I know of at least one person who did not expect Pittsburgh Pirates first baseman Josh Bell to have the monster breakout season he's currently having. In the days leading up to Opening Day 2019, an anonymous scout absolutely shredded Bell in Sports Illustrated's season preview. The scout did not hold back.
Here is the anonymous scout's comment:
Josh Bell can't play. He's not a good defender. He's a big lump. He has bad agility, bad footwork. He can't run. Supposedly he's a big power threat, but he hit 12 home runs at first base. This is not a kid! This is his third year in the big leagues! I don't think he's got the ability to get better.
I can't help but wonder about that scout's job prospects at the moment. Thank goodness for anonymity, huh? Bell, last week's National League Player of the Week, goes into Friday's game with a .339/.408/.718 batting line and 16 home runs, four more than last season in 382 fewer plate appearances. He leads baseball with 47 RBI and is all over the league leaderboards.
