As of January 9th, Brendan Donovan is still a St. Louis Cardinal. Despite heavy interest and rumors swirling, Donovan hasn't been traded by president of baseball operations Chaim Bloom. Player names have been discussed in various packages, but they haven't been enough for Bloom to budge from his asking price.
Teams have been waiting out Chaim Bloom thus far, hoping he would lower his price. With other free agent second basemen (Bo Bichette, for example) as options, teams were able to wait for Bloom to lessen his price tag. Ketel Marte, a superior hitter to Donovan with more team control, was also a target for several teams at second base via trade.
