Yasuo will make Yorick's life hell pre-6, and, if properly fed or the Yorick gets a little too cocky, will make his life hell post-6. Yorick's minions are easy targets for dashing, Yasuo can dash out of the wall if a target is close enough to do so, and windwall will block Yorick's E so no getting marked and jumped on by the ghouls and the Maiden. Of course, the maiden is a huge source of damage and is not blockable by windwall, and Yorick's Q+Sheen still chunks like no tomorrow, but most Yasuos probably wouldn't even let him get close if the Maiden targets him.
Swain outsustains Yorick in trades, especially post-6.
Renekton has two dashes and his godly early game damage and sustain.
Rumble clears minion waves (Aka: pets as well) well enough, and engaging on Rumble means taking Flamespitter to the face.
Mobile ranged tops like Vayne, Quinn, Graves, Kennen, will kite him to hell and back.
Ignite and Exec's calling can null the sustain given to him from Q, Ghouls, and Maiden. Hexdrinker would control the damage dealt from the Maiden and Passive max health % magic damage from Yorick attacking the same target as her.
