The 26-player MLS squad will face the Mexican League All-Stars on August 10 at St. Paul, Minnesota.
It’s the second consecutive year the MLS and Mexican League elite lineups will meet. They played to a 1-1 draw last year at Los Angeles before the MLS won 3-2 on penalties.
Hernandez — whose stops have included Manchester United, Real Madrid, Bayer Leverkusen and West Ham United — has 26 goals over three seasons with the Galaxy. The 34-year-old from Guadalajara has seven goals in the current campaign.
Vela, who has had extended stays with England’s Arsenal and Real Sociedad in la Liga, has 63 goals in five seasons with LAFC, this season’s league leaders.
LAFC and reigning MLS Cup holder New York City FC each had an MLS-best three players on the squad, with 2021 top MLS scorer Taty Castellanos among those representing the defending champions.
Other standouts selected include US forward Jesus Ferreira of Dallas, American center back Walker Zimmerman of Nashville and Canadian center back Kamal Miller of Montreal.
The roster was selected through a combination of fan, player, and media voting, nods from All-Star coach Adrian Heath of host club Minnesota United and two picks by MLS commissioner Don Garber.
