Platoon splits are real, and they matter. The trouble comes in when people put too much emphasis on individual platoon performance over a short period of time. It is understandable, of course, and as fans, we have a right to overreact to things. But when it comes to getting to the truth of things, it gets a bit more complicated. One can read about the general principles of thinking about observed platoon performance versus true talent elsewhere. What can be instructive is looking at some concrete cases of unusual or standout performances of certain players. For today, let’s take a look at the platoon histories of a couple of left-handed hitters: Alex Gordon and Robinson Cano.

It was just a little while ago that Kansas City Royals general manager Dayton Moore stubbornly refused to throw in the towel and concede defeat. To the media, at least. Though Moore acknowledged his team was below .500 this season, he said he thought they still had a run in them — that the team hadn’t yet settled into a groove. The Royals, he said, weren’t going to be sellers. If anything, Kansas City was going to be buyer. Based on Moore’s words, the Royals were going to keep going for it, and we criticized that here. And lots of people criticized it in lots of places.

There might be a lesson here, about judging general managers by their words instead of by their actions. Sometimes, you have to say one thing while you try to do another, to keep up appearances. And while the Royals have played fine baseball since Moore delivered his message to the press, there are reports  Moore’s position isn’t exactly what he suggested. From Wednesday: Read the rest of this entry »

It was last offseason that the Royals picked up James Shields from the Rays in a controversial blockbuster. The Royals wanted to improve their pitching staff and take big steps toward the playoffs. The Rays were looking to reload with young cost controlled talent, as always, and they saw an offer they couldn’t pass up. Sure enough, the Royals are on pace to be improved by a few games. The Rays, too, are on pace for the same, as they haven’t missed Shields that much. FanGraphs was opposed to the Royals’ side of things, arguing they weren’t good enough to go for broke, and that in order to get better they also subtracted. The Royals, today, are 43-49. This is going to work as our background and setting.

With the trade deadline approaching, teams are having to self-identify as buyers or sellers. At either end, it’s all pretty apparent, but it gets more blurry in the middle, especially what with the still-new extra wild-card slot. Some teams might neither buy nor sell. Some teams might attempt both. You look at the Royals and you’d think they should shed, but talk to Dayton Moore and he’ll tell you you’re wrong. Moore hasn’t thrown in the towel on 2013, and he seems to suggest he’s most interested in adding, adding pieces of immediate value. So, buying. Dayton Moore seems to identify the Royals as a potential buyer.

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*?

The Royals allowed four runs Tuesday night. Fairly ordinary total, four runs. Not too few to score; not too many to allow. There were 16 games on Tuesday. In 13 of them, at least one team scored at least four runs. In two of them, both teams scored at least four runs. Four might be the least remarkable run total. But then, there’s a thing about these Royals. That was only the second time all month the Royals allowed more than three runs in a game. The other time, they allowed five. It’s been a good month for the Royals’ pitching staff, and so it’s been a good month for the Royals.

It was an impressive streak they put together. Between June 1 and June 14, the Royals played 13 games, never allowing four or more runs. In 2010, the Giants had such a streak of 18 games, but previous to that, you have to go back to the 2002 Diamondbacks to find a streak of at least equal length. Then you have to go back to the 1993 Braves. A few weeks ago, people wondered whether Ned Yost was on the hot seat. Now the Royals have pulled themselves back into the race, and they own the American League’s fourth-best run differential. Thanks in large part to their run prevention, the Royals presently have the look of a contender.

With two outs in the top of the sixth inning in a tied game and runner on second, a manager elects to intentionally walk a right-handed batter with his right-handed starter in order to have that same starter face another right-handed batter. Two singles follow, putting the manager’s team down by two, leading the team to defeat. An intentional walk leading to bad things for the pitching team is hardly a novelty or surprise, but the characters involved make it a bit more interesting.

This happened yesterday. The manager was the Rays’ Joe Maddon, and the batter was the Royals’ Jeff Francoeur. Jeff Francoeur’s game (and lack thereof) has been dissected and discussed to the point of pointlessness. I have made plenty of contributions to the field, so there is no need to belabor that point. Joe Maddon has a pretty good reputation as a manager, but analyzing any manager’s abilities as a whole is difficult for a variety of reasons. This particular sequence struck me as odd, particularly given the Rays’ reputation for trying to gain every little advantage they can.

Is there an ideal ground ball rate for hitters? Should they be thinking about how many grounders they hit? Armed with some spreadsheets and a couple conversations with some Royals’ hitters, let’s see what we can discover.

If you knew Emilio Bonifacio’s younger brother was an outfield prospect in the Kansas City Royals’ farm system, you might assume the two are roughly similar. But Emilio — a speedy, switch-hitting, utility man for the Toronto Blue Jays — and Jorge have little in common, at least when it comes to their games. Jorge, the younger of the pair, is a burly right fielder with a strong arm. He was enjoying an excellent campaign as a 19-year-old in the Carolina League when he broke his hamate bone Tuesday during batting practice. Reports suggest he’ll miss six to eight weeks.

It’s difficult to say how the injury will affect his development. Even after returning to the field, the alleged power-sapping effects of a hamate break can linger. Whether appropriate or not, the injury will cast a shadow over the rest of his season.
