Two more Cubans defect:

The guy of interest is the older brother who plays 3B:
"Yulieski, 31, was ranked by Baseball America’s Ben Badler as the No. 1 player remaining in Cuba. The third baseman is a career .333/.414/.577 hitter as a professional and has enjoyed success in both Cuba and, recently, Japan. The elder of the two brothers that defected (the oldest Gurriel brother, Yunieski Gurriel, apparently did not join his younger siblings) was recently allowed to play in Nippon Professional Baseball, where he batted .305/.349/.536 with 11 homers in 62 games for the Yokohama Bay Stars. Thus far in the 2015-16 Cuban season, Yulieski was batting a ludicrous .535/.604/1.012 with 10 homers in 106 plate appearances across 23 games.
Badler has previously praised Yulieski for his plus bat speed and plus raw power to all fields, drawing comparisons to David Wright and Hanley Ramirez from Badler last spring (prior to Ramirez’s poor debut season in Boston). He’s said to be an above-average defender at third base, where he’s best suited, but also capable of handling second base adequately."
Could it be possible the Braves caught wind of this happening, and that's what caused them to move Olivera to LF so quickly? Probably not, but fun to think about at least.
