| 0:00.0 | A wise man once wrote, deception seems impossible to quantify. How are you going to put a number on something like the invisible thrown by Usmaro Petit? The ball is there and then it isn't, and then it's back. Put that in your number machine, nerd boy. The year was 2016. We've come a long way, haven't we, you know? |
| 0:18.3 | Are those my words? Those are. |
| 0:23.6 | Oh, Lord, we're in trouble today. |
| 0:28.2 | Today on Rates and Barrels, we dig into an attempt to quantify deception with a new model created by our friend and co-host, Trevor May. |
| 0:31.1 | Let's go. |
| 0:44.0 | Thank you. |
| 0:47.6 | On this episode, we look at Trevor's new deception model. |
| 0:50.9 | Talk about a few guys that are popping there, both on the starter and reliever side. |
| 0:55.0 | We're going to dig into the Tampa Bay raise. Enos stumbled into a really interesting question |
| 0:59.9 | about how teams are pitching the raise as a group. We'll try to figure out what's happening behind |
| 1:04.9 | their fast start, 24 and 12 entering play on Thursday. Only a half game back of the Yankees. We're |
| 1:10.8 | also going to dust off a |
| 1:11.7 | how I'd pitch this guy segment for Junior Cam Minero. Eno, I got to ask, since you wrote that piece |
| 1:18.7 | over at Fangraphs in 2016, a lot has changed. Do you feel like you were really onto something 10 years |
| 1:24.5 | ago with quantifying deception. |
| 1:30.3 | Yeah, I mean, it was poorly done. |
| 1:33.0 | I guess I was just sort of ham-fisted math. And I took basically release point and tried to make a model that predicted movement against |
| 1:40.7 | release point. |
| 1:42.3 | And then I looked at people who had the most deviation from it. |
| 1:45.4 | And some of the stuff was not so helpful because it was like Darren O'Day and Brad Ziegler, |
| 1:51.7 | where it's like, oh, they're just, they just have a really weird release point. |
| 1:57.3 | But it is interesting because some of those problems still exist to till today. |
