Matt Mask gets Serhii Kalinichenko again at East vs West 27. The right-arm rematch lands at 105 kg, and that number changes more than the scale.

Kalinichenko won their 2023 meeting 4-2. He took the first three rounds with heavy side pressure and enough arm to keep driving after Mask found some pronation. Yet the match grew less comfortable with every restart. Mask bent the wrist back, settled into the strap, and won two late rounds before Kalinichenko closed the night with another hard sideways attack.

That old result gives Kalinichenko the win. It also gives Mask a very clear place to start.

Mask Has to Finish Through the Hand

The interesting part of the first match came after Kalinichenko lost his wrist. Mask owned more of the hand by round four, but the pin still took work. Kalinichenko kept his arm connected and made every surge toward the pad expensive.

Mask can improve the position without solving the whole problem. His rise and pronation need to open Kalinichenko early, then his back pressure has to keep the shoulder from following. A loose finish gives Kalinichenko time to bring that side pressure back into the round or move toward a press.

Mask just showed better patience in his 4-0 win over Leonidas Arkona. He met open-arm resistance, kept his hand moving, and corrected a rushed finish on the next start. That version of Mask looks better prepared for the exact place where Kalinichenko frustrated him.

The Cut Favors Mask’s Late Rounds

Their first right-arm match belonged to the 115 kg range. The rematch asks Kalinichenko to bring the same arm strength down to 105.

That could sharpen him if the cut goes cleanly. It could also make repeated side-pressure drives harder to sustain. Those attacks won the early rounds in 2023, then Mask began taking the hand once the pace had taken something out of Kalinichenko.

Mask has less distance to travel. He weighed 108.9 kg before East vs West 26, then pulled a much heavier Arkona anyway. The messy weigh-in before that match put Mask in an 11.9 kg hole. He still won every round.

At 105, he finally gets a limit that supports his natural game. Speed matters more when the other man gives away mass, and Mask should arrive with enough endurance to keep attacking the fingers after the first surge.

One Start Can Still Flip the Match

Kalinichenko remains dangerous because his best lane requires very little decoration. If he catches Mask near center and connects his shoulder, the wrist can bend while the arm keeps traveling. Mask felt that exact problem before.

The title talk around this match needs restraint. A future shot at Michael Todd’s current 105 kg game has been floated, but the rematch comes first. Kalinichenko owns the prior right-arm win and knows where Mask struggled.
