Rusney Castillo will make his Major League debut for the Boston Red Sox on Wednesday against the Pittsburgh Pirates.

"He's an electric player with a lot of skills -- he's explosive, quick-twitch," John Farrell said. "We're looking forward to seeing him in this park."

Castillo signed a seven-year, $72.5 million deal with the Red Sox on Aug. 23 and progressed through three levels of the Red Sox minor-league system after making his pro debut six days later.
