From what I can see from the stats, he's hitting the ball on the ground more and his BABIP is pretty high, though not so high it accounts for everything (.356).
He's hitting about 100 points better on the road (which is good news for a Reading prospect) , and June/July have been amazing, posting an OPS of nearly .900 since May 31. He's almost exactly balanced vs. L/R. he's killing it late and close (1.100 OPS) and hitting very well behind in the count.
Could be the "Terry Jones" effect where any batter can get hot for 200 ABs....but maybe he's hitting it harder--they don't have minor league Line Drive stats I can find anymore...OK, found them .. his LD% is 20% overall this year which is above average but not out of the world. I don't have his LD% from previous years.
The only numbers that stand out for him are his GB% which leads the team by a decent margin, and his contact percentage, which is also very high. BB% only around 7, could be a bit higher...
