In the world of sports, it's easy to get caught up in the hype of a single month's performance, but it's crucial to dig deeper and assess the sustainability of these trends. This week, we're taking a closer look at three players who have been making waves: Jonathan Aranda, Brooks Lee, and Spencer Arrighetti. While each of them has shown impressive results, the question remains: are they legit, or is it just a flash in the pan? Let's dive in and explore the nuances of their performances, offering a critical perspective on their potential for the future.
Jonathan Aranda: The Rising Star
Jonathan Aranda, a first baseman for the Tampa Bay Rays, has been on a tear in May, slashing an impressive .374/.464/.560 with 17 runs, four home runs, and 18 RBI in 26 games. This surge in production is particularly notable given his struggles in April, where he hit just .220. The increased power is a welcome sight, especially considering his xSLG of .515 in 2025, which was already better than his .489 SLG. Aranda's quality of contact metrics are also above-average, with a 47.7% hard-hit rate and a 40.4% launch angle sweet-spot rate, along with a robust 14.1% walk rate.
What makes Aranda's performance even more intriguing is his seamless transition from last season. His underlying metrics were already off the charts in 2025, and he's carried that momentum into this year. This consistency is a testament to his skill and potential, making him a good bet for a great batting average and an even better option in OBP leagues. The weakness of a lack of home runs for a typical first baseman has been addressed, as Aranda is now on pace for 30 home runs.
However, it's essential to consider the broader context. Aranda's success is not just a result of his hitting prowess; it's also due to the Rays' willingness to play him every day. This regular playing time has allowed him to develop his skills and build confidence, which is crucial for any player's growth. Personally, I think Aranda's performance is a clear indication of his legitimacy as a fantasy contributor. His ability to maintain high-quality contact and power is a significant step forward, and his consistency is a sign of his potential for long-term success.
Brooks Lee: The Power Hitter
Brooks Lee, a versatile player for the Minnesota Twins, has been on a hot streak in May, batting .286 with seven runs, three home runs, and 10 RBI in the past 14 days. This performance has made him a top-8 option at second base, third base, and shortstop during that span. On the season, Lee is slashing .256/.314/.429 with a .328 wOBA, all of which are career highs. His 18 extra-base hits on the season are over halfway to the 32 he collected in 2025.
However, the underlying metrics for Lee's performance are less impressive. All of his quality of contact metrics fall in the bottom 20% of the league, which is not a good omen for his increased power numbers to continue. The bright spots for Lee are his 17.8% strikeout rate and 18.2% pull air rate, but these numbers aren't elite enough to completely override the general lack of pop. In my opinion, Lee's performance is a clear indication that his power is not sustainable, and his quality of contact metrics are too similar to last year to expect any consistent power to stick.
While Lee may not be a legit power hitter, he is still a valuable asset in deep leagues. His triple eligibility and flexibility make him a helpful asset in deep 15+ team Roto leagues with middle and corner infield spots. However, in shallower leagues, he should be considered nothing more than a hot-hand streaming play if you're desperate.
Spencer Arrighetti: The Breakout Pitcher
Spencer Arrighetti, a pitcher for the Houston Astros, has been on a tear since making his season debut on April 15. He's yet to allow more than two runs in a start through eight outings, and seven of them were one run or less. Over that span, he's posted a 1.34 ERA, 1.13 WHIP, 43 strikeouts, and 26 walks in 47 innings. While this is a huge breakout for someone with a career ERA of 4.00 and a WHIP of 1.35, it's not the first time Arrighetti has displayed a run of dominance.
In August and September of 2024, Arrighetti posted a 2.72 ERA and a 1.17 WHIP with an elite strikeout rate of 31.0% and a walk rate of 8.3%. This made him a trendy sleeper pick heading into 2025, where he ultimately underperformed and spent most of the season injured. While it may look like he's finally delivering on that breakout upside, it's essential to note that there are still some major flaws present now that weren't there for his hot streak in 2024.
Arrighetti's strikeout rate is a middling 21.7%, and his walk rate ranks in the 11th percentile at 13.1%, which is not a combination that typically leads to success at the major league level. On top of that, he possesses a 36.4% groundball rate, which is not good considering how few hitters he is striking out. That's a lot of balls put into play in the air, and at the moment, he's surviving by maintaining a 29.8% hard-hit rate, which ranks in the 91st percentile. In my opinion, Arrighetti has shown enough bright spots to give me confidence that he won't revert to being a 5.35 ERA guy like he was last season. However, he's walked four or more batters in five of his eight outings this season, and it's not sustainable to leave them on base as often as he is. This isn't a step forward into being an elite fantasy option, and regression is certainly coming, but not enough that he'll turn back into waiver wire fodder.
Conclusion
In conclusion, the performances of Jonathan Aranda, Brooks Lee, and Spencer Arrighetti are intriguing, but they are not without their nuances. Aranda's consistent performance and power surge make him a legit fantasy contributor, while Lee's power is not sustainable and should be considered a hot-hand streaming play. Arrighetti, on the other hand, has shown enough bright spots to give him confidence, but his flaws are still present, and regression is likely. As we move forward, it will be crucial to monitor these players' performances and assess their long-term potential, keeping in mind the broader context of their skills and the challenges they face.
