It’s bullpen upgrade day. A few hours after the Tigers added Jose Veras, the Braves got the lefty reliever they’ve been hunting for, landing Scott Downs from the Angels, and they got him for what amounts to a hill of beans.

Working against Downs’ value was his age (37), his contract (remainder of $5M salary), and his splits (basically a LOOGY at this point). Adding a couple of million in payroll for a guy who is probably a situational reliever at this point in his career seems to have been enough to scare off most bidders, because the Braves only had to give up reliever Cory Rasmus to get him.

The last time I wrote about Edge% it was in the context of the Tampa Bay Rays using it to get their pitchers into more favorable counts on 1-1. But now I want to take that topic and drill a little deeper to understand how often edge pitches are taken for called strikes.

Overall, pitches taken on the edge are called strikes 69% of the time. But that aggregate measure hides some pretty substantial differences. Going further on that idea, I wanted to see how the count impacts the likelihood of a pitch on the edge being called a strike.

Here are the results:

I know a lot of you loved this guy, so this thread is a place for you all to say goodbye…

Jeff Francoeur always seemed destined to be a Kansas City Royal. Even when he was a Georgia-born-and-raised Atlanta prospect, he was always destined to be a Royal. Sort of. It seems as if very early on Dayton Moore’s tenure as General Manager of the Royals, Joe Posnanski was predicting that Moore, who played a big part in Francoeur’s drafting and development when Moore worked for Atlanta, would find a way to acquire The Natural.

In his Major League debut for the Mets, 23-year-old Zack Wheeler struck out seven hitters in his six innings of work. Of those seven strikeouts, six came on fastballs — and of those six, four came on whiffs induced by fastballs.

This got me wondering, what pitchers this year have generated the largest percentage of their strikeouts off of their fastball? And how many generated those strike outs on swings and misses on fastballs*?

Last year I reintroduced VOL, a custom metric that attempts to measure the relative volatility of a hitter’s day to day performance. It is far from a perfect metric, but at the moment it’s what we have.

We are a little more than two months into the season, and that means it’s time to check on early season velocity trends. As I’ve mentioned before, declines in velocity are a less reliable signal in April and May than in June and July, but nevertheless large declines can still be a solid predictor that a pitcher’s velocity has in fact truly declined and will remain lower at season’s end. Almost 40% of pitchers that experience a decline in April — and almost 50% in May — will finish the season down at least 1 mph. And while the signal gets much stronger in July, 40% is still a pretty sizable number.

So let’s take a quick look at the major decliners from April and May.

The Astros have the worst team strikeout rate in the history of baseball. It’s not even particularly close, as these things go. The Astros have struck out in 26.8% of their plate appearances. The 2010 Diamondbacks struck out in 24.7% of their plate appearances. That’s a gap of more than two percentage points, in a rate that usually fluctuates between 15-25% or so. That’s terrible, and the only consolation is that the Astros were projected to be terrible so no one really cares.

Then right behind the 2010 Diamondbacks are this year’s Braves, at 24.5%. So, this year’s Braves have the third-worst team strikeout rate in the history of baseball. Between third and fourth there’s a gap of another 1.6 percentage points. The Braves, obviously, have the second-worst team strikeout rate this season. Just glancing at their current box score, they’ve struck out six times in four innings against Ian Kennedy on Wednesday. They’re going to strike out more before this game is through. Probably. I guess I can’t be certain.

Andrelton Simmons is solid with the glove. He makes all the plays he should. Andrelton Simmons is spectacular. You should see his arm. Really, though, Andrelton Simmons is spectacularly solid.

Ninety-nine — a number rarely seen once, let alone multiple times from the same pitcher. In his last start, Mauricio Cabrera touched 99 mph enough for teammates charting in the stands to chuckle and shake their heads in disbelief.

Win probability said the Reds had a 4.3 percent chance of winning when Devin Mesoraco stepped to the plate against Craig Kimbrel. There were two outs and nobody on base. Win probability obviously didn’t know Craig Kimbrel was pitching.

According to Tom Tango’s run frequency calculator, given Kimbrel’s career .154/.240/.208 line against, a run is expected to score off Kimbrel 2.3 percent of the time with two outs and the bases empty. Actual win probablity, then, is more like 1.0 percent, considering Atlanta would be expected to win half the times Kimbrel gets out of the inning with a tie.

Naturally, then, Mesoraco and Shin-Soo Choo hit back-to-back home runs, and the Reds left with likely the most improbable walk-off win of the season.
