Wilbert "Wil" Nieves (born September 25, 1977) is a Puerto Rican former professional baseball catcher and current minor league coach.

He played in Major League Baseball (MLB) for the San Diego Padres, New York Yankees, Washington Nationals, Milwaukee Brewers, Colorado Rockies, Arizona Diamondbacks, and Philadelphia Phillies.

[1] He made his major league debut on July 21, 2002, for the San Diego Padres, and played 28 games with them during their 2002 season.

Nieves won a spot on the Yankees 2007 roster by beating out Todd Pratt and Raul Chavez during spring training.

Joe Torre experimented with using Nieves to help bolster Mussina out of a rough stretch with good results.

[2] Nieves made his first career non-catching appearance in the ninth inning of a game on July 8, 2007, against the Angels; he played first base when the Yankees ran low on position players.

[10] Nieves made the Phillies Opening Day roster in 2014 as the backup catcher to Carlos Ruiz.

He exited the game, and the Phillies recalled catcher Cameron Rupp to serve as Ruiz's backup while Nieves healed.

[1][12] He made the Padres' opening day roster as back-up to catcher Derek Norris after Tim Federowicz suffered a season-ending knee injury during spring training.

[13] Nieves appeared in six games for the Padres in 2015 and collected one hit in thirteen at-bats, an April 12 grand slam against the San Francisco Giants.
