The One Optimization Germán Márquez Can Make
We at FanGraphs haven’t checked in on the Rockies in a while. To put it nicely, that’s because they are performing as expected – a 43-55 record has banished them to fourth in the NL West, a place the team will probably call home for the remainder of the season. As a whole, the Rockies have a league-trailing 75 wRC+. It is not a good sign when C.J. Cron is the best hitter on your team by a wide margin.
But the pitching? After adjusting for the wackiness of Coors, the Rockies’ pitching staff has an ERA- of 100. It also has a FIP- of 101. I suppose one could do better than that, but one could also do worse, and being an average arm in Denver is an accomplishment of its own.
A major reason for this is the resurgence of Germán Márquez. After a rocky April and May, it’s safe to say the Rockies’ most reliable pitcher has settled in. What do we know about Márquez? There are his two breaking pitches, a curveball and a slider, each one a plus offering that hitters whiff at over 40% of the time. But what’s not talked about as often is his four-seam fastball. That in itself isn’t surprising, since the fastball has long been Márquez’s worst pitch. What is surprising, though, is how good it’s been in recent months. Consider the plot below:
Márquez is the point in yellow. Since June 1 (and through last Thursday’s action), his four-seamer has averaged the lowest launch angle among the 97 shown. It has averaged the lowest wOBA, too, a result of the first fact. The pitch has always induced groundballs at a healthy rate, but that quality seems to have been kicked into overdrive during this two-month stretch. Read the rest of this entry »
