Erik Bedard, the talented but often-injured left-hander who might have drawn interest at the trading deadline next week, has once again landed on the Seattle Mariners disabled list.
Bedard's left shoulder inflammation, which limited him to four starts since June 6, is a puzzle to the pitcher and his team.
"We just don't know what it is and neither does Erik, but we have to find out," manager Don Wakamatsu said. "Erik will thrown a bullpen in about four days, after getting treatment to calm down the inflammation, and hopefully we'll know more then."
Bedard went on the DL for the second time this season after throwing 81 pitches in a loss Saturday, making room for today's starting pitcher, lefty Jason Vargas, who was recalled from Tacoma.
The latest injury virtually assures that Bedard will not be traded before or at the July 31 deadline. He and third baseman Adrian Beltre - both potential free agents after the season - will be on the shelf as the deadline expires.
When healthy, Bedard has made 15 starts this season, going 5-3 with a 2.82 earned run average. A year ago, after being acquired in a trade that sent Adam Jones, George Sherrill and prospects to Baltimore, Bedard wnt 6-4 with a 3.67 ERA in 15 starts and didn't pitch after July 4.
"Erik wants to compete but knows he can't compete the way his shoulder feels now," Wakamatsu said.
