A's trim roster, part ways with Bonser, James

A's trim roster, part ways with Bonser, James

OAKLAND -- The A's cropped their 40-man roster yet again Tuesday, this time eliminating relief pitchers Boof Bonser and Justin James, along with outfielder Matt Carson.

Bonser and Carson were outrighted to Triple-A Sacramento -- the former electing free agency and the latter agreeing to terms on a 2011 contract with a non-roster invitation to Spring Training. James, meanwhile, was claimed off waivers by the Milwaukee Brewers.

The A's now have 30 listed on their 40-man roster. That number does not include Ryan Sweeney, Conor Jackson, Adam Rosales, Josh Outman and Joey Devine -- all of whom are currently on the 60-day disabled list but could return next year.

Bonser split his 2010 season with the Red Sox and A's, who signed him to a Minor League contract on July 3 after being designated for assignment by Boston a couple of weeks prior. He was 1-0 with a 5.09 ERA in 13 relief appearances with Oakland but was not expected to return in 2011 with several other bullpen options already intact.

Carson is no stranger to Sacramento, where he was shuffled back and forth between four stints in Oakland this year. He proved his power worth with the River Cats, batting .303 with 13 home runs and 36 RBIs in 64 games, but struggled with consistency in the big leagues, finishing the year with a .177 mark and four home runs in 36 games.

The 29-year-old Carson received most of his playing time in right field and has provided the A's with a strong backup outfield option. However, the club is set on adding power this offseason, an asset which may very well come in the form of an outfielder. The A's also expect right fielder Sweeney, who underwent knee surgery in July, to be healthy by spring. Nevertheless, Carson will likely begin yet another season with Sacramento.

James, a hard-throwing September callup, offered the A's a feel-good story toward the end of the 2010 campaign. His year began with the Kansas City T-Bones in the Independent League and ended in Oakland, where he posted a 4.50 ERA in five relief appearances for the A's. He was immediately added to Milwaukee's 40-man roster.
