There are more on the way. A scout who has seen much of the Dodgers' system this year had this to say about three of the pitchers currently in the Dodgers' Top 10.
Zack Lee (No. 36 overall; No. 1 Dodgers prospect): "He's really athletic with a good delivery. He really commands the fastball with an advanced feel for the strike zone. He can make his fastball cut and sink. He has a Zack Greinke-like feel for the zone. The rest of his stuff is a projection. His curve, slider and changeup are all presently below-average. They will be average across the board with plus command. I was expecting power stuff and that he'll have to learn how to pitch. But his advanced feel for pitching is his strength. He's not a top-of-the-rotation guy for me, but more like an innings eater. He'll be able to pitch with his stuff, but not dominate with it."
Angel Sanchez (No. 6 Dodgers prospect): "He has a plus fastball, up to 95 mph, and a plus changeup. His breaking ball has flashes, but it has a ways to go. He's probably a bullpen guy for me, a solid seventh-inning guy because of the lack of the breaking ball. He doesn't pitch at 95 mph, he pitches more with an average fastball. But out of the 'pen, maybe the fastball plays up."
Shawn Tolleson (No. 9 Dodgers prospect): Tolleson gwas called up on June 4 and the scout saw him while he was still in Triple-A. "He was really good. A late Draft pick, Tommy John surgery out of high school, arm issues at Baylor. So he hasn't been pitching long. But he has two plus-plus pitches with his fastball and slider. He has a funky delivery; it's not the best arm action, but he's lights out with surprising good command."
