Otake, who returns to the ring later this month against Satantung Sor Bangkhru (0-1), will have used the spar to round off his training, in fact if his blog is right this likely to be his last sparring session before his bout on March 16th.
As for Amagasa he'll be back in the ring on April 16th, in fact exactly one month after Otake's bout, and will be in the UK against the unbeaten Josh Warrington (22-0, 4).
For Amagasa the spar will have been more than just tapering off his training. In fact it will have been partly about getting used to a high action fighter, which Otake is despite his limitations, and also getting hints on British conditions, something that Otake faced in 2014 when he battled Scott Quigg. Those little hints could well be the difference between winning and losing for Amagasa who knows that a win could move him towards a world title fight later in the year.
