I read from the papers yesterday that there will be a Corrales vs. Castillo part 3. Castillo won the 2nd fight by knocking Corrales on the 4th but didn't get the title because he was a bit overweight, hence the rematch. Also, Corrales is saying that he lost because of that.
Also, Pacquiao will have a match in July vs. Larios here in the Phils. I think it's just a warm up match before his 3rd fight with Morales late this year.
