But before this year's Draft gets underway, let's see how last year's first-rounders are doing (all statistics through June 1).
Mark Appel, RHP, Astros, Lancaster (Class A Advanced): After Appel struggled in April to adjust to the piggyback system the Astros use for their Minor League starters, Houston sent him back to extended spring camp to build up his stamina. He returned to Lancaster last week but was roughed up in his first start back.

Dominic Smith, 1B, Mets, Savannah (Class A): Grayson Stadium, Savannah's home park, can swallow even the best left-handed power hitters. Smith, who might have been the best prep hitter in the 2013 class, doesn't have a homer yet, but he showed improvement last month. He hit .320/.398/.360 in May and is hitting .265/.330/.302 overall.

Rankings: Top 20 Padres (No. 5)
Reese McGuire, C, Pirates, West Virginia (Class A): Whereas Meadows, the Pirates' first pick, has been hampered by injury, McGuire has anchored West Virginia's lineup. He's hitting .291 with a .694 OPS while managing the Power's pitching staff.

Rankings: Top 100 (No. 64) | Top 20 D-backs (No. 2)

Rankings: Top 20 Dodgers (No. 5)
Marco Gonzales, LHP, Cardinals, Springfield (Double-A): Gonzales was a two-way player and has moved quickly since the Cards selected him as a pitcher. He opened the year at Class A Advanced Palm Beach and earned a promotion to Springfield in mid-May. He's made three starts at Double-A, striking out 19 and walking four in 16 innings.
Rankings: Top 20 Cardinals (No. 4)
Jonathon Crawford, RHP, Tigers, West Michigan (Class A): Crawford has pitched well in the Midwest League. In nine starts, he has a 2.27 ERA and a 44-to-14 strikeout-to-walk ratio in 47 2/3 innings.
Rankings: Top 20 Tigers (No. 4)
Nick Ciuffo, C, Rays, extended spring: The Rays typically take a conservative approach with their prospects, and Ciuffo is no different. He stayed in Port Charlotte for extended spring camp and will likely join a short-season club when their seasons begin in a few weeks.
Rankings: Top 20 Rays (No. 6) | Top 10 catchers (No. 8)
Hunter Harvey, RHP, Orioles, Delmarva (Class A): Harvey was so sure that he wanted to play professionally after high school that he didn't even bother committing to a college.

Travis Demeritte, 2B/SS, Rangers, Hickory (Class A): Demeritte was a compensation pick after the Rangers lost Josh Hamilton in free agency.

Rankings: Top 20 Rangers (No. 13)
Jason Hursh, RHP, Braves, Mississippi (Double-A): The Braves have shown a willingness to push college starters aggressively in the Minor Leagues, and they are doing the same with Hursh. He began his first full professional season in Mississippi, where he is 4-4 with a 3.68 ERA in 11 starts.
Rankings: Top 20 Braves (No. 3)
Aaron Judge, OF, Yankees, Charleston (Class A): Judge strained a quad last summer, delaying his professional debut until this spring. Now healthy, the former Fresno State slugger is hitting .316/.410/.497 with seven home runs in 54 games for Charleston.
