Gale, who is just days from his thirtieth birthday, has seen limited MLB time in parts of two seasons. He spent the bulk of 2017 playing at Triple-A, where he slashed .278/.328/.365 over 377 plate appearances.
Despite his lack of opportunities in the majors, Gale certainly has ample experience in the upper minors. He first reached Triple-A way back in 2011 and has seen at least some action at the highest level of the minors in every ensuing season.
San Diego could still included Gale in its camp competition for the reserve catching role if he ultimately clears waivers. For now, though, veteran A.J. Ellis is likely in the lead for the job as the backup to starter Austin Hedges. The only catcher currently on the 40-man is Luis Torrens, who was kept on the active roster last year as a Rule 5 pick. Minor-league signee Rafael Lopez is also in camp along with non-roster invitees Stephen McGee and Austin Allen (neither of whom has yet appeared in the majors).
