The big news in baseball Monday revolved around the partially torn ulnar collateral ligament in Matt Harvey’s right arm.

Such elbow injuries remain a source of immense frustration within the sport; one scout texted me on Monday saying “we have no more a handle on this than we did 15 years ago.” But if Harvey requires Tommy John surgery he can at least take comfort knowing the recovery rate is quite good.

Concussions represent a different kind of problem — a growing problem judging from statistics compiled by Major League Baseball. Teams have used the disabled list 18 times this season for reasons related to concussions or head injuries an increase from 13 in 2012 and 11 in ’11 the year that baseball introduced the seven-day concussion DL.

Catchers are at particular risk representing 10 of the 18 DL moves (including two for the Red Sox’s David Ross and one for the Astros’ Max Stassi who actually was injured while batting). Six catchers currently are on the DL with concussions — Stassi the Tigers’ Alex Avila the Astros’ Carlos Corporan the Athletics’ John Jaso the Twins’ Joe Mauer and the Rockies’ Yorvit Torrealba.

The good news is that baseball like other sports has made significant advances in diagnosing and treating concussions. The next step is to figure out better preventive measures and people within the game are talking about that too.

Avila will wear a heavier more padded mask when he returns and Tigers general manager Dave Dombrowski says other catchers should consider doing the same.

Catchers from previous generations surely endured concussions; FOX’s Tim McCarver often has said that he has no idea how many he suffered during his 21-year career.
