Sibling rivalries always raise the stakes of competition, whether in the backyard or elsewhere. We’ve seen brothers face off in the Majors – a family pinnacle moment, for sure. But what about when that brotherly competition happens on the biggest stage, the postseason?

It’s hard to imagine a more exciting, rewarding or stressful moment for parents and other family members, knowing that one brother’s team will win a postseason series but the other’s will lose.

When they take the field on Tuesday, the Rays' Josh Lowe and the Rangers' Nathaniel Lowe will become the seventh set of brothers to face off in an MLB postseason series, including three in the World Series, according to Elias Sports Bureau research.

The Lowe brothers' clash during the Wild Card round comes with a little added weight compared to those before them. It was revealed Monday that their mother, Wendy, is battling cancer and undergoing chemotherapy.

Here’s a look at the pairs of brothers that came before them. To make this list, each brother must have appeared in at least one game in the series.

2022 NLCS: Aaron (PHI) vs Austin (SD) Nola

Aaron’s Phillies won this one in five games, advancing to the World Series. This duo is particularly notable because Aaron is a pitcher and Austin is a hitter. When older brother Austin came to bat against Aaron in the bottom of the second inning in Game 2, it was the first brother-vs-brother, batter-vs-pitcher matchup in postseason history. He hit a single in the fifth, going 1-for-2 in the series against his brother.

1996 ALDS, '97 ALCS,: Sandy Jr. (CLE) vs Roberto (BAL) Alomar

Roberto’s Orioles won the ‘96 series in four games, then Sandy’s Cleveland club won the ‘97 matchup in six. In the ALDS matchup, Roberto hit .294 with a home run and four RBIs. It wasn’t just any home run – it was a go-ahead in the top of the 12th in Game 4, proving to be the game-winning run for the series. His brother got two hits in that series, with three RBIs. The following year, Sandy got three hits in the postseason series opposite his brother, this time with a homer and four RBIs. His brother had four hits -- including a home run and two RBIs -- and seven walks.

1985 ALCS: Garth (TOR) vs Dane (KC) Iorg

Dane’s Royals won the series in seven games and went on to win the World Series. He appeared in four games in the ALCS opposite his brother’s Blue Jays, all as a pinch-hitter, and got one hit. He’d go on to play a key role in the Fall Classic, hitting a walk-off, two-run single in Game 6 to send the series to a decisive Game 7, where the Royals completed the 3-1 series comeback. In the ALCS, Garth played in six games and notched two hits.

1964 World Series: Ken (STL) vs Clete (NYY) Boyer

Ken’s Cardinals won the series in seven games, and he led the club in both homers (two) and RBIs (six). He hit a grand slam in Game 4, which St. Louis won, 4-3, after allowing all three runs in the first inning. And in Game 7, he hit a solo homer in the seventh to extend the lead to 7-3, which would provide some needed extra insurance as the Cards won, 7-5, to clinch. In the ninth, Bob Gibson allowed two solo homers before nailing down the complete game. The first was to Clete, marking the first time opposing brothers each homered in a postseason game.

1921-23 World Series: Bob (NYY) vs Irish (NYG) Meusel

Irish’s Giants won in 1921 and ‘22, before Bob’s Yankees won in ‘23 for the club’s first championship. There was no World Series MVP Award back then, but if there had been, it very likely could have been Irish in ‘21. He led the Giants with seven RBIs and was one of two on the team to homer, slugging .586 in the eight games. In the ‘22 series, he hit the team’s lone home run. In that series, Bob tied for the Yankees’ lead in hits, with six. In ‘23, he could have been MVP, leading the team with eight RBIs, seven of them in the final three games of the series. His three-run single in the top of the eighth in Game 6 capped off a five-run inning as the Yankees won, 6-4, to take the series.

1920 World Series: Doc (CLE) vs Jimmy (BRO) Johnston

Doc’s Cleveland club won the best-of-eight series in seven games. Doc played in five games, getting three hits and two walks. Jimmy played in four of the games, also getting three hits. He started Game 1 and Doc pinch-hit in the game in the ninth, marking the first time brothers each appeared in the same postseason game, whether on opposite teams or the same team.
