Oh absolutely. I'll admit I hadn't been 100% convinced by JJ (that is, whether this is an early flash before the league gets a book on him, or is this actually a thing), but has shown some legit mental toughness this week. I mean he makes the error, but then looks completely unflappable and just goes down a gets that pitch in his next AB. Like Big Ben says: "No scar tissue", lol A very good sign.
Now of course, he's gonna eventually cool off and have to struggle a bit like they all do, but...if he gets through that and still hits like this? We've truly got something!
