Yacabonis was added to San Diego's 60-man roster pool Sunday.
The right-hander joined the Friars on a minor-league deal in December and will join the team for the closing stages of summer training. Yacabonis made 29 appearances (four starts) for the Orioles last season and posted a 6.80 ERA, 1.83 WHIP and 33:24 K:BB across 41 innings before being designated for assignment in August.
