Zack Greinke has been the most valuable National League pitcher this season, tallying 3 WAR over 13 starts. Not too far behind him is a pair of Washington Nationals starters who have each made one fewer start: Gio Gonzalez ranks second with 2.7 WAR and Stephen Strasburg comes in third with 2.6 WAR. At this point in the season the 0.3 wins separating Greinke and Gonzalez isn’t significant, nor is the more minute differential between Strasburg and his southpaw teammate.
But the fact that Gonzalez is even in the same discussion as a former Cy Young Award winner and a phenom living up to the hype bears notice. Entering the season, the 26-year old Gonzalez was considered a good pitcher, one who could easily miss bats but who struggled with control and was prone to racking up walks. He wasn’t projected to pitch at an all-star or award-worthy level, but the Nationals saw something they loved and offered, at signing, the largest-ever contract for a first-time arbitration-eligible pitcher.
His five-year, $42 million deal, which includes a $12 million club option in 2017 and a $12 million player option in 2018, stood to buy out the most effective years of what we typically consider a #2 or #3 starter. The deal offered some savings at the end if Gonzalez turned into an ace, but would still prove worthwhile if he sustained the 3-3.5 WAR performance he established over 2010-11.
If Gonzalez can sustain his current level of performance, or some semblance of it, the Nationals are going to have a legitimate second ace in the rotation and a potential #1 starter signed to a fairly modest deal throughout his prime.
Can Gonzalez keep rolling through the National League at this pace? While there are a couple of reasons to think some of his numbers will regress to the mean, there is also ample evidence to suggest he has made long-lasting improvements and isn’t simply a posterchild for switching to the easier league.
