The Los Angeles Angels are expected to have a new manager or general manager by the start of next season, FoxSports.com is reporting.

According to the report, ongoing philosophical differences between manager Mike Scioscia and GM Jerry Dipoto are likely to lead to owner Arte Moreno replacing one or both men.

The report states Scioscia and Dipoto have a strained relationship due to Scioscia's involvement in personnel matters. Dipoto expected autonomy when he was hired in October 2011, FoxSports.com reported, citing unnamed sources.

Ranking seventh in baseball with a payroll under $141 million at the start of the season, the Angels are on pace to finish with their worst record in Scioscia's 14 years. Scioscia, a two-time AL Manager of the Year who guided the Angels to the 2002 World Series title, is under contract through 2018.

The Angels, who had World Series expectations entering the season after adding Josh Hamilton to a lineup that already included Albert Pujols, are in fourth place in the American League West with a 56-71 record.
