A malfunctioning trumpet threatened to bring the national anthem to an abrupt stop before an Arizona Diamondbacks game, but Dr. Jesse McGuire refused to let the moment fall apart. After unsuccessfully trying to correct the problem, the veteran musician lowered his instrument, grabbed the microphone, and began singing “The Star-Spangled Banner” himself. McGuire carried the anthem through its final lines as a massive American flag waved across the outfield. His quick recovery earned a standing ovation from the sellout crowd at Chase Field.
The performance came before the Diamondbacks faced the New York Yankees in Phoenix on Saturday, September 19, 2026. Arizona was commemorating the 25th anniversary of its 2001 World Series championship, with players and other members of that team returning for the occasion. McGuire had performed the national anthem repeatedly during the 2001 postseason and was invited back as part of the celebration. The anniversary opponent was fitting, as the Diamondbacks defeated the Yankees in seven games to capture that championship.
The clip begins with McGuire playing the anthem alone on the field as players, coaches, and fans stand at attention. Roughly halfway through the song, the trumpet begins giving him trouble and the notes stop coming through properly. McGuire pauses, attempts to fix the instrument, and briefly tries playing again before realizing the problem will not be corrected in time. He then reaches for the nearby microphone and continues the anthem with his voice where the trumpet had failed.
McGuire didn’t leave the crowd waiting for an explanation or signal for someone else to take over. He simply began singing and pushed through the demanding final section of the anthem, reaching the song’s highest notes in front of the packed stadium. As MLB reported, the performance ended with a standing ovation from the crowd. Diamondbacks manager Torey Lovullo also sought McGuire out as he left the field and commended him for the quick recovery.
The 68-year-old musician already had a long history with the Diamondbacks before Saturday’s unexpected moment. McGuire performed the anthem numerous times during Arizona’s 2001 postseason run, including before the decisive Game 7 of the World Series. The organization came to regard him as a good-luck charm and even presented him with a World Series championship ring. He has since returned for the reunions held every five years by former managing general partner Jerry Colangelo and former team president Rich Dozier.
McGuire’s career extends well beyond his connection to the Diamondbacks. He formerly served as lead trumpeter for the Lincoln Center Jazz Orchestra in New York City and also played with the celebrated funk and soul band Tower of Power. His experience showed when the instrument failed, as he shifted from playing to singing without letting the ceremony grind to a halt. The crowd briefly cheered when he picked up the microphone before falling quiet again as he finished the anthem.

The Diamondbacks followed the dramatic opening with an equally memorable finish against the same franchise they defeated for the 2001 title. Arizona beat the Yankees on a two-run home run by Pavin Smith in the bottom of the ninth inning. The walk-off victory kept the Diamondbacks’ postseason hopes alive and gave the returning members of the championship club another late-game celebration at Chase Field. In 2001, Luis Gonzalez had delivered the championship-winning hit against Yankees closer Mariano Rivera in the bottom of the ninth inning of Game 7.
McGuire’s work at the ballpark also wasn’t finished after the national anthem. He returned during the seventh-inning stretch to perform “God Bless America” before the same crowd that had watched him rescue his earlier appearance. McGuire took the microphone again for that performance. He sang the entire song.
