The Dodgers have signed their top nine draft picks with this news from Tony Jackson of ESPNLosAngeles.com:The Dodgers reached agreement on Monday with former Oklahoma City University right-hander Ryan O'Sullivan, their fourth-round selection in this year's amateur draft. The agreement came hours before the deadline for signing this year's picks and just four days after the club finalized an agreement with first-rounder Chris Reed, a pitcher out of Stanford University. O'Sullivan, who will turn 21 next month, is the brother of former Los Angeles Angels pitcher Sean O'Sullivan, now with the Kansas City Royals. He never actually pitched at Oklahoma City, redshirting there this season after transferring from San Diego State, where he went 4-4 with a 6.71 ERA in two seasons.
