It feels like the season is winding down, but there are still two-plus months left so we will still see plenty of minor leaguers come up and get a shot. Today I want to look at a group of K-BB% leaders who haven’t appeared in the majors yet (min. 70 IP at Double- and Triple-A).

Nabil Crismatt, SEA – 24% K-BB

The 24-year old started his big season in Double-A and has definitely slowed down in Triple-A, despite still striking out 34% of the batters he’s faced in 22 innings there. I’ll defer to Alex Chamberlain for more info on him as he recently featured Crismatt in a Peripheral Prospects piece.

Alex Faedo, DET – 23%

Faedo has improved in a repeat of Double-A, jumping in K-BB% from 15% to 23%. He was ranked 15th in the Detroit prospect list this spring, but these 99 innings have helped his outlook. While he hasn’t hit Triple-A, he might not need much time there before getting a look in the majors. He and the next guy on the list both appeared in Peripheral Prospect 1.13.

You may or may not have heard that Yu Darvish is back. By any conventional measure, his latest back-to-back starts of six shutout innings, two hits, and seven-plus strikeouts rank among his best in a long time. By measure of “Game Score v2,” which FanGraphs includes in a pitcher’s Game Log, Darvish’s scores of 78 and 79 are his two best starts since 2017. Because some of his better Game Score starts went more than six innings: these are his two best six-inning starts, period. They happened very recently, consecutively, and he didn’t labor through them, either, throwing just 94 and 83 pitches, respectively.

The last two starts were a gift to those who took a leap of faith. Darvish, who walked at least three batters in seven of his first eight starts (33 walks in 36ish innings!) and 10 of his first 13 (44 walks in 66ish innings!), was an absolute mess. He had compiled a 4.88 ERA, 5.19 FIP, 4.49 xFIP, and 4.96 SIERA in 13 starts, the cherry on top being a walk rate (BB/9) of six. Six! Six batters per nine innings. As my 14-year-old self quoting Ron Burgundy might say: “I’m not even mad — just impressed.”

However, from June 10 to July 3 — a five-start window sandwiched between his early-season futility and his recent wizardry — Darvish struck out 33 and walked just five in roughly 31 innings, compiling a 3.68 xFIP and 3.64 SIERA. Read the rest of this entry »

Where would those of us who are passionate about full-season Fantasy Baseball be without the counsel of America’s Leading Fantasy Sports Aggregator to guide us? Our hearts accordingly leapt up when we beheld in our In Box last week ALFSA’s “Ten Bold Second Half Predictions.” And about whom were these predictions predicted? Here’s the full list: Matt Olson, Christian Yelich, Justin Smoak, Pete Alonso, Kenta Maeda, J.D. Martinez, Brandon Woodruff, Mookie Betts, Jackie Bradley, Vladimir Guerrero Jr., and Eloy Jimenez.

Thanks, podnuh; we’ll rush right out and grab all those guys. Look—as we see it, a Bold Prediction must also be a Useful Prediction, and for anyone in a redraft league, a Useful Prediction is one involving a player who might actually be available. With this in mind, we present our own Bold Second Half Predictions, confident that most if not all these guys will be available for cheap in most if not all leagues. Five pitchers today, then five hitters tomorrow: Read the rest of this entry »

Trade season kicked off with a couple of smaller moves over the weekend as Boston and Oakland bought in on a pair of once-solid arms trying to recapture their past glory. While the deadline isn’t loaded with top-flight players, we could still see a blockbuster trade period by volume. Of course, that second wildcard keeps a lot of teams thinking they are alive when they really aren’t legitimate contenders… lookin’ at you, San Francisco.

Just about every league has a Mike Soroka owner. Then again, the Braves’ All-Star rookie landed at the break as a top 20 starting pitcher in Roto value. He has the fifth-lowest ERA (2.42) and 13th-lowest WHIP (1.05) among all pitchers with at least 80 innings, and 6.0 runs of support per nine innings has left him with a dazzling 9-1 record.

Soroka also ranks seventh in sinker usage with a 47.4 percent rate. His primary offering is, in general, a notoriously bad pitch for swings-and-misses and not especially good for limiting extra-base hits. As one would expect from a pitcher who uses a sinker nearly half the time, Soroka has been below average at getting strikeouts. While the major league average K% is 22.8 percent, Soroka has registered a 20.1 percent rate in the first half. When you consider that many of the below-average strikeout pitchers are left unowned in many leagues, Soroka has been something of a liability for strikeouts for fantasy owners.

Since 2013, I have polled you dashingly attractive readers on which group of pitchers you think will post the better aggregate ERA post all-star break. The two groups were determined based on ERA-SIERA disparity, pitting the overperformers versus the underperformers during the pre-all-star break period.

In 2018, and again earlier this year, I reviewed how different pitch types perform by various measures including swinging strike rate (SwStr%), ground ball rate (GB%), and isolated power (ISO). In the last couple of years I have tried to emphasize heavily the importance of evaluating a pitcher on his component parts — namely, each of his unique pitches, all of which behave differently and can bring resolution to some of pitching’s more enigmatic questions and issues.

If you clicked through those links in the first sentence, you saw how breaking balls and offspeed pitches outperform fastballs by virtually every metric. With the advent of Statcast, we can not only validate my prior work, which relied on PITCHf/x data, but also dig more deeply into how each pitch type behaves according to newfangled Statcast data — namely, how each pitch performs exclusively on balls in play.

This is something I pursued preliminarily using the PITCHf/x data, by measure of ISO, but it doesn’t fully capture total production or damage allowed. Having written about Zack Wheeler the other day and in discussing how the performance of his pitches have ebbed and flowed from 2018 to 2019, I was curious to dig into pitch-specific expected weighted on-base average (xwOBA) on contact (xwOBAcon).

Here’s how every pitch type compares by xwOBA allowed. Keep in mind, xwOBA captures “deserved” total value through not only balls in play but also strikeouts and walks. Year in and year out, fastballs fare worse than the league average, whereas breaking balls and offspeed pitches perform better than average, all to varying degrees.

Zack Wheeler, prior to about two weeks ago, was an enigmatic starting pitcher on whom many fantasy owners had started to lose faith. (Such faith might again be lost after Sunday’s start, which is another issue all together.) After missing two seasons recovering from Tommy John surgery and related setbacks, Wheeler returned to the mound in 2017 only to be sidelined once more and miss almost the entire second half of that season. The prospects of him succeeding in 2018 were, frankly, not great.

Wheeler, however, came out firing, his four-seamer and two-seamer averaging 95.9 and 96.1 mph, respectively, up from 94.8 and 94.3 mph — a moral victory in its own right. The added velocity helped both pitches play up in way completely unseen the year prior, as measured by expected weighted on-base average (xwOBA) allowed:

Pitchers who are adept at getting swinging strikes but not strikeouts are one of fantasy baseball’s mild annoyances. Many of us have used SwStr% as a shorthand for strikeout potential, but a few pitchers with high whiff rates fail to meet our expectations, usually because they get called strikes at a low rate. Prior to this season, Jake Odorizzi was one of those pitchers. Joe Musgrove (11.3 percent SwStr%, 19.3 percent K% in 2019) still is.

Eduardo Rodriguez does not fit this category exactly, but in the context of his past performances, he seems to be a strikeout underachiever this year. The Red Sox’s lefty entered this season with back-to-years of a SwStr% above 11 percent, outpacing the major league average for starters by more than a percentage point in both campaigns. His strikeout rates were far above average: 25.8 percent in 2017 and 26.4 percent in 2018. Yet Rodriguez achieved these rates with below-average called strike rates, with a 16.7 percent mark in 2017 and a 15.3 percent rate last season.
