I doubt it, he has 0 IP.
In all seriousness I think it's possible. He is on pace for around 170 and he, like all other players, will wear down toward year's end. Psychology might play a role as well considering when a team is not doing well and is about to miss the playoffs players tend to overswing because they feel they need to swing for the fences everyday. Being a young player I think this will also get the best of Howard.
That being said, with those types of stats I wouldn't mind him on my team even if he did "achieve" that.
