Giants reliever Brian Wilson will have season-ending Tommy John surgery, although he is seeking a second opinion from Dr. James Andrews. Wilson acknowledged he will have the surgery for the second time.

So who closes for the Giants? Manager Bruce Bochy has said he will use a committee. On Saturday nighy, Bochy used Santiago Casilla in a tie game in the eighth inning. He pitched into the ninth inning and got the first two outs before Javier Lopez was brought in to face a lefthander.

Sergio Romo has the best skill set. He pitched in 65 games last season and pitched 48 innings. He had a 13.13 K/9, 0.94 BB/9, 1.50 ERA and 1.00 WHIP. The fastball averages 88 miles per hour and he relies on a wicked slider, which he mainly throws. The problem is he has had elbow issues and spent time on the disabled list in 2009 and last season.

When Wilson missed time last year, Casilla picked up six saves, while Romo had one. Casilla throws harder and had a 7.84 K/9, 4.35 BB/9, 1.74 ERA and a 1.12 WHIP last season with a 51 percent groundball rate.

Lopez and Jeremy Affeldt could also be called upon to get a lefthander out.

I'd add Casilla and Romo in that order. In the NFBC with a $1,000 FAAB budget for the season, I won Casilla for $237.
