Skaggs, who reported to Class A South Bend on Saturday afternoon, was rated as the Angels' eighth best prospect by Baseball America before the season. The 19-year-old compiled an 8-4 record and 3.64 ERA in 19 games (14 starts) for the Angels' Class A Cedar Rapids.
Dipoto said Skaggs features an 88-93-mph fastball as well as a changeup and curveball -- a repertoire that attracted Arizona's brass to him in the 2009 First-Year Player Draft, though it was Los Angeles that selected him 40th overall.
"He was a guy we definitely wanted," said Dipoto, who scouted Skaggs at Santa Monica (Calif.) High School and expects the 6-foot-4, 195-pound Skaggs to pick up speed on his fastball as his body fills out. "It took a year, but now we got him."
The Angels were not eligible to trade Skaggs, who signed his pro contract on Aug. 7, 2009, until he spent one full year in their organization. He hasn't pitched in a Minor League game since July 23 to avoid the risk of injury while he was held in limbo.
As a result of the layoff, Dipoto said, Skaggs will throw two-to-three bullpen sessions and two simulated games before pitching in Midwest League games. The plan is for him to throw one-to-two-inning outings for the remainder of the season.
"After two weeks down, we don't want to ramp him back up and expect him to go out there and throw five or six innings this year," Dipoto said. "No rush for us."
There is no rush in Skaggs' development, Dipoto explained, because Arizona acquired Major League starters Joe Saunders (in the Haren trade) and Daniel Hudson (in the July 30 trade of Edwin Jackson), along with Minor League pitching prospects Patrick Corbin and David Holmberg.
For Haren, the Angels also previously shipped to Arizona reliever Rafael Rodriguez, who was called up Wednesday but hadn't appeared in a game heading into Saturday.
