Team Italy’s 2026 World Baseball Classic roster includes several current MLB players and many others in MLB organizations who qualify via Italian heritage or citizenship.

Key current MLB players on Team Italy

These are the headline MLB names confirmed or reported as part of (or leading) the 2026 Team Italy WBC squad:

  • Aaron Nola – RHP, Philadelphia Phillies (ace starter, first WBC for Italy).
  • Michael Lorenzen – RHP, Colorado Rockies (veteran starter/reliever, former All‑Star).
  • Vinnie Pasquantino – 1B, Kansas City Royals (middle‑of‑the‑order slugger, played for Italy in 2023 WBC and returns in 2026).
  • Jac Caglianone – OF/1B, Kansas City Royals organization, reached MLB and brings left‑handed power.
  • Dominic Canzone – OF, Seattle Mariners (left‑handed bat with power).
  • Miles Mastrobuoni – INF, Seattle Mariners (versatile utility infielder).
  • Jon Berti – INF/UT, MLB veteran known for speed and versatility.

In addition, Italy’s roster is heavily filled out with players who are on 40‑man rosters or in upper‑level affiliates (AA/AAA) for MLB clubs, which is why coverage often notes that Italy has “a roster of mostly American MLB players” or MLB‑affiliated talent.

MLB‑affiliated position players

These players are either currently in MLB or in MLB farm systems but are listed on Italy’s 2026 WBC roster:

  • Vinnie Pasquantino – 1B, Royals (MLB).
  • Jac Caglianone – OF/1B, Royals system, power bat, expected MLB impact.
  • Dominic Canzone – OF, Mariners (MLB).
  • Miles Mastrobuoni – INF, Mariners (MLB).
  • Thomas Saggese – INF, St. Louis Cardinals organization (top infield prospect, upper minors/MLB bubble).
  • Sam Antonacci – INF, Chicago White Sox (AA Birmingham Barons).
  • Zach Dezenzo – INF, Houston Astros organization.
  • Andrew Fischer – INF, Milwaukee Brewers organization (A+ level).
  • Jakob Marsee – OF, Miami Marlins organization.
  • Nick Morabito – OF, New York Mets organization (AA).
  • Dante Nori – OF, Philadelphia Phillies organization (AA).

These names sit alongside Italy‑based or independent players who round out the lineup and bench.

MLB‑affiliated pitchers

On the mound, Italy leans on established MLB arms plus prospects from MLB systems:

  • Aaron Nola – RHP, Phillies (ace, All‑Star, postseason veteran).
  • Michael Lorenzen – RHP, Rockies (starter/reliever, ex‑All‑Star).
  • Matt Festa – RHP, Cleveland Guardians reliever.
  • Adam Ottavino – RHP, long‑time MLB reliever, free agent but with 15 years of MLB experience.
  • Greg Weissert – RHP, Boston Red Sox organization (MLB/AAA shuttle reliever).

Italy also has pitchers developed in Italy or in minors who are not currently big‑league regulars (for example Gabriele Quattrini from Serie A, plus other MLB‑pipeline arms discussed in WBC previews), but the names above are the most clearly MLB‑connected.
