The Nats had signed Estes, 37, to a $600K minor league deal on February 6th.  Estes tossed one spring inning for the Nats.  In June, Estes said he'd retired from Triple A but not from baseball.  He posted a 3.07 ERA, 4.9 K/9, and 3.3 BB/9 in 73.3 minor league innings for the Dodgers' affiliate.

The Nationals added Guardado in late December.  The 39-year-old had considered retirement, but decided his knee could handle the rigors of another season.  Guardado had this to say to Ladson after he signed: "The Nationals came at me like they really wanted me."  Instead, Everyday Eddie was given only two innings to prove his worth (during which he allowed seven hits).  Last year for the Rangers he posted a 4.46 ERA, 4.7 K/9, and 3.5 BB/9 in 38.3 innings.  Guardado rejoins a list of free agent lefty relievers that includes Joe Beimel, Alan Embree, Ron Mahay, Glendon Rusch, and Jamie Walker.

Estes, 37 later this month, last pitched in the big leagues back in 2008, when he gave the Padres 43.2 innings of 4.74 ERA ball, though his peripherals were ugly (3.9 K/9, 3.7 BB/9). He spent last season with the Dodgers' Triple-A affiliate, posting a 3.07 ERA in 13 starts despite similar peripherals. On the bright side, he did hold lefties to a .206 batting average.

He was tiring of the minor league lifestyle and decided not to pitch in Triple A anymore. All the major league teams received an e-mail explaining that any interested club should contact Ned Colletti and the Dodgers, who say they won't ask for a significant return. 

1:46pm: Diamond Leung reports that Shawn Estes has retired. The 36-year-old was pitching for the Dodgers in Triple A, where he started the season 3-4 with a 3.07 ERA. The lefty accepted the minor league assignment in hopes of fortifying the Dodgers' pitching later in the year.

Bard is interesting – he will be 31 in March, and was injured for much of ’08.  In ’07 he hit pretty well away from PETCO.

FROM 12-4-07 at 3:17pm:

ESPN has a huge team at the Meetings; here are some tidbits that haven’t appeared elsewhere on MLBTR.

• Enrique Rojas says the Royals have interest in Sammy Sosa.  Could that indicate a Mark Teahen trade is in the works also?  Teahen is expected to move to first base to accomodate Jose Guillen, which would push Billy Butler to DH.  But Sammy can only DH.
• Buster Olney says the Rangers and Padres are in on Mark Prior.
• The Padres also like lefties Glendon Rusch and Shawn Estes, and may sign both after the Rule 5 as a means of adding starting depth.
• Jayson Stark says the Mariners made an offer to Hiroki Kuroda in the range of four years, $45MM.
• Jerry Crasnick says Anthony Reyes is generating a lot of interest.  The Cards, by the way, are open to trading Rick Ankiel, Chris Duncan, or Jim Edmonds.
• The Rockies have gotten in touch with Marcus Giles’ agent.
• The Astros aren’t interested in Jon Lieber, despite previous reports.  They liked Matt Clement a bit among the injury guys but are over him now.
• Ryan Howard’s agent and the Phillies will sit down soon to talk about a long-term deal.
