I think Reyes has potential to be a plus bat. Either he breaks out a bit this year or he just proves to be another Ryan Raburn who couldn't hit before July but looked like an All-Star hitter in August and September, when the team no longer had a shot at winning anything.
If you split Reyes' 2021 season in half, right at the midpoint he hit .327 with OBP of .352 in the second half, No real power numbers, but with his size if he bulked up a little bit he probably could show some power. Switch hitter, competent in all 3 OF spots. I think he's a really good option for a 4th OF guy. He gives Hinch a lot of versatility with his lineup and defense. If you could get .275/.330 with 10-15 HR out of him, that's really good for that role.
