Question: Question: How long had the Atlanta Braves been a team when the Mets swept them in a National League Championship Series? Passage:The Mets went on to sweep the Atlanta Braves in the 1969 National League Championship Series, but were heavy underdogs heading into the 1969 World Series against the Baltimore Orioles. Following a 4-1 loss in the series opener with Cy Young award winner Seaver on the mound, it seemed as if the Mets had little chance against the Orioles. However, the Mets bounced back, winning the next four games to capture their first world championship. Besides catching every inning in the post-season, Grote contributed offensively with a single in Game Two to keep a ninth inning rally alive and Al Weis followed with the game-winning hit. With Game Four tied, Grote doubled to start the tenth inning, then pinch runner Rod Gaspar scored the winning run when an errant throw hit J.C. Martin on the wrist. With Grote calling the pitches, the Mets pitching staff held the Orioles hitters to a .146 batting average during the series.

Question: Question: Which of Shapovalov's opponents at Gatineau and Drummondville was younger? Passage:In March in Gatineau, Shapovalov captured his fourth ITF Futures singles title after defeating Gleb Sakharov in straight sets. Two weeks later, he won his first ATP Challenger title with a victory over Ruben Bemelmans at the 75K in Drummondville, and was the youngest Canadian to win a Challenger until Félix Auger-Aliassime's victory at the Open Sopra Steria de Lyon later in the year. The next week, he was defeated by Mirza Bašić in the final of the ATP Challenger 50K in Guadalajara, stopping his winning streak at 17 matches. At the French Open in May, his first professional Grand Slam, he was defeated in the first round of qualifying by the first seed Marius Copil in three sets. In June, Shapovalov qualified for the ATP 500 at the Queen's Club Championships, his fourth ATP main draw but his first as a qualifier. In the first round, he defeated his second top 50 player, world No. 47 Kyle Edmund, before losing to world No. 14 Tomáš Berdych. At Wimbledon in July, Shapovalov was awarded a wild card for the main draw. He was defeated by Jerzy Janowicz in the opening round. At the end of the month, he won his second ATP Challenger title, defeating compatriot Peter Polansky in the final of the 75K in Gatineau.

Question: Question: Who was the leader of Yugoslavia in 1923? Passage:In 1923 it was organised the first edition of leagues in the Kingdom of Yugoslavia where, beside the top-level national Yugoslav Football Championship, regional championships were also played. The clubs of the Drina Banovina, part of Littoral Banovina and Vrbas Banovina, territorially similar to present day Bosnia and Herzegovina, played within the Sarajevo Football Subassociation League until 1939. The champions of Subassociation Leagues were granted a place in the qualifiers to the Yugoslav Championship, a top national level. SAŠK (1923, 1924, 1925, 1926, 1927, 1928, 1930/31), Slavija (1929, 1930, 1932/33, 1934/35, 1935/36, 1936/37, 1937/38, 1938/39, 1939/40), FK Krajišnik Banja Luka (1935/36) were the clubs to manage to participate in the national league, first in 1923 when the championship was played in a cup system. In 1939 the Yugoslav league system was changed, with the creation of separate Serbian and Croato-Slovenian Leagues which will serve as qualifying leagues for the final phase of the Yugoslav Championship. The clubs from the Sarajevo Subassociation played their qualifications to the Serbian League, however Slavija Sarajevo managed to participate, in 1939–40 (3rd place) and 1940–41 (9th place) and played their qualifications to the Croatian-Slovenian League, however SAŠK managed to participate, and it did it in both occasions, in 1939–40 (5th place) and 1940–41 (5th place). That became the last season before the beginning of the Second World War.
