Non-World Baseball Classic pitchers and catchers reported to Peoria on Wednesday, Feb. 11, marking the beginning of Spring Training as the baseball offseason concludes. While much of the news for the Mariners revolved around the additions to the major league team, there are quite a few prospects looking ahead to Spring Training as a showcase of their skills.

This is the third part of a series of four articles detailing some of the non-roster invites (NRIs) that will make appearances in the Mariners’ Spring Training this year; the first two parts can be found here and here. Unlike part two, which went over some of the higher-end pitchers in the Mariners’ system - who are expected to be starters - this piece goes over hurlers further down in the organization’s depth, mostly expected to slot into a relief role.

1. RHP Teddy McGraw, 24 years old, High-A.

McGraw has the stuff to reach the majors in some capacity, but a laundry list of injuries over his time in the minors have made it uncertain whether he is still on track to become a big league starter. In any case, his pitch profile - a running sinker combined with a sweeper and a four-seamer - suggest he might fit best as a reliever.
