Chris's fantasy baseball prospects to stash list for Week 12 of 2025. HIs top MLB prospects and rookie sleepers to make fantasy impacts this year when called up.
Welcome, friends, to the 2025 MLB season, and my weekly article about fantasy baseball prospects to stash heading into Week 12. Who are the top prospects you need to know for redraft leagues? Last week, we nailed Ryan Ritter and Roman Anthony getting the call. We are running low on top prospects to get the call, but who could be next? Let's break down Brady House, Bubba Chandler, Jack Perkins, and Andrew Painter.
Winning in a fantasy baseball redraft league requires a nice blend of high-floor players and upside shots. While prospects present more risk in a one-year setting, such as a redraft league, they pay big dividends if they succeed. The reward could be huge if these players receive adequate playing time and perform well.
Throughout the season, there will be plenty of prospects who will get promoted and make an impact on their respective MLB teams and fantasy teams. Getting ahead of the curve on these players can pay huge dividends regarding FAAB bids. You can save money and have your league mates question how you are already in on that player so far in advance. Here are this week's fantasy baseball prospects to stash. These players can make a splash in redraft leagues for the remainder of the 2025 season and are expected to debut in the big leagues soon.

Brady House, 3B - Washington Nationals
How close are we getting to a House call-up to the Nationals? He continues to swing it well, and has taken a huge step forward at the plate in 2025, and is impressive in the field.
Sometimes, it feels like House has been around forever, so it is somewhat humbling to remember he turned 22 years old last week. His 2024 season was like much of his career, as we saw highs and lows. The good news is, for the first time in his career, Hosue stayed healthy and played 129 games.
So far in 2025, House has gotten results. His .298/.350/.517 slash is backed by good underlying data. The ground ball rate of 47 percent is still an issue, and he needs to show improvements in sweet-spot rate, meaning he will need to hit the ball at ideal launch angles more often.
House has always hit the ball hard, so it is not a surprise to see the impressive hard-hit rate of 45 percent, but his 109 mph 90th percentile exit velocity and 90.5 mph average exit velocity stand out. Despite the ground balls, House still hits the ball hard often enough to run a barrel rate near 11 percent.
The approach has been cleaned up a bit. Last year, House chased around 40 percent of pitches he saw out of the zone. This year, that number has dropped to 34 percent, and House is showing more aggression on pitches in the zone.
House still has talent, and if he can show just an average approach and contact skills, there are 30 home runs in the bat with a solid glove at third base. He should get the call soon.
Jack Perkins, RHP - Athletics
Perkins returned from injury at the beginning of May and struggled out of the gate. He has improved as the season has worn on and is coming off a 10-strikeout start. Despite a six-run blowup in May, Perkins has a 2.58 ERA and a 36.6 percent strikeout rate.
Perkins is armed with a big fastball that sits 96-98 mph. It is a high-riding pitch from a low release point, missing plenty of bats. Perkins can also mix in a running sinker on you as well to keep the ball on the ground.
The slider evolved into a sweeper in 2024, reaching mid-80s with high spin rates. It averages around ten inches of sweep with good depth as well. Perkins also mixes in an upper-80s changeup with good depth and arm-side movement.
Given the performance in Triple-A and the Athletics' skidding, it might not be long before we see Perkins in Sacramento. Perkins will need to be added to the 40-man this offseason, so we may see him added over the next several weeks.
Bubba Chandler, RHP - Pittsburgh Pirates
He pairs it with a changeup that tunnels well off the fastball and has excellent fading action, sitting north of 90 mph. It averages 17 inches of arm-side fade with a late tumbling action. The slider could end up being a 70-grade pitch if he harnesses the command of it somewhat, as it sits anywhere from 87-90 with a strong gyro shape. Chandler has added a new curveball this year that sits around 83 mph with more depth than the slider.
Andrew Painter, RHP - Philadelphia Phillies
Painter's last two starts don't give a ton of confidence that he is ready to be in the majors. It may not even be before the All-Star break before we see him, but that does not mean we are not reaching stash territory. The good news is, even in Painter's recent start, which was bad, he faced 24 batters, the most he has faced in a game since September 2022. Building up innings and improving his command are the biggest hurdles at this point.
Painter's fastball has sat at 97 mph and touched 100 mph. The velocity is fully back, and Painter's fastball averages around 18 inches of IVB from a 6'6" release height. The command will only get better with the pitch, but it already looks like the plus offering it was pre-surgery.
Painter's cutter has been his most-used secondary pitch. It is around 90 mph with good spin and carry, and misses bats at an impressive clip for a cutter. The slider is around 86 mph with more depth and nine inches of sweep and plays well off the cutter.
The curveball has remained strong, sitting between 80-82 mph. It has shown depth and sweeping action, averaging negative three inches of IVB and 10 inches of sweeping action. Painter has thrown his changeup sparingly this year as a distant fifth pitch. It sits around 90 mph with carry and 12 inches of fading action.
