While the Boston Red Sox were falling apart in September, their Triple A team was surging to the International League championship.

The Red Sox noticed, and on Tuesday promoted Pawtucket manager Arnie Beyeler to become their first base coach.

Beyeler, 48, has spent the last nine years in the Boston minor league system. He previously had spent four seasons in the Texas chain.

He never reached the major leagues as a player, ascending to Triple A in the Detroit system.

By promoting Beyeler and retaining bullpen coach Gary Tuck, the Red Sox have filled their entire coaching staff with the exception of hitting coach. Five candidates have been interviewed.

Either one or two men will be hired to work with the hitters. A decision is expected soon.
