There is an explanation to a lot of this below the chart for those who may not understand what they're looking at, but are interested. Skip all that if you already know what these stats are.

Observations:
Thank God Robson is back.
Mangum is still the sh*t. He's fallen back some in the past month actually, he's still playing at a very high level.
Kruger has also slipped some, but has still been solid.
Humphreys has stayed about the same, and he and the previously mentioned 3 have been the 4 best hitters on the team over the course of the season given their playing time.
We really need to find a way to get Marrero less playing time.
Luke Alexander is actually one of the few players who've increased their RC average over the past month. His AVG is just so low, it's hard to justify him playing too much at this point.

Color highlighting is just to help with visual to highlight the best and worst in each category since sorting isn't available.
RC (Runs Created) - This is the single best indicator (in my and many others opinion) in determining how valuable a player has been based on what they've done this season. Specifically, this stat estimates the number of runs a hitter contributes to his team. This is a very complex formula, and is probably the #1 stat used in sabermetrics in some form or another. I use the advanced formula for RC in this breakdown.
(RC/PA)*4 - This is Runs Created divided by Plate Appearances times 4. This turns RC into an average so players can be compared equally regardless of how much they've played. It's divided by 4 to give an estimated view of how many runs they create per game. I came up with this, just for comparisons sake.
OPS - On Base % plus Slugging %
BABIP - Batting average on balls in play. This is another sabermetric stat. This stat measures how many of a batter's balls in play go for hits, excluding home runs. It is a good tool for measuring the sustainability of a hitter's performance, as a very high or very low babip is hard to maintain.
TB - Total bases
HBP+BB - Hit by pitch + walks
CS - Caught Stealing
Sac - Sacrifice Hits
GDP - Ground into Double Play
