These 10 prospects will make an impact soon

Eloy, Vlad Jr., Luzardo have the best chance of making fantasy splash

The Minor League season will be wrapping up at the end of August/beginning of September. We're not quite at the considering-September-callups point of the year, but we aren't far off. And as more teams fall out of contention, perhaps it's a bit easier to get a sense of where some opportunities may arise for prospects to show what they can do.

For this week's Fantasy Top 10, I'm going back to our outstanding Prospects Stats section for help. Looking at the past 30 days isn't a fail-safe, but it does give a snapshot of who's been performing well down the stretch and then might be more likely to carry that over to a final month or so in the big leagues.

For this week's Fantasy Top 10, I'm going back to our outstanding Prospects Stats section for help. Looking at the past 30 days isn't a fail-safe, but it does give a snapshot of who's been performing well down the stretch and then might be more likely to carry that over to a final month or so in the big leagues.

Here are our updated rankings of the top 10 fantasy prospects presently in the Minors. As always, they're based on expected 2018 fantasy production in the big leagues, while our Top 100 reflects long-term value in all phases of the game.

1. Eloy Jimenez, OF, White Sox No. 1/No. 3 overall (Previous rank: 1)
In the past 30 days, all Jimenez has done is hit .413/.438/.800 with seven homers, and he has just 12 strikeouts in 80 plate appearances. White Sox outfielders still aren't lighting the world on fire, and Jimenez is already on the 40-man roster. What else does he need to do?

2. Vladimir Guerrero Jr., 3B, Blue Jays No. 1/No. 1 overall (Previous rank: 3)
Absolutely no one should be surprised that Guerrero quickly adjusted to life in Triple-A. His first homer on Wednesday might still be travelling and he's hit .462/.571/.769 in nine games with Buffalo. For the year, Guerrero is now at .407/.462/.678. A callup to Toronto would be a terrific reward for a fantastic season.

3. Kyle Tucker, OF, Astros No. 2/No. 8 overall (Previous rank: 4)
It's a shame Tucker's rough big league debut has bothered him back down in Triple-A. He's hit .406/.441/.719 in seven games since being back with Fresno. That includes a homer in each of his past three games and a stolen base in three of his past four. Tucker now has 17 in each of those categories and remains the best power-speed combination who could actually help your fantasy squad out should he get another shot.

4. Michael Kopech, RHP, White Sox No. 2/No. 13 overall (Previous rank: 6)
We've been riding the Kopech roller coaster all year, but he has been very, very good for a fairly extended period of time now. He has given up two runs or less in his last five starts (2.32 ERA) and has continued to miss a ton of bats (41 K's in 31 innings). But what's been most impressive is that Kopech has walked just four in that span for a tidy 1.00 WHIP.

5. Francisco Mejia, C/OF, Padres No. 3/No. 21 overall (Previous rank: 2)
Mejia's certainly hit well enough since he joined the Padres, with a .311/.385/.422 line in 13 games. He has also only caught, which does limit his flexibility and thus, his opportunity. But it sure would be nice for the Padres, who are playing for the future, to give Mejia the chance to show what he can do with San Diego.

6. Alex Verdugo, OF, Dodgers No. 1/No. 28 overall (Previous rank: 5)
It's nothing new that Verdugo is hitting well (.333/.416/.436 over the past 30 days), albeit without much power. He is slugging .490 for the season, and there is extra-base pop for sure. There might not be much room in the Dodgers' outfield, but we all know Verdugo can handle the bat if he gets the chance.

7. Victor Robles, OF, Nationals No. 1/No. 5 overall (Previous rank: 7)
Robles hasn't actually been dominating, but at least he's back and healthy. And he has nine steals in 17 games in Triple-A. The tools are too fantastic to ignore, even if you have to stash him on your reserves (for those of you in keeper leagues).

8. Jesus Luzardo, LHP, A's No. 1/No. 12 overall
In his past five starts, Luzardo has a 0.69 ERA and a 0.92 WHIP. Seriously. The lefty tossed five shutout innings and struck out six in his Triple-A debut. That's now three levels Luzardo has dominated this year, to the tune of a 2.01 overall ERA and a .203 BAA. You can't tell me he can't help the A's out down the stretch.

9. Peter Alonso, 1B, Mets No. 2/No. 63 overall (Previous rank: NR)
Alonso keeps on doing what he does, with a .316/.368/.705 line and nine homers over his past 106 plate appearances. He leads the Minors with 101 RBIs, and his 28 combined homers are third most. Alonso is a definite upgrade over Wilmer Flores, right?

10. Dylan Cease, RHP, White Sox No. 5/No. 44 overall (Previous rank: NR)
OK, so maybe this is a long shot since Cease's only in Double-A and the White Sox haven't even called up Kopech. But keeper leaguers, get this guy now. His past 30 days looks like this: 24 IP, 1.13 ERA, 0.71 WHIP, 35 K's. Cease has been about as dominant of late as any pitching prospect in the game.

Dropped out: Mitch Keller, RHP, Pirates (Previous rank: 8); Keston Hiura, 2B, Brewers (Previous rank: 9); Luis Urias, 2B/SS, Padres (Previous rank: 10)
