Braden Bishop falls into a very similar category as Jake Fraley as an outfielder who has not been able to hit in the majors and has also not been able to regularly get in the lineup. Bishop was drafted by the Mariners in the third round of the 2015 draft and currently is the Mariners’ 18th ranked prospect on MLB.com.
The reason he was drafted so high was for his defense as he is one of the best defensive prospects in the game, but his offense has to get better for him to be something in the majors. His MLB.com prospect rating for defense is a high 65 (20-80 scale) but in 86 plate appearances with the Mariners he has hit .128 with a .336 OPS.
His minor league stats are not horrible, as in 5 minor league seasons he has a .761 OPS. He also had an .847 OPS in 211 plate appearances along with some flashes of power with 8 home runs in AAA in 2019. So, if he could hit at a similar level in the majors he could be a starter because of his defense. But, with the Mariners young crowded outfield, it will most likely not be in Seattle.
