The Royals Keep Minor League Awards: Northwest Arkansas Naturals

While the Storm Chasers weren't very good in 2026, people expected them to be mediocre in the spring. After all, it's hard for a Triple-A team to generate much buzz when it's composed mostly of Double-A players and veterans trying to get one last chance in the Big Leagues.

The Naturals, on the other hand, had loftier expectations.

While they weren't exactly "prospect flush" compared to High-A Quad Cities and Low-A Columbia, they featured some prospects expected to take the appropriate developmental steps, with an MLB debut on the near horizon.

Unfortunately, more top prospects disappointed in Northwest Arkansas than surprised. 

Shortstop Daniel Vazquez was supposed to build on a strong Arizona Fall League campaign and Spring Training, but only hit .246 with a .643 OPS in 451 at-bats (he fell out of our Top 20 at Royals Keep). Pitchers Drew Beam, Frank Mozzicato, and Felix Arronde were expected to matriculate to Triple-A or even the Majors this year with solid campaigns in Northwest Arkansas. However, none of these pitchers posted an ERA under 6.49, and they seemed primed to repeat at Double-A in 2027.

The Naturals prospects tended to underwhelm, and their 57-79 record reflected that. They finished only ahead of the Wichita Wind Surge (Twins), who were last in the Texas League North division with a 55-81 record. While it's nice that Northwest Arkansas didn't finish in the cellar, they never were in postseason contention at any point in 2026.

Nonetheless, some key prospects took steps forward in 2026, with four in particular standing out. As in our Omaha write-up, we will highlight the Hitter of the Year, Pitcher of the Year, Most Intriguing Prospect, and Biggest Riser from Northwest Arkansas this season. 

Hitter of the Year: Carson Roccaforte, OF

The Naturals were carried primarily by Roccaforte, our No. 9 prospect at Royals Keep, who may be pushing for a starting outfield spot on Opening Day (especially if Kyle Isbel cannot bounce back after a down 2026). 

In 45 games in 2025 with the Naturals, the former 2023 Competitive Round pick slashed .290/.387/.475 with an .862 OPS in 212 plate appearances. He also hit five home runs, scored 32 runs, drove in 29, and stole 10 bases. Thus, Roccaforte already had a foundation to succeed in Double-A in 2026.

Despite loftier expectations, Roccaforte continued to mash with the Naturals in 2026.

In 504 plate appearances in Northwest Arkansas, the 24-year-old outfielder slashed .251/.333/.523 with an .856 OPS. While the batting average and OBP went down, the power skyrocketed. That is shown not just by his improved slugging, but by his 30 home runs in Double-A. He also stole 21 bases, making him a true 20-20 threat in the Naturals lineup.

As a result, Roccaforte earned a promotion to Omaha in mid-August, and he seemed to do even better in Triple-A.

He slashed .282/.362/.500 with an .862 OPS in 118 plate appearances with the Storm Chasers. He also hit five home runs, drove in 16 RBI, and stole 11 bases on 11 attempts (much more efficient than his 21 for 38 mark in Northwest Arkansas). By the end of 2026, Roccaforte became one of the rare members of the 30-30 club in Minor League history (he's the first to accomplish such a feat since 2023).

With the Storm Chasers, Roccaforte still displayed strikeout (15th percentile K%) and whiff (10th percentile whiff%) issues, two things that have dogged him as a prospect since his days in Columbia. While the percentiles weren't as bad in Northwest Arkansas, he still rated on the lower end of the Texas League in both categories.

Conversely, his power and ability to pull the ball are excellent, as shown in his Statcast percentiles below via TJ Stats. 

Isbel is coming off a rough season, hitting .224 with a .591 OPS in 323 plate appearances for the Royals last season. Over his MLB career, Isbel has never hit the double-digit HR mark in a single season, and his OPS hasn't been above .700 since his rookie year (.771), when he played 28 games. 

Looking at his percentiles, Roccaforte could offer a better profile than Isbel at the MLB level, especially if his power translates from Triple-A. 

With Royals President JJ Picollo claiming that Kansas City needs to upgrade CF this offseason, it's possible that Roccaforte can be the solution in some form, maybe an everyday one if he can lower the strikeouts and whiffs just a bit over the next year. 

Pitcher of the Year: Hunter Patteson, LHP

The Naturals didn't get much dependable starting pitching in 2026. As noted before, Beam, Mozzicato, and Arronde, three pitchers expected to carry the Northwest Arkansas rotation, struggled mightily this season, which contributed to the club's poor record overall.

However, one starting pitcher who held his own was Patterson, who posted a 4.52 ERA and 1.37 WHIP in 99.2 IP with the Naturals this season.

Patteson didn't overwhelm hitters with elite stuff or movement. A fifth-round pick in the 2022 MLB Draft out of Central Florida, the lefty lived on throwing strikes (59th  percentile zone rate) and generating chase (58th percentile). While the chases didn't lead to many whiffs (20th percentile whiff%) or strikeouts (28th percentile K%), he kept the ball in the yard and generated plenty of outs in the field, both groundball and flyball. 

As a result of this strong, efficient approach, Patteson ranked in the top of the Texas League in ERA and BAA (batting average against) and was named the Naturals' Pitcher of the Month in both June and July. 

Because of his strong performance with the Naturals, Patteson earned a promotion to Omaha at the end of the season. The 26-year-old held his own, posting 1.96 ERA and 1.69 WHIP in 18.1 IP.

Much like his numbers in Double-A, the underlying data was a little more skeptical of Patteson with the Storm Chasers. His FIP was higher at 4.35, his K% was only 16.5%, and his K-BB% was 7.1%. Add a GB% of 37.5%, and it doesn't seem like Patteson has the right recipe to succeed at the MLB level. 

Furthermore, his TJ Stuff+ metrics weren't exactly impressive, as evidenced in the TJ Stuff+ season pitching summary below. 

Overall, Patterson posted a 90 TJ Stuff+ with a 22.2% chase rate, 17.7% whiff rate, and 46.6% zone rate. On a positive note, he did a great job minimizing hard contact in Omaha, as evidenced by his .311 xwOBACON. Patteson's best offering was his slider, which generated a 94 TJ Stuff+, 30.8% whiff rate, and .282 xwOBACON.

The former Central Florida product shares physical similarities with Daniel Lynch IV, though Patteson's stuff pales in comparison. However, like Lynch, a move to the bullpen could help Patteson's pitch mix and stuff play up more.

For an organization lacking lefty arms out of the bullpen, Patteson could find a niche as a lefty reliever in 2027 or 2028 if he can slightly improve his pitch quality. 

Most Intriguing Prospect: Hunter Owen, LHP

Owen made 17 starts and pitched 98 innings overall between Double-A and Triple-A this season. With the Naturals, he pitched 94 innings and posted a 5.94 ERA. Safe to say, based solely on ERA, Owen didn't appear to be an impressive pitching prospect. 

However, when looking deeper into his profile, Owen is more intriguing and could be an arm who could matriculate to the Royals bullpen sooner than fans may think. 

With the Naturals, the former Vandy product generated a 14.4% SwStr% (66th percentile), 32% O-Swing% (77th percentile), 25.1% K% (57th percentile), and only a 9.1% BB% (61st percentile). The CSW could've been better (44th percentile), and he allowed too many fly balls (10th percentile GB%), but these metrics and his 4.56 FIP showed that Owen was a better pitcher than his ERA indicated. 

The lefty particularly dominated in August, striking out 45 batters that month, an MiLB high.  

Owen had a cup of coffee in Omaha, making three relief appearances. In four innings of work, he generated ground balls at a high rate (57.1% GB%) and posted a solid K-BB% (14.3%). Overall, the stuff metrics weren't great, though his slider was a premium pitch in Omaha. 

Owen's slider had a 104 TJ Stuff+ with a 64.9% zone rate. His four-seamer, though lacking stuff (89), did generate above-average chase (28.6%) and xwOBACON (.251). A move to relief could help his four-seamer tick up in velocity and stuff, which in turn could help the other three offerings in his arsenal. 

The Royals will likely move Owen to the bullpen to fast-track him to Kansas City. Can his stuff improve in a relief role? If so, Owen may be the biggest sleeper in the upper Minors of the Royals' farm system pitching-wise, and he could make a push for a spot on Opening Day, depending on how Spring Training goes. 

Biggest Riser: Luke Pelzer, OF

When looking at hitting prospects, sometimes it's important to find guys who do all the little things right, even if they don't have the big tools. Steven Kwan is an example of this in Cleveland, and Nicky Lopez was one for the Royals (though his success was more fleeting). 

Pelzer may be the next prospect in this mold to make his way to the Majors, even if his tools may not impress prospect experts and scouts. 

Drafted in 2025 in the 17th round out of the University of Illinois-Chicago (a mid-major school), Pelzer has done nothing but hit, which has helped him move up quickly in the Royals' farm system. 

Pelzer began the year in High-A Quad Cities and slashed .337/.404/.506 with a .910 OPS in 295 plate appearances. While he hit only four home runs, he hit 18 doubles, scored 45 runs, drove in 59 RBI, and stole 28 bases on 32 attempts. 

Though he didn't have traditional home-run power, the 23-year-old could go yard from time to time, as evidenced by this grand slam in July below. 

After a strong performance with the River Bandits, Pelzer earned a promotion to Northwest Arkansas in late July. In 42 games with the Naturals, the outfielder didn't skip a beat.

He slashed .337/.414/.405 with an .819 OPS in 186 plate appearances. He dropped his whiff and K rates in Northwest Arkansas, while increasing his walks and Z-Contact%. He also hit seven doubles, two triples, scored 31 runs, drove in 10, stole 14, and had a partridge in a pear tree (scratch that last one). 

Yes, Pelzer doesn't hit home runs. He had zero in Northwest Arkansas, and it doesn't seem likely that he will ever hit double digits in a season at the Major League level. That's a knock against him.

However, he does everything else right offensively. He's the kind of hitter that teams like Cleveland and Milwaukee produce. It would be nice if Pelzer could start a similar trend for the Royals. 

Kansas City could use a hitter like Pelzer in the bottom of the order, especially in the No. 8 or 9 spot. He is the kind of hitter who can extend innings and set things up for Carter Jensen and Bobby Witt Jr. at the top of the Royals lineup.

It would not be surprising to see Pelzer get that opportunity in the second half of 2027 or by Opening Day in 2028.
