Obviously, we've had a decent amount of talk on here about the down year in the farm system (and I generally agree that it's been pretty mediocre). That said, I was looking over Robbie Grossman and Starling Marte's stats this morning, particularly month by month, and its pretty damn rewarding. I knew they were both having good years, but lately those good years are starting to turn ridiculous. Both have had essentially one outlier month at the plate (Grossman had a .670 ops in may, and Marte had a .719 ops in July), and outside those some pretty crazy numbers.
Marte's OPS by month: .816, .829, .899, 1.097
Marte's SLG by month: .453, .475, .522, .659
Grossman's OPS by month: .826, .995, .917, 1.068
Grossman's SLG by month: .400, .495, .467, .648
Of course, looking at a season as a whole you shouldn't remove a bad month. Bad month's happen. Its baseball. Regardless, I still think both players are not only starting to show off the talent that got them recognized, but also some very serious improvement during the year in their skill sets. I dont think either player's power is a fluke, and if they can each hit 15-20 home runs a year (which looks distinctly possible) we could have a ridiculously talented outfield in the near future, as well as a massive, wonderful headache regarding which outfielders to keep and which to trade. Should be fun to watch what they do in AA and AAA. Here's hoping they keep it up.
