BOSTON (AP) — The Boston Red Sox have parted ways with president of baseball operations Dave Dombrowski less than a year after winning the World Series.

Red Sox spokesman Kevin Gregg made the announcement Sunday night following a 10-5 loss to the New York Yankees that dropped the defending champions 17½ games behind their longtime AL East rivals. Boston, which had won three straight AL East titles, would be eliminated from the division race with a loss in the series finale on Monday night.

A veteran baseball executive who built a World Series champion in Miami and helped the Tigers win two AL pennants, Dombrowski was brought in to steady the Red Sox front office in 2015 with the team in the middle of back-to-back last-place finishes.

The Red Sox followed with three straight AL East titles — a first time in franchise history, winning a club-record 108 games last season and their fourth World Series since 2004.

But this year's team — with largely the same roster as last year's — has gone 76-67, losing five of their first six games and never really getting back into contention in the division. While Dombrowski stood pat at the trade deadline, with a wild-card berth still in reach, the ballclub reeled off an eight-game losing streak.

Gregg said Boston's assistant general managers would share Dombrowski's duties for the final few weeks of the season.
