Josías Manzanillo Adams (born October 16, 1967) is a Dominican former professional baseball pitcher who played in Major League Baseball (MLB) between 1991 to 2004 for eight different teams.

In 1997, Manzanillo suffered a grisly injury while pitching for the Seattle Mariners.

Not wearing a protective cup, he was struck in the groin by a line drive off the bat of Manny Ramírez which ruptured his testicles.

Manzanillo managed to recover the baseball, throw out Jim Thome at home plate and sprint off the field under his own power before undergoing emergency reconstructive surgery.
