Use Number One Waiver Priority for David Ortiz? WHIR

[sman]

I am in a head to head ten team keeper league on Yahoo! which uses these stats R, H, 3B, HR, RBI, SB, AVG, OBP, W, CG, SHO, SV, K, ERA, WHIP, K/BB.

My Roster:

C Miguel Montero
1B Gaby Sanchez
2B Ian Stewart
3B Mark Reynolds
SS Jose Reyes
OF Shin Soo Choo
OF Carlos Gonzalez
OF Ichiro Suzuki
Util Chase Headley
BN Luke Scott
BN Asdrubal Cabrera
DL Justin Morneau
DL Ian Kinsler

SP Roy Halladay
SP Johan Santana
RP Brian Wilson
RP Rafael Soriano
P Francisco Liriano
P Jonathan Sanchez
P Chad Billingsley
BN Jaime Garcia
BN Gio Gonzalez
BN Anibal Sanchez

So, another owner has just dropped David Ortiz in our league and I have the first place waiver priority. Should I use this to pick up Ortiz?

Thanks in advance. Leave a link and I'll get back to you.
