EDGE Analysis

Jansen, a 22-year-old backstop, is arguably the organization's breakthrough player of the year. He hit .369 with a .963 OPS through 31 games with Dunedin, then slashed .291/.378/.419 over 52 contests at Double-A New Hampshire. Jansen has unexpectedly emerged as the Jays' top catching prospect with an outstanding campaign, and his efforts will likely land him an invite to next year's spring training.
