On Monday night, the Rockies lost to the woeful Cubs, 6–4. It brought their road record to 14–46, good for a .233 winning percentage. That’s the worst mark in baseball, but the Rockies aren’t the worst team in baseball — merely the worst road team. At Coors Field, they’ve gone a spectacular 43–22, the third-best home record in the game.

It’s hard to imagine that this huge discrepancy comes down to a roll of the dice. Are the Rockies this bad on the road? Probably not. Are they this good at home? Also probably not. But this gap calls out for an investigation, so I set out to answer: what in the heck is up with their home field advantage — if that’s even what’s going on here?

Obviously, I’m not the first person to try to answer this; earlier this year, Neil Paine tackled the subject when Colorado was a woeful 6–32 on the road. The Coors hangover effect is real, and it gives us a good reason to think that the source of the Rockies’ problems might be the road side of things rather than the home side of things. I won’t try to solve the issue of what ails the Rockies today, but still, we can gawk at their incompetence and speculate about what it means for their true talent, which sounds fun enough to me.

Whether it’s because they’re only just getting healthy or someone ahead of them has gotten hurt or their talent is kicking down the doors of roster manipulation made brittle by actual competitive spirit, some potentially important participants in postseason play are currently in the minors as we speak. This is especially likely when it comes to pitching, where health and effectiveness are tenuous, and team behavior surrounding promotion tends to be more opportunistic and aggressive.

For both leagues, I’m providing a scouting-centric update on pitching currently in the minors, either because the players are prospects who could conceivably play a September role or make a postseason roster, or because the player in question is a rehabbing big leaguer. Pitching can be streaky and fragile, so any of these guys could be in the big leagues at the drop of a hat, or they may simply convince their front office, like several rookies did last year, that they’re one of the best 26 guys in the org and need to be put on the playoff roster. The level of impact could range from Hunter Greene or Shane Baz dominating like Francisco Rodriguez in 2002, to Connor Seabold or Thomas Hatch humbly eating innings in a blowout loss in effort to save the rest of the bullpen for the series’ next game like J.A. Happ in 2008.

I’ll touch first on the American League this week, then provide some National League options next week. If any prospects moved on The Board due to info or opinions brought to light from this piece, I’ll note that below.

Taylor Hearn has added a pitch to his arsenal. More specifically, the 26-year-old Texas Rangers southpaw has reintroduced a pitch that he’s throwing in a notably different way. Unveiled mere months ago, it’s a potential career-changer.

Recently moved from the bullpen to the Rangers’ starting rotation, Hearn discussed the pitch when Texas visited Boston this past weekend.

———

David Laurila: You’ve added a sinker to your repertoire. Was that a simple matter of wanting to induce more ground balls?

Taylor Hearn: “Honestly, I was getting ground balls, It was a pitch I’d thrown before, and I kind of wanted to learn it again but in a different way. I’m always trying to figure out what I can add to my repertoire, whether it’s a curveball or whatever else.”

Laurila: When had you thrown a sinker?

Hearn: “I had it when I came over here, to [Double-A] Frisco [from the Pirates via trade in July 2018]. I wasn’t really throwing it too much, and it wasn’t really even a sinker — it was just a regular two-seamer — and it just didn’t have the movement, because I’d never really had anybody teach me that. This year, I asked about throwing a sinker. They showed me one, I threw it, and we got numbers I’d never had before. I decided to run with it.”

Laurila: Was this in spring training?

Hearn: “No, this was actually during the season. I started throwing it in Minnesota [in early May]. The first game I threw it in was away, against Seattle [in late May].”

Laurila: How does it differ from your old two-seamer? Read the rest of this entry »

The Astros bludgeoned the Mariners on Saturday in a game that was over by the time the fifth inning was complete, when Houston owned a 12–0 lead and win probability odds of 99.9% (the final score was 15–1). That game marked the 19th time in August that a team had won a game by at least 10 runs, the most in any month so far this season — and we still have a week left to go before September. Naturally, the non-contenders that sold at the trade deadline or sat still have different priorities at this stage of the season compared to the postseason hopefuls. But how much of an impact does the deadline have on the game’s competitive nature?

You could try to measure this with run differential. Prior to the trade deadline, the average margin of victory in a game was 3.54 runs; since then, it’s gone up to 3.75 runs. But the average increasing by a mere 0.2 runs per game is not a monumental change. Similarly, you could look at two teams that held deadline fire sales — the Cubs and Nationals — and look at their post-July 31 performance. Chicago is down three runs and the Nationals 1.2 in terms of run differential per game, almost entirely due to pitching and defense. But those are extreme examples, and aside from Max Scherzer and Craig Kimbrel, the impact talent that both dealt away was mostly on the position player side.

Rather than just rely on anecdotal evidence, let’s take a probabilistic look at these outcomes. To test whether or not there is statistical evidence for the trade deadline creating measurable disparity, we’ll form two sets of discrete probabilities: one based on games through July 30 (prior to the trade deadline) and one based on games afterwards. Any games with a resulting run differential of greater than or equal to 10 runs will be grouped together.

Given the small increase in average run differential between the two periods, it’s no surprise that any change in probabilities is pretty small. But focusing on the left and right boundaries, you can see the differences that we’re looking for. While one-run games are still the most common, they’re happening a bit less frequently than they were before the deadline. The incidence of games decided by at least 10 runs, meanwhile, has gone from 3.9% of games pre-deadline to 6.0% after it. (Interestingly, run differentials in between the extreme values are pretty mixed.)

Monday night brought something unseen in the majors since September 7, 1901: a matchup between two teams on winning streaks of nine or more games. In this case, both the visiting Yankees and the hosting Braves were riding streaks of exactly nine wins, and it was New York who prevailed with a 5–1 victory.

Monday’s game also brought something with only slightly more precedent: the fourth appearance by the tallest outfield in AL/NL history, one made possible by the Yankees’ aggressive approach at the trade deadline and their momentary good fortune when it comes to injuries. Their lineup featured 6-foot-5 Joey Gallo in left field, 6-foot-7 Aaron Judge in center, and 6-foot-6 Giancarlo Stanton in right, each of whom figured significantly in the team’s win. That trio of elite power hitters has played a played a prominent role in helping the Yankees blow past the Red Sox, A’s and Mariners to the top of the AL Wild Card standings.

Facing the Braves’ Huascar Ynoa at Truist Park, Stanton swatted an opposite-field solo home run in the second inning to give the Yankees a 1–0 lead, then added a two-run double that scored both DJ LeMahieu (who was hit by a pitch) and Gallo (who walked) to break a 1-1 tie in the sixth. His first drive left the bat at 103.4 mph, his second at a scorching 119.2 mph:

The Yankees extended the lead against Edgar Santana in the eighth via a two-out Judge single, walks by Gallo and Luke Voit, and then a two-run single by Gary Sánchez, effectively sealing the game. Gallo, meanwhile, had the defensive play of the night via his diving catch of a Guillermo Heredia drive in the second inning:

Judge traveled a long ways — 87 feet, according to Statcast — to haul in Jorge Soler’s fly ball in the third:

Quipped Yankees manager Aaron Boone afterwards, “It’s nice to see the jumbo package out there playing really well.”

The Jumbo Package, or the Big Boy Outfield, or the Large Adult Sons of Brian Cashman — by whatever name, this is the tallest outfield in major league history, at least going by the listed heights at Baseball Reference. Those measurements may contain their share of fudge, but unless you’ve got a tape measure, that’s the best we’re going to do.

Walker Buehler has been on a tear in the second half, leading all pitchers in WAR since the All-Star break at 1.8, just a hair ahead of Adam Wainwright, Frankie Montas, and Max Fried. For the season, he now ranks fourth in WAR among qualified starters (fifth if you include Jacob deGrom’s 92 preposterous innings), toting a 26.9% strikeout rate and a park-adjusted ERA 47% better than league average. His 2.11 ERA is more than half a run better than any other season in his career, and the park adjusted figure is his best by 15 points. It’s another great season from one of the consistently best pitchers in the majors; since becoming a full-time starter for the Dodgers back in 2018, Buehler has posted the 11th-most pitching WAR with the 19th-most innings pitched.

I am not breaking any news by pointing out that Buehler has been and continues to be excellent. The surface-level numbers indicate he has never been better. What caught my eye, however, was how he has gone about doing that. There have been some noticeable changes under the hood. For example, at age 26, he has lost over a full tick of velocity on his fastball compared to any prior season; based on my own research, you would expect a player of his age to lose only about 0.15 mph.

Buehler has also lost almost two percentage points on his strikeout rate. On its face, missing less bats and losing velocity is never something you want to see in a pitcher. (That said, he has brought his ground-ball rate back to pre-2020 levels, going from 35.5% last season to 43.8% this year, similar to his ’19 rate as well as a tick above the rest of the league in 2021.)

Jimmy Kerr is pretty low-profile as far as prospects go. The 24-year-old infielder was a 33rd-round senior-sign in 2019 and currently playing for the Detroit Tigers’ High-A affiliate, the West Michigan Whitecaps. A standout during the College World Series in his draft year, he remains relatively unknown beyond the University of Michigan, where he earned a degree in Industrial Operations Engineering.

His knowledge of hitting promises to increase his profile. Kerr faces long odds to reach the big leagues, but he’s already begun gaining a foothold as an instructor. Last year, he co-founded K2 Baseball, an elite training facility in Ann Arbor, Michigan.

Kerr talked hitting prior to a Whitecaps game earlier this month.

———

David Laurila: Let’s start with your training facility. How did that come about?

Jimmy Kerr: “It was over the pandemic. A couple of my college teammates and I were up in northern Michigan — my parents have a place in Walloon Lake — kind of escaping for the summertime. We were working out at the local high school, trying to stay in shape, and had also ordered some workout equipment. Everybody was trying to start their own home gym at that time, so it was backordered and took awhile [to arrive].

“Once the weather turned and guys were going back to school, we rented out a space in Ann Arbor and put all the workout equipment in there. We put in a batting cage, turf, a portable mound, and started running a little baseball facility. It started with just some of our Michigan teammates who are in pro ball now, and then we turned into a business where we’ve got high school kids and youth baseball players. We’re doing training programs, lessons, and all that.”

Episode 937

FanGraphs Audio is here a bit early this week, featuring a combined interview with a surging Rays prospect and his own radio broadcaster.

David Laurila welcomes Taj Bradley, a 20-year-old right-hander whose strong year saw him promoted to High-A, and Shawn Murnin, the voice of the Bowling Green Hot Rods. The trio discuss things like famous baseball alumni from their former clubs, staying in shape with no minor league season last year, and learning Australian slang from teammate Curtis Mead. Bradley also shares how he learned to pitch relatively late, and Shawn tells us about getting to travel with the team again and what it was like to cover Wander Franco.

As the schedule hurtles towards the final month of the season, most of the division races have sorted themselves out. The real drama is in the Wild Card races in both leagues, with a handful of teams in each fighting over those last two playoff spots.

A quick refresher: my Power Rankings approach takes the three most important components of a team — their offense (wRC+), and their starting rotation and bullpen (50%/50% FIP- and RA9-) — and combines them to create an overall team quality metric. I add in a factor for “luck” — adjusting based on a team’s expected win-loss record — to produce a power ranking.

The Giants and Dodgers continue to elevate themselves over everyone else in baseball. Over the last two weeks, Los Angeles has gone 11–2 and closed the gap with first-place San Francisco to 2.5 games. The only shame is that they’re on course for a first-round matchup in the playoffs; whoever wins the wild card will end up playing whoever doesn’t win the NL West in the win-or-go-home matchup. For the Dodgers, Trea Turner has been a catalyst atop their lineup, but Max Muncy has been driving their offense recently, launching six home runs in August and putting himself into the NL MVP conversation alongside Turner. Those two are just a decimal point behind Fernando Tatis Jr. for the WAR lead in the NL.

The Giants continue to get phenomenal contributions from their pitching staff. Even though Anthony DeSclafani just landed on the Injured List with an ankle injury, Logan Webb is primed to pick up a lot of the slack. He hasn’t allowed more than two runs in a single start since a six-run blowup in Colorado on May 5. San Francisco’s lineup has also gotten a lot healthier recently, too, with Brandon Belt, Evan Longoria, and Tommy La Stella back from their respective injuries.

These are notes on prospects from Tess Taruskin. Read previous installments of the Daily Prospect Notes here.

This past weekend, I made my way up to Wisconsin to get my first look at some recent Marlins and Cardinals High-A promotions. The fact that both organizations’ respective Low-A affiliates play home games in ballparks for which we have access to Statcast data makes these looks particularly exciting, as it affords us the opportunity to place them into a more robust context.

Eury Perez, RHP, Miami Marlins
Level & Affiliate: High-A Beloit Age: 18 Org Rank: 8 FV: 45
Line: 5 IP, 3 H, 3 R, 6 K

Notes
The buzz in the crowd at Saturday’s game was likely due to it being the debut weekend for Beloit’s brand new ballpark, but it could just as easily have been thanks to the young righty making his debut on the mound for the Snappers against Peoria. Just 18 years old, Perez is the youngest player at High-A, but he’s already earned himself a reputation as one of the most exciting pitching prospects in the Marlins’ system. After standing out at Miami’s instructs, the righty put together a spectacular season at Low-A Jupiter; opposing batters hit just .163 against him in his 56 innings of work with 82 strikeouts, 21 walks, and just two home runs, good for a 1.61 ERA and a 0.95 WHIP.

Perez’s best performance came earlier this month, when he struck out 11 batters in 4.1 innings against Low-A Tampa, which boasts the best record in the division and a staggering +245 run differential this season. He held the Tarpons’ lineup hitless, posting a 50% whiff rate and a CSW% of 42%, and his velocity sat 93–96 mph. That is up from the 91–95 seen at instructs and more or less on par with where he sat throughout his time in Jupiter, though he’s touched 97 on a handful of occasions this season.
