Duffy went 2-for-5 with the game-winning double in a 2-1 victory over the Rockies on Saturday.
The Giants third baseman is on a nice streak at the moment, but he has been wildly inconsistent to begin the year. He is 7-for-14 (.500) in the last three games, but he was 0-for-10 in the previous three games. In the middle of April, Duffy went through a 0-for-13 stretch, but followed that up with three straight multi-hit games. Until he shows more consistency at the plate, it's hard for fantasy owners to count on him night in and night out.
