Tino Martinez Praises Yankees For Edwin Encarnacion Trade, 'He's The Best!'

The Edwin Encarnacion trade was a STEAL for the Yankees ... so says NY legend Tino Martinez, who tells TMZ Sports, "It's a great move!"

"He's a home run hitter," Tino says ... "He's the best!"

Encarnacion was just traded from the Mariners to the Yankees in a move that only cost the Bronx Bombers a low-level prospect and some cash.

And, Tino -- who was also famously dealt from the Mariners to the Yankees before NY's 1996 World Series-winning season -- is fired up for the move.

As for Clint Frazier -- the stud outfielder who was demoted back to the minors in order to make room for Edwin -- Martinez says he's confident the 24-year-old will be just fine.

"Clint Frazier is an awesome player, man," Tino says ... "He'll be back!"
