Correa played in four games for Triple-A Fresno, going 4-for-14 with four RBIs, before going 2-for-5 Thursday night for Corpus Christi.
The Astros also appear close to getting All-Star right-hander Lance McCullers Jr. back in the rotation. McCullers, who's been out since July 31 with back discomfort, has rejoined the team and could start Wednesday's series finale against the Mariners, Hinch said.
Correa, 22, was having a Most Valuable Player-caliber season for the Astros, hitting .320 with 18 doubles, 20 home runs and 67 RBIs in 84 games. McCullers is 7-3 with a 3.92 ERA in 19 starts this year, and he has been on the disabled list twice.
