Jansen struck out one in a clean ninth Wednesday against Arizona for save No. 43 of the season.
He just keeps on cruising along, having allowed only a single baserunner in four September appearances. Jansen and O's closer Zach Britton remain in a cross-country duel for the league's most impressive relief stats -- Britton owns an insane 0.65 ERA, but Jansen owns a matching (and even insaner) 0.65 WHIP.
