The Seattle Mariners have selected the 23-year-old outfielder Taylor Trammell from Triple-A Tacoma in a trade with the Cincinnati Reds for pitcher Austin Nola. He was a compensatory round pick in the 2016 draft. Although he is only 23, Trammell has already begun playing as the Mariners’ everyday center fielder. As of Tuesday, he has hit.432 with seven home runs and 14 RBIs in 350 PAs. His OPS must rise above.700 soon to guarantee his roster spot in the major leagues.
