Freddy Freeman of the Atlanta Braves started a hot streak on May 16th. Since that date through June 8th he compiled a .342/.375/.500 slash line, good for a .380 wOBA. The relative closeness of his BA and OBP raises a red flag however. His walk rate is way down in this period. Now, that by itself is not a concern. He's collecting a ton of hits, and given the choice between a hit and a walk for getting on base, take the hit. The low walk rate might also indicate Freeman is picking up bad habits.
Pitchers worked Freeman away during this period:
Freddy is getting good results no matter where the ball is pitched:
Not the three hot zones out of the strike zone, one up and away, one down and in and one down and away. He's chasing balls way out of the strike zone:
You can see the bad habit developing. The green areas represent 50% swings, and most of those are way out of the strike zone. Plenty of yellow and orange shows up there as well. With all those swings, he's not giving himself a chance to get in good counts for hitters:
It looks like his success on some outside pitches is causing him to go after more of them. That may work short term, but once pitchers realize they don't need to throw strikes to get Freddy to swing, he'll receive fewer and fewer pitches he can drive.
