With Rivalry Weekend returning on May 15-17, 2026, we rank the 10 fiercest feuds in baseball, from the Bronx to the Bay.

Baseball's 162-game season is a marathon - and the upcoming Rivalry Weekend is the bit where everyone sprints.

For three days in May, MLB throws out the blandness of regular-season scheduling and lines up the grudge matches fans actually care about.

Subway Series. Freeway Series. Crosstown Classic: all compressed into one weekend where bragging rights matter more than the standings.

Rivalry Weekend 2026 runs Friday 15 May through Sunday 17 May, and it's only the second edition ever.

MLB started running it in 2025, so the format is new even if most of the feuds themselves go back a century.

The 2026 slate includes Yankees at Mets, Dodgers at Angels, Cubs at White Sox, Rangers at Astros, Royals at Cardinals, and Orioles at Nationals.

Not every pairing is a classic, because some teams don't have a natural rival and get paired on geography alone. But the marquee series carry genuine weight, and for one weekend MLB feels less like a slow burn and more like a proper event.

To better understand this extremely special event, we rank the 10 biggest rivalries in baseball, cover how the weekend works, and lay out how Aussie fans can catch the action on Kayo and Foxtel.

The 10 Biggest MLB Rivalries, Ranked

Bragging rights aren't distributed evenly in MLB: some of these feuds have 130 years of baseball behind them, others are recent inventions built on postseason grudges and shared area codes.

Either way, when these teams meet the temperature goes up. Here's the ranked rundown.

10. Mariners vs. Padres (Vedder Cup)

The most recent rivalry on the list, and also the most unusual origin story. The Mariners and Padres aren't division rivals, aren't geographic neighbours, and don't share postseason history. What they share is Eddie Vedder.

The Pearl Jam frontman lived in San Diego before relocating to Seattle in the early 90s, so fans turned that into a gag rivalry for years.

In 2025 MLB made it official: the winner of the annual series now takes home the Vedder Cup, a 1963 Fender Telecaster that Vedder himself designed.

It's a manufactured rivalry, sure, but both teams have trended upward recently so the on-field product backs it up. Julio Rodriguez against the Padres' young core is a genuinely compelling watch.

9. Royals vs. Cardinals (I-70 Series)

Kansas City and St Louis sit at opposite ends of Interstate 70 in Missouri, which gives the rivalry its name.

The I-70 Series predates interleague play, because the two teams met in the 1985 World Series, which the Royals won in seven games for their first championship.

They've played every year since 1997, so there's genuine continuity. Kansas City reclaimed control in 2024, taking the head-to-head series for the first time since 2016.

It won't match Yankees-Red Sox for venom, but for baseball fans in middle America it's the one they circle on the calendar.

The 2026 Rivalry Weekend matchup sees the Royals travel to Busch Stadium, traditionally where the rivalry has its most hostile atmosphere.

8. Dodgers vs. Angels (Freeway Series)

Southern California baseball. The Dodgers play at Dodger Stadium in central LA, the Angels play in Anaheim about 50km south. You can drive between the two stadiums on the I-5, hence the Freeway Series name.

The Dodgers have been the dominant franchise for years, winning three World Series since 2020.

The Angels have been irrelevant for most of that stretch despite having Shohei Ohtani and Mike Trout on the roster. Ohtani has since defected across town to join the Dodgers, which added a fresh layer of spite to the rivalry.

The Freeway Series is defined by star power more than tight competition, but for LA sports fans it's the biggest baseball grudge of the year. Rivalry Weekend 2026 has the Dodgers visiting Angel Stadium.

7. Cubs vs. White Sox (Crosstown Classic)

Chicago has two MLB teams and they genuinely don't like each other.

The Cubs play at Wrigley Field on the North Side, the White Sox play on the South Side, and the divide between the two fanbases is about as stark as it gets in American sport.

The Crosstown Classic is relatively new in regular-season terms, since the two teams only started playing annually after interleague play was introduced in 1997. Before that, their only real meeting had been the 1906 World Series, which the White Sox won 4-2.

The Cubs have dominated recently, going 12-2 in Crosstown games since 2023 including a 4-0 sweep of the 2024 season series. White Sox fans still treat the rivalry with full intensity, because in Chicago losing to the other side is unforgivable.

6. Astros vs. Rangers (Silver Boot Series)

Texas baseball, and this one has real postseason juice. The Astros and Rangers have been AL West rivals since Houston moved over from the NL in 2013, so they play each other plenty during the regular season.

But it's the 2023 ALCS that cemented this as one of the league's most heated rivalries.

Texas beat Houston in seven games on the way to winning their first-ever World Series title. It was a brutal series with bad blood on both ends.

The Astros have historically owned the season series, winning every year since 2016, though the all-time head-to-head is nearly even at 146-146.

The trophy is literal, a plated cowboy boot called the Silver Boot. Crowds at Globe Life Field and Daikin Park bring a different energy than a standard AL West game.

5. Mets vs. Yankees (Subway Series)

The Subway Series carries a different kind of weight than your typical divisional rivalry, because the two teams meet in the same city but play in different leagues.

These aren't games for the standings. They're games for New York.

The rivalry peaked with the 2000 World Series, which the Yankees won in five. Since then it's simmered, flared up, and simmered again depending on who has the better roster.

2025 added a new chapter when Juan Soto left the Yankees for a 765 million dollar deal with the Mets, so every Subway Series now carries personal stakes on top of the civic ones.

Yankee Stadium and Citi Field are separated by about 15km. The fans, by considerably more. Rivalry Weekend 2026 has the Yankees travelling to Citi Field.

4. Cubs vs. Cardinals

The oldest NL Central rivalry, and one of the purest in baseball.

Both franchises trace their history back to the 19th century, both have passionate fanbases in classic Midwestern baseball towns, and they've been playing each other regularly for over a century.

The Cardinals have had the better franchise by most measures, with 11 World Series titles to the Cubs' three.

The 2016 Cubs title snapped a 108-year drought and temporarily flipped the dynamic, since the Cubs fanbase finally had something to hold over the Cardinals after decades of being the lovable losers.

The teams play each other 13 times a year as division rivals, so there's no shortage of data on who holds the edge at any given moment. It's the rivalry locals rate highest on pure baseball terms.

3. Dodgers vs. Yankees

More World Series meetings than any matchup in baseball history. Twelve, to be exact, with the Yankees leading 8-4 overall.

The most recent chapter came in 2024, when the Dodgers won in five games to snap a 43-year gap between Fall Classic meetings.

The rivalry started as an intracity feud, back when the Dodgers were still in Brooklyn. The Yankees won five of their first seven World Series meetings between 1941 and 1956.

After the Dodgers moved west in 1958, the rivalry became coast-to-coast, with the 1963, 1977, 1978 and 1981 World Series all pitting them against each other.

Regular-season meetings have historically been rare as they play in different leagues on different coasts.

The balanced schedule now guarantees at least one series a year, and the Ohtani-Aaron Judge era makes every meeting must-watch.

2. Dodgers vs. Giants

Baseball's oldest continuous rivalry, and the one many West Coast fans will tell you is actually the best.

The Dodgers and Giants have played each other more than 2,500 times, dating back to 1889 when they were the Brooklyn Bridegrooms and the New York Giants.

When the Dodgers moved to LA after the 1957 season, they convinced the Giants to move to San Francisco too, specifically to preserve the rivalry.

The feud became a California grudge layered on top of the pre-existing cultural rivalry between SF and LA. The on-field record is virtually dead even, currently tied at 1,287-1,287 all-time.

Oddly, for two teams that have faced each other thousands of times, they've only met once in the postseason (the 2021 NLDS). That rarity somehow makes every regular-season game feel bigger.

1. Yankees vs. Red Sox

The one everyone else gets measured against. Over 120 years of shared hatred, concentrated into the roughly 320km of interstate between Fenway Park and Yankee Stadium.

The rivalry has fuel going back to 1919, when the Red Sox sold Babe Ruth to the Yankees and allegedly kicked off the Curse of the Bambino.

Boston didn't win another World Series for 86 years. The Yankees, over that same stretch, won 26 of their 27 total championships.

The curse-breaking moment came in the 2004 ALCS, when Boston became the only team in MLB postseason history to come back from 3-0 down and win a best-of-seven series.

They beat the Yankees in seven, then swept the Cardinals for the title. For Red Sox fans, worth 86 years of suffering.

How to Watch MLB Rivalry Weekend in Australia

MLB's Australian broadcast rights sit with ESPN, so Foxtel subscribers and Kayo Sports streamers get the bulk of the live coverage.

On average, Kayo and Foxtel show between two and six live games per week during the regular season, and Rivalry Weekend typically gets more coverage than a standard weekend because of the marquee matchups.

Times are the main issue for Aussie fans. Most MLB games in May start between 9am and 2pm AEST depending on the US time zone, so weekend games land during prime viewing hours here. Friday night games in the US are Saturday morning for us.

Kayo Minis condense full games into 15-20 minute highlight packages if you want to keep up without blocking out the whole day. MLB TV subscriptions are also available direct if you want every game live and on-demand.
