CLEVELAND (AP) — Andre Drummond returned from a leg injury to score 28 points and add 17 rebounds, and Kevin Love made a big 3-pointer in overtime to lift the Cleveland Cavaliers to a 132-129 win over the San Antonio Spurs on Sunday night.Drummond, who missed the past three games with a strained left calf, put the Cavs up 124-22 with a layup and Love followed with his 3 from the corner 28 seconds later to put Cleveland up by five.Love had missed his first four attempts from long range before his clutch shot and he finished just 3 of 12 from the field, but added 18 rebounds.Derrick White hit a 3 to pull the Spurs within 131-129 in the final seconds, but Collin Sexton made a free throw for the Cavs and San Antonio didn't get off a last-second heave in time.It was the second straight close win for the young Cavs, who beat Denver 104-102 on Saturday. Cleveland improved to 5-5 under coach J.B. Bickerstaff.Sexton scored 26, Larry Nance Jr. 19 and Matthew Dellavedova had 14 and 11 assists.

But after a timeout by San Antonio, Gay dropped a 20-foot jumper to tie it with one second left. Gay twice tied the game in the final 1:02 with 3-pointers.The first half turned into a prolonged free-throw shooting contest as the officials called 33 fouls, leading to a combined 46 free throws by both teams. San Antonio made its first 15 and went 21 of 23 from the line, while Cleveland finished 20 of 23.With Drummond back in the lineup and Aldridge out for San Antonio, the Cavs attacked the rim and led by double digits for much of the first half. But the Spurs, who made just 1 of 11 3-point attempts in the first half, warmed up from the outside and scored 41 in the third to carry a 91-87 lead into the fourth.TRAIL BLAZING WOMENOn International Women's Day, both teams could celebrate their female assistant coaches: Becky Hammon with the Spurs, Lindsay Gottlieb with the Cavs.Hammon became the first female coach in NBA history in 2014.
