Chico Harlan's gamer has this:
Olsen's fastball, on this night, registered between 87 and 88 mph. His change-up, normally one of his top pitches, took an adrenaline shot and registered in the low-80s -- too fast for its purpose. As a result, pitching coach Randy St. Claire said, "there wasn't much of a difference. A lot of the change-ups I thought were fastballs."Here's the problem. Last year, according to pitch f/x data at Fangraphs, the average velocity of an Olsen fastball was 87.8 and his change sat at 81.7. His average change on Tuesday was actually down at 81.1. His average fastball was all the way down at 86.9.
Yes, you read that right. Eighty-six point nine miles per hour.
St. Claire is right that 5.9 miles per hour isn't enough of a gap between a fastball and a change-up to fool anyone. But the team should have known that before they traded for him and installed him as the #2 starter. What you saw Tuesday is what Scott Olsen is, sadly.
