Right-hander Johnny Cueto decided Saturday night to not opt out of the final four years and $84 million of his contract with the Giants.
Cueto, 31, went 8-8 with a 4.52 ERA for San Francisco in 2017, dealing with a forearm injury that sidelined him from mid-July through August. In 2016, the two-time All-Star went 18-5 with a 2.79 ERA in 32 starts.
Prior to being traded to the Royals and helping Kansas City win the World Series in 2015, Cueto posted a 3.21 ERA with a 7.5 K/9 rate in eight seasons with the Reds.
