San Antonio at Miami

Streaky Miami has lost four straight after winning seven in a row, and it took a tip-in by Amen Thompson at the buzzer for Houston to beat the Heat 123-122 on Saturday despite Miami missing three of its top five scorers for most of the game. San Antonio is also dealing with some key injuries as Stephon Castle has missed the past two games with a hip injury, and Devin Vassell (hamstring) did not play against Indiana. Miami is 21-15 ATS at home this season, including a current 7-2 ATS run, and the Heat are 5-0 ATS in their past five games against Southwest Division opponents. Miami has covered four of the past six meetings, and it has won six of the past seven meetings at home. The Spurs are just 4-5 ATS in their past nine games overall. Take the Heat.
