If you haven't checked out my midseason top 25 prospects yet, you should.

But 25 names (or 43, if you count the honorable mentions) don't give a complete picture of the prospect landscape and may only be telling those who would most benefit from such a list, the long-term keeper league owners, what they already know.

So for them, I offer supplemental material. Others are free to read it too, of course (and to share it with everyone they know -- cha-ching!), but the idea here is to highlight the best of the prospects who might actually still be available in leagues where prospects are paramount.

And why might they still be available? Well, because no one thought much of them coming into the season, at least not like they do now. So they've improved their stock, and I'm here to tell you about it.

Let's get on with it.

All stats are updated through Wednesday, July 13.

1. Josh Hader, SP, Brewers

Bats: Left | Throws: Left
Age: 22 (4/7/94)
2016 levels: Double-A, Triple-A
2016 stats: 2-3, 2.56 ERA, 1.21 WHIP, 81 IP, 33 BB, 104 K
Hader wasn't the most notable prospect to come over in the Carlos Gomez deal last July, but he's clearly the headliner now, emerging as a big-time bat-misser with a sinister fastball/slider combo. He had a 0.95 ERA in 11 starts before his promotion to Triple-A, where he's working to develop a changeup.

2. Reynaldo Lopez, SP, Nationals

Bats: Right | Throws: Right
Age: 22 (1/4/94)
2016 levels: Double-A, Triple-A
2016 stats: 4-5, 3.19 ERA, 1.25 WHIP, 87 1/3 IP, 31 BB, 109 K
Lopez's potential was evident in his 100-mph fastball, but only now is he missing bats like he should. His delivery gives him durability concerns, but the bigger issue might be breaking into that already-stacked Nationals starting rotation.

3. Ian Happ, OF, Cubs

Bats: Both | Throws: Right
Age: 21 (8/12/94)
2016 levels: high Class A, Double-A
2016 stats: .310 BA (306 AB), 9 HR, 13 SB, .894 OPS, 52 BB, 79 K
Seems funny to say the ninth overall pick last year has greatly improved his stock, but in a seemingly bottomless Cubs system, Happ has gone from being just another guy to the next big thing -- and a possible Ben Zobrist clone as a hybrid infielder/outfielder.

4. Chris Paddack, SP, Padres

Bats: Right | Throws: Right
Age: 20 (1/8/96)
2016 levels: low Class A
2016 stats: 2-0, 0.96 ERA, 0.54 WHIP, 37 1/3 IP, 3 BB, 63 K
You wonder why a Marlins fan might not be so thrilled with the Fernando Rodney deal? The numbers pretty much tell the story here, in particular the strikeout and walk rates, with one omission: In his final three starts before the trade, Paddack didn't allow a single hit.

5. Luke Weaver, SP, Cardinals

Bats: Right | Throws: Right
Age: 22 (8/21/93)
2016 levels: Double-A
2016 stats: 4-2, 1.48 ERA, 1.11 WHIP, 48 2/3 IP, 7 BB, 57 K
We're still trying to wrap our heads around just who Weaver is after he missed the first two months with a fractured wrist. He struck out too few batters to take his 1.62 ERA at high Class A last year seriously, but now his four-pitch arsenal is making him look like Corey Kluber.

6. Tyler O'Neill, OF, Mariners

Bats: Right | Throws: Right
Age: 21 (6/22/95)
2016 levels: Double-A
2016 stats: .304 BA (319 AB), 17 HR, .917 OPS, 34 BB, 89 K
His 32 home runs last year didn't really stand out in the hitter-friendly California League, but now that O'Neill is hitting for average in a more neutral environment, he's suddenly looking like a big part of the Mariners' future. The reduced strikeout rate suggests sustainability, too.

7. Christin Stewart, OF, Tigers

Bats: Left | Throws: Right
Age: 22 (12/10/93)
2016 levels: high Class A
2016 stats: .253 BA (277 AB), 20 HR, .938 OPS, 65 BB, 89 K
This Christin Stewart actually smiles for the camera and has good reason to with a power/patience profile that should eventually make him a much bigger deal than Steven Moya. Victor Martinez is in the twilight of his career, you know.

8. Hunter Dozier, 3B, Royals

Bats: Right | Throws: Right
Age: 24 (8/22/91)
2016 levels: Double-A, Triple-A
2016 stats: .330 BA (315 AB), 17 HR, .972 OPS, 33 BB, 80 K
There was a time when Dozier was highly regarded as the eighth overall pick in the 2013 draft, but then he hit .213 at Double-A last year and that was that. Until this. Defensive concerns are suppressing the hype in a year when the Royals are hurting for offense.

9. Sean Reid-Foley, SP, Blue Jays

Bats: Right | Throws: Right
Age: 20 (8/30/95)
2016 levels: low Class A, high Class A
2016 stats: 8-3, 2.22 ERA, 0.97 WHIP, 89 1/3 IP, 29 BB, 97 K
The former second-rounder's swing-and-miss stuff was lost in all the walks last year, but you see the difference a little control makes. The move to Double-A will be the big test, but Reid-Foley is suddenly ahead of schedule at age 20.

10. Aaron Wilkerson, SP, Brewers

Bats: Right | Throws: Right
Age: 27 (5/24/89)
2016 levels: Double-A, Triple-A
2016 stats: 6-3, 2.06 ERA, 1.01 WHIP, 96 1/3 IP, 26 BB, 105 K
You could make the case for Wilkerson to be even higher on this list given that he's just two years removed from pitching in the independent leagues, becoming a somebody almost overnight as part of the Aaron Hill deal. But at his age, it could go away just as quickly. We'll find out soon whether he sinks or swims.

Honorable mentions

Rhys Hoskins, 1B, Phillies: Hoskins has gone from being a dime-a-dozen corner infield bat to the minor-league leader in home runs, but playing this season at the notoriously hitter-friendly (and frequently misleading) Double-A Reading may have something to do with it.

Dylan Cozens, OF, Phillies: The former defensive end put on a show in batting practice at the Futures Game and has the size and speed to play most any sport. However, he may be even more a product of Double-A Reading than Hoskins, hitting just four of his 24 home runs on the road with an OPS about .500 points lower.

Ryon Healy, 3B, Athletics: Healy, who's now on his way to the big leagues, looks like he should hit more home runs than he does and profiles as sort of a Billy Butler-type player. But his .325 batting average and .942 OPS aren't just products of the hitter-friendly Pacific Coast League, actually falling some since his promotion from neutral Double-A Midland.
