Boston Hosts Baltimore

Tonight's start features Garrett Olson vs Bartolo Colon.

We previewed Olson 12 days ago here.

Here is his pitch types:



Colon throws 4 pitches. A two seam fastball, a four seam fastball, a slider and an occasional changeup. Here is his pitches using K-Means Cluster:


Same type of graph as we used for Olson. Colon is right handed, Olson is left handed so that is why they look opposite. These graphs are horizontal vs vertical movement and seen from the catcher's view.

The red is his four seamer, the orange is the two seamer, the green is the slider and the blue is the changeup.

None of his pitches stand out. He really is a shell of himself from his Cy Young days. A big shell at that. Fat jokes aside, he has given the Red Sox some nice starts at the back end of the rotation. While his stuff isn't what it used to be, he is keeping the ball down and showing decent control. His HR/9 rate is less than half of his career average currently and his ground ball percentage is the highest of his career at 43.6. Expect the Sox to cut bait as soon as they see him struggle as we head to the summer.
