Vesia was optioned to Triple-A Oklahoma City on Thursday, Fabian Ardaya of The Athletic reports.
Vesia has thrown 10.2 innings of relief for the Dodgers this season but hasn't had much success. His 33.3 percent strikeout rate is strong but hasn't been nearly enough to offset his 22.9 percent walk rate and a shockingly low 10.0 percent groundball rate. The left-hander's 5.91 ERA could be much higher if not for a .059 BABIP.
