"With each passing day, each line drive to left, each six-run game, it becomes harder to assign the performance of those teams to their cheating. The Astros’ numbers can’t just be a product of TV monitors and trash cans, not when in the absence of those they’re even better."

"It’s notable that the Diamondbacks are 5-37 in their last 42 games, which encompasses the current 23-game road losing streak, but they haven’t played quite that poorly. The 1-11 mark in one-run games during that stretch is making them look worse than they are. They’re a true-talent 78-win team that's had its lack of depth exposed with an enormous number of pitching injuries all at once."

Joe Sheehan Newsletter, "Tyler Glasnow"

As you have probably heard, Rays right-hander Tyler Glasnow has a partially torn right ulnar collateral ligament and a flexor tender strain in the same arm. There’s no determination yet as to whether Glasnow will have Tommy John surgery, and because of where we are on the calendar, he has the flexibility to wait to see if therapy will help. Surgery now or surgery in two months both leave him losing most or all of the 2022 season.

This is a blow to Glasnow, who since being traded to the Rays in 2018 has a 3.10 ERA in 48 starts. Glasnow has a 2.66 ERA with a 36% strikeout rate so far this year in 14 starts. He’s established himself as having the skill set of a #1 starter, with the question being whether he could hold up in the role. Glasnow, now in his sixth year in the league, has never thrown more than 111 innings in an MLB season.

In his newsletter, Will Carroll laid out one potential plan Glasnow and the Rays could implement:

“I am told the Rays are exploring the idea of repair, but are reluctant to be one of the first elite level athletes to do so. It has been done in high level college and at least once in MLB (Seth Maness), but the InternalBrace technique is still new and surgeons are very picky about who qualifies for this. With Dr. James Andrews as medical director and his partner Dr. Jeff Dugas one of the leaders in this kind of repair, it’s a possibility. A repair would significantly cut down on healing time, though at nine months for the single admitted case, it shouldn’t be that significant over what should be a year, though others have come back in a much shorter time.”


The Rays were counting on Glasnow after a winter in which they let Charlie Morton leave and traded away Blake Snell -- both moves that have looked pretty good so far. The Rays continually integrate exciting young starters, like Rich Hi...I mean, like Shane McClanahan, and we will probably see Shane Baz before long. None of these pitchers, though, bring the potential for seven shutout innings to the mound every night the way Glasnow does. This injury, if it does lead to surgery, closes the gap between the Rays and the three teams chasing them in the AL East, probably by two wins.

I hate that I have to circle back to this again, but Glasnow becomes the latest starting pitcher to blow out while pushing the upper bounds of velocity. Since he became a full-time starter in 2019, Glasnow has averaged 96.2 mph with his four-seam fastball, and was at 97 mph in his 80 innings this year. The following chart will be all too familiar to long-time readers. I have lowered the innings threshold to 300 to include Glasnow, who has 403 career innings in total, but just 335 as a starter.

Mind you, the 300 innings threshold leaves off an awful lot of names. If we just look at the hardest-throwing starting pitchers in a given season...

Stephen Strasburg   2010    97.3     2010
Zack Wheeler        2021    97.2     2015


That’s a long list. If I keep going, it’s more Nathan Eovaldi and Noah Syndergaard seasons. Dinelson Lamet’s name comes up. Glasnow. Yordano Ventura, who had elbow issues prior to his untimely death. James Paxton. Shohei Ohtani in 2018. (Ryne Stanek’s presence here is misleading, as he was a reliever being used to start games as an opener, rather than someone carrying a starter’s workload.)

Fastball velocity is a proxy for something we can’t measure, the stress placed on the ulnar collateral ligament by the act of pitching. What is clear, though, is that no starting pitcher lasts very long pushing the bounds of velocity. Some, having had their UCL repaired, seem to be able to survive throwing this hard -- deGrom is the best current example (for the moment), having had the surgery in 2010 just as his pro career was getting underway. Eovaldi, Walker Buehler, and Zack Wheeler are similar cases.

We select pitchers for velocity at almost every level, and given the caliber of hitters in today’s game, asking pitchers to go at much less than 100% is a recipe for runs. The hardest-throwing starters in baseball almost all get hurt, though, with Tyler Glasnow just the latest example. It’s awful, as a fan, to keep seeing these bright young stars have years carved out of their career. I don’t know what the answer is; I just know that the relationship between maximum velocity and a date with a surgeon is too strong to ignore.

"It’s just not clear what Scherzer would bring back in trade. You can draw a line at 2016, when the Cubs, trying to win a World Series for the first time since 2018, sent a very highly regarded prospect in Gleyber Torres to the Yankees in order to rent Aroldis Chapman for a few months. That trade helped contribute to a hell of a party, but it, and in fact that whole trade season, sticks out in the modern game. It’s now incredibly difficult both to get teams to trade top prospects and for teams to get much value for rentals."

"Prior to the 2021 season, MLB announced that it was making the baseball lighter and lowering its coefficient of restitution. Very quickly, it was apparent that the new ball had higher drag that was showing up in the Statcast numbers. The ball was jumping off the bat, producing the highest exit-velocity readings in the measurement era, but not flying as far. The drop in offense we’re seeing this year is wholly explained by the drop in production on contact -- by the new baseball."
