I mean, the released players weren't making much. Finnegan is making 6 and Chafin is making 1. Everyone else is making the minimum.
Sims and Lopez made $3 million each. Poche was signed to a minor league contract, but upgraded when he made the 40-man.
You also missed Derek Law who's making $2.75 million. So they started the season with five players making more than minimum. The Giants have/had two and a 2.99 bullpen ERA.
