BOSTON (AP) _ The Boston Red Sox declined Tuesday to exercise their 1998 options on pitchers Bret Saberhagen and Jim Corsi, making them eligible for free agency.

Saberhagen, a two-time Cy Young Award winner, missed all of the 1996 season because of shoulder surgery. The Red Sox signed him to an incentive-filled contract following Roger Clemens' departure for Toronto.

Saberhagen's original goal was to return to action by mid-summer. He finally got back to the majors in late August and made six starts for the Red Sox, going 0-1 with a 6.58 ERA in 26 innings. The option was for $600,000 matching his 1997 earnings.

Corsi, who went 5-3 with a 3.43 ERA in 52 relief appearances, had given the Red Sox an option at $500,000.

Boston is in re-signing both, but at lower salaries. They may file for free agency through Nov. 10.

Shane Mack did file for free agency Tuesday. The outfielder earned $1.85 million last season but had just 130 at-bats as the Red Sox discovered his throwing arm was weak.

Also Tuesday, the Red Sox signed Triple-A pitcher Brian Shouse, who had been in the Baltimore organization.
