Schwarber had the sixth three-homer game since the franchise moved to Washington for the 2005 season, the first since Anthony Rendon's 10-RBI game against the Mets on April 30, 2017.

Schwarber's third homer followed a pinch-hit double by Gerardo Parra, a 34-year-old fan favorite who returned to the Nationals on Sunday when his contract was selected from Triple-A Rochester. Parra's walkup music of the children's song “Baby Shark” became a theme of the Nationals’ run to the 2019 World Series title, and it sounded before his at-bat to the crowd's delight.

Parra spent last season with the Yomiuri Giants in Japan, then signed a minor league contract with the Nationals last winter.
