From BA's Clint Longenecker on Mr.Jackson at the Arizona Senior Fall Classic: Alex Jackson (Rancho Bernardo HS, Escondido, Calif.), one of the top position players in the country, was an offensive force Friday. Jackson went 2 for 4 but hit everything hard with good exit velocity up the middle. Jackson hit a shot deep to dead center field close to the base of the wall 410 feet from home plate that the defender made an error on in his first plate appearance. In his third trip to the plate, Jackson roped a triple that one-hopped the center field fence. He sent a screaming liner back up the box that nearly killed the pitcher in his next plate appearance. Jackson walked and struck out looking in his other two plate appearances. “I have been working on compacting my swing because this summer. I didn’t have time to sit there and load against big velocity, I have been working on firing quickly,” Jackson said. “It’s definitely something I have worked on and it has been feeling great.” Jackson, who has seen most of his time behind the plate and some time in the right field, played third base for the Yankees Scout Team Friday. “I grew up playing short and have probably played about five games at third since freshman year but I take ground balls every once in a while to keep my hands going,” Jackson said.
