I’ve linked to this spreadsheet before which keeps a running list of pitchers who have undergone TJS and associated statistics.
If you want to see average recovery times broken down by say the age of the pitcher when the surgery was performed (15.6 months for someone Verlander’s age) or by time of year when the surgery was performed (19.3 months for Jul-Sep surgeries) you can see that here:
Jake Kaplan has an update on Austin Pruitt today. Pruitt (Luhnow’s final acquisition, from the Rays) had surgery four months ago to put a screw in his elbow to fix a hairline fracture. He was cleared to begin throwing on Monday, but he is quarantining after a positive COVID test. He is not expected to be done with his rehab by Opening Day, but will hopefully be throwing off a mound during spring training.
According to the MLB operations manual, a person who has been identified as having been in close contact with a confirmed case of COVID will be subject to a mandatory quarantine of seven days and must test negative on Day 5 or later among other requirements to rejoin facilities. Individuals who test positive will be required to isolate for a minimum of 10 days and must be cleared by physicians.
Regardless, the eight pitchers won’t be working out with their teammates at Ballpark of the Palm Beaches or appearing in Grapefruit League games for at least the next week. Martes and Paredes each threw an inning in relief in Houston’s win over St. Louis on Thursday night.
Neither Alvarez nor Bregman has appeared in a game yet this spring. Earlier this week, Baker said Bregman was ahead of Alvarez in his return to play, but changed his tone Tuesday after speaking with the Astros’ athletic trainers. Baker said Alvarez, who underwent surgery on both knees last August, could debut in a game early next week and Bregman would follow “shortly after that.”
