On Tuesday morning, Twins pitching coach Neil Allen made his weekly appearance on a local sports talk radio show. He said a few things that made my ears perk up. I've been busy this week, and just now have had time to go back and double check what I heard, and to do some associated research. First, I'll say that there is no doubt that Neil Allen knows more about pitching than I'll ever know. That disclaimer out of the way though, I can't help but wonder if he is the right man for the job, based on the things he said on Tuesday not really jiving with reality. At the trade deadline, the Twins sent Ricky Nolasco and Alex Meyer to Los Angeles, in exchange for Hector Santiago. Santiago is a guy who has had some success in this league, and was pitching very well at the time of the trade. Feelings were mixed at the time of the trade, but mostly it was lauded as a good trade for Rob Antony. The feeling was that Santiago could be a potential short term fixture at the back end of the rotation. At the time of the trade, Santiago was having a very good run. Over his final 6 starts with LA, he had given up just 7 earned runs, and struck out 34 batters in 35.1 innings. He also had walked 21 batters, but that seems to be part of his recipe for success. From 2012 through 2015, he posted ERA's of 3.33, 3.56, 3.75, and 3.59, despite walking 236 batters through 527.1 innings. Now, we all know that approach doesn't sit with the way the Twins traditionally want their pitchers to pitch. But, if it's working, why fix it, right? Not so fast, at least that's what I took from this statement from Allen on Tuesday: "But in his defense, he's been working on an awful lot of stuff too since he's been here. Because he's said he got out of whack and out of sync and did some things out in Anaheim. And so he's been coming in here and working on some things too, and believe it or not, he's not happy with the way he's throwing the ball too, and we all know that and we all see that. But there's a lot of mechanical flaws that he's been working on that we do see getting better. His base on balls are down," Allen is correct that his walks are down. In fact they are way down, from 11.1% in LA, to 3.3% here. However, his strike outs are also way down, from 20.8% to 13.0%. Whatever changes the Twins have made to Santiago, have cut down his K's nearly in half, and hitters are absolutely tee'ing off on his pitches. Opponents line drive % is up from 13.5% in LA, to an astonishingly 24.3% here, and opposing batters are hitting .364 off him since the trade. From here, Allen starts to talk more specifically about Santiago's pitches. "His location with his fastball, believe it or not, has been better. It's his off speed that has been kinda beating him up and he's been getting the ball up in the zone when he's trying to shut down big innings and it's cost him." Fangraphs pitch data doesn't support this statement though. In LA, his fastball was a positive 0.1 runs above average per 100 pitches, while since coming here its been worth a NEGATIVE 1.89 runs above average per 100. Or, maybe his fastball location has been better, perhaps it's been too much better, as in right down the middle? His fastball velocity is also down significantly since the trade, from 91.8 to 90.4. That could show that he's playing hurt, or it could support my theory. That being that they saw the walk rate throughout his career and told him he can't do that here, that he needs to start pitching to contact. Perhaps he's always been a bit effectively wild in his career, walking plenty, but stranding them by getting plenty of K's and producing weak contact. Perhaps he's found that the only way he can locate the fastball consistently over the plate, is by taking a little off the velocity, which has led to less strikeouts and guys making better contact with it. Aside from Ervin Santana, who probably needs a pitching coach the least of anyone on the team at this point in his career, has any starting pitcher for the Twins pitched up to his potential this season? Berrios, Gibson, Duffey, Hughes, anyone? Now again, I'm far from a pitching coach. So, maybe i'm more on something, than on to something. That is entirely possible. Those who know more than me, feel free to chime in on the things involving more nuance than the numbers alone show, and why I might be wrong (or right).
