Some things appear to be off in this article, but I realized the same thing about Deduno. This is a good sign. But it just makes this Correia abomination way worse.

Something is fudged up. Brock's working on getting some solutions as to why the GIFs are not appearing. Check back tomorrow to see it in full glory.

I am a big fan of Deduno and hope that he has found a way to decrease his walk rate. If that happens, he can be awesome. I am setting my DVR for Thursday's game!

People need to look a pitchers like Deduno a little more closely and understand that the high walk rate which is such a flashing number in his pitching stats is not as negative an indicator as people would have you think given Deduno's low hit rate.
Compare two pitchers with similar WHIPs and the pitcher with the higher walk rate will fare better because a walk only puts the batter on first base and only advances base runners in a force situations a single base while hits will result in more total bases for both batters and runners.
Liam Hendriks (1.547) and Sam Deduno (1.544) had nearly identical WHIPs for the Twins last year but Hendriks' was based on 11.2 H/9 and 2.7 BB/9 while Sam's was from 7.9 H/9 and a 6.0 BB/9. Hendriks surrendered 184 total bases to batters versus only 112 for Deduno. This means that for the same number of batters put on base, Deduno gave up 65% fewer total bases. (And this doesn't even account for the extra bases by base runners.) In a similar number of innings pitched (85 for Hendriks, 79 for Deduno) Deduno gave up 21 fewer runs.
I won't throw Liam's 1-8 mark in the argument because his run support was horrible (3.4 runs per game.) while Deduno's was decent at 5.1. (and, by the way, Diamond got 6.0. Care to guess what kind of pitcher Diamond will be in 2013 with, say, a run and a half fewer per game?)

If he lowers his walk rate to around 4 per 9 then he could be this generations Dave Stewart. He didn't have much success until his late 20's then out of know where won 20 games a year 4 years in a row. While I won't expect 20 wins a year, Dedunno could put together 3-7 years of 12-15 wins as a starter. I think a pitcher like him makes the rest of the rotation better because of the way he pitches is a different look then the other starters.

Looking at the raw data from last year is only partly helpful. I'd like to see the trend line. When he came up, he was walking five, six guys a game and pitching five, six innings a start.
He did that for about a month and Anderson got him to make some adjustments. Most notably, he had the catcher sit down the middle and Deduno would throw it at the mit and the ball would move over the corner for a strike. Prior to that, he would try to hit the corner and it would move off the plate. Consequently, he was only throwing his fastball for strikes once every fourth or fifth time. Hence all the 3-0 counts. But late in the year, he was throwing strikes with his fastball and guys started swinging early in the count. When they did, they hit weak grounders. When they didn't he finished them off with the slider.
Slowly, the walk rate lowered. By the end of the year, he was walking something like 3/9. Meanwhile, his BA against was under .200. He carried that over into winter ball and dominated. Now he's keeping it going in the WBC. The big test will be tomorrow, when he starts against a USA line-up that could beat most all-star teams. Because he's been away from camp, we've kind of forgotten about him. But with Hendriks and Gibson struggling, he could make this team with a strong showing tomorrow.

In his first 46 innings, he walked 36 batters in 46 innings -- a 5.8 BB/9 ratio. In his last 33 innings - presumably after these changes from Anderson - we walked 17, an improved 4.6 BB/9, right? HOWEVER, if you look at the overall pool of batters faced, Deduno actually walked more hitters in the latter sample (8.5% in last 33 innings versus 5.6% over first 46)

Let's talk about "regression"
One thing I've noticed about Deduno, and the reason I find him fascinating, is that he appears to have developed a style that fits his abilities. He's an excellent fielder, quick as a good shortstop. His whippy arm motion is unusual for an overhand delivery, but it appears not to damage his shoulder or elbow. Ever notice that his throws to first and second base are straight as an arrow and pinpoint accurate? Deduno knows very well how to throw a ball straight.
Whether his new, more whirly deliver results in better accuracy is yet to be seen, but it's not impossible. The fact that he falls off so far to his left indicates that he is accelerating in that direction from the start. Does that delivery really look more repeatable to you than his supposedly more disciplined finish from last year? Throwing a baseball combines straight line and rotational movements. When you find a good recipe of such whippy movements, you can wind up with a Roger Federer forehand, or a Sam Deduno fastball for a strike.

It would sure help if he could be a marginally decent starter for this team....Win Twins.

Either way, we are dealing with small samples, and it's really hard to project such an unpredictable player with such small samples. All I know is, since the adjustment, and including his winter ball and WBC innings, his walk rate is in the area where he can be successful with such a low BA against. Relative to the current competition (Cole DeVries, who walks hardly anyone but gives up a lot of hits) his WHIP should be lower, giving him a better chance at success.

If he K's 5 guys in a nine inning game, that's a 5 K/9 ratio.
But let's say he pitched two nine inning games and struck out 5 guys in both.
But in one game, he walked 8 batters, gave up 10 hits, and hit 3 batters. That means he struck out 5 of a possible 48 batters (27 outs, 8 walks, 10 hits, 3 HBP).
In the other game, he walked 4 batters, gave up 5 hits, and hit no one. That means he struck out 5 of a possible 36 batters (27 outs, 4 walks, 5 hits).

Here's a more detailed explanation as to why to stop using K/9 & BB/9:
What happens when we use the 'per 9' metrics is that we lose accuracy, because our measurements have become subject to the tyrannical forces of BAbip. As a pitcher allows more Hits per Ball in Play, he becomes less efficient. He ends up facing more batters and getting fewer outs, which consequently means fewer innings. But if he's still striking out batters at the same rate (say 20%) all the while, his K/9 is going to look a lot shinier with those fewer Innings.
