Yeah, Wrecker.
Probably also rather convincingly. They've faced off a couple of times in the past and Wrecker pretty much always had the upper hand. Wrecker is at that sweet spot, where he is above people like Thing and below people like Thor. When he has his full Wrecking Crew, he becomes much more of a threat.
As far as I recall there was one instance, where Thing clearly got the better of Wrecker. He dodged an attack, grabbed Wrecker from behind and started easily choking him, until he was stopped. So he seems to be strong enough to put the Wrecker into a dangerous chokehold, but as soon as punching, durability and especially the crowbar get involved, he is at a massive disadvantage.
