Mike Yastrzemski’s Homer Clinches Braves’ NL East and Sends the Red Sox to the Playoffs

ATLANTA — Mike Yastrzemski’s three-run homer gave Atlanta a 4–2 victory over the Houston Astros on Sunday and clinched the Braves’ seventh NL East title in nine years.

Yastrzemski, who joined Atlanta in the offseason, hit the decisive home run in the sixth inning with two runners aboard and the game tied. Dylan Dodd then struck out the side in the ninth to secure the win.

Houston’s defeat also eliminated its remaining chance to catch Boston in the American League Wild Card race, clinching the Red Sox’s playoff berth in the same game. Although Yastrzemski has never played for Boston, his home run indirectly sent his former organization into the postseason.

Two celebrations broke out Sunday night with a single swing connecting them. Braves players and staff soaked each other in champagne on the Truist Park field. In Boston, a fanbase that had written off its season in June was alive again, courtesy of a man who shares a Hall of Fame last name but has never thrown out a first pitch at Fenway.

This is what the 2026 baseball season has produced with one week of regular-season games remaining: a dynasty rebooted, a historically improbable comeback confirmed, and a piece of narrative serendipity that no screenwriter would be allowed to keep.

The Braves finished 76-86 last season, fourth in the NL East and out of the playoffs entirely, snapping six consecutive division championships and a streak of seven straight postseason appearances. First-year manager Walt Weiss arrived in the offseason with a rebuilding mandate and, at 92-64, has delivered the third-best record in the National League instead.

“Just felt like they responded well to certain messages,” Weiss said after the field celebration had settled into the clubhouse. “I thought the way they competed was high-level stuff. I felt like the makeup of this team was really good.” Outfielder Mauricio Dubón was already measuring what comes next. “This is first step of what we want to accomplish,” he said. “It’s a lot of hard work — six months of preparation. I think Walt did a great job of bringing everybody together.”

The Braves had already punched their postseason ticket two nights earlier, beating the same Astros 6-2 on Friday behind three separate two-run home runs from Michael Harris II, Ronald Acuña Jr. and Matt Olson. Sunday delivered the NL East title itself, a distinction that changes the bracket and eliminates any need for a wild-card series from Atlanta’s perspective.

The Red Sox story is harder to explain than the Braves’. On June 24, Boston was 32-46 and trailing the AL East race by 15 and a half games. Interim manager Chad Tracy had taken over a roster that looked scheduled for another quiet October. What followed was 52 wins in the next 77 games, which Fox Sports described as one of the most dramatic mid-season turnarounds in American League history. At 85-72, Boston became the first AL team to lose 46 of its first 81 games and reach the postseason, a feat shared only with the 1973 New York Mets.

What connects both storylines is a surname. Carl Yastrzemski spent 23 years in a Red Sox uniform, won the 1967 Triple Crown and American League MVP award, accumulated 3,419 hits and became as close to a franchise saint as that franchise produces. His grandson Mike came up through the Baltimore organization, spent years with the San Francisco Giants and signed with Atlanta this winter. He has never played for the team his grandfather defined.

None of that made Sunday’s swing feel any less purposeful, even if it was accidental in every literal sense. Mike Yastrzemski hit the home run that gave the Braves their title. The same ball, traveling the same arc, gave his grandfather’s franchise their season back.

With six days left before the regular season concludes September 27, CBS Sports has the NL field fully set. The Braves hold the three-seed and open the wild-card series against the Philadelphia Phillies on September 29. The Milwaukee Brewers, leading the NL with the top seed, have a first-round bye. In the American League, the Red Sox are the five-seed and face the New York Yankees, a matchup complicated by Aaron Judge returning to the injured list with a right calf strain that has raised real questions about his October availability.

The Chicago White Sox are still fighting for the third AL wild-card berth against the Cleveland Guardians in the AL Central. Sunday’s results thinned the field but did not close it.

The Braves are in. The Red Sox are in. Whether either team survives October is a question a sixth-inning home run cannot answer. For one night, though, a man from the wrong side of a family dynasty was exactly where both franchises needed him.
