The Pittsburgh Pirates have purchased right-handed pitcher Patrick Johnson from the Sioux City Explorers of the American Association. Johnson was recently rated as the fifth best prospect in independent ball by Baseball America. He was originally a 25th round draft pick of the Colorado Rockies in 2011. He was voted the American Association's Pitcher of the Year in 2015.
Johnson is 5'10" and 27 years old. According to the BA report, he mixes a 90-94 mph fastball with a solid average breaking ball and a change-up.
He topped out at High-A in the Rockies system and has spent the last two seasons in independent ball.
