Fun with Arbitrary Endpoints: The Royals in April


Last year, I wrote an article on using arbitrary endpoints in baseball. If you’re unfamiliar with that phrase, it’s basically citing a stat using a date range that is somewhat, well, arbitrary. In the middle of the season, we’ll see that a certain player is slugging .740 in his last 13 games, or a pitcher has a K/9 of 13.4 since June 22nd. Most of the time, the sample is too small, and it’s obviously being cherry-picked for a reason, so there isn’t much significance to it. But even though the data from arbitrary endpoints doesn’t mean a whole lot, there’s still quite a bit of entertainment value, at least for me.

For this reason, I’ve decided to start a monthly series to bring you random Royals stats using arbitrary endpoints. If you follow me on Twitter, you’re going to see them more frequently (read: daily, probably), but we’ll start this series here with a look at the Royals in April, or maybe parts of April. Technically, the Royals did play a game in March, but for brevity’s sake, I’ll refer to the time period in question as April.

- The position player with the highest fWAR in April was Lorenzo Cain, with 0.9 WAR. Cain played in just 12 games.

- Of the 12 hitters who accumulated at least 15 plate appearances, 9 had a wRC+ of at least 96. Only Mike Moustakas, Billy Butler, and Justin Maxwell fell short.

- The only players to post line drive rates above 20% were Omar Infante, Johnny Giavotella, and Maxwell. Gio played in 1 game.

- Conversely, four players had infield fly ball rates of at least 20% – Danny Valencia, Alcides Escobar, Infante, and Salvador Perez.

- During April, Jarrod Dyson swung at just 15.7% of pitches out of the strike zone. Only five players in baseball (minimum 30 PA) had a lower O-Swing%.

- In the last 14 days of the month, Escobar had a wRC+ of 166. Troy Tulowitzki is the only shortstop in baseball who was better (287!!!). Also during that period of time, Mike Trout‘s wRC+ was 169, and Yasiel Puig‘s wRC+ was 165.

- Seven Royals’ pitchers struck out at least a batter per inning during April.

- The Royals’ bullpen threw 67.2 innings last month, and allowed only 2 home runs, both of which were served up by Louis Coleman.

- In 12.1 innings of work, Wade Davis struck out more batters (23) than Bruce Chen in 19.1 innings (18), and Jeremy Guthrie in 32 innings (17).

- In his last 8 outings of April, Davis pitched 8 innings, and all but 5 of the 24 outs he recorded came by way of the strikeout. In other words, he had more strikeouts in those 8 innings than Chen and Guthrie had all month.

- Four pitchers generated infield fly ball rates of at least 11% – Kelvin Herrera, Greg Holland, Yordano Ventura, and James Shields.

- In April, Guthrie allowed a contact rate of 87.9%. Among qualified starters, only the Twins’ Kevin Correia allowed contact more frequently.

- There were 14 pitchers in all of baseball whose average fastball velocity was higher than 95 MPH. The Royals had 3 of them.

- Over the last 14 days of the month, Royals’ pitchers combined for a FIP- of 78, which was the best mark in the American League.

- Over the last 14 days of the month, Royals’ hitters combined for a wRC+ of 99, including a slugging percentage of .402. They had more home runs than the Reds, and as many home runs as the Rangers during that timeframe.

- And finally, a statistic that probably sums up the team’s offense the best: In the first month of the year, Royals’ hitters made contact on pitches out of the zone on 72.4% of their swings. No other team was within 4 percentage points of that figure.

    Hunter those are great, and very interesting numbers for April. Guthrie’s numbers are crazy. I actually like the guy because if he was our #5 pitcher we would be in a really good place, but am wondering if a guy like that has any trade value this year or if it would be best to wait out the year since we don’t have anything right now to replace him. If a team has a run on pitcher injuries, what would they give up for a decent innings eating type of pitcher.

    Crow’s 72% inherited runners scoring is phenomenal all the while keeping an era of zero. The guy is truly trying to make his fellow pitchers look bad. Lets trade him while his ERA still looks good.
