On Monday, the Red Sox signed third baseman Adrian Beltre, who spent the past five seasons in Seattle. Now they may be sending another corner infielder the Mariners' way.
The Mariners are expected to receive first baseman Casey Kotchman from the Red Sox in exchange for a major league role player, as well cash and possibly a minor leaguer.
According to the Globe's Nick Cafardo, the role player will be versatile veteran Bill Hall.
Hall, 30, is a lifetime .251 hitter with 104 home runs in eight seasons. In 2006, he hit 35 home runs for the Brewers.
The Beltre signing -- which will become official after he passes a physical, which he will take in Boston Thursday -- made Kotchman expendable, with Kevin Youkilis starting at first base instead of third.
Kotchman, 26, was acquired from the Braves at the July 31 trading deadline in exchange for Adam LaRoche. He hit .218 with one home run and seven runs batted in 95 plate appearances and 39 games with the Red Sox.
Kotchman, a smooth fielder, batted .268 with seven home runs and 48 RBIs between Boston and Seattle last season. He is a .269 lifetime hitter.
