San Jose Sharks (2006–2019)

Pavelski during a game in the 2007–08 season.

Pavelski began his NHL career in the 2006–07 season. He began on a hot streak, scoring a goal in his first game, and scoring 7 goals and 10 points in his first 12 games. Pavelski earned the nickname "Little Joe" from Sharks announcer Randy Hahn, a reference to Pavelski's teammate and San Jose superstar "Jumbo Joe", Joe Thornton.^[11]

During the 2007–08 season, Pavelski became a regular player on the Sharks roster and one of the best and most consistent young players on the squad, playing in all 82 regular season games and in all 13 2008 Stanley Cup playoff games. He also became one of the most effective players in the NHL during shootouts, scoring 7 times on 11 opportunities that season. During the 2008 playoffs, he was tied with Ryane Clowe for the team lead in goals (five) and tied for second with Clowe in points (nine). Pavelski also led San Jose with three game-winning goals during the playoffs, which tied for third most in the playoffs overall. In addition to his offensive numbers, he finished tied 12th among NHL forwards in blocked shots (59) during the regular season.^[12]

Pavelski had another solid season in 2008–09, playing in 80 games and recording 25 goals and 34 assists for 59 points, career-highs for all three statistics at the time.

During the 2010 playoffs, Pavelski had three-straight multi-goal games (Game 6 against the Colorado Avalanche and Games 1 and 2 against the Detroit Red Wings), not only helping the Sharks win all three games, but also becoming the first player to do so since Mario Lemieux in 1992. It was after this streak that he also picked up the nickname "The Big Pavelski" to accompany his nickname of "Little Joe".

Pavelski came close to scoring his first NHL hat-trick on March 19, 2011, against the St. Louis Blues. After the game, however, one of the goals was awarded to Patrick Marleau, when it had been originally attributed to Pavelski.^[13]

During the 2012–13 NHL lockout, Pavelski signed with Belarusian team Dinamo Minsk of the Kontinental Hockey League (KHL).^[14]

On July 30, 2013, the Sharks announced that Pavelski had signed a new five-year contract with the team effective from the 2014–15 season through to the 2018–19 season.^[15]

On March 11, 2014, against the Toronto Maple Leafs, Pavelski scored his 400th career NHL point.^[16] During the season, Pavelski recorded a career-high 41 goals and 79 points.^[17]

During the 2014–15 season, Pavelski had another strong offensive season, scoring 70 points (37 goals and 33 assists)^[18] and was named one of the Sharks' four alternate captains.

On October 5, 2015, Pavelski was named the Sharks' ninth captain in history, over teammates (and former Sharks' captains) Joe Thornton and Patrick Marleau.^[19][20]

Pavelski in December 2016.

During the 2015–16 regular season, Pavelski tallied 78 points (38 goals and 40 assists) and he earned a spot in the 2016 NHL All-Star Game. He finished fifth in the NHL in goals with 38, sixth in points and first in game-winning goals with 11. Pavelski's success continued into the 2016 playoffs, as he led the Sharks into their first ever Stanley Cup Finals. Pavelski only scored one goal in the Finals, though he still finished as the playoff leader in goals (14) and finished third in points (23).^[18]

From 2013 to 2016, Pavelski scored the second-most goals in the NHL with 116 and second-most power play goals with 47, behind only Alexander Ovechkin in both categories.^[21]

On December 1, 2017, Pavelski scored his 300th NHL goal on a pass from Joe Thornton against the Florida Panthers.^[22] He became only the second Sharks player to score 300 goals with the team, Patrick Marleau.^[23]

On April 23, 2019, during the 2019 playoffs, Pavelski suffered a major head injury after a cross check from Vegas Golden Knights center Cody Eakin, followed immediately by an incidental collision with Vegas' Paul Stastny which knocked Pavelski awkwardly to the ice.^[24] Pavelski was helped off of the ice and did not return to the game. Eakin was charged with a five-minute major penalty and a ten-minute game misconduct,^[25] which enabled the Sharks to score four goals in five minutes and send the game to overtime. The Sharks later won the game 5–4 in overtime and advanced to the second round of the playoffs.^[26]

On July 1, 2019, as an unrestricted free agent, Pavelski signed a three-year, $21 million contract with the Dallas Stars.^[27] On August 16, 2020, during the Stanley Cup playoffs, Pavelski scored the first postseason hat-trick in Stars history since their relocation from Minnesota; Dino Ciccarelli (twice), Steve Payne and Bob Brooke had previously scored playoff hat-tricks for the North Stars.^[28] On September 26, 2020, in game 5 of the 2020 Stanley Cup Finals against the Tampa Bay Lightning, Pavelski scored his 61st playoff goal against Tampa Bay goaltender Andrei Vasilevskiy, surpassing Joe Mullen (who has 60 playoff goals) as the all-time playoff goal scorer by a United States-born player. Pavelski and the Stars would go on to lose the series 4-2.

Pavelski was named an alternate captain for the 2021–22 season and has played on the Stars' top-line, alongside young guns Roope Hintz and Jason Robertson.^[29] That top-line led the Stars in scoring, accounting for almost 44% of the Stars’ goals.^[30] Given the age difference between Pavelski and his linemates (12 and 15 years), the line became known as the "Pavelski and Sons" line in the Dallas sports media. On November 26, 2021, he scored his 400th NHL goal, making him the tenth American-born player to do so.^[31] On March 11, 2022, the Stars signed Pavelski to a one-year, $5.5 million contract.^[32] He would go on to enjoy a highly productive output during the 2021–22 season, scoring 27 goals with 54 assists for a career-best 81 points in the season in all 82 games played.

On January 1, 2023, the Stars signed Pavelski to a one-year, $3.5 million extension.^[33] Pavelski scored his 1,000th career point in a 6-1 win over the Detroit Red Wings with a goal on goaltender Ville Husso on April 10, 2023.^[34]
