Tuhia he haere tonu mō tēnei wāhanga - I muri i ngā pakanga a te kaitiaki Cubs a José Veras i te tīmatanga o te tau 2014, i whakaingoatia a Rondón hei kaitiaki Cubs hou. I whai wāhi ia i te tau 2014. I whiwhi ia i nga whakaora e rua i te 2015 National League Division Series ki te St. Louis Cardinals, tae atu ki te whakaora i te raupapa-whakaputa kēmu 4. I te taapiringa o Aroldis Chapman i te mutunga o Hurae 2016, i nekehia a Rondon ki te tūranga whakaturanga i roto i te bullpen. I mutu a Rondon i te tau 2016 me te rekoata 2-3 me te 3.53 ERA i roto i nga whakaaturanga 54. I riro i ngā Cubs te 2016 World Series
i runga i nga Inia o Cleveland, ka mutu te waipuke 108 tau o nga Cubs. Kaore ia i whakawhiwhia, a ka waiho hei kaihoko koreutu i te Tihema 1, 2017.
