Sherman Omar Obando Gainor (born January 23, 1970) is a former major league baseball player who played for the Baltimore Orioles and Montreal Expos.

He made his major league debut with the Orioles on April 10, 1993, and ended the season with 3 home runs and 15 RBIs.

An outfielder with power-hitting potential but suspect on defense, he was traded from the Orioles to the Expos for Tony Tarasco during spring training on March 13, 1996.

Obando truly made his mark in his second year, hitting 30 home runs, 101 RBIs, and a .332 batting average despite missing over 30 games due to injuries.

With Ichiro Suzuki gone away to the major leagues, Obando had a good chance at winning the triple crown, but sustained a knee injury that forced him out of over half of the 2001 season.
