Madison Bumgarner Is Back to October Bumgarner
Madison Bumgarner has been having quite a month of August. He’s posted a 53:4 strikeout-to-walk ratio while allowing only six earned runs in 37.2 innings, and he’s looked almost as unhittable as he did last October, when he relentlessly took the ball for the Giants in high pressure situations during the playoffs. That’s not a coincidence, it turns out, as Bumgarner is currently exhibiting tendencies that are quite similar to the 2014 postseason version of himself.
Before we go down that particular road, let’s have a brief introduction to Bumgarner, 2015 starting pitcher. On these digital pages, we’ve featured an article on how well he hits — which is quite well indeed — but not much else in the way of analysis this season; I will remedy that fact in a brief, limited manner. We could spend an entire article about the minute changes Bumgarner has made in 2015. Instead, here’s a cliffs notes version:
- He’s throwing more fastballs than at any point since 2011.
- He’s basically ditched his changeup, as he’s relied almost strictly on a three-pitch combination of fastball, slider (referred to at times as a cutter), and curveball in 2015. Here is his pitch usage since 2010, his first semi-full season in the majors (courtesy of Brooks Baseball, which calls his slider a cutter):
- Finally, his command improvements from last season have stuck, as he’s posting a career-low walk rate (4.3%) and career-high strikeout rate (27.4%).
These are all good things. By the numbers, Bumgarner is perhaps the best version of himself that he’s ever been, and it shouldn’t be a surprise that he’s posting the best xFIP of his career while challenging his best in ERA and FIP.
That’s why this month has been extra interesting; because, in the midst of one of his best seasons, Bumgarner seems to be up to something. And that something just happens to be intentionally throwing slower.
