In a record spree that sent shock waves through baseball — and could dramatically alter the Southern California sports scene — the Angels on Thursday announced they had spent $331 million to acquire baseball's most feared slugger and one of its top left-handed pitchers.

Within a span of two frenzied early-morning hours, the Angels reached agreements with first baseman Albert Pujols for 10 years and $254 million and C.J. Wilson for five years and $77.5 million.

Pujols' deal is the second-largest in major league history. And it gives the Angels the kind of star power to challenge the Dodgers, who are struggling on and off the field, as the region's premier baseball franchise.
