We've added a link on the Depth Charts for Visual Year-to-Date stats, which goes to:

This has the same mouseover capability as the Depth Charts, so that if you mouse over WARP for Baltimore catchers, you see the breakout for Wieters, Paulino, and Exposito, for example.  Note that there are 4 stats available: WARP, TAv, FRAA, BRR

It bears noting that the VORP portion of WARP isn't really computed by position, rather if a player has 80% of his PA at catcher, it takes 80% of his season-long VORP and then – for WARP – adds his FRAA at the position (divided by runs per win, of course).
Here's the National League WARP listing:

Really cool, thanks!
Hey, I love this. Biggest surprise (for me) is Red Sox 2nd base.
A few comments/requests:
1. Are you going to do something similar for pitchers?
2. Can you add a sum on the right, adding up each teams' accumulated WARP?
3. Can you remind us how many wins a baseline replacement team would be expected to put up? Such as note somewhere on the page that a "replacement level team" at this point in the season would be expected to have X wins?
4. Does the math involving #1, #2 and #3 above generally line up with reality? I understand teams often outperform/underperform their numbers, but generally speaking if you add up a team's individual WARP is it close to ten extra WARP being equal to ten extra wins? (I am familiar with WARP and the rule of thumb that 10 runs equals one win but know stats are more complicated than that.)

But those are not complaints. This is a great visual tool, between this and the Prospect Tracker you guys are on a roll this year. Incredibly interesting and helpful tools, thank you.
Awesome-what do the colors mean? I see some 0.0's that are green and some are red.
For the colors, I took the range of values from highest team to lowest team, and color-coded the value based on the team's position in that range. Most often, a league-average value should come out as a light yellow or light green (slightly negative or slightly positive), but I see that for NL pinch-hitters, it's coming out red, presumably since Phillies pinch-hitters set the 'curve' so high.
Absolutely outstanding. One of the very best items ever to appear on the site.

I sincerely hope this becomes a permanent feature, both in the team-by-team format and perhaps even a 1-30 listing by defensive position. There may be other useful variations, too.
