Ugh, that dreaded headfirst slide. It can sneak a player in under a tag but it can also do what we saw it do to Angels OF Mike Trout today...lead to a thumb injury. X-rays were reported as negative but the extent of soft tissue damage will dictate his absence. Typically, a thumb getting pulled away from the rest of the hand when it hits the bag results in damage to the ulnar collateral ligament (of the thumb) but the exact angle and force of impact will determine what structures are injured and how severely. That in turn dictates treatment; the most minor sprain could resolve within days, a complete ligament tear could mean surgery. Further imaging will yield more information but until then fans have to hope this was more of a scare than anything else.
