Sources: Blazers, Raptors, Spurs, and Timberwolves emerge as top Gasol suitors

— -- Six-time NBA All-Star Pau Gasol has emerged as the target of a lucrative bidding war in free agency that has at least four teams chasing him, according to league sources.

Sources told ESPN.com on Sunday that Gasol has received significant interest in recent days from the Portland Trail Blazers, Minnesota Timberwolves and Toronto Raptors in addition to the San Antonio Spurs, who are widely expected to be a top contender for Gasol in the event that the Spurs do not win the Kevin Durant Sweepstakes.

The Blazers, sources said, are offering a two-year deal in the $40 million range to try to land Gasol, who spent the last two seasons with the Chicago Bulls.

The Timberwolves, sources say, are offering a similar deal in hopes of convincing Gasol to reunite with former Bulls coach Tom Thibodeau.

It's not immediately clear if Gasol is intent on waiting until after Durant makes his decision to choose his next team or if he'll choose one sooner, but one source close to the process told ESPN.com's Ramona Shelburne that the market for Gasol is landing in the $18 million to $22 million range in terms of annual salary.
