Emerson has stayed healthy all of 2025 and has made major strides in his game. He's scored 58 runs in 90 games with the High-A Everett AquaSox as of Sunday. He's hit 16 doubles, five triples and 11 home runs with 51 RBIs. He's slashed .281/.388/.453 with an .841 OPS. His triples, home runs and RBIs are all career-highs.
