Dr. James Andrews explains why Tommy John surgery is on the rise

Dr. James Andrews was on Sirius/XM radio’s “Power Alley” with Mike Ferrin and Jim Duquette¬†yesterday, talking about Tommy John surgery. He was asked why there seem to be so many guys needing TJ surgery these days.

His answer: it’s not an anomaly, it’s a trend. And an alarming one, he says, in that so many more of the surgeries he’s performing are for high school pitchers as opposed to professionals with a few years under their belt. Kids are bigger and stronger these days, and their ability to throw harder is outpacing the development of their ulnar collateral ligaments.

But the biggest risk factor he and his researchers are seeing: year-round baseball. The fact that not only do pitchers throw year-round, but that they are pitching in competition year-round, and don’t have time to recover. Also: young players are playing in more than one league, where pitch count and innings rules aren’t coordinated. Another factor: the radar gun. Young pitchers who throw over 85 or so are at risk, and all of them who are on a major league track are throwing that fast or faster, and are going up in effort when scouts with guns are around.

Ultimately, you can’t prevent these injuries. Even for the major leaguers, most of whom were damaged in high school only to have the UCL injuries happen once they’ve hit the pros.

Give a listen to the TJ expert.

Bad news for the Cubs’ Yu Darvish: The right-hander is headed back to the disabled list with right triceps tendinitis, the team announced Saturday. It’s the second such assignment for Darvish this season, but the first time he’s been sidelined with arm issues. Neither the severity of his injury nor a concrete timeframe for his recovery has been revealed yet, but the move is retroactive to May 23 and will allow him to come off the DL by June 2, assuming all goes well.

Prior to the injury, Darvish went 1-3 in eight starts with a 4.95 ERA, 4.7 BB/9 and 11.0 SO/9 through 40 innings. Needless to say, these aren’t the kind of results the Cubs were hoping to see after inking the righty to a six-year, $126 million contract back in February, though the circumstances affecting his performances appear to have largely been out of his control. He missed a start in early May after coming down with the flu and has struggled to pitch beyond the fifth inning in five of his eight starts to date.

The Cubs recalled left-hander Randy Rosario from Triple-A Iowa in a corresponding move. Rosario has yet to amass more than five career innings in the majors, but has impressed at Triple-A so far this year: he maintained an 0.97 ERA, 2.8 BB/9 and 6.1 SO/9 through 19 1/3 innings in 2018. As for Darvish’s next scheduled turn in the rotation, Tyler Chatwood is lined up to take the mound when the Cubs face off against the Giants in the series finale on Sunday. A starter for Monday night’s game has yet to be determined.
