OOPSY Peak Dynasty Insights: Kade Anderson Leads the Board, River Ryan on the Climb

Kade Anderson is the No. 1 prospect on the OOPSY Peak board, but he doesn’t own its biggest projection. That belongs to 19-year-old catcher Rainiel Rodriguez, whose 5.2 Peak WAR tops the entire top 100 from the No. 3 spot. Peak WAR is the average MLB Wins Above Replacement OOPSY expects during the peak of a player’s career. Using aging curves and minors-to-majors translations, it projects every player to that peak, so a 19-year-old in Double-A and a 21-year-old already in the majors can be compared on the same scale. Here is how the board looks as of 11/2/2026, who moved this month and four younger names worth stashing.

Two Mariners Lead the Top Five

Kade Anderson (SEA, SP) holds the No. 1 spot at age 21 with 4.4 Peak WAR (No. 35 overall on Peak), the 4th-best mark in the top 100. OOPSY projects a 3.20 ERA, 161 strikeouts in 151 innings and a 1.17 WHIP at his peak.

His Seattle teammate Lazaro Montes (RF) sits second at age 21 with 3.9 Peak WAR (No. 38 overall). Montes is built on 70-grade power on the STS scale, and his projected peak line shows it: .254/.349/.509 with 34 homers and a 137.3 wRC+.

Rainiel Rodriguez (STL, C) is third, and at 19 he carries 5.2 Peak WAR (No. 44 overall), the highest WAR anywhere in the top 100. STS grades both his hit and power at 60, and the projected peak line backs that up: .278/.359/.497 with 28 homers and a 137.9 wRC+.

Eli Willits (WSN, SS) is the youngest of the top five at 18, and his 4.6 Peak WAR (No. 48 overall) is the 2nd-best in the top 100. His game runs on 70-grade speed on the STS scale, which shows up as 39 projected steals alongside a .258/.358/.433 line, 18 homers and a 123.1 wRC+.

Anthony Eyanson (BAL, SP) rounds out the top five at age 21 with 4.0 Peak WAR (No. 59 overall). OOPSY projects a 3.32 ERA, 148 strikeouts in 132 innings and a 1.28 WHIP at his peak.

River Ryan Makes the Month’s Big Move

Nobody in the top 100 moved in the past week, so these are the biggest prospect rank changes over the last 30 days.

Risers (30-day prospect rank change)

• River Ryan (DET, SP, 27): up 38 to No. 48, 3.1 Peak WAR
• Ethan Salas (SDP, C, 20): up 8 to No. 60, 3.4 Peak WAR
• Devin Fitz-Gerald (WSN, 2B, 20): up 3 to No. 96, 2.5 Peak WAR
• Michael Arroyo (SEA, LF, 21): up 2 to No. 19, 3.4 Peak WAR
• Robby Snelling (MIA, SP, 22): up 2 to No. 29, 3.0 Peak WAR

Fallers (30-day prospect rank change)

• Bo Davidson (SFG, CF, 23): down 3 to No. 74, 2.3 Peak WAR
• Kaelen Culpepper (MIN, SS, 23): down 2 to No. 58, 3.3 Peak WAR
• Caleb Bonemer (CHW, 3B, 20): down 1 to No. 7, 4.2 Peak WAR
• Theo Gillen (TBR, CF, 20): down 1 to No. 11, 3.8 Peak WAR
• Jesus Made (MIL, SS, 19): down 1 to No. 20, 4.0 Peak WAR

River Ryan’s 38-spot jump to No. 48 dwarfs every other move on the board; the next-biggest climb is Ethan Salas at 8 spots. Ryan is a name to keep on the radar in deeper leagues. The fallers list is mild by comparison. Nobody dropped more than Bo Davidson’s 3 spots, and a slip that small is not a reason to sell on its own.

Four Young Bats to Stash

These four sit outside the top 10, are 20 or younger and have not debuted, yet each projects for at least 3.9 Peak WAR. The picks come from Peak WAR, age and STS tool grades.

Franklin Arias (BOS, SS, age 20). Arias ranks No. 21, but his 4.4 Peak WAR matches Kade Anderson’s and is 3rd among the top 100. A 70-grade hit tool on the STS scale drives a projected .284/.348/.466 line with 22 homers and a 125.7 wRC+.

Leo De Vries (ATH, SS, age 19). The No. 16 prospect carries 4.0 Peak WAR, 10th in the top 100, with a 60-grade hit tool. He adds some speed to the profile, with a projected .258/.341/.449 line, 22 homers, 19 steals and a 120.3 wRC+.

Franklin Primera (BOS, C, age 19). Arias’s organization-mate ranks No. 27 with 3.9 Peak WAR, 15th in the top 100. A 60-grade hit tool supports a projected .269/.355/.442 line with 21 homers and a 123.9 wRC+.

Alfredo Duno (CIN, C, age 20). Duno is the deepest name here at No. 34, yet his 4.0 Peak WAR ranks 8th in the top 100, the widest gap of the four between rank and projection. STS grades his hit and power at 55, and OOPSY projects .253/.348/.437 with 21 homers and a 120.0 wRC+.

Spotlight: Where the Power Lives

Eighteen of the top 100 carry a power grade of 60 or better on the STS scale. Three of them reach 70: Lazaro Montes (3.9 Peak WAR), Andrew Fischer (3.4) and Joshua Baez (3.1). Montes is the only one of the three in the top five, and the two highest Peak WAR marks on the board belong to Rodriguez (60 hit, 60 power) and Willits (70 speed). Big power alone doesn’t top this board.
