qualls pitched in a non-save situation last night (they were losing) but gave up 1 run. Tony Pena would most likely be the closer, rauch has been used in middle relief which means there is little chance he is the closer if something happens to qualls. pena is the add if your desperate and have room on your roster, but pena has been shaky the past 2 weeks so i wouldn't add him until/if qualls goes on the DL.
the rays BP is a full-blown committee. i know as a fantasy player you don't want to hear that but joe maddon could care less about fantasy baseball. depending on matchups in the 7-8-9 innings maddon could use any of wheeler, howell, nelson, izzy, etc in any type of order to close out a game. stay away from the situation because its just a guessing game...but if MUST add someone, it should be howell. howell has great K numbers and will help you in ERA/whip but he is most likely the furthest guy from closing out games as he is a lefty specialist...although he occasionally does get the save.
