He just turned 22. He adjusted to AA and then blew away both AA and AAA. He's hitting .500 with an .800 slugging pct in his major league start. I think he deserves a couple of months to adjust to big curveballs.
The Astros announcers said that strikeouts are his bugaboo. They couldn't be more wrong.
JF's special ability is to make contact -- for a power hitter. In the last two seasons, his strikeout percentage has been quite low for a power guy. He doesn't walk much, which is a deficiency, but he compensates by making contact frequently for a power hitter.
I think JF is going to be an all star player in the major leagues. I hope the Reds stick with him. He has fairly unusual abilities -- but as we saw in that last at bat, a two strike hit to knock in a run, he has the knack of hitting the baseball with authority, he does it often, and that's a great thing for a young player.
