Athletics Community Prospect List: Barnett Finds His Spot At #11

*In an effort to make the nomination voting easier for everyone, I will comment, “NOMINATIONS”, and you may reply to that with your picks and upvote the player you’d like to see on the next nominee list.

After just barely losing last round to outfielder Devin Taylor, right-handed starter prospect Mason Barnett was the clear winner for the 11th-best prospect in the A’s system as voted on by A’s fans. Barnett, the headline return piece from Kansas City the A’s got back in exchange for Lucas Erceg, made his big league debut this past season, getting a quick cup of coffee in the big leagues. The righty didn’t look all that great in Triple-A this past season, his first at that level, and he predictably struggled against higher competition in the big leagues. The team will continue letting him develop in Triple-A to open the year but he’s likely one of the first callups when an injury inevitably pops up. We’ll all be hoping he takes advantage of that chance when it comes.

The next nominee joining the remaining four is right-handed pitcher Gunnar Hoglund. Another far ago top trade return, Hoglund’s professional career has been dogged by seemingly never-ending injuries. After four years climbing the minor league ladder he finally made it to the big leagues this past season after dominating at Triple-A to open the year. And he looked good over his first couple of starts in the big leagues. Unfortunately the injury bug seemed to crop up again as he struggled hard in his final few starts with the A’s, The righty would undergo hip surgery in mid-June, prematurely ending his rookie season. There haven’t been any reports of any sort of setbacks but we’ll be finding out soon if there have been since everyone is reporting in for duty.

A’s fans top prospects, ranked:

The voting continues! Who will be voted as the 12th-best prospect in the A’s system? 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:

Tommy White, 3B

Expected level: Double-A | Age: 22

2025 stats (A+/AA): 395 PA, .275/.334/.439, 23 doubles, 0 triples, 12 HR, 51 RBI, 29 BB, 54 K, 3 SB

MLB Pipeline grades and scouting report:

White’s right-handed power is legitimate and he can hit the ball a long way to all fields thanks to his strength and bat speed. He might be known for his home run totals but he’s a better overall hitter than people think, finding the barrel consistently and limiting strikeouts. His knack for contact can lead to him expanding his strike zone, but he doesn’t swing and miss very often.

It will be White’s bat that carries him to the big leagues. He’s a well-below-average runner who likely lacks the range and tools to stick at third base, where he toiled as a sophomore and junior, earning praise for playing through a shoulder injury at LSU in 2023. He’s likely headed to first base long term, which could give the A’s a glut of serious offensive talent between him and first-rounder Nick Kurtz.

Shotaro Morii, SS/RHP

Expected level: Low-A | Age: 19

2025 stats (Rookie Affiliate): 188 PA, .258/.399/.384, 8 doubles, 1 triple, 3 HR, 27 RBI, 36 BB, 47 K, 4 SB

MLB Pipeline grades and scouting report:

At the plate, Morii features a smooth left-handed swing with tremendous balance. His power stands out, as he clubbed 45 home runs as a high schooler. He is considered an advanced hitter with good barrel control. On the mound, his fastball has been clocked as high as 95 mph and sits around 92-93. He also brings a splitter with nasty movement, a true 12-to-6 curveball and a tighter slider with solid bite and depth, though that offering will probably require some fine-tuning. Having only been pitching with regularity for less than two years, Morii’s arm is relatively fresh as he enters the organization.

Morii’s high-octane throwing arm plays well at shortstop, but some evaluators see a possibility of moving to third base as his 6-foot-1 frame fills out. While scouts see Morii’s long-term future in the batter’s box, the A’s plan on giving him every opportunity to succeed as a two-way player, with excitement already building over his impressive physical traits and desire to become one of the next great players out of Japan.

Henry Baez, RHP

Expected level: Triple-A | Age: 23

2025 stats (Double-A): 2.39 ERA, 23 starts, 109 IP, 100 K, 35 BB, 3 HR, 3.19 FIP

MLB Pipeline grades and scouting report:

Scouting grades: Fastball: 55 | Curveball: 55 | Changeup: 45 | Control: 50 | Overall: 45

The 6-foot-3 right-hander has gained velocity steadily in his years as a pro and has touched as high as 99 mph this season. He typically sits around 94 mph, working north-south with the pitch while getting most of his whiffs up and to the armside. He played off that with a 76-79 mph curveball that could have more slurvish tendencies, but at its best, it snapped downward to fool batters sitting on the high heat and it had produced a 47 percent miss rate at the time of the trade. He also utilizes an 83-86 mph split-change to miss bats, but it stands out more for its separation than movement profile.

Baez took a major jump in workload but didn’t let his control improvements suffer. That certainly helps his starting chances, as does his 50.1 percent ground-ball rate from 2024. He’s still only 22, but with his place on the roster now set, the A’s (never afraid to move guys quickly) could try to see what it looks like in the big leagues in a relief role to ease him in.

Gunnar Hoglund, RHP

Expected level: Triple-A/Majors | Age: 26

2025 stats (Triple-A): 2.43 ERA, 6 starts, 29 2/3 IP, 30 K, 7 BB, 3 HR, 4.17 FIP

2025 stats (Majors): 6.40 ERA, 6 starts, 32 1/3 IP, 23 K, 11 BB, 10 HR, 6.75 FIP

MLB Pipeline grades and scouting report:

Scouting grades: Fastball: 45 | Slider: 55 | Changeup: 50 | Control: 60 | Overall: 45

Though Hoglund may never get back the electric stuff he possessed earlier in his career, the A’s were encouraged to see his fastball velocity tick back up to the low-90s. He has also experimented with adding a two-seamer and cutter. His low-80s slider now features more sweeping action and works as his main secondary pitch. He has also improved his low-80s changeup, creating a solid three-pitch mix that is enhanced by a strong ability to consistently throw strikes.

Now three years removed from Tommy John, the A’s are hopeful that Hoglund can develop into a solid back-end rotation piece, especially if he can successfully develop a fourth pitch. The Florida native was regularly going deep into starts in his big league cameo (6.40 ERA with 23 strikeouts to 11 walks across 32 1/3 innings) before going down with the injury and is expected to make a full recovery before the 2026 season.

Cole Miller, RHP

Expected level: Single-A | Age: 20

2025 stats (ROK, Single-A): 1.90 ERA, 12 starts (15 appearances), 52 IP, 45 K, 11 BB, 1 HR, 3.38 FIP

MLB Pipeline grades and scouting report:

Scouting grades: Fastball: 55 | Slider: 50 | Changeup: 50 | Control: 45 | Overall: 40

The A’s were working on some mechanical adjustments with Miller prior to his injury. His electric fastball ticked up to 96 mph in high school and displayed excellent movement down in the zone. The mid-80s slider is a hard breaker and was showing signs of improvement. His low-80s changeup showed some potential as an average third pitch.

There was real excitement within the organization for Miller’s professional debut. His three-pitch mix and large 6-foot-6 frame give off the potential of a workhorse-type starting pitcher in the big leagues. The A’s also loved the competitiveness they saw from him on the mound while scouting him. After an unfortunate delay, he finally got his first opportunity to make an impression this summer.
