4. Sergio Romo
The Giants were fortunate to have right-handed reliever Sergio Romo for their championship runs. He was a key part of the "Core Four" in the bullpen and delivered huge outs for the team in the postseason, none bigger than this one.
His lively personality coupled with his wicked slider made him an absolute delight to watch during his time with the Giants. While he has never quite been as consistently good as he was during his time with the Giants, he has still been a solid relief pitcher for a number of teams since he left San Francisco back in 2017.
Last season as a member of the Oakland A's he had an ERA of 4.67 with 60 strikeouts in 61 and 2/3 innings pitched. Those numbers are far from outstanding, but they are respectable for a reliever nearing the end of his career.
Romo could possibly fit in the Giants bullpen on a one year deal, but given that their bullpen was a strength last year and they had younger right-handed relievers like Tyler Rogers, Camilo Doval, and Dominic Leone to rely on, a reunion seems unlikely.
Despite this, Romo definitely deserves another chance as a reliever if he wants it. His slider still makes him a difficult guy to face and his lack of IL time over the years makes him a guy worth taking a shot on.
In sum, we have covered four former SF Giants fan favorites that are free agents. While they may not be on their way back to San Francisco, they still deserve a shot to prove themselves in the big leagues. And no matter what, they are Forever Giants.
