MASH Report: Starting Pitcher DL Chances
One item is always hanging over my head once the season ends, is the final clean disabled list report in which I have published every year since 2010. This morning, I completed finalizing the list and it is now time to run some queries. Most of the general information will be available in my annual article at The Hardball Times later this month or early next month.
For today’s MASH Report, I am going to publish my yearly starting pitcher disabled list chances. For this report, I have always incorporate the following factors.
• Age: The older the pitcher, the more the injury risk (+1% point increase each year older)
• Injury history: Nothing predicts future injuries like past injuries (+10% points for each season of the past three on the DL).
• Games Started: A pitcher needs to show they can throw for an entire season without breaking down (-3% points for each full season up to three).
Every year the average disabled list chance hovers around 40% which works out to two out of every five starters in a rotation will miss some time. Some teams will get hit with more injuries while others less.
