At the All-Star break and heading into the month of August, I wrote a pair of articles breaking down my position-by-position power rankings. With the calendar turning over to September and the postseason push heating up, now seems like a good time to update those rankings.
I've made updates as to who I feel have been the 10 best players at each position based on their performance in this season. I've taken into account their all-around offensive production, their defensive contributions and then what they have meant to the success of their respective teams so far this season.
Also included in my statistics is each player's FanGraphs WAR. While WAR is a useful stat in gauging a player's value, it's not the be-all, end-all stat that some view it to be. As such, don't expect this to simply be a list of the top 10 in WAR at each position.
This time around, rather than separating relievers by "middle reliever" and "closer," I have broken them up by right-handed reliever and left-handed reliever. In the past, it was hard to peg where guys like Koji Uehara, Mark Melancon and Joaquin Benoit fit into these lists, so this allowed them to be included.
With that out of the way, let's take a position-by-position look at the updated player power rankings entering the final month of the season.
Note: There is no slide for DH, but it bears mentioning that David Ortiz (.951 OPS, 24 HR, 82 RBI) is the best DH in baseball by a decent margin. Billy Butler (.804 OPS, 14 HR, 69 RBI), Victor Martinez (.771 OPS, 11 HR, 73 RBI) and Kendrys Morales (.778 OPS, 17 HR, 69 RBI) also deserve mention, but after those four, there's not much to speak of.
