Harrison Bader connected against Walker Buehler for San Francisco's first home run this season and the Giants held off a late rally by the San Diego Padres to give rookie manager Tony Vitello his first victory, 3-2 on Monday night. Ryan Walker was one strike from closing a two-hit shutout when he allowed a two-run homer to Jackson Merrill. Walker then got Xander Bogaerts to ground out to finish the combined three-hitter for a save.
