Jos lvarez pitched well last season in his debut for the Giants. The rookie allowed just five runs on four hits while striking out six and walking one. He was a solid starter in 2018, allowing only seven earned runs in 54.1 innings. Despite his limited at-bats, Alvarez pitched well enough to earn a hold in the 12-3 win over the Nationals. While he may not see many save opportunities, he is an opportunistic addition to any rotation.
