San Diego, CA -- (Sports Network) - David Wells appears ready to return for his 21st season in the majors and second straight in San Diego.

The Padres have reportedly agreed in principle to terms with the veteran lefty on a one-year contract. The San Diego Union Tribune reports Wells will make a guaranteed $3 million in salary for 2007 with a chance for an additional $4 million in incentives. The newspaper reports most of that money is tied to games started.

The 43-year-old Wells was acquired by the Padres this past August 31 from Boston. He made a total of 13 starts in 2006, going 3-5 with a 4.42 ERA. Wells' time on the field was limited with three stints on the disabled list, all related to his right knee.

Wells made 31 starts for San Diego in 2004, finishing 12-8 with a 3.73 ERA. That year he fanned 101 batters compared to 20 walks in his lone full season in the National League.

A three-time All-Star, Wells has a career record of 229-148 with 13 saves and a 4.07 ERA in 630 games. He ranks sixth among active pitchers in wins, third among left-handers, having also thrown for Toronto, Detroit, Cincinnati, Baltimore, the New York Yankees and Chicago White Sox.

When the deal is finalized, Wells will join a rotation that includes Jake Peavy, Greg Maddux, Chris Young and Clay Hensley.
