Who will be the Sox closer now?

Now what?

In the wake of Tuesday’s surprising trade that sent Sergio Santos to the Blue Jays for minor-league starter Nestor Molina, the White Sox have to scramble and find a new closer.

At the winter meetings in Dallas Tuesday, general manager Kenny Williams told reporters he moved Santos because the Sox are deep in the bullpen.

Williams rattled off a long list of potential in-house closers — Matt Thornton, Jesse Crain, Addison Reed, Jhan Marinez (acquired from the Marlins for Ozzie Guillen), Josh Stewart, even minor-leaguers Brian Omogrosso and Gregory Infante.

“Fortunately for us, it is an area where we have a lot of depth,” Williams said. “We thought we could afford to do this and take care of our future a little without sacrificing our present.”

Thornton opened last season as the White Sox’ closer but was replaced by Santos after blowing four straight save opportunities in April.

Crain is an established veteran, but he blew 6 of 7 save tries. Like Thornton, he is better suited for a setup role.

That might leave Reed as the best option.

The 23-year-old right-hander barreled through the minor-league system last season, going a combined 2-1 with a 1.26 ERA and 5 saves in stops at Class A Kannapolis and Winston-Salem, AA Birmingham and AAA Charlotte.

Reed joined the Sox in September and allowed 3 earned runs in 7⅓ innings while striking out 12.

“At this point, you’re going in and getting it from within,” manager Robin Ventura told reporters Tuesday when asked about the new closer. “So you’re looking at some young kids that will be able to have a shot to do it and try and make it work. You feel like you have the talent there to do it and fill that slot.”

Buehrle watch:Yes, manager Robin Ventura talked to Mark Buehrle in New York earlier in the off-season, and general manager Kenny Williams spoke with the free-agent starting pitcher last week.As for Buehrle returning to the White Sox, the odds remain incredibly long.The Mets on Tuesday reportedly joined the Nationals, Marlins and Rangers in the Buehrle sweepstakes.#147;I hear he#146;s a very popular man and he#146;s going to be richer than he is,#148; Williams said when asked about Buehrle Tuesday. #147;Mark and I had a good conversation last week in which I expressed to him once again how much he is valued in Chicago. At this point, it#146;s strictly finances over a desire not to have a deal.#147;Who wouldn#146;t want this guy? Two hundred innings you can put in the book, 200 good innings. A lot of guys can pitch 200 innings. So many peripheral things, it doesn#146;t even need to be mentioned. On the bus, off the bus, on the plane, off the plane, on the field, off the field. (Heck), we don#146;t know who#146;ll catch the (ceremonial) first pitch anymore.#147;He#146;ll be missed unless something happens that#146;s unforeseen right now.#148;Moving forward:General manager Kenny Williams said he might be done making moves because he does not like the offers he#146;s received for some unnamed White Sox pitchers, presumably John Danks and Gavin Floyd.With a guaranteed contract worth $13 million for the next two years, relief pitcher Matt Thornton would likely be moved for next to nothing in return.Williams did say the situation is subject to change in a hurry.#147;I don#146;t want to mislead you guys in saying that anything is definitive,#148; Williams said. #147;We still have some interest in some of our position players and we#146;re going to listen. There are a couple of things we have to do payroll wise, but unless we get back what we need to continue the rebuilding process, we#146;ll just go into this season looking to compete at the same time as rebuild.#148;
