The problem with Devers' OPS -- and maybe the stat's importance when looking at a batter like Raffy -- is the O, which stands for On Base, which is affected by bases on balls. It's very hard for a hitter to walk, especially in late innings with runners on base, when he swings at every pitch -- even when the opposition refuses to throw strikes.
Through the first two months, basically one-third of a season, Devers has 10 walks. That's a lot less than the two worst hitters (by batting average) in the starting line-up: Kike 17, Casas 25. It's even less than part-timer Rob Refsnyder, who has 15 in over a hundred less plate appearances.
Raffy's On Base Percentage of .283 is ghastly, but it's not even as bad as known hackers like Javy Baez or Teoscar Hernandez, or so-far-overmatched youngsters Bobby Witt or Anthony He's-Not-Jeter-No-Matter-How-Much-MLB.com-Wants-Him-To-Be Volpe.
But we all want Devers to hit -- not walk -- as long as he doesn't hurt himself swinging as hard as he can at dirtballs or fastballs over his head... because there's no one else in the Red Sox organization that can follow him in the order and do similar damage to a baseball right now.
