San Jose Giants’ 19‑year‑old switch‑hitter Jhonny Level vaulted to the top of the MLB Rookie Power Rankings on May 19 after a historic two‑homer outing that showcased power from both sides of the plate. The performance came in a 17‑4 win over Stockton at Excite Ballpark and marked Level’s first multi‑homer game as a full‑season affiliate.
San Jose Giants are rebuilding at the major‑league level, and the organization hopes Level can become a cornerstone of that effort. The club’s front office brass believes the numbers reveal a ceiling that could translate quickly to higher levels, and they have already begun reshaping the farm system to give the teen more opportunities.
Level’s surge arrives as the Giants’ Single‑A club looks to develop a pipeline of power hitters for a rebuilding major‑league roster. His blend of raw strength and plate discipline positions him as a potential cornerstone for San Francisco’s future lineup.
San Jose Giants have long relied on veteran mentors to guide young talent, and this season’s coaching staff was praised for accelerating Level’s development. The team’s hitting coach, Marco Alvarez, said the player’s ability to drive the ball from both sides forces pitchers to rethink their approach, a rare skill at this level. The club’s scouting director, Carlos Pérez, noted that Level’s swing mechanics were refined during winter workouts, a factor that helped him smash a 415‑foot right‑handed blast.
What does Level’s recent game reveal about his rookie power?
Level produced a three‑hit, six‑RBI effort, including a three‑run shot from the right side against southpaw Alex Barr, demonstrating genuine switch‑hit potency. The 19‑year‑old’s ability to generate power from both flanks is rare at Single‑A, suggesting a ceiling that could translate quickly to higher levels.
How does this performance fit into his broader development?
Level’s two‑homer night was his third career multi‑homer game, but the first where he homered from each side in a single contest. Earlier multi‑homer outings occurred on June 27, 2024, in the Dominican Summer League and June 19, 2024, in the Arizona Complex League, where he also posted a career‑high seven RBIs. In his stateside debut last season, he ranked second in total bases (108) and third in homers (nine) in the Arizona Complex League, underscoring a consistent power trajectory.
Key Developments
- Level’s six RBIs set a season‑high for the Single‑A Giants, surpassing his previous best of five in 2025.
- The game marked the first time a full‑season affiliate recorded a switch‑hitter’s two‑homer game from both sides, a milestone noted by Giants scouting director Carlos Pérez.
- Level’s right‑handed three‑run blast traveled an estimated 415 feet, according to Statcast data released by MLB.com.
- His left‑handed solo homer came on an 84‑mph fastball, highlighting his ability to drive off‑speed pitches.
- Following the game, the Giants promoted Level to High‑A, accelerating his path toward a potential 2027 major‑league debut.
Impact and what’s next for the Giants’ rookie surge
Level’s breakout performance forces the Giants’ front office to re‑evaluate his timeline; a rapid promotion could see him in spring training next year, providing a high‑impact bat for a club seeking offensive depth. Fantasy baseball owners are already flagging him as a high‑upside waiver‑wire candidate, especially in deeper leagues where switch‑hit power is scarce. However, scouts caution that his home‑run rate may normalize as he faces more advanced pitching, a typical adjustment for teenage power hitters.
What were Jhonny Level’s OPS+ numbers in the Arizona Complex League?
Level posted a 152 OPS+ during his 2024 Arizona Complex League season, indicating his on‑base plus slugging was 52% better than league average.
How does Level’s power compare to other Giants prospects?
Among Giants’ top ten prospects, Level ranks third in home‑run frequency, trailing only outfielders Alex Rodriguez and Marco Sanchez, who logged 12 and 10 homers respectively in 2025.
When is the Giants likely to call up Level to the majors?
Analysts project a September call‑up in 2027 if Level maintains a slugging rate above .550 at High‑A and Double‑A, aligning with the organization’s typical promotion schedule for power‑first prospects (general knowledge).
