Ersson, 23 (10/20/99), split the 2022-23 season between the Philadelphia Flyers and the Lehigh Valley Phantoms of the American Hockey League (AHL). The 6-foot-2, 176-pound native of Falun, Sweden, went 24-17-1 with a 2.84 GAA, a .900 SV% and one shutout in 42 games with Lehigh Valley and posted a 6-3-0 record with a 3.07 GAA, a .899 SV% and one shutout in 12 games with Philadelphia. The left-glove backstop made his NHL debut on Dec. 23 at Carolina and earned his first NHL victory Dec. 29 at San Jose. He earned six wins in his first seven NHL starts to become the 12th goaltender in NHL history and second Flyers goaltender (Bob Froese, 1982-83) to win each of his first six career decisions. Ersson stopped all 28 shots faced Jan. 9 at Buffalo to earn his first NHL shutout to become the 14th rookie goaltender in team history to record a shutout, first since Anthony Stolarz on Jan. 29, 2019. He recorded a career-high four-game win streak from Dec. 29-Jan. 9. The four-game win streak ranked T-4th in franchise history for longest road win streak by a rookie goaltender and T-13th among Flyers rookie goaltenders overall.
