Joseph Michael Nathan (born November 22, 1974 in Houston, Texas) is a closer in Major League Baseball who plays for the Minnesota Twins. He bats and throws right-handed, stands at a height of 6 feet 4 inches (1.93 m), and weighs in at 220 pounds (100 kg) as of 2007. He started playing baseball as a shortstop in high school, and played the same position in college. However, he became a pitcher after the San Francisco Giants drafted him in 1995. After working his way through the minor leagues, he alternated between spots in the rotation and the bullpen. He spent a few seasons splitting time between the majors and the minors before having a breakout season as a relief pitcher in 2003. Nathan joined the Minnesota Twins in 2004 as their closing pitcher, and continues to hold that position.
