There have been several big-name prospects who have reached the Major Leagues since the last installment in this series, though none have more potential to impact a fantasy season than the Brewers' Lewis Brinson.
Brinson, Milwaukee's top prospect and No. 13 on MLBPipeline.com's Top 100 Prospects list, was called up from Triple-A Colorado Springs in the wake of Ryan Braun landing on the disabled list with a calf injury. At the time, the 23-year-old outfielder was hitting .312/.397/.503 with 20 extra-base hits and seven steals through 45 games.
He hasn't fared as well during his time in the Majors, going 3-for-22 (.136) with 11 strikeouts while appearing in parts of nine games, and has lost some reps to a suddenly hot Keon Broxton, but Brinson possesses the type of power-speed combination that could make him an asset for fantasy owners the rest of the way.

1. Yoan Moncada, 2B, White Sox (Previous rank: 1)
Moncada scuffled initially upon his return from the disabled list for a thumb injury, but MLBPipeline.com's No. 1 prospect has been red-hot of late, hitting .429 with nine hits, six runs and more walks (six) than strikeouts (five) in his last five games for Triple-A Charlotte. Yolmer Sanchez has provided the White Sox with a nice stopgap ahead of Moncada, though it's time they turn over the position to the 22-year-old phenom.
2. Amed Rosario, SS, Mets (Previous rank: 2)
Both Asdrubal Cabrera and Neil Walker are injured and Jose Reyes is manning shortstop. Rosario, meanwhile, has done nothing but impress on both sides of the ball at Triple-A Las Vegas, where he's hitting .326 with 25 extra-base hits and 12 steals through 69 games. While it's hard to justify Rosario not already being in the big leagues, the No. 3 overall prospect's time should come soon enough.
3. Austin Meadows, OF, Pirates (Previous rank: 3)
Meadows appeared to be turning the corner when he batted .300 in May, but he's struggled to build on that momentum this month, with a .214 average through 14 games. Andrew McCutchen and Gregory Polanco have fared better lately, and Starling Marte is nearing his return from an 80-game suspension, but at some point, it makes sense for Pittsburgh to give its top prospect a taste of the Major Leagues.
4. Reynaldo Lopez, RHP, White Sox (Previous rank: 4)
While David Holmberg has filled in admirably for injured Dylan Covey in the White Sox rotation, Chicago has a host of promising young arms waiting in the wings at Triple-A Charlotte. Lopez, with his upper-90s fastball and power curve, headlines that group and has outpitched both Lucas Giolito and Carson Fulmer, going 5-3 with a 3.91 ERA and 64 strikeouts in 71 1/3 innings.

5. Rhys Hoskins, 1B, Phillies (Previous rank: 5)
Hoskins hit a pair of solo shots for Triple-A Lehigh Valley on Monday and now leads the International League with 17 homers -- this after he finished second in the Minors with 38 homers in 2016. Tommy Joseph has helped his cause by rebounding from an early April slump, but it's the 24-year-old Hoskins who's the club's first baseman of the future.
6. Ozzie Albies, 2B, Braves (Previous rank: 8)
A sore foot led to a brief stint on the disabled list for Albies, but he's batting .344 with six extra-base hits and three steals in seven games since rejoining Triple-A Gwinnett. He's shown improvement in all three months this season, seemingly setting the stage for an inevitable promotion once the rebuilding Braves decide to trade veteran Brandon Phillips.
7. Luke Weaver, RHP, Cardinals (Previous rank: NR)

Michael Wacha has completed five innings just once in his last five starts for the Cardinals, and he's allowed four or more earned runs in three of those turns. Should St. Louis decide to move Wacha to the bullpen, Weaver, who's gone 6-1 with a 2.33 ERA in nine starts for Triple-A Memphis, could be called on to fill his spot in the rotation.

8. Chance Adams, RHP, Yankees (Previous rank: NR)
With Carsten Sabathia on the disabled list and Luis Cessa struggling as a fill-in, Adams finds himself in a position to make an impact sooner than later. He'd be better off spending much of the season in Triple-A Scranton/Wilkes-Barre, but there's little doubt that Adams, with his swing-and-miss stuff and impressive track record, is firmly in the mix, especially as the Yankees continue to flounder in the month of June.
9. Zack Burdi, RHP, White Sox (Previous rank: 10)
Closer Player Page for David Robertson has long been viewed as a top trade candidate, largely because the White Sox have Burdi, the club's future closer, champing at the bit in Triple-A. The 2016 first-rounder has pitched better than his 5.00 ERA suggests, as he's allowed just two home runs (0.6 HR/9) while racking up 42 strikeouts in 27 innings (14.0 K/9).
10. Erick Fedde, RHP, Nationals (Previous rank: NR)
An ongoing lack of stability in Nationals' big league bullpen prompted the club to move Fedde to the bullpen at Double-A Harrisburg in mid-May. Having since advanced to Triple-A Syracuse -- thanks to a 24-to-4 strikeout-to-walk ratio in 16 1/3 innings -- he could be a sleeper candidate for saves during the second half.
