If the Mets were seeking a top prospect with superstar bloodlines to help replenish their farm system, they could have done far worse than landing Luisangel Acuña.

Steve Cohen and the Mets paid a heavy price to acquire the 21-year-old younger brother of Braves’ MVP candidate Ronald Acuña Jr., who was the lone return in the blockbuster trade Saturday night of co-ace Max Scherzer to the Rangers, according to The Post’s Joel Sherman.

The 21-year-old shortstop and second baseman was ranked the third-best prospect in the Rangers’ farm system, and the 44th-best in all of baseball.

The Mets’ top two prospects, according to MLB Pipeline, are Single-A catcher Kevin Parada (39th overall) and Triple-A shortstop Ronny Mauricio.

The Mets had to pay down much of Scherzer’s remaining contract, including the $43.3 million option for 2024 that the three-time Cy Young winner picked up, to complete the deal.

The Rangers will be responsible for roughly $22.5 million through 2024, while the Mets will pay about $36.6 million of the remaining $59.1 million left on Scherzer’s pact.

The younger Acuña has a slash line of .315/.377/.453 with 25 doubles, seven home runs, 51 RBI and 42 stolen bases in 84 games for Double-A Frisco this season.

Everything to know about the Mets' historic sell-off

After a disappointing season, the Mets are selling off their historically expensive roster.

The Amazins dealt out some big name players before the MLB trade deadline — including now-former co-aces Justin Verlander and Max Scherzer.

Below are the players the Mets have shipped out:

Tommy Pham

The Mets traded the outfielder minutes before the 6 p.m. deadline to the Arizona Diamondbacks.

Arizona is sending back 17-year shortstop Jeremy Rodriguez, who has a .751 OPS rookie ball this season.

Justin Verlander

The Mets traded out Verlander, a sure-fire Hall of Fame pitcher, back to his former team, the Houston Astros.

The Amazins reportedly will receive top Astros prospect Drew Gilbert, a Double-A outfielder, and 20-year-old outfielder Ryan Clifford, who owns a .919 OPS through 83 games in Low- and High-A this year.

Max Scherzer

Scherzer, a three-time Cy Young winner that was a co-ace with Verlander, was sold off to the Texas Rangers.

The Mets landed one of the Rangers’ top prospects, Double-A infielder Luisangel Acuña, brother of Braves star Ronald Acuña.

Mark Canha

The veteran outfielder was dealt to the Brewers for Justin Jarvis, a promising 23-year-old pitcher that was ranked No. 12 in the Brewers’ farm system.

David Robertson

The Mets traded closer David Robertson to the Miami Marlins, a move that started off the club’s deadline dismantle.

In exchange for Robertson, who is having another terrific season, the Mets received a pair of minor leaguers, infielder Marco Vargas and catcher Ronald Hernandez, from Miami.

“My brother is more advanced and better than I was at his age,” Ronald Acuña Jr. told The Dallas Morning News through an interpreter earlier this year. “Maybe I was as talented but not as advanced.”

The Braves’ Acuña is having an MVP-caliber season for the NL East leaders, with 24 home runs, 50 stolen bases and a .993 OPS through 102 games. Of course, he already copped NL Rookie of the Year honors (2018) and made his first of four career All-Star appearances during his age 20 and 21 seasons, respectively.

Luisangel Acuña found himself roadblocked in the middle infield with the Rangers, who signed shortstop Corey Seager to a 10-year deal worth $325 million and second baseman Marcus Semien to a seven-year deal worth $175 million ahead of last season.

He was promoted to the Double-A Texas League for 37 appearances last year after starting the season at High-A Hickory of the South Atlantic League.

Acuña signed out of Venezuela in 2018 for $425,000. That’s more than four times the $100,000 bonus Atlanta gave his brother as a 16-year-old in 2014, before he inked an eight-year deal worth $100 million guaranteed with the Braves in 2019.
