Ochinko was part of a trio of Minor League players suspended, joining Angels outfielder Brandon Bayardi and Mets pitcher Daniel Huchingson.
Ochinko has split time between Double-A New Hampshire and Buffalo this season, posting a combined .231 average with five home runs, 37 RBIs, a .294 OBP and a .607 OPS in 91 games.
Last season one of the Blue Jays' top prospects, Marcus Stroman, was suspended 50 games for using the banned substance Methylhexaneamine.
Stroman has since put the suspension behind him with an 8-4 record, a 3.22 ERA and 117 strikeouts over 100 2/3 innings in New Hampshire this season.
