Question: What age bracket plays for the Real Madrid's youth system? Passage:Casillas began his career in Real Madrid's youth system, known as La Fábrica, during the 1990–91 season. On 27 November 1997, at age 16 and still a junior, he was first called up to the senior team squad to face Rosenborg in the UEFA Champions League, although he remained on the bench throughout. After spending a season with the C-team in the fourth tier, during which they won their regional group, he came into contention as the club's first-choice between the posts. In starting the 1999–2000 UEFA Champions League group stage fixture against Olympiakos on 15 September 1999, he became the youngest goalkeeper ever to feature in the competition at the time, aged 18 years and 177 days; a record which was only broken in October 2017 by Mile Svilar. Three days earlier, Casillas had made his La Liga debut in a 2–2 draw against Athletic Bilbao at San Mamés Stadium. In May 2000, he became the youngest ever goalkeeper to play in and win a Champions League final when Real Madrid defeated Valencia 3–0, just four days after his 19th birthday.

Question: In what year was the person born who won the 1969 Rookie of the Year? Passage:The Royals began operations with General Manager Cedric Tallis, who soon developed a reputation as the best trader in the league. The first big trade was with fellow expansion team Seattle, which brought in 1969 Rookie of the Year Lou Piniella. In their inaugural game, on April 8, 1969, the Royals defeated the Minnesota Twins 4-3 in 12 innings. Two pitching stars from the Baltimore Orioles team that won the 1966 World Series pitched for the Royals in the inaugural game: Wally Bunker threw the franchise's very first pitch, and Moe Drabowsky won the game in relief. After finishing the season in 5th place, the Royals' next trade cemented a reputation as a speedy team. Third baseman Joe Foy was traded to the New York Mets for speedy outfielder Amos Otis, who would become the Royals' first star. Further one-sided trades brought to the Royals second baseman Cookie Rojas, bullpen ace Ted Abernathy, shortstop Fred Patek, first baseman John Mayberry and left fielder Hal McRae. The Royals also invested in a strong farm system and in the early years developed such future stars as pitchers Paul Splittorff and Steve Busby, infielders George Brett and Frank White, and outfielder Al Cowens.
