Though bout actually started well for the challenger who boxed to his strengths early on and used his movement as well as his jab to keep Uchiyama away from landing his power shots. Although Uchiyama did manage to score an occasional eye catching blow they were few and far between as he applied constant pressure but used a conservative punch out put.
Parra boxed well through rounds 2 and 3 and even seemed to take the punches of Uchiyama well, though it did seem like Uchiyama was boxing well within himself and not taking any major chances as he tried to figure out what Parra had.
After having landed several clear head shots, including a love cross part way in to round 3 Uchiyama may have started to feel that he might have a long night in front of him (something he's certainly not used to). That changed drastically in round 4 as an Uchiyama body shot appeared to really rattle the challenger who as forced to take several follow up shots before the bell saved him. The attack, late in round 4 seemed to show a key weakness for Parra and it was jumped on very early in round 5.
Having been hurt the previous round Parra tried to use his legs to maintain a safe distance between himself and the champion. Unfortunately for Parra his legs were all but taken away as an Uchiyama body shot strayed low. The referee admonished Uchiyama for his transgression but it didn't take long for the Japanese fighter to take advantage of his wounded opponent. Just seconds after being told to continue Parra was cracked to the body and sent straight to the canvas where he ended up writing in agony until the 10 count was complete.
A rematch between Takashi Uchiyama and Takashi Miura looks like later this year, a bout many should be excited about as the WBA and WBC titles will be unified.
