Indiana has won five of the last six playoff games between the teams and never trailed in this one. The Pacers had lost three of four regular-season games to the Bucks. The teams will meet for the 18th time in the last two seasons on Friday, when Game 3 is played in Milwaukee.

Two-time league MVP Giannis Antetokounmpo had 34 points, 18 rebounds and seven assists, and All-NBA guard Damain Lillard had 14 points in his first game back from deep vein thrombosis in his right calf. Lillard was 4 of 13 from the field in 37 minutes, his first game action since March 18 and his first playoff game with Antetokounmpo, who heard a steady diet of countdowns on his free throws.

Bobby Portis Jr. finished with 28 points, including six 3-pointers, and 12 rebounds for the Bucks.

Thunder 118, Grizzlies 99: Shai Gilgeous-Alexander scored 27 points, and Oklahoma dominated Memphis to take a 2-0 lead in their first-round playoff series.

Jalen Williams added 24 points and Chet Holmgren had 20 points, 11 rebounds and five blocks for the Thunder.

Oklahoma City delivered a strong follow-up to its record-setting 131-80 win on Sunday in the series opener. The Thunder have won all six games against the Grizzlies this season by double digits.

Jaren Jackson Jr. scored 26 points and Ja Morant added 23 for Memphis, which will host Game 3 on Thursday.

Celtics’ Tatum doubtful for Game 2: Boston forward Jayson Tatum has been listed as doubtful with a bone bruise in his right wrist for Game 2 of Boston’s Eastern Conference first-round series against the Orlando Magic today. Tatum’s designation was listed on the injury report released Tuesday. He injured the wrist in the fourth quarter of the Celtics’ 103-86 victory on Sunday.

With Boston leading 89-73 with 8:28 remaining, Tatum went up for a dunk and was hit hard by Kentavious Caldwell-Pope as he tried to block it. Tatum landed awkwardly on his right side.

He stayed down briefly before eventually rising to his feet, clenching his right hand. Tatum subsequently missed the two ensuing free throws but remained in the game. Tatum said a postgame X-ray came back clean.

Boston’s Pritchard named sixth man of the year: Payton Pritchard, who was the only player in the NBA with more than 1,000 points in games that he didn’t start and set the league record for 3-pointers made by a backup, was named the league’s sixth man of the year.

Pritchard topped Detroit’s Malik Beasley and Cleveland’s Ty Jerome for the award.

Pritchard led all reserves in points (1,079 in the games in which he did not start), 3-pointers (246, not including nine more he made in his three games as a starter), along with plus-minus (+428). And among nonstarters, his assist total of 257 ranked third-best in the league behind only Indiana’s T.J. McConnell and Portland’s Scoot Henderson.

Timberwolves’ Edwards fined: Minnesota’s Anthony Edwards has been fined $50,000 for directing inappropriate language and making an obscene gesture toward a fan during a playoff game against the Los Angeles Lakers, NBA president of league operations Byron Spruell announced.
