Checking in on Didi Gregorius

Back on July 15, I wrote about the slow and steady progression of Didi Gregorius so I thought in light of last night's performance and his performance against the Braves this past weekend, we could take a look at how he has been doing since the All-Star break. In 147 at bats (42 games), Gregorius is hitting .327/.365/.435/.800. He's batting .233/.273/.315/.588 at home and batting .419/.451/.554/1.005 away from Yankee Stadium.

Here's his overall spray chart since the All-Star break: export (67)

And here's the heat map: trumedia_baseball_grid (25)

Some numbers:

  • Gregorius has gotten three singles off the cutter - two off David Price - and he's batting .375/.375/.375/.750.
  • He's gotten one single off the splitter. .286/.286/.286/.571
  • He has trouble with the changeup, batting .111/.190/.167/.357, but he hit a double in Saturday's game against the Braves.
  • He's hit five singles and a double off the slider and he's batting .259/.259/.296/.556.
  • In six at bats against the knuckleball, he has three singles - two off R.A. Dickey and one off Steven Wright. (.500/.500/.500/1.000)
  • In 67 at bats against the fastball, Gregorius is batting .403/.461/.567/1.028

Since he's having so much success against the fastball, let's take a closer look at that.

As you can see in this heat graph, Gregorius likes the upper part of the strike zone. And while looking at the individual at bat results, I noticed that the majority of his hits on fastballs come within three pitches. There's an occasional four-pitch at bat but most of the hits are occurring on pitches 2 and 3.

Breaking it down further, Gregorius is batting .435/.491/.565/1.056 in 46 at bats against fastballs that fall between 90 and 95 m.p.h. In 12 at bats against fastballs 95 m.p.h and up, he's batting .167/.167/.167/.333.

Narrowing it down again, Gregorius is batting .380/.432/.519/.951 in 79 pitches that are considered hard - fastball, sinker, cutter.

More numbers:

  • With the bases empty he's batting .333/.371/.381/.752/.
  • With men on .317/.357/.508/.865.
  • With a runner on .256/.319/.419/.738.
  • With two on .333/.353/.533/.886.
  • With the bases loaded but in only 8 at bats he's batting .800/.667/1.200/1.867.
  • With runners in scoring position .364/.395/.545/.940.

So what does this all mean? It means that the people who were pooing pooing the move probably feel pretty silly right now. Gregorius is a solid player (.269/.318/.364/.682) who has improved as the season has gone on and he's becoming fun to watch.
