Thomas Edward John Jr. (born May 22, 1943) is a former pitcher in Major League Baseball whose 288 career victories rank as the seventh highest total among left-handers in major league history. He is also known for the revolutionary surgery, now named after him, which was performed on a damaged ligament in his pitching arm.

John was an outstanding basketball player at Gerstmeyer High School in Terre Haute, Indiana, where he held the city single game scoring record. Choosing baseball when he realized he would not go on to play professional basketball, John signed with the Cleveland Indians and made his major league debut at twenty years-old in 1963. Following two partial seasons with the Indians, John showed occasional excellence during seven respectable years as a starting pitcher with the Chicago White Sox. However, it was a trade before the 1972 season to the Los Angeles Dodgers for mercurial slugger Dick Allen that began a skein of John's most famous years, first with the Dodgers and subsequently with the New York Yankees, where he posted a pair of 20-win seasons and was twice an All-Star. John was also named an All-Star in 1968 with the White Sox and 1978 with LA. He played in all three Yankees vs. Dodgers World Series of his era (1977, 1978 and 1981), having switched over to the Yankees by the time the Dodgers won the Series in 1981.

Joseph Michael Nathan (born November 22, 1974) is an American professional baseball pitcher for the Texas Rangers of Major League Baseball (MLB). Nathan started out his baseball career as a shortstop in high school but converted to a pitcher after being drafted by the San Francisco Giants. He worked his way through the minor leagues, alternating between spots in the rotation and the bullpen. After a few years of splitting time between the majors and the minors, Nathan had a breakout season as a setup man for the Giants in 2003. That off-season, Nathan was traded to the Twins and became their closer.

From 2004 to 2009, Nathan was considered one of the top closers in MLB with four All-Star appearances and a league-leading 246 saves. In 2010, Nathan underwent Tommy John surgery to repair a torn ulnar collateral ligament in his throwing elbow and missed the entire season. On April 3, 2011, Nathan recorded his first save since his injury against the Toronto Blue Jays. On July 16, 2011, Nathan regained his role as closer. On August 10, 2011, Nathan became the Twins all-time leader in saves with 255 in a game against the Boston Red Sox. He signed with the Texas Rangers on November 21, 2011.
