Example Input: Question: Who was the other finalist in the 1930 Allan Cup other than the team Roche was on? Passage:Roche was born in Prescott, Ontario, but moved to Montreal where he played junior hockey for the Montreal Victorias and other teams. He moved up to senior hockey for the Montreal Hockey Club and played for their Allan Cup-winning squad of 1930. He signed with the Maroons of the NHL, playing for the Maroons and the Windsor Bulldogs until 1933. He was released by the Maroons and signed with the Bruins in January 1933 only to be traded to the Senators one month later. In his one full season with the Senators in 1933–34 he showed a scoring touch, scoring 13 goals and 16 assists in 45 games. The next season, the Senators relocated to St. Louis to become the Eagles. Roche was traded twice in 1934–35; from St. Louis to Buffalo, then to the Red Wings. That marked his last season in the NHL, as he subsequently played for various minor-league pro teams until 1942.

Example Input: Question: Who was the manager for Boston Red Sox when Travis hit a infield single for the Blue Jays? Passage:In late April 2016, Travis began taking part in extended spring training games. He was assigned to the Advanced-A Dunedin Blue Jays for rehab on May 13. On May 18, he was promoted to the Triple-A Buffalo Bisons to continue rehabbing. On May 25, Travis was activated off the disabled list by the Blue Jays and called up. He hit a walk-off infield single on May 28 to help the Blue Jays defeat the Boston Red Sox 10–9. On August 5, Travis hit two home runs in a game for the first time in his career. Leading off against the Kansas City Royals, Travis hit a solo home run to give the Blue Jays an early 1–0 lead. In the ninth inning, he hit another solo home run off Kelvin Herrera to lift Toronto to a 4–3 victory. On August 8, Travis hit his first career triple, which came as part of a four-hit game against the Tampa Bay Rays. Following a game on August 31, the Blue Jays optioned Travis to the Rookie-Advanced Bluefield Blue Jays. The move was made to allow Josh Thole to be re-signed and have postseason eligibility. As the Bluefield season would end on September 1, Travis could be immediately recalled by Toronto afterward, bypassing the ten-day waiting period. Travis was recalled by the Blue Jays on September 2. He finished the season hitting .300 with 11 home runs and 50 RBI in 101 games. Travis played in the Wild Card Game and the first game of the American League Division Series, but missed the remainder of the ALDS with a bone bruise in his right knee. He played in the first game of the Championship Series, but left in the fifth inning after reaggravating his knee injury. On October 15, Travis was removed from the ALCS roster due to injury, and replaced by Justin Smoak. In accordance with MLB rules, Travis was ruled ineligible to return for the postseason, ending his season. On November 18, he underwent right knee surgery to remove a small flap of cartilage, and was expected to be ready for spring training.
