The A's apparently are willing to trade Blanton without acquiring any of the Dodgers' young major leaguers — a group that includes outfielder Matt Kemp, first baseman James Loney and reliever Jonathon Broxton.
But in return, the A's want at least one young starting pitcher who is close to the majors, and because of that the teams have struggled to find a match.
Class AA left-hander Scott Elbert, considered the Dodgers' top pitching prospect, underwent surgery on his throwing shoulder in June and is expected to miss the rest of the season.
Class A right-hander Clayton Kershaw, the Dodgers' first-round pick in 2006, is another coveted young pitcher, but he is only 19 and probably a minimum of two years away from the majors.
