Sunday Notes: Walter Pennington Ponders His Zero-Zero Slider
Shortly before Walter Pennington was acquired by the Texas Rangers from the Kansas City Royals at last month’s trade deadline, Eric Longenhagen wrote that the 26-year-old left-hander had “caught some helium of late after striking out 35% of the hitters he’s faced in Triple-A.” Our lead prospect analyst went on to note that Pennington had recently made his MLB debut, adding that he “has a middle relief profile with little margin for error due to his underwhelming velocity.” Longenhagen assigned the 2020 non-drafted free agent out of the Colorado School of Mines a not-overly-enthusiastic 35+ FV.
Through his first seven big-league appearances — one with the Royals and now six with the Rangers — Pennington has fanned 10 batters and allowed three earned runs while attacking hitters with an array of sinkers, sliders, and cutters (he’s also thrown a smattering of four-seamers) in eight-and-two-thirds innings of work. Down on the farm, he’d heavily featured his slider while fanning 82 batters and allowing 43 hits in 63-and-a-third frames.
His velocity is indeed underwhelming. And not only has Pennington been averaging just 91.7 mph with his heaters, his arsenal doesn’t include a breaking ball that sweeps or dips in eye-catching fashion. Your stereotypical power pitcher he’s not.
Asking Pennington how he profiles on the mound elicited some intriguing answers.
“I’m not [a power pitcher], but I think I’m the best pitcher in the world,” Pennington told me when the Rangers visited Fenway Park earlier this month. “You have to tell yourself that always. Right? You have to be confident out there. But I like to say that I’m a movement guy who mixes his pitches well. When I throw the ball, I see the ball move. The way I perceive myself throwing isn’t really what the numbers say, though.”
Pennington has a degree in mechanical engineering, so it’s not as though he lacks reasoning skills. I asked if he could elaborate.
“When I throw the ball, I see my slider move sideways when the numbers say it’s zero-zero; it’s usually around there horizontally and vertically,” explained Pennington, who throws from a low three-quarters slot. “But while the numbers say it’s nothing special, when I talk to hitters they say it’s really deceptive. Michael Massey called it looking like a lacrosse ball coming out of my hand. So, I don’t really know why my slider is good except for there being something in the way that my body works and how I throw. I’ve heard that I hide the ball well.”
As you might expect, the difference in movement between his sinker and go-to slider is a big part of why each pitch is effective. Pennington told me that his sinker typically gets “negative-nine vertical and between 10 and 15 horizontal,” giving him a good bit of separation from the zero-zero slider. There is velocity separation as well, with the slider averaging 83.9 mph.
That Pennington once thought that it would be necessary to add movement to his slider is another part of the story.
“When I was first throwing with a Rapsodo we didn’t know much and it was like, ‘This thing’s not moving at all; it’s like a straight knuckleball,’ recalled Pennington. “We thought we needed to change some stuff, so I started trying to throw it more like a curveball. But again, even though metrically it isn’t anything special I’m still getting swing-and-misses. It doesn’t make sense — why does my stuff play well when numerically it’s nothing special? — but it works. As long as hitters can’t figure it out, I’m going to keep going with it.”

Why Josh Hader’s fastball is elite is fairly well known. The 30-year-old, left-handed closer throws a high-velocity two-seamer which, thanks largely to his arm slot and release height, doesn’t act like a two-seamer. As Travis Sawchik wrote at FiveThirtyEight back in 2019, Hader’s heater is “something of a ghost pitch: It’s very difficult to hit but not for any of the usual reasons.”
I recently asked Hader when he first learned the why behind the “wow.”
“I learned the vertical approach stuff probably my second year in pro ball,” replied Hader, who was drafted by the Baltimore Orioles in 2012 before going on to dominate hitters with the Milwaukee Brewers, San Diego Padres, and now the Houston Astros. “But it’s not something where I had to chase anything, because I already knew that I got a lot of swings-and-misses at the top of the zone. I already threw the ball up, so nothing changed.”
Hader’s slider has changed. That happened prior to last season, the intent being to help it play better off of his fastball.
“We made it more of a gyro,” explained Hader. “I have a guy I talk to named Ben [Brewster] — he’s at Tread — and what I’ve learned is that when you have a big-shaped slider it gives the hitter a little more time to adjust to that pitch. It’s easier for them to wait on it.”
Hader added that he wanted to have a slider similar to Jacob deGrom’s, and while he “has no idea how similar it actually is,” he did succeed in altering the shape in a productive manner. A baby spike with his index finger helped him create the gyro spin he was looking for.

Which of Francisco Lindor, Ketel Marte, Shohei Ohtani, or Marcell Ozuna would get your National League MVP vote as of right now? I asked that question in a Twitter poll on Friday, and the result was a landslide win for the Los Angeles Dodgers superstar. Should it have been?
Here are a few of their numbers as of the time the poll went up:
Lindor: 6.3 WAR, 133 wRC+, 25 HR, 73 RBI, 25 SB.
Marte: 5.4 WAR, 152 wRC+, 30 HR, 81 RBI, six SB.
Ohtani: 6.0 WAR, 169 wRC+, 39 HR, 88 RBI, 39 SB.
Ozuna: 4.4 WAR, 165 wRC+, 37 HR, 94 RBI, no SB.
As for the poll results, Ohtani garnered a hefty 73.0% of the votes cast, while Lindor got 17.0%, Marte 6.0%, and Ozuna 4.0%. While I expected Ohtani to come out ahead — and it is understandable that he did — the margin of victory was somewhat more than I expected. The inevitability of 40/40, which he proceeded to reach on Friday evening, certainly played a big role. Historic achievements carry a lot of weight.

A random obscure former player snapshot:
Kewpie Pennington’s lone big-league appearance came in a notable game. His own performance was unremarkable — the right-hander surrendered a single to Happy Felsch, then retired the next three batters — but the knock he allowed was one more than his teammates logged all day. The April 14, 1917 contest saw Chicago White Sox hurler Eddie Cicotte, who was later banned from baseball due to the Black Sox scandal — toss a no-hitter. Pennington had neither glory nor infamy in his career, although he did have a handful of solid seasons down on the farm. He went 16-10 with a 1.60 ERA for the Hartford Senators in 1920, and he followed that up by going 18-12 with a 1.84 ERA in 1921. His given name was George.

Craig Counsell shared an insightful perspective when addressing expectations for individual players. He used Justin Steele as an example.
“The nature of the game is that you have to prove it, you have to prove it, you have to prove it,” the Chicago Cubs manager said prior to the southpaw’s last start. “You’re always required to do that. Justin is going to be required to do it again. Like, OK, so what? Do it again. That’s kind of how you have to look at it.”
Steele made 30 starts last season and logged a 3.06 ERA and a 3.02 FIP. So far this season — including Thursday’s outing — he has made 21 starts and logged a 3.07 ERA and a 3.18 FIP.

A number of great quotes are attributed to Yogi Berra, such as “It ain’t over until it’s over” and “You can observe a lot just by watching.” Prior to Wednesday night’s game against the Chicago Cubs at Wrigley Field, Detroit Tigers manager A.J. Hinch supplied a Yogi-ism of his own when addressing what he wants to see from his young players in the final month-plus of the season.
“We want to see consistent performance, and that doesn’t always mean 2-for-4 every game,” Hinch told a small group of reporters. “It doesn’t mean box scores. It means baseball aptitude. It means baseball awareness. They’re learning how to play, and make winning plays.”
The veteran manager went on talk about seeing how young players respond to success and failure, as well as the adjustments they make both on their own and through the help of coaches. Then came the Yogi-ism.
“The success component of it is not just meant for the box score,” said Hinch. “We want as much box score success as we can get, because we’ll have scoreboard success when we get box score success.”

RANDOM FACTS AND STATS
Following their game on Wednesday, the Chicago Cubs and Detroit Tigers both had records of 62-65. The Cubs had scored 527 runs and allowed 527 runs. The Tigers had scored 527 runs and allowed 526 runs.
From 1906-1910, the Cubs went 530-235 with seasonal win totals of 116, 107, 99, 104, 104. Their .692 winning percentage is the highest ever in MLB history over a five-year span. They played in four World Series, winning two and losing two.
The Chicago White Sox have lost 21 of the 22 games Michael Soroka has appeared in this season. The 27-year-old right-hander is 0-10 with a 5.23 ERA.
The New York Yankees scored 10 or more runs 41 times in 1936. They went 40-1 in those games with the only loss a 12-11 walk-off in Philadelphia against the Athletics.
Stephen Smitherman smacked his lone big-league home run on today’s date in 2003 as the Cincinnati Reds dropped a 10-6 decision to the Milwaukee Brewers. The dinger, which was also his first hit — Smitherman went 7-for-44 in his 21-game MLB cameo — came as a pinch-hitter.
On today’s date in 1922, the Philadelphia Phillies scored eight times in the eighth inning and six times in the ninth inning… and lost to the Chicago Cubs 26-23. The teams combined for 51 hits, 21 walks, and nine errors. Time of game was 3:01.
The St. Louis Cardinals and Houston Astros played to a 3-3, rain-shortened 10-inning tie on today’s date in 1975. Cliff Johnson homered in the top of the 11th to give the Astros a 4-3 lead, only to have the blast negated; per the rules in place at that time, if an inning was not yet complete the score would revert back to the last completed inning. Had it counted, Johnson would have had a home run in his sixth consecutive game.
Players born on today’s date include Dick Rudolph, who was the winning pitcher in both Game 1 and Game 4 as the Boston Braves swept the Philadelphia Athletics in the 1914 World Series. The right-hander went 26-10 with a 2.35 ERA for The Miracle Braves (they were in last place on the Fourth of July) that season.
Also born on today’s date was Rufus Meadows, who in 1926 retired the only batter he faced in what was to be his lone big-league game. Eighteen years old when he took the mound for the Cincinnati Reds, the southpaw from Chase City, Virginia induced a ground-ball out in an 18-1 loss to the Chicago Cubs.

“The Chicago White Sox have lost 21 of the 22 games Michael Soroka has appeared in this season. The 27-year-old right-hander is 0-10 with a 5.23 ERA.”
They have been a much better team without him going 4-28 since his last appearance on July 14!
It is hard to process how awful this season has been for the Whitesox.
The rot goes so deep. They don’t have a single position player who has played in the majors this year who looks like they are a long-term solution. Miguel Vargas, Oscar Colas, Zach DeLoach, Dominic Fletcher, Lenyn Sosa, Braden Shewmake, Bryan Ramos, and Gavin Sheets are all at or below replacement level on the year.
The pitching side is a little better, with Jonathan Cannon looking like he might be a 4th starter, but Ky Bush, Jared Shuster, and Nick Nastrini have also been bad. Even Drew Thorpe has been replacement level.
There are a few guys that will probably have some trade value this offseason (Crochet) or eventually (Robert, maybe Vaughn). And there are a handful of legitimately exciting prospects in the minors like Schultz, Quero, and Hagen Smith. But right now there are maybe 3 or 4 players on this team that could be a starting pitcher or be in the starting lineup for a .500 team like the Tigers, Cardinals, or Giants, and except for potentially Cannon none of them are going to be here when the team is good again.
I watch that team hit and am amazed at how pure their talent is. Maybe Baldwin and Lee can become something. Vaughn isn’t a finished product yet. Vargas has always given me David Villar vibes.
On the mound when I squint I can see potential in Davis Martin, Thorpe, and the aforementioned Cannon.
When they deal Robert and Crochet they better nail the returns.
Martin and Thorpe are big “maybes” at this point but I do like Thorpe. And Martin could be a #5, which is a whole lot better than Soroka or Ky Bush.
If I had to guess I’d say that all of Baldwin, Lee, and Vargas are going to be busts but they don’t have anyone standing in their way so you might as well give them a shot.
Baldwin probably has the best chance to be a real contributor because he can play shortstop. Gives the bat a lot more margin for error. Montgomery is probably not a shortstop and Gonzalez is struggling in AA, so he’s got more time to establish himself.
I suspect that Vargas is going to be supplanted by Montgomery at third base and that he won’t hit well enough to profile anywhere else. Montgomery has had a bad year but he’s still got more promise than Vargas. I think Lee is going to be a backup catcher at best and that Quero will be a much stronger option for the White Sox.
Vaughn is a non-tender candidate but if I were the White Sox I would see if he would take a deal to stay at his current salary for 2025 to see if he bounces back even a little. He’s not a long-term solution with only two more years of team control but he might rebuild enough value for someone to trade for him. Not likely, but possible. And–I can’t believe I am saying this–even as a replacement-level player he has value for the White Sox. They have zero position players in the minors who look like they will hit well enough for 1B, Gavin Sheets cannot hit left-handed pitching at all, and it doesn’t make sense to spend more than about $3.5M on a 1B with how bad the rest of the team is.
Depending on his salary I could see a contender dealing for Vaughn this offseason. Houston makes sense.
They have employed three pitchers named Michael this year. They are a combined 2 – 21.
They suffered their 99th loss yesterday. It is nigh impossible for them to not lose 100 games before September 1st.
But Chris Getz is here because the owner thought if he brought someone in from outside it would take longer to turn things around.
I love parsing stuff out like this.
Here’s another perspective. The White Sox are 18-86 in games not started by Fedde or Crochet. That’s a .173 percentage! I would have that would be inpossibly bad for a sample size that large but I would be wrong.
They did it! Fastest team to 100 losses since the 1916 Philadelphia Athletics and only the fourth team ever to do it before September 1st.
They are easily on pace for most losses since 1900 and have a shot at the lowest winning percentage.
And yet somehow the Guardians are only 5-5 against the White Sox with a +3 run differential. Did someone forget to tell the Guardians how bad the White Sox are???
No, they just forgot how bad their starting pitching is this year until Chicago reminded them.
Not that the rest of us needed reminders, except the Dolans, apparently.
