UFC Poland results - Calderwood armbarred by Moroz in stunner, Manuwa beats Blachowicz

The UFC women's strawweight division got a huge shake-up on the main card, while Jimi Manuwa and Jan Blachowicz tangled in an important co-main event in the light heavyweight division. Here are the results from the first 3 main card fights on UFC Fight Night: Cro Cop vs. Gonzaga 2 in Krakow, Poland.

Maryna Moroz (6-0 MMA, 1-0 UFC) def. Joanne Calderwood (9-1 MMA, 1-1 UFC) via submission (armbar) at 1:30 of round 1  - Women's Strawweights

The opening fight of the main card produced far and away the biggest upset, as Ukraine's Moroz hurt Calderwood with her boxing and then pulled guard for her preferred armbar, which she was able to get with relative ease. Moroz then called out reigning champion Joanna Jedrzejczyk, much to the dislike of the Polish crowd. Calderwood looked completely overmatched for such a big favorite, and Moroz just became a new contender in the new UFC women's 115 lbs division.

Pawel Pawlak (11-1 MMA, 1-1 UFC)  def. Sheldon Westcott (8-3-1 MMA, 0-2 UFC) by unanimous decision (29-28 x3) -  Welterweights

Westcott and Pawlak primarily fought in close quarters, clinched against the fence and tangling themselves in a wrestling struggle. Sheldon was the superior wrestler but never really maintained positional dominance. Westcott did well to throw strikes on Pawlak was he got back to his feet but otherwise round 1 wasn't too action-packed. Pawlak came out strong in the 2nd round with a big knee to the body and then another one to the head that momentarily dropped the Canadian. Westcott showed signs of tiring when he had Pawlak in a body lock but couldn't complete takedowns and ended up getting reversed or separated.

Pawlak was briefly taken down in the 3rd after rocking Westcott with a hard right hand, but Pawlak got back up and hit a beautiful throw on the Canadian that put him on his back. The Polish faithful cheered Pawlak on as he advanced his position and landed some ground-and-pound before going for a loose armbar. Westcott couldn't mount a comeback and Pawlak won the decision.

Jimi Manuwa (15-1 MMA, 4-1 UFC) def. Jan Blachowicz (18-4 MMA, 1-1 UFC) by unanimous decision (30-27, 30-27, 29-28) - Light Heavyweights

The co-main event was a bit tentative between the two combatants, with neither man committing to a sustained offensive attack. Blachowicz looked for quick combinations, body kicks, and stifle Manuwa's game with takedowns, but Manuwa did well to stay on his feet. The fight was generally kept in the clinch and the pattern continued into the 2nd round. And the 3rd round. Manuwa was able to push forward and was the aggressor most of the way, but Blachowicz found success with uppercuts and kicks. Jimi ultimately poured on the offense (generally speaking) in the last round and hurt Blachowicz with multiple punches and knees towards the end of the fight. Improved takedown defense shown from Manuwa and more effective offense won him a rather disappointing contest.
