Lionel Messi played off the bench for Inter Miami on Saturday at Toronto, the next-to-last contest of the regular season for the MLS Supporters Shield winners. Messi, the eight-time Ballon d'Or winner, came on as a reserve in the 61st minute, as did fellow would-be starter Sergio Busquets. Also out of the starting 11 for Inter Miami on Saturday were Jordi Alba, Luis Suarez and goalkeeper Drake Callender. Inter Miami coach Gerardo Tata Martino indicated Friday that Messi's workload would be a consideration now that the team has wrapped up the No. 1 seed and home-field advantage for the entirety of the MLS Cup playoffs. Inter Miami will play its first playoff match at home on Oct. 25. Messi is set to report to Argentina's national team in the coming days for World Cup qualifying matches on Oct. 10 and Oct. 15. Those matches, and the travel involved, would figure to put his availability in some doubt for Inter Miami's regular-season finale at home on Oct. 19 against New England. Osca
