Question:
The Houston Livestock Show and Rodeo, also called RodeoHouston or abbreviated HLSR, is the largest livestock exhibitions and rodeo in the world. It also includes one of the richest regular-season rodeo events. It has been held at NRG Stadium in Houston, Texas, since 2003. It was previously held in the Astrodome.
One of the largest draws for the Houston Livestock Show and Rodeo is the 20 consecutive evenings of rodeo and concert, held in NRG Stadium. Tickets are relatively inexpensive, averaging about $29 in 2016, and also grant admission to the livestock show and fairgrounds. More than 43,000 season tickets are sold every year, with the remaining seats 30,000 seats available for individual-show sale. Members of the HLSR are given an opportunity to buy individual tickets before the general public.  RodeoHouston is run independently of the Professional Rodeo Cowboys Association (PRCA). It offers one of the largest prize purses in North America, over $2 million, but the winnings do not count towards the competitors' qualification for the PRCA National Finals Rodeo. RodeoHouston is an invitational, featuring 280 of the top professional cowboys. They compete in a playoff format, with the ultimate champion in each event earning $50,000. On the final evening, the rodeo hosts the Cinch SuperShootout. Champions from each of the top 10 rodeos in North America are invited to compete as teams in a subset of rodeo events. The finals and the SuperShoot are televised on Fox Sports.  After the professional rodeo concludes, children are given an opportunity to compete. Each evening, 30 high school students from across the state compete in the calf scramble. They are given the opportunity to chase down (on foot) and catch one of 15 calves, put a halter on them, and drag them back to the center of the stadium. Winners are given money to purchase their own heifer or steer to show the following year. Immediately following the calf scramble is mutton busting. Five- and six-year-olds wearing protective gear try to ride a sheep across a portion of the arena. On the last night of the rodeo, the winners from each of the previous evenings compete again to see who will become grand champion.  A rotating stage is then brought into the arena for the nightly concert. The majority of evenings are performances by country music singers, although several nights are dedicated to pop or rock music. The annual Tejano music night generally draws the largest crowds. The winner of the annual Mariachi Invitational competition is invited to perform onstage with the Tejano acts.

Answer the question at the end by quoting:

Thomson was born in Glasgow, Scotland, the youngest of six children. He arrived in the United States two years later. His father, a cabinet maker, had moved to New York City shortly before Bobby's birth and sent for his family in 1925. Thomson grew up on Staten Island in New York City and signed with the New York Giants for a $100 bonus right out of Curtis High School in 1942.
Thomson became a celebrity for his walk-off home run off Brooklyn Dodgers pitcher Ralph Branca to win the 1951 National League pennant. The home run, nicknamed the "Shot Heard 'Round the World", was dramatic as, until 1969, league pennants were only decided by playoff when the teams involved finished the regular season in a tie. Prior to 1951 playoffs had only been necessary in 1946 (NL) and 1948 (AL).  Although in mid-August the Giants were 13 1/2  games behind the league-leading Dodgers, they won 37 of their final 44 games to tie Brooklyn on the final day of the regular season, forcing a three-game playoff. The Giants won the first game 3-1 as a result of a two-run home run by Thomson (off Branca). Brooklyn's Clem Labine shut out the Giants in the second game, 10-0. The decisive contest, played on October 3 at the Polo Grounds, was the first major sporting event televised coast-to-coast in the United States. The Dodgers took a 4-1 lead into the bottom of the ninth inning; but Giants shortstop Alvin Dark singled, advanced to third on a single by Don Mueller, and scored on a double by Whitey Lockman. With Lockman on second and pinch-runner Clint Hartung at third, Thomson's walk-off home run turned looming defeat into a 5-4 victory. The moment was immortalized by Giants play-by-play announcer Russ Hodges's excited multiple repetitions: "The Giants win the pennant! The Giants win the pennant!"  Waiting in the on-deck circle to hit behind Thomson was rookie Willie Mays. The Giants' season ended, however, at the 1951 World Series; the Yankees swept the last three games to win the best-of-seven series, 4 games to 2. Thomson batted .238 in the Series with no home runs.  The bat from the "Shot Heard 'Round the World" is in the collection of the National Baseball Hall of Fame and Museum in Cooperstown, New York. The uniform worn by Thomson on that day is apparently a part of a large private collection owned by Dan Scheinman, a member of the San Francisco Giants ownership group.

What was Bobby Thomson's role in this?
Thomson's walk-off home run turned looming defeat into a 5-4 victory.
