Must-click link: Stephen Strasburg, mechanics and injuries


I tend to glaze over at most stories about pitching mechanics. They seem so jargony. I really have no idea what an “inverted W” is nor do I know why they don’t just call it an “M.”

But today’s story by Tom Verducci in Sports Illustrated is a different thing. It focuses on Stephen Strasburg and his recovery from Tommy John surgery. At the beginning we learn that the Nats are going to try to have Strasburg change his approach. It’s the Crash Davis thing: strikeouts are fascist, so try to get some more ground balls. They’re more democratic.

But then it goes on to explain why Strasburg may have been more likely to need Tommy John surgery than other pitchers. It all has to do with when his arm is fully-cocked and ready to go, and even those of us who aren’t physiologists can understand what Verducci is saying. And, from the sounds of it, what the Nationals aren’t really paying any attention to.

Good article. You’ll learn stuff.

Report: Athletics sign Trevor Cahill to one-year deal

Free agent right-hander Trevor Cahill reportedly has a one-year deal in place with the Athletics, according to’s Jane Lee. The exact terms have yet to be disclosed, and as the agreement is still pending a physical, it has not been formally announced by the club.

Cahill, 30, is coming off of a decent, albeit underwhelming year with the Padres and Royals. He kicked off the 2017 season with a 4-3 record in 11 starts for the Padres, then split his time between the rotation and bullpen after a midseason trade to the Royals. By the end of the year, the righty led the league with 16 wild pitches and had racked up a 4.93 ERA, 4.8 BB/9 and 9.3 SO/9 in 84 innings for the two teams.

The A’s found themselves in desperate need of rotation depth this week after Jharel Cotton announced he’d miss the 2018 season to undergo Tommy John surgery. Right now, the team is considering some combination of Andrew Triggs, Daniel Gossett, Daniel Mengden and Paul Blackburn for the back end of the rotation — a mix that seems unlikely to change in the last two weeks before Opening Day, as Lee points out that Cahill won’t be ready to shoulder a full workload by then. Instead, he’s expected to begin the year in the bullpen and work his way up to a starting role, where the A’s hope he’ll replicate the All-Star numbers he produced with them back in 2010.
