Baseball Prospectus moved three top Dodger prospects up in its midseason rankings: Julio Urias (35th to 15th), Joc Pederson (50th to 17th) and Corey Seager (44th to 19th). That’s right: Baseball Prospectus now considers the Dodgers to have three top 20 prospects in the minors.

Update: Corroboration. Here’s the Baseball America midseason list, with Urias at 13 (up from 51 at the end of 2013), Seager at 16 (up from 37) and Pederson at 18 (up from 34).

Here are Baseball Prospectus’ comments:

Urias: “The youngest prospect on the Top 50 at just 17, Urias has not only earned his accelerated path to the big leagues, he’s flourished, striking out more than a batter an inning and flashing above-average stuff. He’s still working on some things, like his fastball command and comfort with the changeup, but he could get a taste of Double-A before the season is done. As long as he continues to show progression, the Dodgers will continue to challenge him. He has earned a spot as the No. 8 pitching prospect in the game.” – Chris Rodriguez

Pederson: “In any other organization, he’d already be in the majors and accruing major-league service time on the DL for his current shoulder injury, but the Dodgers crowded outfield situation has Pederson blocked. With long-term effects not a major concern, the profile once thought to have some “tweener” qualities has now shown enough power and plate discipline to play every day, even if it’s on a corner, and enough defense to handle center when called upon.” – Jeff Moore

Seager: “The 6-foot-4 shortstop has done nothing but impress after a brief hiccup the last month of the 2013 season. The debate over whether he’s a first or second division player is quickly evaporating with each line drive in the gap. The question now becomes whether he can stay at shortstop, and by some accounts, including my own, it appears he can — for the time being, at least. His glove is above average and he plays the position with the smoothness of a seasoned veteran, not of a 20-year-old. Put all of this together and you get a top-20 prospect. – Chris Rodriguez
