The Giants and right-hander Santiago Casilla have agreed to a three-year, $15MM contract with a vesting option for a fourth season. The deal will pay Casilla $4.5MM in 2013 and 2014 and $5MM in 2015, plus a $1MM buyout for 2016 if his option doesn't vest. Casilla is represtented by ACES. 
The 32-year-old right-hander pitched to a 2.84 ERA with a 7.8 K/9, 3.1 BB/9 and 55 percent ground-ball rate in 63 1/3 innings for the World Champion Giants in 2012. In three seasons with the team, Casilla has a 2.22 ERA over the course of 170 1/3 innings.
Casilla took over as the team's closer when Brian Wilson went down with Tommy John surgery early in the season and led the Giants with 25 saves on the year. As a result, MLBTR contributor Matt Swartz projected that Casilla would earn $5.4MM in his third year of arbitration eligibility. The contract buys out that final year of arbitration and gives the Giants control over two of Casilla's free agent seasons, with an option for a third.
As MLBTR's Transaction Tracker shows, Giants general manager Brian Sabean has done his best to keep his World Series winning roster together this offseason. He's brought back Jeremy Affeldt and Marco Scutaro on three-year deals and re-signed Angel Pagan to a four-year deal. Sabean also signed Andres Torres to a one-year deal, who was a part of San Francisco's 2010 World Series team.
