PITTSBURGH — Dylan Guenther scored 42 seconds into overtime and the Utah Mammoth rallied to beat the Pittsburgh Penguins 5-4 on Sunday.

Guenther, who has five goals in his last four games, beat Sergei Murashov with a wrist shot from the slot. Utah won its second straight following a three-game losing streak.

Michael Carcone scored twice for Utah, while Nate Schmidt and Sean Durzi also added third-period goals, as the Mammoth briefly pulled ahead, 4-3, after trailing 3-0 entering the final 20 minutes.

Karel Vejmelka made 12 saves.

Justin Brazeau scored twice for Pittsburgh and Bryan Rust scored in his third straight game. Ben Kindel also scored on a breakaway and added two assists.

Sidney Crosby’s four-game point streak ended and he remains within two of tying Hall of Famer Mario Lemieux’s franchise record for career points.

Kris Letang had an assist to pass Hall of Famer Borje Salming for the 21st-most points by a defenseman in NHL history.

Murashov finished with 32 saves.

Pittsburgh earned a point for the ninth time in 11 games, but the Penguins lost their fifth straight. The Penguins, who are 1-9 in overtime, blew a 5-1 third-period lead against San Jose on Saturday and lost to Anaheim earlier this week after the Ducks forced overtime with one-tenth of a second left.

Utah needed just six minutes to erase a three-goal deficit and take a brief third-period lead.

Schmidt scored off a rebound at 1:07 of the third and Carcone scored his first goal at 1:22 when he banked his own rebound off Murashov’s back. Durzi tied the game at 5:35 on a shot through traffic. Pittsburgh challenged it for goaltender interference. When the goal was upheld, Carcone gave the Mammoth a 4-3 lead with a power-play goal on a one-timer from the right circle.

Brazeau tied it at 14:06 when he tipped Erik Karlsson’s point shot behind Vejmelka.

Pittsburgh played again without goaltender Stuart Skinner and defenseman Brett Kulak, who were acquired Friday from Edmonton in a trade for Tristan Jarry and Sam Poulin. Skinner and Kulak were granted non-roster status to settle the immigration process.

Saturday’s game

John Klingberg capped off a frantic late rally by scoring his second goal of the game 2:57 into overtime to lift the San Jose Sharks to an improbable 6-5 victory over the Penguins on Saturday.

Klingberg’s seventh of the season off a feed from Macklin Celebrini gave the Sharks their first victory in the franchise’s 34-year history when trailing by four goals in the third.

San Jose trailed 5-1 with less than 14 minutes to go. Klingberg and William Eklund scored to get the Sharks back in it, and Celebrini and Tyler Toffoli beat Pittsburgh goalie Arturs Silovs with the goaltender pulled to force overtime.

Toffoli, whose tying goal came with 1:38 to play, finished with two goals and two assists. Celebrini had a goal and two assists to push his season point total to 44.

Yaroslav Askarov withstood a second-period deluge from Pittsburgh and finished with 38 saves as San Jose finished a five-game road trip at 3-2.

Crosby scored a goal and added an assist. Crosby beat Askarov in the first period for his 19th goal of the season and assisted on Bryan Rust’s power-play goal in the second to push his career point total to 1,721.

Kevin Hayes, Rutger McGroarty and Anthony Mantha also scored for the Penguins. Rickard Rakell played 22:12 in his return from a 20-game absence due to a hand injury. Silovs stopped 26 shots as Pittsburgh dropped its fourth straight.

The loss marked the first time the Penguins blew a four-goal lead in the third period since March 10, 1976.
