Ben Lindbergh and Meg Rowley talk to Kelly Pracht, the CEO and co-founder of predictive analytics startup nVenue, which has provided the real-time probabilities displayed on this season’s MLB Network-produced Friday Night Baseball broadcasts on Apple TV+. They discuss nVenue’s origin story, its sports-betting ambitions, its 100-plus-input machine-learning model, which factors are and aren’t predictive of performance, Ben and Meg’s misgivings about some of the displayed probabilities, and much more. Then (1:04:37) Ben and Meg bring on FanGraphs writer Ben Clemens to discuss the results of his study about how nVenue’s odds compare to a simplistic, one-factor model, and why they think the accuracy of the system matters.

Last week, I discussed some of the young, pre-free agency players who teams should be trying to sign to long-term contract extensions. I hadn’t been planning for there to be a part two, but you guys had so many additional players you wanted to talk about, and I can’t remember the last time I got more DMs about a piece than that one — well, about a piece for which everyone isn’t mad at me, at least!

So, let’s oil up and turn the crank on the ol’ ZiPS-o-Matic and get this projection mill hopping for seven more players.

Walker Buehler, Los Angeles Dodgers: Eight years, $204 million

Buehler is currently in the second and final year of an extension with the Dodgers that pays him $4 million a year. His next deal will be a tad more pricey. Clayton Kershaw is still around in Dodger blue, but his injury history and mild decline resulted in 2021 being the year that Buehler became The Man in the rotation, reducing Kershaw to the role of deuteragonist. And while Los Angeles still has a rocking rotation, the depth isn’t quite what it was in recent years, so there should be more than slight concern that the franchise’s most valuable pitcher is unsigned. With Buehler two years from free agency, the Dodgers aren’t likely to get any massive discounts, but this is the best time to sign him if you don’t want to pay him Gerrit Cole money later. The Dodgers don’t necessarily have to stop at this figure, either; what’s the fun of being wealthy if you don’t use that cash to pay for cool things?

There may be some concern in some places about the dropoff in Buehler’s strikeout rate, but while strikeout rate changes do tend to stick very quickly, they stick far more when the underlying stats support the drop-off than when they don’t. In this case, the contact rates and swinging-strike rates haven’t worsened at all, nor has his velocity fallen off a cliff, suggesting that it’s a blip rather than a plunge. You can make a similar argument for the Dodgers signing Julio Urías to an extension, likely for a significantly lesser haul, but given the workload Buehler has shown he can handle, he’d be my priority.

Whether or not you’ve seen it, you likely know the premise of Freaky Friday. A mother and her daughter switch bodies in a great cosmic mixup, and hijinks ensue. Hello! Welcome to FanGraphs. I’m Ben Clemens, and today we’ll be covering classic teen cinema of the early 2000s (and mid-1970s), as personified by last night’s Giants-Mets game.

Tuesday night could have been just another day at the (beautiful, well-appointed) office for the Mets and Giants. After a comfortable win by New York in Monday’s series opener, the Giants returned the favor early in last night’s game. Chris Bassitt, the steadiest starter in a rotation buffeted by injuries, had his worst start of the year, surrendering eight earned runs in only 4.1 innings thanks to three homers, two by Joc Pederson. Logan Webb, meanwhile, cruised through five innings (six strikeouts, one walk, two runs), turning what was billed as a pitching duel into an 8-2 rout.

Teams don’t come back from six-run deficits. When Pederson launched his second homer, a two-run shot that pushed the score to 8-2, the Giants’ win expectancy climbed to 98.2%. Tune into 50 games, and you might see the trailing team pull one out. The Mets behaved accordingly; they brought in Stephen Nogosek, the last reliever in their bullpen, to eat some innings.

That’s the way the game could have ended – but let’s get back to Freaky Friday. In 2021, the Giants won these games, whichever side of the 8-2 score they were on. They were both excellent and a team of destiny, and you have to win plenty of tough ones to end the regular season with 107 wins.

The Brewers are atop the NL Central thanks in large part to a rotation that has ranked among the game’s best, but the team’s postseason hopes took a hit this week with the news that righty Freddy Peralta will miss “a significant amount of time” due to a posterior shoulder strain. Milwaukee, which is additionally dealing with multiple injuries in its lineup, believes that Peralta will avoid surgery and return this season, but his loss is a disappointment given the 25-year-old’s recent return to form.

Peralta left Sunday’s start against the Nationals after three-plus innings due to tightness in his left shoulder. He failed to retire any of the three batters he faced in the fourth inning, and all three came around to score, the last two on reliever Brent Suter’s watch along with three others. The five runs that Peralta was charged with were as many as he had allowed over his previous five starts.

Indeed, Peralta had been on a roll. After starting the season by allowing nine runs in seven innings in his first two turns, he went on the aforementioned five-start run. In 28.2 innings, he struck out 38 (a 34.2% rate) and walked six (5.4%) without allowing a single homer, a run capped by his seven-inning, two-hit, 10-strikeout game against the Braves on May 16. Granted, the competition he faced during that strech wasn’t fierce, as the Phillies, Pirates, Reds (twice), and Braves are all below .500, and only Philadelphia has a team wRC+ higher than 94, but such is the schedule of an NL Central contender.

Peralta underwent an MRI on Monday, which revealed the strain. The Brewers expect the injury will heal with rest, but it will take some time. “He will be back this season but it’s going to be a lengthy absence,” manager Craig Counsell told reporters on Monday. “We’re confident that there’s gonna be no aftereffects to this thing but it’s going to take a while to heal and then build it back up.”

Through the ups and downs of his season so far, Peralta’s ERA is a gaudy 4.42, but among the 66 NL pitchers with at least 30 innings through Monday (the cutoff point for all stats here unless otherwise noted), his 2.10 FIP was the league’s lowest, his 0.23 homers per nine ranked third (teammate Adrian Houser was first at 0.21), his 1.3 WAR and 30.3% strikeout rate were sixth, his 22.4% strikeout-walk differential was seventh, and his 2.88 xERA was 14th.

Those peripherals are in line with the All-Star campaign he put up last season. After three years of careful workload management — a span during which he struck out 258 in 192.2 innings but never threw over 85 innings in a season — Peralta broke out with career highs of 27 starts and 144.1 innings in 2021. Among NL pitchers with at least 140 innings, his 2.81 ERA placed sixth and his 3.12 FIP was seventh. His 33.6% strikeout rate was third behind only teammate Corbin Burnes and Max Scherzer, and his 24.0% strikeout-walk differential was good for fourth behind that pair and Aaron Nola. Only a late-season bout of shoulder inflammation, for which Peralta spent 15 days on the injured list and had a few shortened starts on either side, put a damper on his strong campaign and prevented him from down-ballot consideration in the Cy Young voting.

“When you’re pitched away, take the ball to the opposite field.” It’s a training mantra that seemingly exists everywhere. I heard it in Little League. I hear it on major league broadcasts to this day. The data show that hitters do it, and it’s just a natural swing. I can think of few hitting sayings I believe more than this one.

Of course, just because you can hit the ball the other way doesn’t mean you have to. Over the last two years, the list of righty hitters who have pulled the ball most when they swing at away pitches (from right-handed pitchers, just to standardize the sample) probably matches your intuition:

You basically understand the kinds of hitters on here. The guys ranked sixth and seventh are similar types: Salvador Perez and Mike Zunino. It’s big boppers who try to lift and pull the ball no matter where they’re pitched, as well as guys like Marcus Semien who sell out to pull in an attempt to juice their power. If you do the most damage on the pull side and accrue most of your offensive value through power, it’s a natural approach. You think anyone’s coming to the ballpark to see Patrick Wisdom slap a well-placed cutter the other way? They want dingers!

The list of the hitters who pull the ball least often when pitched away is mostly who you’d expect, and also not who you’d expect at all. Feast your eyes on the top five:

The top four are contact-oriented hitters with elevated groundball rates… and the fifth might be the most powerful baseball player in history. Read the rest of this entry »

The Cardinals are only second in the NL Central right now, but they’ve been having some fun lately. On back-to-back Sundays, they sent elder statesmen (and likely future Hall of Famers) to the mound to close out lopsided games — first Albert Pujols against the Giants and then Yadier Molina against the Pirates. What’s more, the Cardinals were on top in both of those games by double-digit scores, placing the pair in a rare subset within the annals of position players pitching.

That’s not the only interesting recent development when it comes to those accidental moundsmen. But as it’s been awhile since I last delved into the topic, it’s a good place to start.

So let’s set the wayback machine to May 15, the night that the Cardinals faced the Giants in St. Louis for ESPN’s Sunday Night Baseball broadcast. With lefty Carlos Rodón on the mound for San Francisco, the 42-year-old Pujols, who returned to the nest this spring after a decade-long run with the Angels and, briefly, the Dodgers, was in the lineup. Though righties are still a problem, he’s ably served as a platoon designated hitter against southpaws; to date he’s hit .227/.329/.439 (125 wRC+). On this night, Pujols and company went to town on Rodón, scoring nine runs over the first four frames, with eight of them charged to the starter, and the veteran slugger collecting a double and an RBI single within that onslaught. The Cardinals kept scoring, adding two runs apiece in the fifth, sixth, and seventh; by the end of the eighth, they led 15–2. Read the rest of this entry »

Last week, I talked about a few young players who teams should be itching to sign to long-term contracts. Due to public demand, another set of projections is on the way, but I’ll admit I intentionally omitted one pitcher, Pablo López, from the first look because I wanted more space to talk about him.

Unlike a lot of pitchers the Marlins have accumulated during their various fire sales, López wasn’t a highly touted arm in the minors. Prior to 2017 — the season during which he and three other players were traded by the Mariners to the Marlins for reliever David Phelps — he was basically a non-entity among prospect-watchers. He didn’t receive an official ZiPS projection that year, but if he had, it would have been similar to the projection he received before the 2018 season, which essentially saw him as a below-average innings-eater at his peak. At no time did he rank on a ZiPS Top 100 prospect list.

His first couple of campaigns with the Marlins featured decidedly mixed results. While López was essentially a league-average pitcher thanks to exit velocities that ranked towards the top of the league (the good kind of top of the league), he lacked the ability to finish off batters. From 2018-19, he basically threw four pitches: a relatively straight fastball, a sinker, a curve, and a changeup. None them were whiff-makers, and none of them had even a 20% put-away rate, resulting in a mediocre 7.5 K/9 combined over those two seasons. Read the rest of this entry »

This season, Eric and Tess Taruskin will each have a minor league roundup post that runs during the week, with the earlier post recapping some of the weekend’s action. You can read previous installments of our prospect notes here.

Alec Burleson, RF, St. Louis Cardinals
Level & Affiliate: Triple-A Memphis Age: 23 Org Rank: TBD FV: 40+
Weekend Line: 9-for-13, 3 2B, HR

Notes
As the Cardinals are apt to do with their prospects, they pushed Burleson, a former two-way player, to the upper levels very quickly, having him spend most of his first full season at Double-A before a late-season promotion to Memphis, where he began 2022. He has had virtually no issues, slashing .282/.337/.486 so far as a pro, with a whopping .321/.367/.591 line at Triple-A this year. Burleson has above-average raw power and is hitting the ball hard despite utilizing a simple swing, one that becomes even simpler when he has two strikes. He is adept at hitting up-and-in fastballs, though he sometimes strangely inside-outs them to left field, and he also tends to take pitches down and away from him the opposite way, with enough strength to do extra-base damage in that direction.

Burleson is a pretty aggressive hitter whose chase rates have historically been in the 37-40% range, which would put him among the top 25 or so swing-happiest qualified big league hitters. It’s a somewhat scary underlying data point for a guy who doesn’t bring a lot to the table on defense, as Burleson is a tentative corner outfielder with a surprisingly average arm for a former college pitcher. Burleson has absolutely put himself in the short-term big league conversation with his upper-level performance, but there’s still bust risk here and he’s likely a corner platoon bat who’ll compete with Lars Nootbaar (who has better plate discipline, but a swing less optimized for power) for plate appearances against righties once Corey Dickerson’s one-year deal is up.
