Tatsunori Hara worked with Hayato Sakamoto at Giants Stadium behind closed doors for about an hour on Wednesday (10/6). And while it isn't certain what the two worked on, it is assumed that Hara was giving Sakamoto pointers on hitting. A number of reports also mention Hara tossing BP to Sakamoto at a distance of about 10 meters.
Sakamoto has been struggling at the plate as of late and has just 1 hit in his last 21 trips to the plate (5 games). He has also been hitting a lot of fly balls / pop-ups: 15 fly ball outs over his last 21 trips to the plate.
