Since taking over as the Mariners’ general manager on Sept. 28, 2015, Jerry Dipoto has made 71 trades. Over the last 32 months, 152 players, ranging from veteran All-Stars to career minor leaguers, have been welcomed to Seattle or said goodbye to it. Dipoto dealt three of those players away only to end up reacquiring them later. By the end of 2015, he’d already made 10 trades involving 31 separate players, and in one afternoon in January 2017, he nabbed outfielder Mallex Smith from Atlanta, then moved him to Tampa in a package for lefty Drew Smyly roughly an hour later.
