In response to Hfxsoxnut's comment:
Full disclosure up front: I do not want Justin Upton to have a great season. I have nothing against him personally. But as anyone who follows this forum regularly knows, he is one of the players that certain posters have wanted the Red Sox to pursue for the last year or two. And from the looks of it, the Red Sox probably could have acquired him. I have had some doubts about him but I also recognize his potential to be a big bat.
Upton got off to a smoking hot start with the Braves and I thought, here we go, he's going to be the MVP, we're going to regret not trading for him and we're going to hear about from the people who wanted him.
In April Upton's line was 298/402/734 (1.136 OPS) with 12 HR and 19 RBI.
But in May his line was 211/327/326 (.654 OPS) with 2 HR and 10 RBI.
In his last 12 games his line is 143/208/163 (.371 OPS) with 0 HR and 1 RBI, and 21 strikeouts.
I also find it a little concerning that with 14 HR he only has 29 RBI. With the bases empty he's hitting 289/390/620. With men on base he's hitting 181/307/347.
He certainly might turn it around of course.
Juston has always had a history of being been a streaky hitter. He also has much less success against RHP and an average glove but his OBP and OPS usually make up for it.
