I like Happ quite a bit and think he's a guy who can potentially give Zobristian production(in slightly different proportions) and positional flexibility, but that's a lot to put on him when he didn't really hit in AA and he's got 40 games above that level. We haven't seen how he's going to react to the inevitable adjustments that are coming. I've written before about adjustments he's made, but doing so in the Carolina League isn't quite the same. For an example of how sample sizes deceive, Aledmys Diaz hit about .450/.500/.800 for a month and he's been mediocre trending towards bad ever since. If Happ can play a capable CF then that's a big point in his favor, but that's far from decided at the moment. As far as Eloy goes, he's definitely a corner OF, but there aren't many players regardless of position that have shown his ability to hit for both average and power, especially with age considered. Here's the list of minor leaguers in full season ball who hit .320 with a .200 IsoP that weren't AAAA guys: Mitch Haniger (25 at AAA, .446 wOBA for the Mariners this year) Yermin Sanchez (24 at Low/High A) Eloy (19 at Low A) It's early but you're seeing Eloy become more selective as pitchers get more afraid of him too, he's got 5 walks in 37 PAs in the early going. The only thing that gives me pause about Eloy is the multiple muscle injuries are worrisome, it's an equalizer in the other direction like Happ playing a capable CF. So in my mind, Happ is doing good work and by virtue of being at AAA/MLB already has a non-trivial head start in contributing, but I'm still trading him before Eloy.
