Brewers' pitchers' numbers, last 30 days

As I had a second, I wanted to see if this meltdown over the last month could be attributed to some/most/all of the pitching...I decided to look at by IP, simply because those that pitch the most (or at least get the most outs) will have a greater influence...here's what I found:

1. C Capuano 35.1 IP, 8.21 K/9, 1.51 WHIP, 5.35 ERA...definitely not a good #2 starter
2. Y Gallardo 31.2 IP, 7.21 K/9, 1.31 WHIP, 4.83 ERA...skewed after yesterday's poor outing
3. C Vargas 28.2 IP, 5.74 K/9, 1.56 WHIP, 6.28 ERA...has definitely dropped off
4. J Suppan 28.0 IP, 3.86 K/9, 1.61 WHIP, 4.18 ERA...last three numbers surprised me...he puts a lot on, but keeps them from scoring
5. D Bush 23.1 IP, 7.40 K/9, 1.52 WHIP, 5.79 ERA...just slightly better than Vargas
6. M Parra 17.2 IP, 9.42 K/9, 1.22 WHIP, 3.06 ERA...2 of 6 appearances have been 6+ innings, with only 1 ER in each
7. C Villanueva 14.1 IP, 10.21 K/9, 2.13 WHIP, 11.30 ERA...needs a rest
8. B Shouse 13.1 IP, 7.56 K/9, 0.84 WHIP, 2.03 ERA...plus he hasn't given up a HR all year
9. D Turnbow 12.1 IP, 12.64 K/9, 1.65 WHIP, 5.11 ERA...either fans 'em or gives up a hit
10. F Cordero 12.0 IP, 9.00 K/9, 1.42 WHIP, 4.50 ERA...fans 1 per inning...but lets 1½ on
11. C Spurling 10.1 IP, 6.24 K/9, 1.58 WHIP, 7.84 ERA...but only allowed earned runs in 3 of last 10 appearances
12. M Wise 8.0 IP, 7.88 K/9, 2.63 WHIP, 6.75 ERA...now only useful to get a lefty hitter out
13. S Linebrink 5.0 IP, 10.80 K/9, 1.20 WHIP, 1.80 ERA...small sample, but needs to be THE go-to reliever after the starter comes out

Conclusions:

1. Parra should replace Vargas in the rotation. Vargas hasn't had it lately, and Parra has earned the chance to start
2. Linebrink should be the first choice out of the pen in any close game, as he keeps them off the bases
3. Spurling can also get an early look, but yank him if 2 of the first 3 hitters gets on
4. Shouse should be used for a whole inning, not just to face one lefty
5. Wise should be used to face one lefty
6. Turnbow should be used in the 7th and 8th innings in tie games
7. Villanueva should get sent down to Nashville, and be replaced by Stephen Bray (5-2, 1.61 ERA, 1.11 WHIP, 8.51 K/9 in Nashville)

Finally, I'd like to see Ned Yost, Mike Maddux and Bill Castro sit down with each player individually, and aprise them of their new role, and then have a meeting of all the pitchers to tell them that they need to try something to shake them up. I'm not certain if any of these would work...but it can't hurt to try.
