The Giants have included infielder Matt Duffy and pitchers Jean Machi and George Kontos on the Opening Day roster, the team announced Sunday.
Machi and Kontos could eventually be battling for the same bullpen spot, but the team has decided to carry 13 pitchers at the beginning of the season. Duffy earns a bench spot over Ehire Adrianza after hitting .361/.400/.639 with three home runs in 61 spring at-bats.
Adrianza was designated for assignment Sunday.
