These two just missed each other. Yuh's star was fading around the time Carbajal rose to fame. Yuh only fought out of Korea twice and is 1-1 vs the arguably the best he fought. He wasn't a puncher. I remain a bit skeptical on the extreme lower weight fighters who fight in their home country almost all of the time, have many easy marks on their records and never prove it vs. the best North America or Europe has to offer outside their nation. The judging can be bad in Asia, the foreign fighter often gets the shaft. I did notice Yuh has quite a few split decisions over latino fighters meeting him in Korea, which makes me wonder. Carbajal was a puncher, with fine skills. I don't think Yuh could handle him, but admittedly I only can recall seeing Yuh once. He was technical type.
Yuh gives Carbajal hell just like Baby Jake did, however I don't think he would win against prime Carbajal.
