Guardians, White Sox Set for First MLB Division Series Showdown

The 2026 MLB division series matchups are starting to take shape with the Chicago White Sox becoming the first team to advance out of the wild-card round .

Chicago's sweep sets up a division series with the Guardians , starting Saturday in Cleveland.

What have we learned about each team so far? What does each remaining team need to do to move on to the American League Championship Series? Which players could be their teams' October difference-makers? And which favorites should be on upset watch in the round ahead?

Our ESPN MLB experts are here to break it all down as every division series matchup is set.

Upset forecast: The Guardians win 57% of simulations. Though Chicago led the AL Central for the bulk of the season, Cleveland once again looked like the class of the mediocre division by season's end. The White Sox owned a better regular-season run differential, but the Guardians entered the postseason on one of their signature September heaters.

Both teams rely on an inordinate amount of production from rookies. As good as the White Sox's first-year players have been, no club can match what the Guardians have gotten from Parker Messick , Chase DeLauter , Travis Bazzana and others. Cleveland was the hotter team at the end of the season, and this is another series where home advantage might matter. That's not because the Guardians were that good at home but because the White Sox struggled so much on the road, ranking 20th in wins and run differential away from Rate Field.

Guardians concern level: Sky high. For a team with so many young players, the Guardians are dragging a lot of historical baggage. Some of that is historical (no titles since 1948) but more of it recent. Cleveland keeps getting into the playoffs but with each run that falls short of the World Series, the pressure mounts. Meanwhile, no team left in the playoffs is playing with as much house money as the White Sox. -- Bradford Doolittle

What impressed you most about the White Sox in the wild-card round?

The same thing that impressed me about them all season: Their bullpen. It was masterful in their Game 1 win and did enough after that to secure the series win. It's about as close as you'll come to a staff with every pitcher trained to pitch multiple innings every time out. Manager Will Venable has taken advantage of that all year and it continued in the wild-card round.

From the first pitch of the wild-card games to the last out of the World Series, we've got you covered.

Why will/won't it continue against the Guardians?

With some time to rest before the ALDS starts Saturday and then three days off within the series there is no reason the White Sox can't continue to lean on that pen. I may not have the same feelings if they advance to the ALCS -- at some point they'll run out of gas - but the familiarity with the Guardians will also work to their advantage. The bullpen carrying them for one more round is a real possibility for Chicago.

Which one player must deliver for Chicago to keep its run going?

It's a tough call with so many options to choose from, but Hagen Smith has been lights out since coming up and he is less of a known commodity than others on the staff. And with those days off in the division series, Smith could impact up to three games.

The easier answer to the question would be Miguel Vargas or even fellow reliever Grant Taylor but after throwing three scoreless innings in Game 1 of the wild-card round, Smith is my x-factor for the next one. -- Jesse Rogers

What carried the Guardians to an October bye?

They went 9-1 down the stretch to clinch the AL Central after trailing by as many as six games in the middle of August. From Aug. 18 to the clinching game, the Guardians went 25-11 with a 3.51 ERA. That will have to be the formula in the playoffs: Pitching, pitching and more of it.

Rookie Parker Messick, who finished with a 2.56 ERA, and Gavin Williams , who led the AL with 248 strikeouts, led the way, while closer Cade Smith led all relievers in win probability added while saving 41 games and fanning 107 in 74 innings.

The offense was much better in the second half, with Steven Kwan hitting .352 with a .445 OBP the final three months, but the pitching will be the key.

Why will it/won't it continue against the White Sox?

The Guardians will be the heavy favorite since they're rested with their rotation lined up while the White Sox lack the pitching depth of Cleveland's staff. Yes, the White Sox have more power -- Angel Martinez led the Guardians with 18 home runs -- but the Guardians did have their best power month in September, slugging .430 with 35 home runs in 25 games. Travis Bazzana, Brayan Rocchio , Chase DeLauter and Martinez all had good final months, so suddenly the Cleveland lineup looks playoff-worthy.

Which one player must deliver to put them in the ALCS?

It still feels like Jose Ramirez needs to offer some big contributions at some point, something he hasn't done much of in the postseason in his Hall of Fame career. He's hit .234 with just four home runs in 45 career playoff games. If we focus on more recent years, he's hit .246 with two home runs in 19 games since 2022.

He's hit for very little power since returning from a fractured left hamate bone, hitting just two home runs in 53 games after coming off the IL, but Stephen Vogt has still been hitting him second in the lineup down the stretch. That's a run-producing spot in the order and he'll need to produce some runs. -- David Schoenfield
