Q: Question: How many years was Walsh the head coach of the team he went to after the Bengals? Passage 1:On May 7 against the Detroit Tigers, Mark Buehrle pitched a no-hitter through seventh inning before Placido Polanco hit a line-drive double to left field; however the Sox shut out the Tigers 60. On May 11 against the Cleveland Indians in Progressive Field, Carlos Quentin hit a slump after suffering from plantar fasciitis which hampered his swing. He was forced to miss two games as a result of the injury. On May 1518, Sox played with Toronto Blue Jays and Sox lost all four games in Toronto for two straight years and lost 10 straight games in Toronto since June 1, 2007. On May 21 against the Minnesota Twins, the Sox had a biggest loss 201 since May 10, 2002, when Sox lost to Anaheim Angels 190 in Los Angeles. On May 24 against the Pittsburgh Pirates, in the top of the ninth inning, Jack Wilson hit his first home run of season and tied the game at 3. The next batter Nyjer Morgan hit a double and then Delwyn Young singled and Morgan scored from second and Sox trailed it 43. In the bottom of the ninth inning, all batters that Matt Capps faced struck out swinging. The next day in Los Angeles against the Angels, the Sox scored 17 runs in one game, the most runs since the 2006 season. Also on that day, Carlos Quentin suffered his heel injury after he hit a double and he was placed on the 15-day disabled list. The last three games of that month, Sox swept the Royals in Kansas City. The White Sox finished May 1315.
Passage 2:Walsh first developed what would become the West Coast offense when he was offensive coordinator of the Cincinnati Bengals, working under legendary head coach Paul Brown. However, Walsh truly perfected this strategy as the head coach of the San Francisco 49ers. His teams were led by quarterback Joe Montana. Montana, who was noted for his ability to remain calm under pressure, also possessed good mobility and an accurate passing arm. Another important player in the 49ers offense was Roger Craig, a swift, speedy running back who could also catch passes out of the backfield and was a good receiver. Walsh's 49ers teams also featured several All-Pro wide receivers, including Dwight Clark, John Taylor, and Jerry Rice. The 49ers were one of the NFL's powerhouses in the 1980s and 1990s, under the guidance of head coaches Bill Walsh (19791988) and George Seifert (19891996). Walsh won three Super Bowls in the 1981, 1984 and 1988 seasons. Seifert won two Super Bowls in 1989 and 1994. Montana, Walsh and Rice are in the Pro Football Hall of Fame, and so is Montana's successor, quarterback Steve Young. Like Montana, Young was a great running quarterback and a very efficient passer.
Passage 3:Shah Nawaz Bhutto, a direct descendant of Muhammad Khan, came to prominence during the British Raj as a dewan of the princely state of Junagadh in south-western Gujarat in India. During the Partition of India in 1947, the Muslim Nawab of Junagarh wanted to accede his state to the newly created Pakistan, but he faced rebellion by the population of Junagadh, majority of whom were Hindus. The Indian government thwarted Junagadh's accession to Pakistan, and the Bhuttos fled to Sindh in modern-day Pakistan. Shah Nawaz Bhutto moved to Larkana District in Sindh, where his land-ownership made him one of the wealthiest and most influential people in Sindh. Beginning the political dynasty, Shah Nawaz's third son Zulfikar Ali Bhutto (1928-1979) founded the Pakistan People's Party (PPP) in 1967 and served as President and Prime Minister. He married an Iranian-Kurdish woman named Nusrat Bhutto. His daughter, Benazir (1953-2007), also served as Prime Minister, while Benazir's husband, Asif Ali Zardari, later served as president from 2008 to 2013. The Bhuttos continue to dominate the leadership of the PPP. Benazir's son Bilawal Bhutto Zardari became co-chairperson in 2007.
