At the start of the 2008–09 season, on October 8, 2008, Sharp was named an alternate captain for the Blackhawks, along with Duncan Keith. Despite being limited by injuries, Sharp helped the Blackhawks form a highly offensive and young core led by second-year forwards Jonathan Toews, Patrick Kane and newly acquired defenceman Brian Campbell. He finished the season with 44 points in 61 games. He added 11 points in the 2009 playoffs as the Blackhawks were eliminated in the Western Conference Finals by the Detroit Red Wings. On June 9, 2010, Sharp won the Stanley Cup with Chicago over the Philadelphia Flyers, his former team. He contributed 11 goals and 11 assists during Chicago's 2010 playoff run. On January 30, 2011, Sharp was named the Most Valuable Player in the 2011 NHL All-Star Game, earning one goal and two assists in the game. On August 3, 2011, he signed a new five-year contract with Chicago worth $29.5 million, which came into effect for the 2012–13 season and carried an annual salary cap hit of $5.9 million. On September 12, 2011, Sharp underwent an emergency appendectomy after experiencing abdominal discomfort. Team physician Dr. Michael Terry anticipated that Sharp would have a full recovery in about three-to-four weeks. On November 25, 2011, in a 6–5 win against the Anaheim Ducks, Sharp scored his second career NHL hat-trick. Jonathan Toews, who himself had a career-high five-point game, recorded the primary assists on all three of Sharp's goals. Sharp would finish the season with 33 goals and 36 assists. He scored one goal during the Blackhawks' first round exit to the Phoenix Coyotes in the 2012 playoffs. During the 2012–13 NHL lockout, Sharp remained in Chicago, while many of his teammates started playing for European leagues. He spent time with his then nine-month-old daughter, and was involved in Gillette's "My City is My Gym" fitness program as a spokesperson. During the shortened NHL season, when play resumed in 2013, Sharp played 28 games, recording 6 goals and 14 assists and a plus-minus rating of +8. On December 27, 2013, in a 7–2 win against the Colorado Avalanche, Sharp scored his third career NHL hat-trick. Four games after, in a 5–3 win against the New Jersey Devils on January 3, 2014, he scored his fourth NHL hat-trick. On January 7, 2014, he was named to the Canadian Olympic team for the 2014 Winter Olympics in Sochi.
