SAN DIEGO (AP) Admitting his San Diego Padres ''didn't have the right formula'' this season, general manager A.J. Preller says he's looking for a manager who can get the underachieving team to play at a high level.

Preller fired interim manager Pat Murphy on Sunday after the Padres finished 74-88 and fourth in the NL West, 18 games behind the division champion Los Angeles Dodgers.

The Padres were a disappointment. Despite the addition of stars such as Matt Kemp, Justin Upton and James Shields and a bump in payroll past the $100 million mark for the first time, the Padres had their worst finish in four years.
