It’s been an up-and-down career for today’s prospect.

This is Blue Jays Nation’s annual Pre-Season Prospect Countdown, this time looking at the top 40 prospects in the organization. We’ll look at the player’s stats, my observations, and other publications&#8217; scouting reports if available.
Let’s take a look at our 24th-best prospect in the Toronto Blue Jays organization, Rainer Nuñez.

<h2>Getting to know Rainer Nuñez…</h2>
Position: First base
Bats: Right
Born: December 4, 2000
Acquired: 2017 International Free Agency
Previous ranking: Not ranked (35th in 2024’s pre-season ranking)
Signed during the 2017 International Free Agency period, Nuñez didn’t make his professional debut until 2018. After two mediocre seasons in rookie ball (84 wRC+ in 2018 and 55 wRC+ in 2019), Nuñez had a mini-breakout in 2021, slashing .273/.373/.477 with six home runs in 169 plate appearances.
Thanks to a strong start in Single-A where he slashed .299/.328/.482 with 15 home runs in 384 plate appearances in 2022, he ranked as our 22nd-best Blue Jays prospect in the mid-season update. Nuñez finished the season slashing .321/.379/.491 with four home runs in 116 plate appearances with the High-A Vancouver Canadians.
Moreover, he won the Florida State League batting title for his work in Single-A. With Estrellas Orientales of the Dominican Winter League, he slashed .263/.303/.445 with seven home runs in 145 plate appearances, leading the league in home runs and winning its Rookie of the Year award.
After a strong 2022, Nuñez ranked as our 16th-best prospect in the organization for the 2023 pre-season update. The first baseman repeated the High-A level to begin the 2023 season, slashing .309/.390/.446 with three home runs in 159 plate appearances. However, he struggled to adjust to Double-A batting when he was inevitably called up, slashing .224/.273/.352 with 10 home runs in 326 plate appearances for a 70 wRC+.
Nuñez had a much better 2024 season in Double-A, hence his ranking, as he slashed .275/.349/.416 with 12 home runs in 433 plate appearances. He also walked 10.2% of the time, well up from his 3.6 BB% in Single-A in 2022.
The 24-year-old’s calling card is his power. He produces some of the best exit velocities in the organization, but also drives the ball into the ground a lot (53.6 ground ball percentage in 2024). His hit tool isn’t bad though, hitting for a respectable average while being able to take a walk. Nuñez’s strikeout rate has crept up the higher he’s gotten in the minor leagues. As for his defence, he&#8217;s destined to play first base or designated hitter.
