Question: What nationality was the professional baseball pitcher who was in the 111th edition of Major League Baseball's championship series

<P0-S0> The World Series, the modern championship series of Major League Baseball, began in 1903, and was established as an annual event in 1905. <P0-S1>  Before the formation of the American Association (AA), there were no playoff rounds—all championships went to the team with the best record at the end of the season. <P0-S2>  In the initial season of the National League (NL) in 1876, there was controversy as to which team was the champion: the Chicago White Stockings, who had the best overall record (52–14), or the St. Louis Brown Stockings (45–19), who were the only team to have a winning record against every other franchise in the league. <P0-S3>  The teams agreed to play a five-game "Championship of the West" series, won by St. Louis, 4 games to 1. <P0-S4>  Beginning in 1884, the championship series between the National League and the American Association were promoted and referred to as the "World's Championship Series" (WCS), or "World's Series" for short; however, they are not officially recognized by Major League Baseball as part of World Series history. <P0-S5>  Though early publications, such as Ernest Lanigan's "Baseball Cyclopedia" and Turkin and Thompson's "Encyclopedia of Baseball", listed the 19th-century games on an equal basis with those of the 20th century, "Sporting News" publications about the World Series, which began in the 1920s, ignored the 19th-century games, as did most publications about the Series after 1960. <P0-S6>  Major League Baseball, in general, regards 19th-century events as a prologue to the modern era of baseball, which is defined by the emergence of the two present major leagues. <SEP> <P1-S0>  The series was played between October 27 and November 1, with the Royals winning the series 4 games to 1. <P1-S1>  It was the first time since the 2010 World Series that the World Series extended into November. <P1-S2>  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. <P1-S3> 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. <P1-S4>  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. <SEP> <P2-S0> Wade Allen Davis (born September 7, 1985) is an American professional baseball pitcher for the Chicago Cubs of Major League Baseball (MLB). <P2-S1>  He previously played for the Tampa Bay Rays and Kansas City Royals. <P2-S2>  Davis is a three-time MLB All-Star. <P2-S3>  He was a member of the Royals' 2015 World Series-winning team, and earned the Babe Ruth Award for his performance in the 2015 MLB postseason. <SEP> <P3-S0> The 1987 World Series was the 84th edition of Major League Baseball's championship series, and the conclusion of the 1987 Major League Baseball season. <P3-S1>  It was a best-of-seven playoff played between the American League (AL) champion Minnesota Twins and the National League (NL) champion St. Louis Cardinals. <P3-S2>  The Twins defeated the Cardinals four games to three to win the Series. <P3-S3>  Twins pitcher Frank Viola was named as the 1987 World Series MVP.
