Kravchenko did like tennis - though who doesn't? (Even Petro Poroshenko plays sometimes, when he's not too busy.)
Here's part of the Feb. 27 Ukrainska Pravda piece, which mentions that last Kravchenko sighting, at the Crimea Regions Party branch conference in Simferopol:
[Kravchenko] refused to discuss with the local journalists the civilian appointments to the new government's "power" ministries' posts. He did point out that that he was currently more interested in tennis and football, because he was on vacation.
It remained unclear what exactly he was doing at the meeting of the Regions Party.
