Update: Bumgarner's agent, SFX Baseball Group, announced it's five-years, $35 million which is the largest guaranteed deal for a pitcher with more than 1 year of experience.
The San Francisco Giants have extended left-handed starting pitcher Madison Bumgarner, as first reported by John Shea of the San Francisco Chronicle. The club later confirmed the report and made the official announcement (via Twitter), announcing it's a five-year extension through 2017 with options covering 2018 and 2019 seasons. The agreement covers all of his arbitration years and his 1st year of free agency (2017), the Giants later tweeted.
Even without seeing the salary numbers, the Giants made a great move by locking up their young starter. Bumgarner could be the #1 starting pitcher for quite a few teams out there, at least a really good #2 for most teams and he's one of the youngest players in the game at just 22 years old.
At 21-years-old, he threw over 200 innings with a 3.21 ERA paired with a fantastic 8.4 K/9 and 2.0 BB/9. If you look at a few sabermetrics, he actually pitched better than his 3.21 ERA (2.67 FIP) and is predicted to pitch better than that as well (3.10 xFIP).
