The first weekend of the 2026 MLB season is over, and we’ve learned so much in this new era of the sport.

The ABS system has been a smashing success for everyone but the umpires, and the two teams that delivered arguably the greatest World Series of all time are, shockingly, still really good.

Along with the Los Angeles Dodgers and the Toronto Blue Jays, three other teams made it through their opening series without a loss.

Here are the teams still undefeated heading into the first full week of MLB baseball of the year.

Los Angeles Dodgers

The Dodgers had a Hollywood entrance as they returned for their three-peat quest in Los Angeles, beating the Arizona Diamondbacks in all three of their opening games.

While the Dodgers won, though, Arizona started each game with a 2-0 lead. It was the heroics of Will Smith and Mookie Betts that kept their perfect record intact, along with a pair of Edwin Díaz closes.

Toronto Blue Jays

While the Blue Jays reached the World Series with an iconic offense, it was their pitching and defense that got them started on their 2026 winning streak.

The Athletics put up a good fight north of the border, but it was the debut of Dylan Cease along with some timely hitting that won out the weekend. Kazuma Okamoto is also a quick fan favorite in Toronto, hitting his first career MLB home run on Sunday.

The Yankees embarrassed the San Francisco Giants on the road to begin the 2026 MLB season.

They started their campaign on Wednesday with the Netflix “Opening Day” broadcast, and while characters from the streamer were artificially placed in the audience, the Yankees put on a show.

The most impressive thing about the Yankees’ start? They only allowed the Giants to score one whole run during the three-game sweep.

Milwaukee Brewers

The Brewers mashed against the Chicago White Sox at home to begin their 2026 campaign.

The best team in baseball last year during the regular season wants to get back to the playoffs and exact revenge on the Dodgers, and they’ll need a top-tier offense like they showed opening weekend to do it.

If Christian Yelich can keep up his form like he did against the White Sox for the rest of the season, he might turn back the clock and be a dark-horse National League MVP candidate.

Miami Marlins

Sure, it was against the Colorado Rockies, but the Marlins might actually be good this season.

The fans in South Beach were celebrating following an Owen Caissie homer to complete the sweep, and there is actual optimism for a team that has been stagnant for over a decade.

And who comes to town next? The White Sox.

There’s a legitimate chance that the Marlins are the last perfect team left standing.
