Team just drafted...needs serious help

[avk_7_7]

12 teams roto, cats: R HR RBI SB TB AVG OBP
W K SV ERA WHIP
I missed the draft and ended up without a single closer. Who should I try to deal for a closer, and should I keep Bonds for his OBP? League doesn't start till 17th, so I should have cantu, prior, and burnett back. Otherwise, is the team solid?
