Where does Vlad rank among free agents?

Someone asked me the other day if Vladimir Guerrero was the top offensive free agent signing this offseason. You could certainly make that argument.

Guerrero is batting .339 with six homers and 26 RBIs. He even has four stolen bases and his body appears to be holding up just fine so far this season. He's making $5.5 million (the contract includes performance bonuses) this season and there's a mutual option (with a $1 million buyout) for 2011. So who else signed offseason deals that look good so far this season? ESPN Stats & Information put together a list. Here goes (all stats through Sunday):

* Arizona's 2B Kelly Johnson (one year, $2.35M): 10 HRs, 19 RBIs and a .282 batting average. He hit just eight HRs in 303 at-bats last season.

* Toronto SS Alex Gonzalez (one year, $2.75M): He's a defense-first infielder with Toronto who's added 10 HR (he hit eight all of last year) and 27 RBIs.

* Chicago OF Marlon Byrd (three years, $15M): The former Ranger has a .347 BA, 6 HRs, 22 RBIs.

* New York Mets C Rod Barajas (one year, $500K): Another former Ranger, he leads the Mets with nine HRs.

* New York Mets C Henry Blanco (one year,$750K): Backup has thrown out all five baserunners this season in limited action.

* Washington C Pudge Rodriguez (two years, $6M): .365 batting average for the catcher that turned down a one-year offer from the Rangers and got a multiyear deal in Washington.

Here are some who have struggled:

* New York Mets' Jason Bay (four years, $66M): one HR, 12 RBIs, .248 batting average.

* Seattle's Chone Figgins (four years, $36M): He's hitting just .185 for a struggling Mariners lineup.
