While the Colorado Rockies are expected to be sellers this summer, outfielders Carlos Gonzalez and Michael Cuddyer are not going to be traded, general manager Dan O’Dowd told Jon Heyman of CBSSports.com.

"The Carlos Gonzalez thing is a joke,'' O'Dowd said. "We're not trading Carlos Gonzalez.''

"I've had a ton of calls on Michael Cuddyer,'' O'Dowd said. "But I'm not trading him, either.''

O’Dowd also said he expects to keep center fielder Dexter Fowler as well as relievers Rafael Betancourt and Matt Belisle. However, the GM wouldn’t call any of the players mentioned above untouchable, and Heyman notes that relievers on losing teams are usually viewed as trade candidates.

Unless Colorado is overwhelmed with an offer, the only players that are likely to be traded at this point are veteran right-hander Jeremy Guthrie, pinch-hitter Jason Giambi and middle infielder Marco Scutaro.

Heyman says the Toronto Blue Jays, who recently lost three starting pitchers to injury, spoke with the Rockies regarding Guthrie, but the sides were unable to work out a deal.

Though it doesn’t look like there will be any major trades taking place this season in Colorado, Heyman adds that O’Dowd has been known "to have a surprise or two up his sleeve."
