SAN FRANCISCO (AP) -- Fernando Tatis Jr. hit a three-run homer in the third, Wil Myers added a two-run drive an inning later and the San Diego Padres spoiled San Francisco's home opener by beating the Giants 5-3.
Zach Davies struck out five over five innings to win his Padres debut. He allowed five hits and three runs -- two earned -- as San Diego won for the fourth time in five games this season.
The right-hander came over in a trade with Milwaukee last November.
Tatis Jr.'s opposite field home run was his first of the season. Myers' blast was his second of the year.
