Penn Murfee was mentioned in the interview with Trent Blank that ran here at FanGraphs on Friday. Discussing pitch profiles, Seattle’s director of pitching strategy recalled the erstwhile Mariners reliever being “a guy who had cut-ride” on his four-seam fastball.
Murfee is now with the White Sox, and Chicago’s South Side club is in Boston for a weekend series, so I took the opportunity to get his own perspective on the offering. What I learned talking to him at my home base of Fenway Park is that the movement he gets on his heater is circumstantial. Moreover, it’s legal.
“Back in 2021, in [Triple-A] Sacramento, my pitch profile changed from a running arm-side fastball,” explained Murfee, who was in the Seattle system from 2018-2023, the last year-plus of that span in the majors. “For whatever reason, I started choking the ball a little tight, and began throwing what was classified as a cutter. It went to zero inches of horizontal movement. My pitching coach at the time said, ‘Whatever you changed, don’t change it back.’ He said that I went from having a very average fastball to something unique.”
Welcome to another edition of Five Things I Liked (Or Didn’t Like) This Week. There must have been something in the water across the league over the past seven days, because while this column always highlights delightful oddities that I caught, they aren’t often so delightful or so odd. This week, rarities abounded. There were runners getting hit by throws, wild acrobatics, no-look passes, and even a pitchout. Hot teams and cold teams clashed, errors got compounded, and situations that felt in hand rapidly got away. So keep an eye on the runner at first base, and let’s get started – after my customary thanks to Zach Lowe of The Ringer, who popularized this column format for basketball.
1. Not-Quite-Free Bases Jarren Duran is off to a slow start to the 2025 season. And while the problems have mostly come at the plate, everything seems a little off. Take this misadventure on the basepaths last Thursday. Duran led off the bottom of the 10th inning with a game-tying single. That made him the winning run, and he immediately started plotting a theft of second base to get into scoring position. Nick Sandlin checked on him:
Then he checked on him again:
That’s two disengagements; Sandlin wasn’t likely to try again. Duran stole 34 bases last year. He’s blazing fast. He was 5-for-5 on the season and had already swiped one in this game. Second base was as good as his. And so the Blue Jays took extreme measures, calling for one of the least-used plays in modern baseball, a pitchout:
The Chicago White Sox, coming out of the worst season in modern major league history, started 2025 with a bang: an 8-1 win over the Angels on Opening Day. They lost the next two games, then pounded the Twins into smithereens on the last day of March. Since then, the Sox have dropped 12 games out of 14 and once again settled like silt on the bottom of the American League standings table.
It’s not going to be their year after all. But I don’t think it’s going to be as miserable as it was in 2024, and Chase Meidroth is one reason why. Read the rest of this entry »
Below is an analysis of the prospects in the farm system of the Chicago White Sox. Scouting reports were compiled with information provided by industry sources as well as our own observations. This is the fifth year we’re delineating between two anticipated relief roles, the abbreviations for which you’ll see in the “position” column below: MIRP for multi-inning relief pitchers, and SIRP for single-inning relief pitchers. The ETAs listed generally correspond to the year a player has to be added to the 40-man roster to avoid being made eligible for the Rule 5 draft. Manual adjustments are made where they seem appropriate, but we use that as a rule of thumb.
A quick overview of what FV (Future Value) means can be found here. A much deeper overview can be found here.
All of the ranked prospects below also appear on The Board, a resource the site offers featuring sortable scouting information for every organization. It has more details (and updated TrackMan data from various sources) than this article and integrates every team’s list so readers can compare prospects across farm systems. It can be found here.

I didn’t come close to an answer, because while watching Baz pitch, I was struck by the sparseness of the young right-hander’s uniform. Only three letters in his name; two digits in his uniform number, but represented by skinny numerals. It stood out on the Rays’ classy blue-on-white uniforms. (Some say it’s boring and/or derivative, but I disagree — it’s a color scheme that’ll never steer you wrong in baseball.)
Then I lost the plot a little. The Rays don’t have a jersey sponsor, and their sleeve patch doesn’t contain any script. Their team name is only four letters long. How close does Baz come to having the fewest characters on his uniform of any major league player? Read the rest of this entry »
It’s April, which means that here at FanGraphs we’re contractually forbidden from overreacting to small sample sizes. Overreacting to defensive metrics, which require especially large samples before they stabilize, is an even graver offense, grounds for a written reprimand and public shaming. According to Statcast’s Fielding Run Values, the best non-catcher was worth 16 runs on defense last year. On the other hand, according to Weighted Runs Above Average, the best hitter in baseball was worth 93.8 runs. The sample sizes on defense are a lot smaller and most of the chances are routine, which limits the impact even the best or worst defender can have on the game. However, we’re not forbidden from having fun. Although the small sample sizes make it dangerous for us to draw sweeping conclusions, they make it easy for us to get granular, and nothing says fun like statistical granularity. Today, we’re looking for one thing in particular: specific moments in which we can see a player’s defensive metrics jump or fall by an integer in real time.
Oneil Cruz has already been the most impactful defender according to DRS, racking up a shocking -8 runs over 126 1/3 innings. How did he fall into this abyss? You’d have to dig through every play he’s made this season. It would take a whole article. Maybe I will write that article soon enough, but for now, I’m interested in the other side of the spectrum. Welcome, once again, to Small Sample Size Theater. Read the rest of this entry »
Have you seen all the technological advances taking over pitching in recent years? High-speed cameras, pitching labs, weighted ball training, wind tunnels – maybe the reason we haven’t sent anyone to the moon for decades is that we’re using all the technology to strike batters out instead. Clearly, the arms race (get it?) favors technological savvy and complicated, inscrutable mathematical modeling.
Here’s a counterpoint, though: Maybe you should just throw a fastball and a slider and laugh as batters flail at both. Case in point: Randy Rodríguez has been the best reliever in baseball this year, and there’s nothing fancy about his game. He throws a 98-mph fastball. He throws a tight slider. That’s it – and that’s really all he needs anyway. Through eight appearances this year, he has 13 strikeouts, zero walks, and zero runs allowed.
Oh, two paragraphs don’t make an article? Well then, I guess we should expand on everything a bit. First, his backstory: Rodríguez signed with the Giants in 2017 out of the Dominican Republic and then slowly climbed the minor league ranks. He was a reliever right from the jump, with only occasional dalliances with short-burst starts, and he got a taste of Triple-A in 2022, where he got shelled. He tried it again in 2023 with better results, and by 2024 he looked like he belonged. That was his first year in the upper minors with a single-digit walk rate, and that’s all the Giants were waiting for; they called him up midseason and plugged him into the bullpen.

Erick Fedde returned stateside in 2024 and had a career-best major league season. One year after going 20-6 with a 2.00 ERA for the KBO’s NC Dinos, the 32-year-old right-hander logged a 3.30 ERA and a 3.86 FIP over 31 starts between the Chicago White Sox and the St. Louis Cardinals. His previous big league campaigns had been relatively rocky. From 2017-2022, Fedde fashioned a 5.41 ERA and a 5.17 FIP with the Washington Nationals.
Fedde, whom St. Louis acquired at last summer’s trade deadline as part of an eight-player, three-team swap, entered professional baseball with high expectations. He was drafted 18th overall in 2014 despite having undergone Tommy John surgery during his junior season at the University of Nevada Las Vegas. When our 2017 Washington Nationals Top Prospects list was published in March of that year, Fedde was ranked third in the system, behind Victor Robles and Juan Soto.
What did Fedde’s 2017 scouting report look like? Moreover, what does he think of it all these years later? Wanting to find out, I shared some of what our lead prospect analyst Eric Longenhagen wrote, and asked Fedde to respond to it.
———
“As a junior at UNLV, Fedde was a potential top-10 pick until he blew out in May.”
“Pretty accurate,” Fedde said. “Going into my junior year, I was projected to go at the end of the first round, and just kind of kept climbing as the year went. Unfortunately, I was hurt just before the draft. I think I had TJ two days prior. But it all worked out. I was still able to go in the first round, which was really cool.
“Jeff Hoffman, who was drafted [ninth overall] by the Blue Jays, was kind of the big right-hander ahead of me. He blew out earlier in the year. I think he was kind of up there with me and Aaron Nola at one point. We were looking at possibly top 10, although I don’t know if there was a specific team.”
“Fedde’s fastball mostly sits 90-94 and will touch 96 with a bit of sink and run.”
“I’d say that’s pretty spot on,” Fedde replied. “I didn’t really start throwing hard until that sophomore-to-junior summer; that’s when I started getting up there. I was a consistent 92-93, but the big thing I remember was that I would hold velocity, if not gain it, as the game went on. That’s something I think scouts enjoyed.”
“Fedde’s out pitch is a slider, mostly 81-84 mph, that flashes plus but can get slurvy and lose bite when he doesn’t get on top of it.”
“Yeah, 100%,” he acknowledged. “I think I was throwing a sweeper before I knew what a sweeper was. A couple of years ago that became the total rave — it became the belle of the ball in the sense of pitching — and it’s kind of what I threw. At that time we would call it slurvy, but in today’s world it’s a sweeper.”
“His arm slot can get slingy and low, making it hard for him to drive the ball down.”
“I mean, at that point my life all I did was throw the ball down in the zone,” Fedde countered. “At least mentally, that’s what I was trying to do.”
“Not all scouts are enamored of Fedde’s delivery. His lower half is frail, often unbalanced, and at times plays no role in his delivery at all.”
“I was a thin guy,” recalled Fedde, who now stands 6-foot-4 and weighs 205 pounds. “I think I left for the draft at like 175 pounds. So, I guess I probably relied on whip and quickness instead of strength. I don’t know. Maybe that came into the idea of my having a lack of leg use.”
“If Fedde can improve his currently fringy, mid-80s changeup, he’ll have a viable three-pitch mix and above-average command of it.”
“Yeah, I feel like I’ve always been pretty good with command,” he said. “It’s something that I’ve leaned on throughout my career. The changeup really stunk all the way up until a couple of years ago. So that’s very true. I finally feel like I have a decent changeup. And then, as I got into pro baseball, I learned a cutter to add to my mix. Now it’s a four-pitch mix.”
“He projects as a sinker/slider mid-rotation arm.”
“I think it’s been kind of east-to-west that way,” Fedde said. “I’ve been in the middle of rotations. I definitely would never say that I’ve been a number one. But yeah, just keep growing and hopefully push to the top end of rotations. Last season was my best so far, for sure. I had a lot of struggles early, a lot of learning. But like [the scouting report] said, if I can get a good changeup… I mean, I think the changeup really changed my career.”

Hitting a baseball is an unthinkable accomplishment of timing. In order to strike a ball traveling from the pitcher’s hand to the plate in less than half a second with a slab of wood, a hitter must execute an elaborate sequence of movements on time. When do you lift your front foot? When do you load your hands? When do you fire your hips? It’s a sophisticated choreography; a beat late at any point can doom the swing.
Picture Fernando Tatis Jr. When Tatis is at the plate, he shifts around like a predator stalking its prey, eyes peeled for the exact moment when the pitcher lifts his front foot so that he, too, can get his toe down at the right time, and then his hands up, and then finally the barrel through the zone:
If hitting is such a delicate sequence, conditional on the pitcher’s own timing, it follows that pitchers who mess with that timing can improve their performance; by extension, pitchers who groove their deliveries will underperform their stuff. In an interview with David Laurila in 2017, Jason Hammel described changing his delivery for these precise reasons. Read the rest of this entry »
Nick Sandlin didn’t get his second save in as many games on Thursday. One day after breezing through three Boston batters on nine pitches, the Toronto right-hander was tagged with a loss after surrendering a pair of bottom-of-the-tenth-inning runs. The ending was anomalous. With the score tied, one out, the bases juiced, and the infield playing in, Sandlin induced a squibbed grounder that was mishandled, allowing a speedy Red Sox runner to score easily from third.
Making the walk-off unique was that Blue Jays second baseman Andrés Giménez, who had no chance to get the runner at home after bobbling the ball, threw to first for a meaningless out. The play went into the books as a 4-3. In other words, the game ended with the winning run crossing the plate on what looks like a routine groundout on the scorecard.
Which brings us to Sandlin, whom I’d decided to write about after his shutdown effort on Wednesday. Protecting a 2-1 lead in the 11th inning, the 28-year-old reliever fanned David Hamilton on three pitches, retired Rob Refsnyder on a pop foul to the catcher, then got Jarren Duran to slap a worm-killer to Giménez. Sandlin’s pitch breakdown comprised two splitters and seven sliders.
A sweeping slider is Sandlin’s bread and butter, and it’s what Refsnyder referenced when I asked him what makes the low-slot hurler so hard to hit. Read the rest of this entry »
