12:46pm: Cuban outfielder Rusney Castillo’s showcase for Major League teams is tomorrow, but MLB.com’s Jesse Sanchez adds an interesting twist to the audition: the speedster will work out at both center field and at shortstop (Twitter link).

Previous reports have indicated that the Twins, Cubs, White Sox, Braves, Giants, Mariners, and Orioles would attend the showcase. Additionally, Marc Topkin of the Tampa Bay Times writes that the Rays will be in attendance, while Juan C. Rodriguez of the Miami Sun-Sentinel notes that the Marlins will be in attendance, and George A. King III of the New York Post adds the Yankees to the mix. Beyond that, Jon Heyman of CBS Sports adds lists a few other clubs that will attend: the Mets, Red Sox, Rangers and Astros.

Castillo is said by many to have plus-plus speed, and several scouting reports have comped him to Brett Gardner with a bit more power. The right-handed hitting 27-year-old has drawn praise for his line-drive stroke, and he’s thought of as a potential starting-caliber outfielder for a Major League club. Sanchez has tweeted a new scouting video of Castillo (including footage of him pushing a car — seriously), while a scouting report can also be seen over at Baseball America, courtesy of international guru Ben Badler. Castillo is represented by Roc Nation Sports.
