Arquimedes Caminero: Granted release to play in Japan

The Mariners granted Caminero his release Friday to allow him to pursue an opportunity in Japan.

Caminero throws gas but hasn't been able to put the ball in the strike zone with consistency in four major league seasons. The right-hander made 57 appearances between Pittsburgh and Seattle in 2016, posting a 50:33 K:BB over 60.2 innings. He turns 30 in June.
