FINAL: LAKERS 106, Suns 103

The Los Angeles Lakers advanced to the semifinals of the In-Season Tournament with a controversial win over the Phoenix Suns. Late in the fourth quarter, the Lakers were clinging to a two-point lead when they were granted a timeout and the ball despite no one having control. Anthony Davis only hit one of his two free throws on the ensuing possession, but that was enough to ensure a Lakers' win.

LeBron James finished with 31 points, 11 rebounds, eight assists and five steals to lead the way for the Lakers. In the process, he became the first Lakers player with at least 30 points, 10 rebounds, five assists and five steals in a game since Magic Johnson in 1987. 

Our Sam Quinn broke down the controversial timeout call.

FINAL: BUCKS 146, Knicks 122

After two upsets in the In-Season Tournament's quarterfinals on Monday, Tuesday sent our first favorite to Las Vegas. The Milwaukee Bucks overwhelmed the New York Knicks, 146-122, behind an absolutely incredible 3-point shooting performance. The Bucks, now 5-0 in tournament play, made 23 of their 38 3-point attempts (60.5% in total from deep), and a Knicks team that relies on defense over shooting just couldn't keep up. Julius Randle led all scorers with 41 points, but Milwaukee got 63 from stars Giannis Antetokounmpo and Damian Lillard combined in the victory.

Now the Bucks will travel to Las Vegas to face off with the Indiana Pacers in the semifinals of the In-Season Tournament.

Our Jack Maloney has all the details on the Bucks' offensive outburst.

FINAL: Pacers 122, Celtics 112

The Pacers were the first team to punch their ticket to the In-Season Tournament semifinals. Tyrese Haliburton had a game to remember with a triple-double: 26 points, 10 rebounds and 13 assists. The Pacers won at home and outscored the Celtics by 17 points in the second half. Jayson Tatum and Jaylen Brown combined for 62 points for Boston, but it wasn't enough.

CBS Sports' Sam Quinn wrote about why Haliburton is exactly the kind of star that should shine in the In-Season Tournament.
