SAN DIEGO — Slugger Manny Machado of the San Diego Padres sat out against the San Francisco Giants after Major League Baseball upheld his one-game suspension for a confrontation with an umpire.

Machado was suspended for “aggressively arguing and making contact” with plate umpire Bill Welke after being called out on strikes at Colorado on June 15.

Machado, who signed a $300 million contract during spring training, appealed the suspension, denying he made contact.
