Correa is expected to receive $1 million in 2018, just below the $1.05 million that third baseman Kris Bryant received in '17 from the Cubs, while Bregman is expected to earn just under $600,000.
Both Correa (2012) and Bregman ('15) were first-round Draft selections by Houston and played major roles in helping the franchise capture its first World Series title.
Correa, the 2015 American League Rookie of the Year, batted .315/.391/.550 with 24 home runs and 84 RBIs in 109 games for the Astros in '17 while being named to the AL All-Star team. The 23-year-old has hit .288/.366/.498 with 66 homers and 248 RBIs in 361 games across three Major League seasons, all with the Astros.
Bregman, also 23, hit .284/.352/.475 with 19 homers and 71 RBIs in 155 games for the Astros last season. He hit a walk-off single off Dodgers closer Kenley Jansen to win World Series Game 5.
Correa and Bregman combined to hit nine homers and drive in 24 runs during the Astros' 2017 postseason run.
