Whakaotihia te rerenga e whai ake nei: I muri i nga pakanga a nga Cubs tata atu ki a José Veras i te timatanga o te tau 2014, i whakaingoatia a Rondón hei tata hou o Cubs. 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 wikitoria ngā Cubs i te
2016 World Series i runga i te Cleveland Indians, ka mutu te maroke o te 108-tau o te Cubs. Kaore ia i whakawhiwhia, a ka waiho hei kaihoko koreutu i te Tihema 1, 2017.
