His two-run double in the bottom of the 5th capped a comeback win over Grosse Pointe, MI in a consolation game in the 2013 Little League World Series.  It was the first win ever for a Czech team in a Little League World Series.

He was 0-1 with a 4.91 ERA for the Czechs in the 2018 European Junior Championship; they finished third and his loss came to second-place Spain. 
Hlouch was 4-6 with a save and a 3.12 ERA for the 2018 Nuclears.  He was a late addition to the Czech team for the 2018 Super6; he was the team's youngest player. He debuted for the national team in a loss to Spain, relieving Ondřej Furko with a 11-3 deficit in the 7th and allowing only one unearned run in three innings, on three hits and a walk while fanning two (Richard Montiel and Eric Segura).  He was one of two Czechs to make the World Select Team for the Arizona Fall Showcase, an event highlighting top amateur prospects; Daniel Padyšák was the other Czech player.
