It didn’t take long for Rusney Castillo to go yard in the U.S.

The Cuban outfielder — who inked a seven-year, $72.5 million contract with the Boston Red Sox on Aug. 23 — sent the first pitch he saw during the first inning of the Triple-A National Championship in Charlotte, N.C., on Tuesday over the fence.

Castillo was batting .297 with four RBIs and six runs in 10 minor league games before the Pawtucket Red Sox’s contest against the Omaha Storm Chasers. Boston manager John Farrell said Castillo was “likely” to join the big league club Wednesday against the Pittsburgh Pirates.
