Among the many players acquired for The San Francisco Giants 2019 outfield a few stand out either because of their special roster status or major league track record.
Drew Ferguson was acquired via the Rule 5 Draft and thus must stay on the 25 man roster all season and be active for at least 90 days for the club to keep him. This, along with his defensive versatility and good minor league on base percentage, give him a special edge in making the final roster. Plus, the fact that he can play center and is a right-handed hitter makes him an ideal backup to Steven Duggar.
Veteran left-handed hitter Gerardo Parra is another versatile outfielder with a good major league track record who has played well against the Giants over the years. And, although his power numbers have declined the past few years, he has still shown a good ability to get on base and seems quite capable of playing defense in the difficult Oracle Park right field.
Veterans Cameron Maybin and Craig Gentry are both right-handed hitting outfielders who, even in their thirties, still have the speed to play center field. So, like Drew Ferguson, both are a perfect backup/compliment for Steven Duggar in center field with Maybin having the edge over Gentry because of his better overall versatility.
I think new switch hitting infield acquisition Yangervis Solarte should also be mentioned here as the club loves his bat and may try to work him into the left field mix.
With so many outfield candidates in camp long shots like John Andreoli, Mike Gerber, Henry Ramos, and Anthony Garcia hardly seem worth mentioning. However, things are so wide open that a great spring by any one of them could lead to a roster spot.
