The Rays and Mariners have become fairly well acquainted for two clubs based more than 3,000 miles apart. Since Jerry Dipoto became Seattle’s general manager in September 2015, the two sides have traded with each other eight times, including Thursday’s five-player deal that sent outfielder Mallex Smith and Minor League outfielder Jake Fraley to the Pacific Northwest and catcher Mike Zunino, outfielder Guillermo Heredia and Minor League left-hander Michael Plassmeyer to the Sunshine State.
