The A's are making the move that the baseball world has been clamoring for, as No. 5 prospect Henry Bolte will be making his debut vs. the St. Louis Cardinals this week. This has been reported by numerous sources, and confirmed by MLB.com's Martín Gallegos. The move comes after the 22-year-old has been practically banging down the door of promotion. Bolte has been on a tear in Triple-A since the start of May, hitting .595 with a 1.741 OPS and smashing five home runs. He had a run where he went 12-for-12 at the plate over the weekend, and social media was in awe . Bolte obviously won the Pacific Coast League Player of the Week award after the run he has been on at the plate.
