Looking at the stolen bases tonight: Trea Turner is really fast and he's an excellent base runner. 32/37 on the year, despite missing a couple weeks on the DL. That's with a .314 OBP. This is his third game with 3+ steals in the last three weeks. He's going to do that and there's not much you can do about it. After looking at each of the steals, there were 4 that Miggy didn't even make a throw. 3 were with Turner running. No catcher was throwing him out on any of them. The fourth was with Michael Taylor running, who is also very fast. That pitch was low and outside, almost in the dirt. There was also a runner on third. And Miggy didn't stand a chance of getting Taylor either. One throw was the one to third, that he threw in the outfield. Bad. The two throws to second, with me stopwatching by hand, I have Miggy's pop times between 2.0-2.1. Below average. I saw an article that Statcast had the average pop time at 2.01 seconds last year. So he's not good there. Statcast also had the average exchange time for catchers at 0.73 seconds. I have Miggy below that on both of them. His arm strength is obviously terrible. But he's able to be not-so-terrible by getting rid of the ball pretty quickly. Meanwhile, Arrieta's release time is over 1.5 seconds on every pitch. I have him up around 1.7 on some pitches. The league average is like 1.4. Some guys are below 1.2. Looking at some of Jon Lester's work, he is usually always below 1.4, near 1.3. We're looking at .3 seconds difference or so between the two. Arrieta also is right-handed, has a shitty pickoff move, and does a poor job of holding runners and mixing up his timing to throw them off. Turner was taking off nearly instantly after he started lifting his leg. Arrieta is just really, really bad at limiting base runners. A lot of our pitchers are bad at it. What Willson has done with his arm is amazing. Looking at some of his caught stealings, he's getting pop times below 1.8. That is superb. He's also very accurate with most of his throws, which is also a key. Miggy's not. The throws bounced in and thrown into the outfield are definitely a problem. But if it weren't for Willson being a freaking beast, then this would be happening to us all the time.
