LEIPZIG, Germany — Not too shabby, not too shabby at all.

Only a half hour in his first start for Borussia Dortmund, midfielder Gio Reyna managed to make an impact.

The 17-year-old Westchester, N.Y. native assisted on the first of two Erik Haaland’s goals in the 30th minute in the club’s 2-0 victory over Red Bull Leipzig in Bundesliga action Saturday.

It was the first time a team blanked Leipzig at home this season.

Reyna had come close to playing twice for Borussia, which clinched second place with the win. On May 16, the son of former U.S. international captain Claudio Reyna and ex-U.S. national team player Danielle Egan was ready to make his Bundesliga first start but he injured himself during the pregame warm-up in the match vs. Schalke 06. On Wednesday, Reyna missed Dortmund’s 2-0 defeat to Mainz due to a bacterial infection.

The midfielder was yellow-carded early in the final half for a late challenge on Nordi Mukiele.

Reyna has played 17 times for Dortmund across all competitions — 16 as a sub this season. In his Dortmund debut on Jan. 18, he became the youngest American to play in the Bundesliga at 17 years, two months and five days. Several weeks later on Feb. 4, he connected for his first goal in a German Cup loss to Werder Bremen.
