It was hinted at on Saturday but is now official.
According to MLB.com’s Jesse Sanchez, the Padres announced Sunday that top pitching prospect Casey Kelly will make his major league debut on Monday night at Petco Park against the Braves.
Kelly was acquired by the Padres back in December of 2010 as part of a four-player return package from the Red Sox for first baseman Adrian Gonzalez.
The 22-year-old former first-round pick has posted a 3.35 ERA, a 0.96 WHIP and a 39/3 K/BB ratio across 37 2/3 innings this season in the Padres’ minor league system. He missed the early part of the summer with a right elbow strain but is now fully healed.
Kelly ranked 76th this past winter on Baseball America‘s Top 100 prospects list. He was 31st in 2011.
