We previously dealt with starting pitchers sharing the same last name, but friend of the VORG Isaac Sasson, as well as ESPN’s Jayson Stark asked me a variation of that:
Travis Wood just beat Alex Wood. @jaysonst @dianagram is this a first of some sort?

It’s not a first. But still waiting for our name-game expert, @dianagram to tell us the last time it happened! https://t.co/VoYniiV8vn

It turns out there have been 110 instances of the winning and losing pitcher sharing the same last name through 2015. This includes Fausto Carmona, aka Roberto Hernandez, as well as the Niekro brothers on more than one occasion and the Benes brothers:
