The Adam Dunn situation?

I have Adam Dunn in a few leagues and one in particular I was really relying on his power hitter abilities, luckily since since slump I stole Prince Fielder for next to nothing, R.A. Dickey and Lowe, but with players like Carl Crawford and and Jason Heyward not batting spectacularly I really need some offense, a good portion of my offensive stats for this week belong to Alex Avila, should I attempt to trade Dunn or should I hold on to him and wait for him to start producing again, since we was producing until his appendectomy batting .286 with 3 runs 1 HR and 5 RBI
