Nationals fans were distraught when the team announced in a press conference Tuesday that Strasburg will be undergoing more surgery. Reportedly, team doctors recently discovered a wisdom arm coming in, and it needs to be removed immediately.
Unlike wisdom teeth, which are frequently extracted for health reasons, a wisdom arm carries virtually no health risk. However, wisdom arms are against MLB's Extra Limb Policy. Rule 4.2 b) under section 7 states "no player shall be allowed to advantageously utilize any extra limb, appendage or member".

Stevenson says rule 4.2 b) was not always in place, but was implemented in 1968 when Willie Stargell showed up to spring training with an extra leg. The big slugger had stolen 47 bases through the first two months of the season before MLB realized it had a problem on its hands.
