For four games, pitching chaos helped the South Siders reign. Armed with only one starter in his circle of trust, White Sox manager Will Venable leaned on his band of mostly young, mostly hard-throwing relievers. Who, and for how long, was dictated by circumstance. It worked early, as Chicago swept through Houston in the Wild Card Series and jumped out to a 2-0 lead in the ALDS against the Guardians. Venable pressed all the right buttons — the staff allowed just nine runs across those first four games — and deserves a ton of credit for getting a dozen pitchers to embrace such a novel strategy on the fly.

All along, we’ve been waiting for the other shoe to drop. How long can the White Sox get away with throwing Grant Taylor multiple frames every outing? Will Hagen Smith finally pay for walking a batter per inning? What happens if Chicago needs an actual starter to eat a couple of innings?

The first cracks in the dam appeared Wednesday, when Chicago walked 10 and the Guardians exploded for nine runs. Water trickled through in the early innings of Thursday’s Game 4, too, and then burst through all at once as Cleveland, again facing elimination, defeated the White Sox, 9-5, to force a do-or-die Game 5 on Saturday.

I just finished an extended trip to watch instructs and the Arizona Fall League, and I’ve got enough in the notebook for a few posts. We’ll start with some of the looks I got at Royals, Giants, and Padres prospects on the backfields and, in a few cases, during the AFL as well. Let’s hop to it.

Kansas City Royals

Angeibel Gomez, OF

We’ll start with the guy people will ask about first. Gomez is a tapered 6-foot-2. While he isn’t a freaky athlete in the Elly De La Cruz mold, he’s limber and has a fast bat for a kid his age. Facing some of the best stuff of his life, his feel for hitting stood out. Gomez is athletic in the box, and he was able to fight off above-average velo on the hands, turn around 97 above the belt, and flatten the bat and hit a line drive on a hard fastball up, all while holding his own versus spin. He fouled off a couple tough sliders and took one just beneath the zone. He wasn’t perfect — he expanded the zone a few times and chased a curve in the dirt — but it was a really impressive showing in context.

Where does this go from here? To my eye, Gomez doesn’t look like an early-mature guy, but he also isn’t someone who screams “physical projection” in the way that, say, Sebastian Walcott did at his age. Gomez already has average measurable power, and while there’s room for him to grow into more, my projection leans closer to “comfortably plus” than “80.” Read the rest of this entry »

At no point during the National League Division Series between the Brewers and the Padres did either team lead by more than two runs. The total runs scored in a game never exceeded seven. But neither fact should in any way imply that the series was a no-offense snoozefest.

All four games produced a disproportionate number of baserunners given the actual number of runs allowed, at least when compared to regular-season averages. During the 2026 season, the league averaged nine runs per game on around 24 total baserunners. The Brewers and Padres likewise averaged 24 baserunners per game, despite logging combined run totals between four and seven. Close games and that much traffic on the basepaths made this series a real booty-hole-clenching experience for fans of both teams, as well as the empathetic neutral observers. By the time the fans watching Game 4 could finally unclench, the Brewers had defeated the Padres, 3-1, to advance to the NLCS against the Dodgers.

Though both teams named a traditional starter for Wednesday’s Game 4, neither Walker Buehler for the Padres nor Robert Gasser for the Brewers was expected to pitch particularly deep in this game. Buehler was healthy enough to make 32 starts this season for the first time since 2021, but he wasn’t able to match his innings total (207 2/3 IP) or replicate the 60 ERA- he posted that year. Instead, he was a slightly below-average starter, with an ERA- of 115 over 153 2/3 innings. He also missed the first two games of the NLDS on paternity leave, which likely interrupted his typical throwing schedule, and any departure from routine has the potential to leave a pitcher feeling out of rhythm. Buehler wound up going three innings, allowing one run on a pair of consecutive singles from Sal Frelick and Garrett Mitchell. His command looked shaky from the jump and alternated between non-competitive pitches outside the zone and offerings that caught way too much of the plate.

For his part, Gasser covered four innings, and the only real blemish on his evening was a solo shot hit by Fernando Tatis Jr. to lead off the third. After spending the first half of 2026 on the Triple-A shuttle, Gasser was able to stick in the majors from July 11 onward, posting a 93 ERA- over 109 1/3 innings. A lefty with a low arm slot, he gave the Brewers the option to throw a slightly different look at the Padres than what they’d seen during the first three games of the series. He relied heavily on his sinker, using it to set up his changeup and sweeper. Because of how the pitches interacted with one another, he locked up hitters for 10 called strikes on his sinker, while getting hitters to chase his changeup and generate weak contact on his sweeper.

But with the starters out relatively early and the score knotted at one through four innings, the game would ultimately be decided by the pitchers entering from the bullpen. Both teams had used almost their entire pitching staff extensively over the first three games, making the hitters more familiar with their opponents on the mound than new dads Buehler and Mason Miller are with their newborn children. (Miller missed Game 3 for the birth of his first child.) Read the rest of this entry »

Stephanie, you can send it in.

Come on in. Thanks for coming all the way up on short notice, and, uh, sorry about the mess. I really should’ve saved Mr. Splash for later in the day. I’d never seen him fire that water gun in anger before, but he is remarkably accurate. Did you know he was a Green Beret? Anyway, have a seat. I have some difficult news for you.

Oh jeez, I didn’t think about the tail feathers. You can stand, whatever. You can stand.

So as you know, we have been forced to make some pretty substantial cuts. And believe me, it’s the last thing we want to do. We consider everyone who works here family. But there comes a time within any family when you have to identify your least productive family members, cut them out of your life forever, and leave them without any way to support themselves, at which point they’re not family anymore. They’re just strangers who know things about you that you’d rather not become public. Unfortunately, that includes you. Are – are you following any of this?

We’re going to have to let you go.

I realize that you’ve been with us for – wow – coming up on 50 years now, and I want to assure you that we are grateful for everything you have given to the Baltimore Orioles organization. You’ve brought happiness and joy to so many people. Unfortunately, it has been determined that keeping you on staff would be a suboptimal allocation of resources, because according to a report from this latest round of consultants – you know, I think you deserve to know the truth, so let me get my glasses so I can quote this accurately – “Happiness and joy don’t make the cash register go ka-ching.” So really, our hands are tied.

You want your ace on the mound when all the marbles are in the fire. When the stakes are high, the big cheese needs to have his hands on the wheel. Are those real metaphors? No, but I bet you knew what I was talking about in each case, because the playoffs are a perfect time to discuss the importance of star pitchers. But do you want to deploy them as early in the series as possible? Or do you want them for the decisive game? Does it even matter?

In our game chats and article comments — across the internet really — it’s hard to find a consensus. When I wrote about Chris Sale earlier this week, there were comments to the effect of “It’s a bummer he pitched out of the ‘pen in the Wild Card, now he won’t get to pitch in NLDS Game 5,” as well as “Don’t save Sale for Game 7 of the NLCS, there might not be a Game 7!” Those are exact opposite opinions, and yet they both make a lot of sense when I hear them. But they can’t both be right, so let’s do some math. Even though there’s no real adage to prove or disprove here, this feels like a job for Mathemadage.

Here’s the question, as I see it: For a given set of pitchers making postseason starts, which way would you like those starts arranged in a seven-game series? In other words, if you have an ace, a second banana, and some bullpen games, would you prefer to have your ace for Games 1 and 5 or Games 3 and 7? There are good intuitive reasons to prefer either. Games 1 and 5 happen in almost every seven-game series; Game 7 is a much less frequent occurrence. More innings for my best guy, please! But the stakes can also never be higher than they are in a decisive game. In a big spot? Why wouldn’t I want my best guy in? Read the rest of this entry »

NEW YORK — For one brief moment, all had been forgiven. The unreasonable hope, the unbearable burden, the unfulfilled potential — it all had led to this point, when the local kid and lifelong Yankee fan finally made good.

Anthony Volpe stepped into the box in the bottom of the sixth inning with a runner on first, two out, and the Yankees down by two and facing elimination in Game 3 of the American League Division Series. After taking a Griffin Jax sweeper in the dirt for a ball, the one-time second coming of Derek Jeter, who’d stalled and backtracked and flamed out in frustrating fashion, turned on a sinker running in on his hands and lifted a high-arching fly ball to left field that just cleared the wall for a game-tying home run. As he made his way around the bases, all the emotions of the last four years came pouring out of him.

But just after he crossed the plate, the six umpires came together and called for a crew chief review. Reality set in as the replay repeated on the jumbotron in center field, showing different angles of the same disappointing event. Several minutes of deliberation made it official: The home run was overturned. A fan in the first row had reached over the wall with both hands and touched the ball before it rolled up his arms and into his lap.

Volpe was awarded second base, as the umpires determined that the ball would not have been caught even if the fan hadn’t interfered with it. They also concluded that George Lombard Jr., who began the play on first and was running on contact with two outs, would’ve scored on the play. That run turned out to be the final one of the game for either team, as the Rays held on to beat the Yankees, 4-3, and complete the sweep. Read the rest of this entry »

After cruising through the NLDS with a gentleman’s sweep, the defending-champion Los Angeles Dodgers are headed to the National League Championship Series for the third year in a row. A day after Yoshinobu Yamamoto silenced Atlanta’s bats in Game 3, the Braves and Dodgers ran out the finest Tylers they had to offer, and both pitchers excelled. The difference largely came down to the bullpens. With a bevy of rested options to choose from, Dave Roberts went and got his pitchers at the first sign of trouble. In contrast, Walt Weiss, who ran a bullpen game in Game 2 and needed four innings from his ‘pen in Game 3, stretched his pitchers a bit further than they could manage, and although it took seven innings, he finally paid for it. The Dodgers took the game 4-1 and the series 3-1. They now await the winner of the Brewers/Padres series in the NLCS, but you have to imagine they’re not too worried either way.

If you were the Braves, you might have circled Tyler Glasnow’s start on the postseason calendar. This Dodgers rotation has about as many soft spots as the four horseman of the apocalypse, but Glasnow missed much of the season with back spasms, hadn’t pitched in 13 games, and had underperformed his peripherals in a major way. Since he returned from the IL, Glasow had run an excellent 2.14 FIP because he was striking out nearly 13 batters per nine, but his ERA was an unsightly 4.46. When your other options are Yamamoto, Tarik Skubal, and Blake Snell, you’ll take it.

The Braves manufactured the first run of the game. More specifically, leadoff man Michael Harris II manufactured it almost single-handedly. Glasnow started Harris with a 96-mph fastball right at the top of the zone, and Harris was all over it, shooting a low liner through the right side of the infield at 107 mph. With basestealing guru Antoan Richardson in the first base coaching box, Harris got out to a huge vault lead and easily stole second base two pitches later. He could have had third as well, but he didn’t see Will Smith’s throw continue into center field. Harris made it there eventually, advancing on a Matt Olson groundout. Three pitches later, Glasnow spiked a 1-1 curveball to Ozzie Albies, and Harris didn’t hesitate for a second. He broke as soon as he read the pitch’s downward angle. It bounced well in front of the plate, and Smith did well to block the high bounce, but he couldn’t keep it close. Harris scored easily. With their season on the line, the Braves had a 1-0 lead.
