The starting lineups for the contest in Cleveland have also been released.
AL All-Star team manager Alex Cora joked with Verlander about being the "opener" after the eight-time All-Star asked him about it.
"You know what? You are. You are the opener," Cora replied, according to Evan Woodbery of mlive.com.
Verlander, 36, will start the Midsummer Classic for the second time in his career - he got the nod for the first time in 2012. Ryu will be the first Korean-born pitcher ever to start an All-Star Game, according to MLB Stats.
Both pitchers have had outstanding seasons so far with Verlander accruing a 2.98 ERA with 153 strikeouts - second most in the AL. Ryu, a first time All-Star, leads the majors with a 1.73 ERA and a stunning 0.82 BB/9 rate.
