Phil Mickelson has joined a group of investors who want to buy his hometown Major League Baseball team, San Diego Padres. Mickelson said Monday afternoon he is involved with Kevin and Brian O'Malley, and their cousins Peter and Tom Seidler, as one of five groups trying to buy the team. John Moores said last month he is putting the team up for sale. The four-time major champion declined three years ago to get involved in a bid to buy the Padres. Mickelson said this time he sees it as a good investment opportunity. He said his interest is to help strengthen the relationship between the city and its baseball team.
