What a rollercoaster ride Angel Cabrera has been on.The 2009 Masters champion has gone from an Argentine prison to back-to-back winner on the PGA Tour Champions circuit. He capped off another incredible week on Sunday, winning the Senior PGA Championship by one stroke ahead of Padraig Harrington and Thomas Bjorn.He signed for a 3-under 69 at Congressional to fend off a host of challengers, finishing at 8-under overall.Incredibly, this is Cabrera's second major title in less than a week. The 55-year-old captured the rain-delayed Regions Tradition on Monday in Alabama.That was the first Senior major title of his career. Six days later he doubled that feat.For much of the final round, the tournament was wide open. Several players either held the lead or were within a shot of it.But Harrington's costly double bogey on 15 loomed large. Meanwhile, Cabrera, playing a couple of groups later, birdied the same hole. That proved to be the difference.Cabrera's success is so unlikely considering what he has been through the last few years.Angel Cabrera was sentenced to prison in his home nation of Argentina for domestic violence, among other charges. He spent nearly 30 months in jail, both in Brazil and Argentina, before being released in late 2023.The 2007 U.S. Open champion was welcomed with open arms by the Tour, even earning his place back at Augusta National to play the Masters. That decision was not well received by everyone, particularly activist groups.Nevertheless, Cabrera has found his home once again, dominating on the golf course.More Golf: Colonial Leader Having Breakthrough, Warns PGA Tour 'More to Come
