On Friday we'll see Japanese icon Hozumi Hasegawa (35-5, 15) [長谷川 穂積] attempt to become a 3-weight world champion as he takes on big punching WBC Super Bantamweight champion Hugo Ruiz (36-3, 32).
Today the two men took part in their medical examinations for the bout which gave us some interesting readings.
Firstly, though not surprisingly, Ruiz is the naturally bigger man. He's 7.5cm (3") taller, and boasts the same advantage in reach. Whether he makes the most of that reach is yet to be seen here, but it does give him a clear edge in physical size.
Whilst Ruiz is naturally much bigger he does lack in experience. Hasegawa has only got a 1-fight edge in terms of experience, with 40 fights to Ruiz's 39, however Hasegawa has fought 277 rounds compared with Ruiz's 145. Likewise Hasegawa has an edge in world title bouts with this being his 16th to Ruiz's 3rd, however Ruiz has fought in 6 "interim" title bouts as well as his 2 world title bouts.
Interestingly Ruiz' fitness impressed at the physical with the champion having a resting pulse rate of just 36 beats a minute, significantly lower than Hasegawa's 55 beats a minute.
Both fighters looked relaxed and confident and Hasegawa has stated that he's less stressed this time around than he was against Martinez, where the IBF same day weigh in give him additional stress.
We're expecting to see Ruiz retain but Hasegawa certainly hasn't shown any signs of fearing his big punching foe here.
