All indications are the Dodgers are closing in on a possible agreement with veteran left-hander David Wells, who was released last week by San Diego, making him a free agent. Gregg Clifton, Wells’ Phoenix-based agent, said earlier today that, “If it’s going to happen, it will probably be within the next 24-36 hours,” saying Wells didn’t want to negotiate with any club beyond tomorrow. The Dodgers could have Wells for a prorated share of the major-league minimum salary of $380,000 (about $80,000), but in order to lure him out of semi-retirement, they might have to agree to play a complicated performance bonus in Wells’ contract that was nullified when the Padres released him. Wells’ contract called for him to receive an additional $176,471 per start for starts No. 11-27, and he present has 22 starts. That means the deal could cost the Dodgers an additional $882,355. If he signs with the Dodgers, Wells likely would take the rotation spot of Brett Tomko, meaning he would make his Dodgers debut on Sunday night against the New York Mets at Shea Stadium. It isn’t clear whether other clubs are still pursuing Wells, but Clifton said Wells has a strong desire to play for a contending NL West team that plays on the West Coast — a preference that leaves the Dodgers as the only suitors with a legitimate chance of signing him.
