The Czech Republic got a five-minute man advantage when U.S. forward Ryan Poehling was given a major penalty and a game misconduct for spearing. Machala one-timed a pass from the slot past U.S. goalie Cayden Primeau to take a 4-3 lead.
Machala (5-foot-11, 172 pounds) plays for Pardubice in the Czech junior league and is on NHL Central Scouting's Futures List for the 2017 draft.
Filip Zadina, a 2018 draft prospect, scored two goals for the Czech Republic, and Filip Chytil also scored. Goaltender Jakub Skarek made 23 saves.
Mick Messner had a goal and an assist for the U.S., and Sasha Chmelevski and Thomas Miller also scored. Primeau made 29 saves. Messner, Chmelevski, Miller and Primeau, the son of former Philadelphia Flyers captain Keith Primeau, also are on the Central Scouting Futures List for the 2017 draft.
"Our team competed real hard," U.S. coach Clark Donatelli told the USA Hockey website. "We didn't get the result we wanted but all of the guys should be very proud of themselves for the way they represented their country."
Chmelevski, a 5-11, 188-pound center, led the tournament with five goals and 10 points in five games. A native of Huntington Beach, Calif., he had 11 goals and eight assists in 34 games with Sarnia and Ottawa of the Ontario Hockey League last season.
Andrei Svechnikov, a 2018 draft prospect, had two goals and an assist to help Russia defeat Sweden 6-3 in the bronze-medal game Saturday. Svechnikov, who will play for Muskegon in the United States Hockey League this season, is the younger brother of Detroit Red Wings prospect Evgeni Svechnikov.
