Our annual midsummer overhaul of MLB Pipeline's Top 100 Prospects list is still a month away. Before we get to that, we're back with our second series of tweaks.
We now have two-plus months of Minor League performance to evaluate, compared to a month when we made our first series of adjustments in early May, so we were more aggressive this time around.
:: Complete prospect coverage ::
When we reconsidered the top 15 prospects on the list, we left only the top two guys (Braves outfielder Ronald Acuna Jr., Blue Jays third baseman Vladimir Guerrero Jr.) in place. We also moved 15 players up and eight down by a significant amount, and added five new prospects at the bottom of the Top 100:
The Top 15

Juan Soto, OF, Nationals (No. 13 to No. 3)
Nineteen-year-olds aren't supposed to jump from Class A to the big leagues in six weeks and hit .326/.423/.596 with six homers in their first 27 games in the Majors.

Kyle Tucker, OF, Astros (No. 14 to No. 10)
After selling out a bit for power while slamming a career-high 25 homers in 2017, he's showing more patience while continuing to drive the ball and looks like a perennial 20-20 player.

Royce Lewis, SS, Twins (No. 18 to No. 13)
The No. 1 overall pick in the 2017 Draft has been everything expected offensively and better than anticipated at shortstop.

Francisco Mejia, C, Indians (No. 11 to No. 17)
He didn't cross the Mendoza Line for good until June 3, and while he's starting to hit like his old self, there are increasing concerns that he lacks the receiving skills to be an everyday catcher.
Thirteen prospects in our previous top 15 moved at least slightly, so we're not going to break them all down individually. Padres shortstop Fernando Tatis Jr. leaped over Reds third baseman Nick Senzel and Nationals outfielder Victor Robles into our top five. Astros right-hander Forrest Whitley remained just ahead of White Sox righty Michael Kopech as the highest-ranked pitcher, though both slid out of the top 10.
Risers

Mike Soroka, RHP, Braves (No. 26 to No. 16)
He's always had polish, his stuff seems to get better every year and he has looked at home in Atlanta at age 20.

Jesus Luzardo, LHP, Athletics (No. 31 to No. 22)
His pitchability and his changeup rank among the best in the Minors, and he's a rare southpaw who can hit 98 mph with his fastball.

Keston Hiura, 2B, Brewers (No. 48 to No. 32)
Regarded as the best pure hitter in the 2017 Draft, he has looked exactly like that while batting .335/.392/.534 and reaching Double-A in his first full pro season.

Jesus Sanchez, OF, Rays (No. 49 to 37)
A natural hitter with the chance for solid tools across the board, he's thriving in Class A as a 20-year-old.

Jo Adell, OF, Angels (No. 53 to No. 38)
Questions about his ability to handle quality pitching dogged him as an amateur but didn't stop him from going 10th overall in the 2017 Draft, and he's dispelling them by hitting .318/.373/.617 with 14 homers and 11 steals in 50 games across two Class A levels.

Dylan Cease, RHP, White Sox (No. 52 to No. 43)
He's making strides with his control and command, and his mid-90s fastball and hammer curveball are as good as ever.

Dane Dunning, RHP, White Sox (No. 65 to No. 56)
While he doesn't have the sexiest stuff among White Sox starting pitcher prospects, he commands a solid arsenal and looks like a lock to be a mid-rotation starter.

Austin Riley, 3B, Braves (No. 72 to No. 52)
He continues to improve at tapping into his considerable power potential and playing the hot corner, so it might not be long before Atlanta summons him.

Tyler O'Neill, OF, Cardinals (No. 73 to No. 53)
With 46 homers in 171 Triple-A games, he has nothing left to prove in Triple-A but no path to immediate playing time in St. Louis.

Yordan Alvarez, OF/1B, Astros (No. 74 to No. 54)
Plucked from the Dodgers in a trade before making his pro debut, he has raked ever since and looks like he'll hit for plenty of average and power.

Carter Kieboom, SS, Nationals (No. 79 to No. 66)
There may not be another shortstop prospect who can match his combination of hitting ability, power, patience and consistent contact.

Sean Murphy, C, Athletics (No. 92 to No. 70)
Not only is his combination of arm strength and receiving ability as good as any catcher's in the Minors, but he's also improving as a hitter and making the most of his raw power.

Alex Kirilloff, OF, Twins (No. 98 to No. 71)
The Rookie-level Appalachian League MVP in his 2016 pro debut, he missed all of last season following Tommy John surgery and has reclaimed his all-around hitting ability this spring.

Andres Gimenez, SS, Mets (No. 99 to No. 72)
He's more advanced offensively than Amed Rosario was at the same stage (age 19) and is no slouch with the glove either.

Peter Alonso, 1B, Mets (No. 100 to No. 73)
He somehow hasn't gotten the acclaim that should come from hitting .301/.390/.543 in two-plus years as a pro.

Fallers

Austin Hays, OF, Orioles (No. 32 to unranked)
The first player from the 2016 Draft to reach the Majors, he has battled shoulder and ankle injuries this year and batted .224/.259/.375 in Double-A.

Heliot Ramos, OF, Giants (No. 54 to No. 74)
The five-tool ability and huge ceiling are still there, though he's going to need to cut down on his strikeouts.

Jorge Mateo, SS/OF, Athletics (No. 62 to No. 76)
His approach at the plate has disintegrated, which makes it difficult for him to take advantage of his game-changing speed.

Chance Adams, RHP, Yankees (No. 66 to unranked)
With his command regressing as he repeats Triple-A, he looks like he might be more of a reliever than a mid-rotation starter.

J.B. Bukauskas, RHP, Astros (No. 67 to unranked)
He has wipeout stuff but can't always locate it where he wants, and he has made just two starts this year because of an undisclosed injury.

Stephen Gonsalves, LHP, Twins (No. 69 to No. 77)
After dominating at every previous level of the Minors, he hit the wall in Triple-A at the end of 2017 and again this year.

Pavin Smith, 1B, D-backs (No. 81 to unranked)
The No. 7 overall pick in the 2017 Draft is controlling the strike zone, but an advanced college hitter should produce better than a .229/.337/.379 line in Class A Advanced.

D.J. Peters, OF, Dodgers (No. 96 to unranked)
His power is jaw-dropping but his 32 percent strikeout rate in Double-A is worrisome.
New Additions

Griffin Canning, RHP, Angels (unranked to No. 96)
Concerns about his pre-Draft MRI knocked him from the first round to the second in 2017, yet he has reached the mid-90s with his fastball and showed an array of solid secondary pitches while reaching Triple-A just 12 starts into his pro debut this year.

Ke'Bryan Hayes, 3B, Pirates (unranked to No. 97)
He has shown the ability to put the bat on the ball and play a fine third base, and now he's starting to display the power scouts always believed he had.

Brusdar Graterol, RHP, Twins (unranked to No. 98)
Two years removed from Tommy John surgery, he can hit 100 mph and also miss bats with both his slider and curveball.

Zack Collins, C, White Sox (unranked to No. 99)
While his power and patience were evident in his first two pro seasons, he's hitting the ball with more authority in 2018.

Christin Stewart, OF, Tigers (unranked to No. 100)
He's an all-bat guy, but his bat has produced 81 homers in 402 pro games.
