Spencer Jones has dominated since his June 27 promotion, hitting .400 with 13 home runs, including a three-homer game, in 19 Triple-A games.

The Yankees are only willing to trade their mashing prospect for Pirates ace — and arguably the industry’s most desirable pitching trade asset — Paul Skenes, and would not include Jones in trade talks with the Marlins for former NL Cy Young winner Sandy Alcantara, according to The Post’s Jon Heyman.

Jones is ranked behind infielder George Lombard Jr., as well as right-handed pitchers Carlos Lagrange and Cam Schlittler, on the Yankees' prospect rankings, via MLB.com. Schlittler is with the big-league club, while Lombard and Lagrange are in Double-A.
