Mariners deal Baek to Padres

Seattle lands righty Wells in exchange for struggling pitcher

SEATTLE -- The Mariners on Tuesday worked out a trade that would send Cha Seung Baek to the Padres for Jared Wells in an exchange of right-handed pitchers.

The Mariners, who designated Baek for assignment on May 21, had 10 days to trade, release, option or assign Baek outright to the Minor Leagues.

Wells, a 6-foot-4, 200-pounder, will join the Triple-A Tacoma Rainiers.

Wells made his Major League debut with the Padres on Sunday, pitching two innings in relief. He allowed two runs in the 11th inning, but rebounded to toss a scoreless 12th -- retiring Ken Griffey Jr., Brandon Phillips and Ryan Freel -- in the Padres' 12-9 walk-off win over the Reds in 18 innings.

Wells appeared in two games for the Padres, surrendering two earned runs in 3 2/3 innings.

Wells, who signed with San Diego as a 31st-round selection in the 2002 First-Year Player Draft, was promoted from Triple-A Portland, where he was 1-1 with a 5.85 ERA and nine saves for the Beavers.

Wells was a initially a starter, but he was shifted to the bullpen last year.

Wells was a member of Team USA that participated in the World Cup in Holland in 2005. He made two starts and went 2-0 with a 1.64 ERA, striking out 13.

Baek, who turns 29 on Thursday, was signed as a non-drafted free agent in 1998 out of South Korea and re-signed as a Minor League free agent on Feb. 3, 2006. He was out of options, meaning he had to pass waivers in order to be sent to the Minors this season.

He appeared in 10 games for the Mariners this season, posting an 0-1 record and a 5.40 ERA, walking 13 and striking out 15 in 30 innings.
