In the trade, the Rays acquired pitchers Adam Russell, Cesar Ramos and Brandon Gomes, as well as infielder Cole Figueroa.
The Padres will also receive a player to be named later from Tampa Bay.
It was no secret that the Rays were trying to deal the 31-year-old Bartlett, who is eligible to become a free agent after the 2011 season and was due a raise from the $4 million he received in arbitration a year ago from Tampa.
Bartlett struggled last season, hitting just .254 with four home runs and 47 RBI. His disappointing year was a far cry from a remarkable 2009 campaign that saw him bat .320 with 14 home runs and 66 RBI.
In the right-hander Russell and left-hander Ramos, the Rays get a pair of hurlers who could very well be a part of their 2011 bullpen. Russell appeared in 12 games for the Padres last season and pitched to a 4.02 ERA without recording a decision.
Ramos, a first-round supplemental pick by the Padres in 2005, has worked sparingly in San Diego the past two seasons, appearing in 19 games, two of which have been starts. He is 0-2 with a 6.26 ERA, but has struck out 19 batters in just 23 innings.
Gomes spent all of last season with the Padres Double-A affiliate San Antonio (Texas), while Figueroa has spent three seasons in the Padres’ farm system.
