Pretty much ever since Brian Wilson went down with his shoulder injury at the start of 2012, the Giants have used a few different guys to close out games. Sergio Romo and Santiago Casilla, career set-up guys, basically shared the duties, with Casilla becoming Bochy's #1 choice the last couple seasons. But after that epic second half collapse, largely attributed to that bullpen, and the team getting knocked out in the NLDS because of the bullpen, the Giants made solidifying that 9th inning as their number one priority this winter.
On Monday, the Giants finally found a guy they hope is their answer to their ninth inning woes that reared their ugly head in 2016, signing Mark Melancon to the richest contract in relief pitcher history (although both Kenly Jansen and Aroldis Chapman will most likely set new records after they sign).
