Los Angeles Dodgers shortstop Corey Seager is having an awesome rookie season, hitting .322 with 22 home runs and on pace to score more than 100 runs. Older brother Kyle Seager of the Seattle Mariners is having a terrific season as well, on pace to hit 30 home runs and top 100 RBIs -- not that anybody is talking much about him. In fact, Kyle ranks seventh among all position players in WAR (5.7), and Corey (5.3) ranks 10th.

So, inquiring minds want to know: Where does this rank among the best brother seasons ever? Let's do some digging. Note that some of the best brother combos never managed to align their best seasons -- such as Pedro and Ramon Martinez -- and I didn't consider cases where one brother was a star and the other wasn't, such as Cal and Billy Ripken.

Paul and Lloyd Waner (1927)

The only brothers in the Hall of Fame, Paul was a legitimate star, but Lloyd is one of the worst Hall of Famers, a singles-hitting outfielder who hit .300 in an era when everyone hit .300. They were longtime teammates with the Pirates, Lloyd in center field, Paul in right.

For their best season, I'd go with 1927, when the Pirates reached the World Series. Paul was in his second season and won NL MVP after leading the league in batting average and RBIs, and Lloyd was a rookie who led the league with 133 runs.

Paul: .380/.437/.549, 9 HR, 131 RBIs, 6.9 WAR

Lloyd: .355/.396/.410, 2 HR, 27 RBIs, 2.7 WAR

Dizzy and Paul Dean (1934)

They famously led the Cardinals to the 1934 World Series title as Dizzy teamed up with rookie Paul (who was sometimes called Daffy):

Dizzy: 30-7, 2.66 ERA, 311.2 IP, 8.5 WAR

Paul: 19-11, 3.43 ERA, 233.1 IP, 4.9 WAR

There wasn't a Cy Young Award then, but Dizzy won MVP, and Paul finished ninth. In the World Series, each won two games as the Cardinals beat the Tigers in seven games. Dizzy would make the Hall of Fame, and Paul would win 19 games again in 1935 before getting injured.

Joe and Dom DiMaggio (1941)

Joe, of course, is a legendary Hall of Famer, but younger brother Dom was an excellent player as well, a seven-time All-Star despite missing three years because of World War II. They were also rivals, with Joe patrolling center field for the Yankees and Dom for the Red Sox. They both crossed 5.0 WAR in 1942, although their highest combined WAR came in 1941 ... which also happened to be the best season for a third brother, Vince:

Joe: .357/.440/.643, 30 HR, 125 RBIs, 9.1 WAR

Dom: .283/.385/.408, 8 HR, 58 RBIs, 3.0 WAR

Vince: .267/.354/.456, 21 HR, 100 RBIs, 3.7 WAR

Joe and Dom made the All-Star team, and Joe won MVP honors over Ted Williams thanks to his 56-game hitting streak.

Ken and Clete Boyer (1962)

Both outstanding defensive third basemen (although because of Brooks Robinson, Clete didn't win a Gold Glove until he went to the NL late in his career), Ken also won an MVP Award in 1964 with the Cardinals. Clete had a decent year at the plate with the Yankees in 1962:

Ken: .291/.369/.470, 24 HR, 98 RBIs, 5.6 WAR

Clete: .272/.331/.413, 18 HR, 68 RBIs, 4.6 WAR

Felipe and Matty Alou (1968)

They once teamed with brother Jesus in the same Giants outfield, but Felipe and Matty were both great in 1968 (the year of the pitcher), Felipe with the Braves and Matty with the Pirates:

Felipe: .317/.365/.438, 11 HR, 57 RBIs, 6.5 WAR

Matty: .332/.362/.396, 0 HR, 52 RBIs, 5.3 WAR

They finished second and third in the batting race behind Pete Rose.

Gaylord and Jim Perry (1970)

The only brothers to win Cy Young Awards, they finished just behind the Niekros with 529 wins. Gaylord won his first of two Cy Youngs in 1972 with the Indians, with an absolute monster 11.0 WAR season, but Jim didn't have one of his best seasons. They were teammates with the Indians in 1974 and combined for 38 wins and 12.9 WAR. In 1969, Gaylord had a 6.5-WAR season and Jim a career-best 6.2. But both nearly won the Cy Young Award in 1970:

Gaylord: 23-13, 3.20 ERA, 328.1 IP, 7.6 WAR

Jim: 24-12, 3.04 ERA, 278.2 IP, 3.8 WAR

Both led their respective league in wins, Jim won the AL Cy Young, and Gaylord finished second in the NL voting.

George and Ken Brett (1976)

This is fun, because one was a hitter and one was a pitcher (although Ken was a good hitting pitcher). George had his breakout season in 1976 when he won his first batting title, and Ken had his best season:

George: .333/.377/.462, 7 HR, 67 RBIs, 7.5 WAR

Ken: 10-12, 3.32 ERA, 203 IP, 4.1 WAR

Phil and Joe Niekro (1979)

The knuckleballing brothers combined for 539 wins, with Hall of Famer Phil winning 318. Joe reached the majors as a conventional pitcher, began throwing the knuckleball in 1971 and had perfected it by the late '70s. How about 1979:

Phil: 21-20, 3.39 ERA, 342 IP, 7.6 WAR

Joe: 21-11, 3.00 ERA, 263.2 IP, 3.5 WAR

They tied for the league lead in wins with Joe finishing second in the Cy Young voting for the Astros and Phil, pitching on a terrible Braves team, finishing sixth. Joe's best season was 1982 (6.8 WAR), and Phil went 17-4 that year with a 3.65 ERA.

Sandy Alomar and Roberto Alomar (1997)

Sandy made six All-Star teams and Hall of Famer Roberto made 12, so they must have had some great seasons, right? Well, the whole Sandy Alomar All-Star thing never made sense at the time, as he was often injured and finished his career with just 13.7 WAR. His best season was 1997, but Roberto was injured that year and played just 112 games, cutting into his overall value:

Sandy: .324/.354/.545, 21 HR, 83 RBI, 3.9 WAR

Roberto: .333/.390/.500, 14 HR, 60 RBI, 3.4 WAR

Brian and Marcus Giles (2003)

A surprise entrant, but Marcus did have one big season in 2003 (although Brian had better years):

Brian: .299/.427/.514, 20 HR, 88 RBIs, 4.5 WAR

Marcus: .316/.390/.526, 21 HR, 69 RBIs, 7.8 WAR

Corey and Kyle Seager (2016 -- through Aug. 25)

Corey: .322/.377/.538, 22 HR, 61 RBIs, 5.3 WAR

Kyle: .286/.364/.516, 24 HR, 83 RBIs, 5.7 WAR

What makes the Seager brothers so impressive is that both are going to pass 6.0 WAR -- the only other example I found was the Perry brothers in 1969 -- with a chance to reach 7.0 WAR. It's hard to beat what the Dean brothers did in 1934, teaming up to win a World Series, but Corey and Kyle might be having the best brother season ever.
