The Houston Astros added valuable RHP Kendall Graveman to their bullpen in a controversial trade with the Seattle Mariners on Tuesday, a move that on the surface seems a bit perplexing and frustrating for fantasy baseball managers. Why would the Mariners, peripherally contending in the AL West, trade their top relief pitcher to a division rival? Well, that one is easy. Graveman is a pending free agent and the Mariners picked up enticing young third baseman Abraham Toro in return. Relief pitching is volatile. Go for it.
