Of the two men it's the talented and heavy handed Mexican who is expected to shine. He has long been considered one of the top Mexican fighters and, before turning professional in 2012, he had been a genuine amateur standout. In the unpaid ranks Valdez had twice competed at the Olgmpics, had won gold at the 2008 AIBA Youth World Championships, Silver at the Pan Am games in 2009, 2010 and 2011 and a Bronze at the 2009 World Amateur Championships.
So impressive was Valdez's amateur career that when he turned professional, soon after the 2012 London Olympics, people were already talking about him like a nailed on world champion. Like so many top prospects in the West however his journey to the top wasn't particularly rushed. Instead it was a slow build as he gradually stepped up his competition, beating Jose Ramirez in his 15th bout, Christ Avalos in his 17th and Evgeny Gradovch in his 19th. Finally his world title shot came in his 20th bout, in which he stopped Matias Carlos Adrian Rueda for the then vacant title.
Valdez's rise to the title had been pretty straight forward, and that was the case in his first defense, a one sided beat down of Japan's Osawa, who was tough but out classed and eventually stopped in round 7. It wasn't until his most recent defense, a 12 round war with Miguel Marriaga, that chinks were first seen in Valdez. The Mexican showed great toughness and will to win, but was hurt several times, looked defensively open and struggled to connect with his frightening power. He still won, but for the first time he was made to look human.
In the ring Valdez is a fast handed, technically well schooled boxer puncher. Defensively there is flaws, and questions do continue to be asked about his stamina and whether or not he can be versatile enough to over-come fighters who can take his power. Whilst he did defeat Marriaga, that bout left more questions than answers.
Whilst every fight fan has likely heard of, or seen, Valdez it's fair to say far, far, fewer have seen Servania. In fact many of those who have seen the Filipino would probably have only seen one fight of his, his contest with Konosuke Tomiyama which took place in 2013 in Macau as part of Top Rank's Macau experiment. That bout was a thriller, with Servania being dropped twice in the opening round, and dropping Tomiyama twice before claiming a 9th round split technical decision. Despite the drama in that fight Servania is actually a fighter who typically fights safely and doesn't engage in wars.
In the ring Servania is a technically solid fighter, who has slowly but surely racked up notable wins, which have often gone under-the-radar. Those wins have included victories over the likes of Genaro Garcia, Angky Angkotta, the aforementioned Tomiyama, Rafael Concepcion, Alexander Munoz and Jose Cabrera. Those wins won't resonate with too many fans, but they are decent wins over decent names, even though they were mostly on the slide. They have shown that Servania is a solid boxer-mover, he hits harder than his record suggests and he has rarely lost a round during his 29 bout career. It's also worth noting that despite being a bit of a veteran he is only 26 years old, with almost 9 years of experience under his belt.
Although experienced and talented this is a huge step up for Servania, and he would need to score one of the biggest upsets of 2017 to over-come Valdez. We know Servania is talented, but we can't see him having the tools needed to really test the champion. Servania should be able to have some moments, but we suspect he'll end up being stopped in the middle rounds by the more powerful Valdez.
