The second round was a much closer race this time around between left-handers Jamie Arnold and Gage Jump. Arnold came out on top though with roughly 60% of the vote, taking the second overall spot in this year’s Community Prospect List. The 11th overall pick in the draft just this past year, Arnold is further away compared to the team’s other top prospects but he could end up being the best of the bunch. The side-armer has drawn plenty of comparisons to another stud lefty in Chris Sale and the A’s would be ecstatic to see Arnold take that same career trajectory. The 21-year-old has yet to get his professional career officially started but that should be coming soon, likely at Single-A with a quick promotion on the table.
The next nominee to join the list will be left-hander Wei-En Lin. The Taiwanese lefty was previously ranked fairly moderately last year but has absolutely shot up the ranks of the A’s system thanks to a vast repertoire that looks like it could propel him into the starting pitching mix near the end of the year. Lin could be yet another left-hander that the A’s develop alongside Arnold and Jump, but will he be able to jump the line this coming year?
The process for this public vote is explained below. Please take a moment to read this before participating:
-
Please only vote for one. The player with the most votes at the end of voting will win the ranked spot. The remaining four players move on to the next ballot where they are joined by a new nominee.
-
In the comments, below the official voting, the community will nominate players to be put onto the ballot for the next round. The format for your comment should be “Nomination: Player Name”.
-
If a prospect is traded, his name will be crossed out, and all other players will be moved up a space. If a prospect is acquired, a special vote will be put up to determine where that player should rank.

The voting continues! Who will take third place? Here’s a quick rundown on each nominee— the scouting grades (on a 20-to-80 scale) and scouting reports come from MLB Pipeline.
Nominees on the current ballot:
Gage Jump, LHP
Expected level: Triple-A | Age 22
2025 stats (A+/AA): 3.28 ERA, 24 starts, 112 2/3 IP, 131 K, 34 BB, 7 HR, 2.96 FIP
MLB Pipeline grades and scouting report:
Scouting grades: Fastball: 55 | Curveball: 55 | Slider: 60 | Changeup: 50 | Control: 55 | Overall: 55
Jump’s fastball is difficult for opposing hitters to pick up with an arm angle that creates some deception. The heater sits about 92-94 mph and can reach up to 97 with good carry up in the zone. His upper-70s curveball has significant downer break, and his low-80s slider has cutting action. His fading low-80s changeup is used far less than his other three offerings.
Listed at 6-foot, Jump lacks the size of a typical starter, though his growth since the surgery and ability to generate his stuff with arm speed helps his potential outlook as a long-term starter. The ceiling of a mid-rotation starter is there, though some scouts believe he might be better suited in a bullpen role. To start out, the A’s will develop him as a starter and look to see him maintain good health and strike-throwing ability.
Henry Bolte, OF
Expected level: Triple-A | Age 22
2025 stats (AA/AAA): 488 PA, .284/.385/.427, 20 doubles, 6 triples, 9 HR, 56 RBI, 57 BB, 141 K, 44 SB
MLB Pipeline grades and scouting report:
Scouting grades: Hit: 45 | Power: 55 | Run: 65 | Arm: 50 | Field: 50 | Overall: 45
Bolte is a tooled-up athlete who continues to fill out his big 6-foot-3 frame. His impressive raw power continues to show up in the Minors, though there is still a real concern over his swing-and-miss and high strikeout rate as he continues to struggle with offspeed stuff out of the zone. The A’s have worked with him to revamp his swing in order to improve his bat path and cover more of the zone, which has produced slight improvements in those areas, though there is still plenty of work to be done.
Another shining tool for Bolte is his near-elite speed, which was on display last season as he swiped 46 bags. That speed also comes in handy on defense, combining that with a strong arm that makes him a solid outfielder at all three spots. Further refining is required, but he remains an exciting talent with a very high ceiling who continues to steadily advance through the system.
Braden Nett, RHP
Expected level: Triple-A | Age 23
2025 stats (AA): 3.75 ERA, 24 starts, 105 2/3 IP, 116 K, 48 BB, 8 HR, 3.77 FIP
MLB Pipeline grades and scouting report:
Scouting grades: Fastball: 55 | Curveball: 55 | Slider: 60 | Changeup: 50 | Control: 55 | Overall: 55
While working around the injuries, Nett has continued to show stellar velocity, touching as high as 99 mph in the Minor Leagues last season. He typically sits 95-97 mph and gets swing-and-miss up in the zone thanks to ample carry. He also throws a tight 81-84 mph slider that ran a 38 percent whiff rate in ’24 and a sharper 90-92 mph cutter that can catch hitters off guard. He’ll mix in an upper-70s curveball with more vertical drop and he’s scrapped a low-80s splitter in favor of a much more effective 88 mph kick-change that really neutralizes lefties.
Nett has some effort in his delivery, and the 2025 season (pre-trade) was the first time he’d posted a walk rate below 13 percent at any Minor League stop. Combine that with the early injury concerns, and it’s easy to think he could be a reliever eventually. But his arsenal is deep enough, and his stuff is promising enough — when combined with strides taken this season — to keep landing him in a starting role in the upper Minors.
Johenssy Colome, SS
Scouting grades: Hit: 55| Power: 65 | Run: 50 | Arm: 60 | Field: 55 | Overall: 60
It’s not often that teenage prospects launch home runs. But Colome has a tendency to get to that jumpy pop with frequency, consistently leveraging his swing well – so well in fact, that one evaluator mentioned the most recent occasion on which he saw an international prospect continually get to their launch point in such a manner was Vladimir Guerrero Jr. Colome is a right-handed hitter with explosive hands and a solid contact rate, although he has been known to be a tad aggressive in the box as a means of getting to said power.
Something of an athletic marvel at 6-foot-2 and 190 pounds at age 16, Colome is an agile athlete who shows a lot of lateral quickness. The fluidity of his movements and strong arm led to a Manny Machado comparison being hung on him defensively. Much like the seven-time All-Star, Colome may move off short as his frame fills out, but he’s a tremendously dedicated worker and has the feet, soft hands and instincts to stick at the premium position.
Wei-En Lin, LHP
Expected level: Double-A | Age 20
2025 stats (A, A+, AA): 3.72 ERA, 13 starts (26 appearances), 87 IP, 117 K, 22 BB, 9 HR, 3.77 FIP
MLB Pipeline grades and scouting report:
Scouting grades: Fastball: 50| Curveball: 50 | Slider: 45: 50 | Changeup: 50 | Field: 55 | Overall: 40
A 6-foot-2 left-hander, Lin has a combination of feel for as many as five pitches and projection to his frame. Right now his fastball averages just 91 mph, but it tops out at 95, and it’s easy to see that his frame has tremendous room to add good strength, with more consistent velocity to come. It already had the makings of a quality heater, thrown from around a 5.9-feet release height and with more than 18 inches of carry to it, helping it to miss a good amount of bats. His changeup has been his best secondary offering to date, with huge whiff rates during his debut. His short curve is his go-to breaking ball thus far, though he has a harder, shorter slider. He’ll also employ a splitter for another offspeed possibility.
It’s been a small sample size so far in his first full season, but Lin looks like he has the makings of being an extreme strike-thrower, showing particularly good command of his fastball and curve. If the teenaged southpaw is able to fill out and throw harder, the A’s could have a very interesting left-handed starting pitcher prospect on their hands.
