#4: JULIO URIAS, DODGERS, LHP
AA TULSA: 1-2, 3.00 ERA, 36 IP, 9 BB, 46 K
The Dodgers signed Urias out of Mexico at 16, and he quickly became one of the game's top prospects. In deference to his age, the Dodgers have limited his workload — he pitched 88 innings last season, and he paused at 36 innings this season so he could undergo cosmetic surgery on his left eye. He returned to action last week, but the midseason break could leave him fresh to help the Dodgers as a 19-year-old September call-up — just as a 19-year-old Fernando Valenzuela helped the Dodgers in September 1980.
#16: HECTOR OLIVERA, DODGERS, IF
AA/AAA: .354 BA, .400 OBP, 2 HR, 65 AB
After more than a decade in the Cuban league — the last half as one of its most prolific hitters — Olivera defected last year. That gave major league clubs the chance to buy a bat in the prime of his career. The Dodgers did, for $62.5 million, and the 30-year-old Olivera could be in the majors any day now. He plays second base and third base, and his imminent promotion could make fellow Cuban Alex Guerrero expendable.
#20: JOSE DeLEON, DODGERS, RHP
A/AA: 6-5, 3.13 ERA, 89 IP, 31 BB, 122 K
DeLeon , a 24th-round pick, could become the first member of the Dodgers' 2013 draft class to make the major leagues. He lost weight, gained velocity and shot up through the minors — four starts in the Class A Midwest League, seven in the Class A California League, now nine in the double-A Texas League. The Dodgers could keep him and Urias for what could be their post-Zack Greinke future next year, but the 22-year-old De Leon could be their most attractive trade chip, a headliner in a deal for, say, Cole Hamels.
#37: SEAN NEWCOMB, ANGELS, LHP
Low A/High A: 5-1, 2.48 ERA, 83 IP, 44 BB, 106 K
Newcomb pitched a perfect inning in Sunday's Futures Game, with a fastball sitting at 93-95 mph and a snappy curve. He needs work on his changeup and command — he walks too many batters to get deep into games — but he is in his first full pro season, and the Angels are happy with his progress. Newcomb, 22, was the Angels' first-round pick last year, after forfeiting their first-round picks in 2012 and 2013 after the signings of Albert Pujols and Josh Hamilton, respectively.
