Guardians Clinch a Playoff Berth With the Central Open

The Cleveland Guardians clinched a playoff spot for a third straight year, beating the Boston Red Sox 1-0 on Thursday at Fenway Park. Angel Martínez’s homer in the second inning was the only run, and closer Cade Smith struck out the side for his major league-leading 41st save.

Cleveland is 83-76 and still one game ahead of the Chicago White Sox. The berth is locked. The AL Central, and the open week that comes with it, is not.

A 319-Foot Homer Inside Pesky’s Pole

Martínez’s 18th home run of the season left the bat at 93.8 mph and traveled a 319-foot homer to right field, tucking inside Pesky’s Pole. It broke up a four-up, four-down start by Ranger Suárez and was the only ball Cleveland hit that mattered.

The Guardians managed four hits. They went 0-for-5 with runners in scoring position. José Ramírez singled twice and stole a base. Chase DeLauter, who entered the night hitting.287, went 0-for-4 with three strikeouts. Steven Kwan walked once and did not get a hit. Jo Adell, the deadline outfielder hitting in the middle of the order, also went quietly.

Boston had two hits and was shut out for the eighth time this season. Suárez (8-5) lasted five innings, allowed that one run, struck out five, and retired his last eight hitters. Ceddanne Rafaela was back in center a night after leaving with right hamstring tightness. Smith fanned him for the last out.

That was enough for Cleveland’s third consecutive postseason berth, the 19th in franchise history, and a celebration in a visiting clubhouse at Fenway.

How the Bullpen Turned One Run Into a Clinch

Daniel Espino started and threw one inning. The night then became a bulk-relief win, the kind this staff has been living on since Joey Cantillo came out of the rotation.

THE ARMS THAT FINISHED FENWAY

• Joey Cantillo: Five innings, one hit, two walks, four strikeouts, and the win that moved him to 11-9.
• Hunter Gaddis: Worked the seventh, turned a leadoff walk into a 6-4-3 double play, then allowed a Jarren Duran single.
• Erik Sabrowski: Struck out two in a clean eighth.
• Cade Smith: Struck out the side in a 1-2-3 ninth for save No. 41.

Cantillo has now thrown 15 straight scoreless innings across his last three outings in that bulk role. Cleveland’s pitchers struck out 12. They are the only staff in the majors with four starters who have made at least 30 starts, and the club still ranks eighth in ERA (3.73) and second in strikeouts (1,510) even as the lineup sits 27th in runs and 29th in OPS.

Chicago Still Owns the Tiebreaker After 13 Games

The White Sox also clinched a playoff spot on Thursday, beating Kansas City 9-1, and they still sit a game back at 82-77. They won the season series. Cleveland is 6-7 against the White Sox in 13 games, and Chicago took those meetings 58-57 in runs. If the records finish even, Chicago is the Central champion. Ties are now settled by math, not by a Game 163.

THE AL CENTRAL WITH THREE GAMES LEFT

Cleveland’s run differential is +3 (653 runs scored, 650 allowed). Chicago’s is +52 (760-708). The Guardians have been the tighter pitching team. The White Sox have been the better offensive club, and they already hold the one result that would decide a dead heat.

The Bye Goes Only to a Division Winner

A wild-card berth puts Cleveland in a best-of-three that starts on Sept. 29. A Central title is the piece that actually changes the October calendar. Only division winners can be seeded in the top three, so the Yankees (92-67) and Red Sox (85-74) cannot rise above No. 4 and No. 5 even though both have better records than anyone in the Central.

The way the bracket sits, the Central winner is highly likely to take the No. 2 AL seed and a bye into the Division Series, with the Division Series opening on Oct. 3. That extra rest would let manager Stephen Vogt line up Gavin Williams and Parker Messick at the front of a five-game set. Lose the Central, and Cleveland is a wild card, with Boston still two games ahead for the No. 5 seed and already holding the tiebreaker over Chicago.

The Guardians do own the tiebreaker over the Red Sox after Thursday, a detail that would matter only if they slip behind Chicago and start trading wild-card slots. The clean path is still the one in front of them: finish with a better record than the White Sox, take the division, and skip the first round.

Cleveland Sat Five Games Under.500 in August

This was not the 2025-style historic sprint, but it was another late repair job. Prognosticators doubted a quiet offseason. Then the injuries hit, the bats went quiet, and the White Sox opened a gap that looked like it would hold.

THE ROAD BACK FROM 61-66

1. June 6, 2026: Ramírez, DeLauter and Martínez each go down with injuries that cost them multiple weeks, and the club treads water without its core.
2. July 13-16, 2026: The Guardians enter the All-Star break at 51-46, still tied with the White Sox for first.
3. Aug. 3, 2026: Cleveland adds Jo Adell, Nathaniel Lowe and pitcher Foster Griffin before the trade deadline to lengthen a lineup that had ranked near the bottom of the league.
4. Aug. 19, 2026: A 1-0 loss to the San Francisco Giants drops them to 61-66 after a 10-20 slide, 5 1/2 games back.
5. Aug. 20-Sept. 24, 2026: They go 22-10, take sole possession of first on Sept. 18, and clinch the berth on Thursday in Boston.

Cleveland entered Thursday tied with Milwaukee for the best record in the majors since Aug. 20. Since Aug. 4 it had scored 4.58 runs per game, third in the AL, after ranking 14th at 3.95 before the deadline. Ramírez is still working through the after-effects of surgery. Kwan, who was having a career-worst first half, has been better since. Martínez now leads the club with 18 homers. Brayan Rocchio leads it with 70 RBIs. Messick, with a 2.55 ERA, is in the Cy Young and Rookie of the Year mix beside Williams.

Adell Finally Reaches October

Adell arrived from the Angels on Aug. 3 in a deal for Double-A catcher Jacob Cozart and is in the postseason for the first time in a seven-year career. “We knew we were one away from making it happen,” he said. “It was business as usual. Everybody go out and play your game.”

Vogt has now taken this club to October in each of his three seasons as manager. Last year’s team went 20-8 in September. This one is 14-8 this month with three games left.

It’s three years in a row that our fans get to watch playoff baseball. This is why we play. We play for our fans. We play to give them an October to remember. We’re really proud that we get to do it again.

Stephen Vogt, Guardians manager, after the win at Fenway Park

He also pointed at the new faces. “What I love is that we have a number of guys who have never been in this position, playing meaningful games in September or playoff baseball,” Vogt said. “It’s just so fun to watch Jo Adell celebrate.”

Chicago’s climb sits next to that party whether Cleveland likes it or not. The White Sox lost 101 games in 2023, a Modern Era-record 121 in 2024, and 102 in 2025. FanGraphs had them at a 1.2% playoff chance on Opening Day, with a 0.6% shot at the division and a 0.1% shot at a bye. They still held a share of first for 96 days, including a 73-day run from July 5 until Cleveland took a series rubber match in mid-September, and they led this division by 5 1/2 games in mid-August.

Three Results Will Settle the Central

Cleveland’s magic number is three. Any mix of Guardians wins and White Sox losses that adds to three wraps the division, because a 3-0 finish for both clubs would leave Cleveland at 86-76 and Chicago at 85-77. A 0-3 weekend for both would still leave Cleveland a game up. Chicago has to win one more remaining game than Cleveland just to force the tie it already owns.

The last three are not equal. Cleveland goes to last-place Kansas City on Friday, Saturday and Sunday. Chicago hosts Colorado. Williams (14-8, 3.63 ERA) is listed for the 7:40 p.m. ET opener on Sept. 25. If the Guardians win the Central, they would likely meet the White Sox, Houston or Texas in the AL Division Series, with an extra week to reset a staff that just clinched on an opener, a bulk left-hander and a closer.

Vogt did not treat the champagne as the finish. “This doesn’t get old and you can’t take one minute for granted,” he said. “It’s not a given that you’re going to get in. To punch your ticket and know you have an opportunity to win a World Series, you can’t beat it.” The ticket is punched. The bye is still sitting in Kansas City.
