after the 2018 season, Showalter has worked as a broadcaster on MLB Network and the YES Network.

Eppler and other members of the front office conducted the first round of interviews with at least six candidates last week. Also under consideration then were former Angels and Tigers manager Brad Ausmus — whom Eppler hired when he ran the Angels — Dodgers bench coach Bob Geren and Dodgers first-base coach Clayton McCullough.

The Mets’ eventual manager will need to fill out his coaching staff relatively late in the baseball calendar. The only position the Mets have filled is pitching coach, as they retained Jeremy Hefner.
