Eugene Macalalag "Geno" Espineli (born September 8, 1982) is an American former Major League Baseball relief pitcher for the San Francisco Giants.

When Espineli made his debut with San Francisco on July 23, 2008, with 0.2 innings of perfect relief against the visiting Washington Nationals, many believe he became the first full-blooded Filipino to ever play in the major leagues.

[1] Espineli signed a minor league contract with an invitation to 2011 spring training with the Colorado Rockies.

Eugene is currently the first and only full-blooded Filipino playing for the Dirtbags in the world renowned Denver NABA league.
