Probably nothing. The Mariners have plenty of room on their 40 man roster. Even with the signing of Alaniz, the Mariners 40 man still only has 33 spots filled. So signing a career minor leaguer to a Major League deal like Alaniz, and Dylan Moore who you can learn about by clicking here, aren’t really that big of a deal.
The players are signed for the minimum and can easily be waived, DFA’d, or optioned without any major concern to payroll or the roster in general. But what is it about Ruben Alaniz that makes the Mariners so intrigued?
