Jay, 32, hit .296/.374/.375 in 433 plate appearances with the Cubs last season, which is adequate. He’s heralded more for his defense and his ability to play all three outfield spots.
The Mariners are losing center fielder Jarrod Dyson to free agency and likely don’t want to rely on Guillermo Heredia next season, hence the interest in Jay. The free agent class for center fielders is otherwise relatively weak.
