BOSTON (AP) _ Right-hander Pat Rapp agreed Monday to a one-year contract with Boston, giving the Red Sox a projected starting rotation of five former National Leaguers.

Rapp, 31, spent 4 1/2 seasons with Florida and went 12-13 with Kansas City last season. He became a free agent after the Royals failed to offer him a contract by the Dec. 20 deadline.

After going 12-13 with a 5.30 ERA in a career-high 188 1-3 innings last season, Rapp figures to join Pedro Martinez, Tim Wakefield, Bret Saberhagen and Mark Portugal in the rotation. All five had at least 10 wins last season.

Rapp said he had been ``pretty free from injury. I've been somewhat solid. I've pretty much never played on a winning team, except the year Florida won the World Series (1997) and I was traded midway through that.''

Rapp started his major league career with San Francisco in 1992. Florida made him the 10th player chosen overall in that year's expansion draft. He has a career record of 50-60 with a 4.52 ERA.

As part of the deal, the Red Sox have a team option for 2000.
