It's an injury associated with soccer, and the break-and-stop maneuver on the basepath is a lot like what soccer players do for a living, but their ACLs blow after they do it hundreds and hundreds of times in a row. Hard to say whether it happens if he's under the care of Mets trainers. Anecdotally, I think of blown ACLs as more common in amateur soccer than the pros, so maybe, but what do I know? But it's certainly not crazy to think that more rest over the winter would have made this less likely to happen in spring. The Athletic just ran a piece 5 days ago about the ALC "crisis" in the Premier League. TL;DR it's maybe not as crisis-y as it seems, but there's A LOT of good discussion and guesswork as to the why, including heavy schedule of games, not enough injury preventative training, ramping up training to start a season, tearing the ACL while nursing another injury, type of playing surface, shoes, even genetics. So who the hell knows, it still sucks for Ronny any way you look at it. https://theathletic.com/5120100/2023/12/08/acl-crisis-premier-league-wsl/https://theathletic.com/5120100/2023/12/08/acl-crisis-premier-league-wsl/ One interesting thing was this: In the USA, where Kaeding is based, he says 80 per cent of ACL injuries occur in five sports: soccer (football), American football, basketball, rugby and lacrosse. The common denominator between all these says Kaeding is that they are “an aggressive, competitive, cutting sport activity” (cutting meaning an abrupt change of direction). Mauricio hitting the breaks on the base paths was definitely an abrupt change of direction for his poor knee.
