The Associated Press reported Friday night that the Mariners are nearing a four-year deal with free-agent pitcher Jarrod Washburn.
The deal is worth between $35 and 40 million, a person familiar with the negotiations told The AP, speaking on condition of anonymity because the deal was not yet in place.
Seattle general manager Bill Bavasi could not be reached for comment.
The News Tribune of Tacoma first reported the parties nearing an agreement on its Web site.
After spending his first seven years with the Angels, Washburn became a free agent on Dec. 7 after the Angels declined arbitration for the 31-year-old left-hander. He was fourth in the American League with a 3.20 ERA last season.
Last year, Washburn went 8-8 and made 29 starts. He had a brief stint on the disabled list with inflammation in his pitching elbow. It was just the sixth time in his career he was on the disabled list.
His best season came in 2002, when he went 18-6 with a 3.15 ERA and helped the Angels to a World Series title.
