If you're a fantasy baseball player, especially in a keeper league, and you don't have our Pipeline prospects stats section bookmarked, you're missing out on a huge tool to help you win.

We use it all the time to form our top 10 fantasy prospects list of guys currently in the Minors. For instance, you can look at a list of all 900 prospects on team Top 30 lists and their stats over the past 30 days, because we all know that just looking at season-long stats does not tell a full picture, especially when trying to predict who might be the next big callup to the big leagues.

You can then sort by any of the statistical categories or by level, so you can see who at the upper levels are hot as of late. You're welcome.

And you're welcome for the following updated top 10 fantasy prospect list, as always based on potential 2018 fantasy production in the big leagues. For long-term, overall baseball value, our Top 100 list is still the place to go.

1. Eloy Jimenez, OF, White Sox (Previous rank: 2)
Not as red hot as he was, Jimenez still has an .849 OPS over the past 30 days, with a season line of .315/.364/.558. That .849 OPS is still much better than any White Sox outfielder in the big leagues over the same time span.

2. Vladimir Guerrero Jr., 3B, Blue Jays (Previous rank: 1)
Vlad Jr.'s knee injury, expected to keep him out around a total of four weeks, does put a damper on what we hoped would be his ascension to Toronto. But his 1.172 OPS over the past 30 days tops all qualified (on team top 30 lists) hitters. Expect Guerrero to come back, keep raking and continuing to put pressure on the Jays' front office to find room for his bat.

3. Kyle Tucker, OF, Astros (Previous rank: 3)
I'm as big a Tony Kemp fan as there is, but does he strike you as a starting left fielder for a championship team? Tucker continues to provide the potential for homers (9 in 2018) and steals (8) for fantasy owners. And even if he's slowed down a touch of late, his .907 OPS over the past 30 days is much better than Kemp's (.781).

4. Nick Senzel, 3B/2B, Reds (Previous rank: 6)
There may not be an apparent spot for Senzel to play in Cincy right now, with Eugenio Suarez and Scooter Gennett producing well, but it's clear Senzel has shaken off the ill effects of his bout with vertigo. He's hit .327 since he came back on May 29 and has gone 10 for his past 19, raising his average from .271 when he went on the DL up to .293 as of Thursday.

5. Michael Kopech, RHP, White Sox (Previous rank: 4)
Chicago's rotation has been better of late, some (Lucas Giolito, 4.91 ERA; Hector Santiago, 4.82) still have scuffled over the past 30 days. It'd be easier to pound the table for Kopech if he had been more consistent. His 4.70 ERA in the past 30 days isn't pretty, but his 12.5 K/9 rate is. Kopech whiffed 10 in his last start, so keep an eye to see if he gets hot.

6. Christin Stewart, OF, Tigers (Previous rank: 7)
JaCoby Jones has a .572 OPS over the past 30 days. Stewart, even with less power production than earlier in the year, is at .714. He still leads the International League with 13 homers, while Jones has five and Stewart's .884 OPS for the season is almost 230 points better than Jones.

7. Justus Sheffield, LHP, Yankees (Previous rank: Unranked)
Somewhat quietly, Sheffield has moved up to Triple-A and continued to pitch well. The walk rate could come down a touch, but he's struck out 10.7 per nine for the year. Throw out one awful start in Triple-A, and he's allowed just three earned runs in 22 1/3 innings at the level. Meanwhile, Domingo German keeps getting the ball despite a 5.23 ERA.

8. Fernando Tatis Jr., SS, Padres (Previous rank: Unranked)
All the other teenage types in the upper levels were hitting and you knew it was just a matter of time until Tatis Jr. joined them. He has an OPS of 1.000 over the past 30 days and now sports a .280/.358/.506 line with 11 homers and eight steals for the year. In San Diego, Freddy Galvis has a .635 OPS for the year at shortstop.

9. Keston Hiura, 2B, Brewers (Previous rank: Unranked)
Hiura is living up to his billing as the most advanced hitter in the 2017 Draft class, with a promotion to Double-A hardly slowing him down. He's hit .402/.468/.643 over the past 30 days (.378/.440/.578 in his first 12 Double-A contests) to bring him to a robust .331/.392/.538 combined line for the season.

10. Willie Calhoun, OF, Rangers (Previous rank: 9)
We're still big believers in Calhoun's bat, and while he hasn't been as productive as he has in previous years, his .280/.328/.424 line isn't terrible. He's also hit .333/.375/.578 in his first 10 June games, with a pair of homers and eight RBIs, so keep an eye on him.

Dropped out: Willy Adames, SS, Rays (Previous rank: 5); Austin Riley, 3B, Braves (Previous rank: 8) ; Mitch Keller, RHP, Pirates (Previous rank: 10)
