Hermansson authored a four-fight surge between 2018 and 2019, stopping Thales Leites in round three, submitting Gerald Meerschaert with a guillotine, submitting David Branch with a guillotine in round one and outpointing former champion Ronaldo Souza over five rounds in Sunrise, Florida.

His submission grappling, top rides, and pace anchor his 79 Boxing and 83 Wrestling.

Jack Hermansson, the Swede who fights for two flags
Jack Hermansson grew up in Uddevalla, Sweden, and started Greco-Roman wrestling at nine. He moved to Norway at nineteen to find work and began MMA in Oslo, and he fights for both countries. Before the big promotion he held the Cage Warriors and Warrior Fight Series titles, winning the latter with a first-round armbar on Karlos Vemola. His best-known fight may be the win over Thales Leites in 2018, when he was hurt early, survived submission attempts and won by TKO in round three.

Cardio at 88 is why late rounds favor him
Cardio is his top rating at 88 in his 2018 edition. The result that best shows it is the February 2024 win over Joe Pyfer, where he trailed after two rounds and came back to win the final three and a unanimous decision. He also replaced Yoel Romero on short notice in 2019 to beat Ronaldo Souza in a main event. His 2018 and 2020 editions tie at 82 overall, and in the 2020 one BJJ leads at 85 instead.
Kickboxing at 77 is the gap strikers use
Kickboxing is his lowest rating at 77 in the 2018 edition, and it is the lowest in the 2020 one as well at 76. The record has a clear pattern. Santos knocked him out in the first round of their 2017 fight, and Cannonier stopped him in the second round in 2019. If your opponent has a sharp striking game, that is where to expect trouble.
