Ruggiano went 1-for-3 with a solo home run during Saturday's win over Cincinnati.
Ruggiano just joined the Giants on May 6, and he's only started four games and made 20 plate appearances since. The 35-year-old veteran has historically been a solid contributor against left-handed pitchers (.276/.341/.527 career slash line), so he'll probably receive some starts against southpaws going forward. However, barring a long-term injury to another outfielder, Ruggiano is unlikely to be an everyday player.
