If you take a look at FanGraph's Roster Resource (an essential, go-to site) you'll see that the 2022 Giants lineup will look a lot like the 2021 Giants lineup. The team's starting rotation got a makeover after the departures of Kevin Gausman and Johnny Cueto but the bullpen stayed pretty much intact. In fact the team added significant pitching depth what with Alex Cobb, Carlos Rodon, Matthew Boyd, Jakob Junis, and Carlos Martinez all joining in the off-season.
The lineup's only new face is Joc Pederson. It's a bit underwhelming. The team has three of LH OFs already, namely Mike Yastrzemski, Steven Duggar, and LaMonte Wade, Jr.
