Power-hitting outfielder Carlos Quentin and the Padres are on the verge of completing a extension which will keep him in San Diego and take him off the trade block, people familiar with the talks told CBSSports.com.

The deal is believed to be worth about $27 million over three years and includes a very reachable bonus that could bring the total to $30 million.

The Padres' move to sign Quentin is something of a surprise, as he was seen as a prime trade candidate this month. The signing is a big step for the Padres, a low-revenue team that's long been unable to sign stars to multiyear deals due to finances.
