The SF Giants won 107 games in 2021, but they lacked at one position over all of the others: second base. Using WAR [Wins Above Replacement] as a barometer, the Giants were top-15 in the league at every position with the exception of second base and designated hitter (duh).
7 SF Giants second base options to consider for 2022
In total, Giants second basemen in 2021 hit 19 home runs (which was 12th in baseball) while driving in 71 runs (13th), and batting .254 (20th). For reference, their offensive WAR came out to be a total of 2.6, which was ahead of Washington -- who won 65 total games -- and behind Pittsburgh, who won only 61 games (it helps to have Kevin Newman anchoring that position). Needless to say, not all wins are created equally, and WAR for a particular position is not the final outcome for team success.
What we can gather from the info above is that offensive production by the second baseman for the Giants in 2021 was average at best. There were six total players who started a game at second base. However, only two of them had more than 100 plate appearances: Donovan Solano and Tommy La Stella.
On defense, Solano and La Stella are both below-average defenders with a combined -0.7 dWAR in 2021 to back up that claim. Wilmer Flores won't get much mention in this piece because he only had 87 plate appearances while at second base, so he might be under consideration for the spot, but we shall see.
Farhan Zaidi has shown while with the Giants he wants to operate like there is a tight budget even if there is not and spend the big bucks only when he feels like it is absolutely necessary. There was reported interest in Marcus Semien before he signed with Texas, so the bread crumbs lead us to believe the Giants are looking to upgrade that spot.
