Buuxi weedha soo socota: Horraantii xilli ciyaareedkii 2018, kulankii April 11 ee ka dhanka ahaa New York Yankees ee Fenway Park, Kelly wuxuu ku dhuftay Tyler Austin, ka dib markii Austin uu ku eedeeyay in uu ku dhuftay ciyaaryahanka Brock Holt. Austin wuxuu ku eedeeyay Kelly wuxuuna bilaabay isku dhaca kursiga keydka; afar ciyaartoy, oo uu ku jiro Kelly, ayaa la tuuray. Tani waxay ahayd Kelly shaqadeeda markii ugu horeysay ee la iska tuuro. Bishii Abriil 12, Kelly waxaa laga joojiyay MLB muddo lix ciyaarood ah waxaana lagu ganaaxay lacag aan la shaacin; wuxuu markii dambe racfaan ka qaatay, isaga oo u oggolaanaya inuu sii wado ciyaarista illaa geeddi-socodka racfaanka la dhammeeyo. Bishii Abriil 26-keedii, rafcaanka Kelly waa la diiday, taasoo la micno ah in xayiraaddiisu ay dhaqan geli doonto laga bilaabo xilligaas. Intii lagu jiray ganaaxiisa, Kelly wuxuu ciyaar ka daawanayay kuraasta fadhiga ee Fenway Park. Wuxuu u soo muuqday xirfad sare 73 kulan Red Sox, isagoo ku dhameeyay 4.39 ERA wareegyada. Xilli ciyaareedkii dambe, Kelly wuxuu sameeyay sagaal muuqaal, isagoo dhaliyay wareegyo isagoo u oggolaanaya hal orod oo uu kasbaday oo uu garaacay 13. Wuxuu ahaa ciyaaryahankii ku guuleystay ciyaartii 4aad ee horyaalka
World Series, sida Red Sox ay uga adkaadeen Los Angeles Dodgers shan kulan.
