Giants utility infielder Matt Duffy is officially in the starting lineup for Saturday's game against the Padres and will bat seventh, reports the San Francisco Chronicle.
Duffy, who has also started at second base early in the season, will fill in for the injured Brandon Belt after he was placed on the 15-day DL. It will be his first career start at first after playing the 17 games at second base and shortstop. He is a career .284 hitter with three doubles and nine RBI.
