Question: Who managed the Giants and won his first and only World Series to tile during his career?
Context: The 1989 World Series was the 86th edition of Major League Baseball's championship series, and the conclusion of the 1989 Major League Baseball season.  A best-of-seven playoff, it was played between the American League (AL) champion Oakland Athletics and the National League (NL) champion San Francisco Giants.  The Series ran from October 14 through October 28, with the Athletics sweeping the Giants in four games.  It was the first World Series sweep since 1976.  The four game sweep by the Athletics at the time would mark only the third time in World Series history that a team never trailed in any game (1963, 1966, and 2004 World Series being the only other times this occurred), and the first in the playoff era (post-1968).  Until 2015, this was the last time a team would win the World Series after losing in the previous year. The Texas Rangers' 2010 season was the 50th in franchise history.  The team, managed by Ron Washington, won their first division title since 1999 and reached the World Series for the first time in only their fourth playoff appearance.  Washington would become only the second manager in franchise history to lead the Rangers to the post season and the first to ever win a post season series.  They would win the American League pennant by defeating the defending World Series champions, the New York Yankees in six games in the ALCS.  In the World Series, they lost to the San Francisco Giants in five games. The 1954 World Series matched the National League champion New York Giants against the American League champion Cleveland Indians.  The Giants swept the Series in four games to win their first championship since , defeating the heavily favored Indians, who had won an AL-record 111 games in the regular season; it has since been broken by the 1998 New York Yankees (114) and again by the 2001 Seattle Mariners (116, tying the 1906 Chicago Cubs for the most wins ever).  The Series is perhaps best-remembered for "The Catch", a sensational running catch made by Giants center fielder Willie Mays in Game 1, snaring a long drive by Vic Wertz near the outfield wall with his back to the infield.  It is also remembered for utility player Dusty Rhodes' clutch hitting in three of the four games, including his walk-off hit for Monte Irvin that won Game 1, probably the best-known hit to be described as a "Chinese home run", since it barely cleared the 258 ft right-field fence at the Polo Grounds.  Giants manager Leo Durocher, who had managed teams to three National League championships, won his first and only World Series title in his managerial career.  After moving West, the San Francisco Giants would not win a World Series until the 2010 season. Pablo Emilio Juan Pedro Sandoval Jr. (born August 11, 1986) is a Venezuelan professional baseball third baseman for the San Francisco Giants of Major League Baseball (MLB).  He has played in Major League Baseball for the Giants and the Boston Red Sox.  He stands 5 ft tall and weighs 255 lb .  He previously played portions of three seasons for the Boston Red Sox and seven seasons for the San Francisco Giants.  Nicknamed "Kung Fu Panda", Sandoval is a two-time All-Star and has won three World Series championships with the Giants.  Sandoval hit three home runs in Game 1 of the 2012 World Series, becoming the fourth person to hit three home runs in a World Series game, and was named the World Series Most Valuable Player (MVP).  During the offseason, he plays for the Navegantes del Magallanes of the Venezuelan Professional Baseball League. The 2015 World Series was the 111th edition of Major League Baseball's championship series, a best-of-seven playoff between the National League (NL) champion New York Mets and the American League (AL) champion Kansas City Royals.  The series was played between October 27 and November 1, with the Royals winning the series 4 games to 1.  It was the first time since the 2010 World Series that the World Series extended into November.  The Royals became the first team since the Oakland Athletics in the 1989 World Series to win the World Series after losing in the previous year.  It was also the first World Series since the 2007 World Series to not feature the Philadelphia Phillies, St. Louis Cardinals, or San Francisco Giants as the NL champions. The Curse of Coogan's Bluff (1958–2010) was a baseball-related superstition that allegedly prevented the San Francisco Giants Major League Baseball franchise from winning the World Series following the club's move from New York City to San Francisco after the conclusion of the 1957 season.  The curse began when upset Giants fans in the New York metropolitan area placed a hex on the relocated franchise.  The curse ended when the Giants won the 2010 World Series in their fourth World Series appearance since the move to San Francisco. The 2014 World Series was the 110th edition of the Major League Baseball (MLB) championship series, a best-of-seven playoff between the National League (NL) champion San Francisco Giants and the American League (AL) champion Kansas City Royals.  The Giants defeated the Royals four games to three to clinch their third World Series championship in a five-season span (2010–14), and their third overall since the club's move to San Francisco from New York.  It was the Giants' eighth World Series championship in franchise history. The 2012 World Series was the 108th edition of Major League Baseball's championship series.  The San Francisco Giants, the National League champions, won the best-of-seven playoff in a 4-game sweep over the American League champions Detroit Tigers.  This marked the Giants' seventh World Series title in franchise history, their second in San Francisco (they won five in New York), and their second in a three-year period (2010–2012).  Their World Series sweep was the first by a National League team since the Cincinnati Reds swept the Oakland Athletics in the 1990 series and the first NL sweep not by the Reds since 1963, when the Los Angeles Dodgers swept the New York Yankees.  The Giants' Pablo Sandoval, who in Game 1 tied a record by hitting three home runs in one World Series game, two off of Tigers' ace Justin Verlander, was named the World Series Most Valuable Player (MVP). Leo Ernest Durocher (July 27, 1905 – October 7, 1991), nicknamed Leo the Lip and Lippy, was an American professional baseball player, manager and coach.  He played in Major League Baseball as an infielder.  Upon his retirement, he ranked fifth all-time among managers with 2,009 career victories, second only to John McGraw in National League history.  Durocher still ranks tenth in career wins by a manager.  A controversial and outspoken character, Durocher had a stormy career dogged by clashes with authority, the baseball commissioner, umpires (his 95 career ejections as a manager trailed only McGraw when he retired, and still rank fourth on the all-time list), and the press. In the 1924 World Series, the Washington Senators beat the New York Giants in seven games.  The Giants became the first team to play in four consecutive World Series, winning in 1921–1922 and losing in 1923–1924.  Their long-time manager, John McGraw, made his ninth and final World Series appearance in 1924.  This was the second extra-inning World Series-deciding game () and the last until .  The winning team of the 1991 World Series was the very same franchise, now known as the Minnesota Twins.
