BA’s longtime Padres correspondent, John Maffei of the North County Times, reports the club won’t be able to sign its de facto backup first-round pick despite offering him first-round money.

Buhach Colony High’s (Atwater, Calif.) Brett Mooneyham—the top prep lefthander on several draft boards, a Scott Boras Corporation client and a Stanford signee—turned down a reported $1.4 million, the same amount the Padres offered to first-rounder Allan Dykstra before the deal fell apart over concerns about Dykstra’s hip. Mooneyham is pitching in an American Legion regional tournament in Montana this week and has shown his usual electric stuff, with a fastball in the low 90s, but he was expected to be one of the draft’s toughest signs and has turned out to be just that.

San Diego also will miss on Arizona State outfielder Jason Kipnis (fourth round) and Texas A&M righthander Kyle Thebeau (ninth), both of whom will return to college. The Padres are expected to announce the signing of South Carolina third baseman James Darnell (second) shortly.
