Caden Clark made MLS history as New York Red Bulls and high-flying Toronto drew 1-1, while it was a bad day for both Los Angeles teams.
Clark – aged 17 years, four months and 18 days – became the youngest player to score in his first two MLS appearances on Wednesday, per Opta.
Hours after joining the Red Bulls, Clark capped his debut with a goal in Saturday's 1-0 win over Atlanta United.
Clark became the youngest player to score his maiden goal for the Red Bulls since Jozy Altidore in 2006.
He continued where he left off against Toronto, netting the equaliser with 13 minutes remaining midweek.
Following Alejandro Pozuelo's 23rd-minute penalty, Clark earned the visiting Red Bulls a point by firing a shot into the top corner of the net from outside the box.
The Red Bulls are seventh in the Eastern Conference, while Toronto – already play-off bound – remain top through 18 games.
Elsewhere, reigning Supporters' Shield holders Los Angeles FC and struggling LA Galaxy were beaten.
Lucas Cavallini's brace lifted Vancouver Whitecaps to a 2-1 victory against fourth-placed LAFC.
Canada international Cavallini has now scored in back-to-back games after finding the net just twice in his first 11 MLS matches for the Whitecaps, who climbed up to eighth in the standings and in the play-off positions.
As for the Western Conference's bottom side – the Galaxy – they were swept aside 4-0 by San Jose Earthquakes in the Cali Clasico.
Former Manchester United and Real Madrid striker Javier Hernandez was substituted early in the second half, with the Galaxy only managing four goals in the 652 minutes 'Chicharito' has been on the pitch this season.
It was a sixth consecutive defeat for the slumping Galaxy as the Earthquakes moved within a point of LAFC in the west.
Wednesday's scheduled Minnesota United-Chicago Fire fixture was postponed due to a suspected coronavirus case among Minnesota's team delegation.
