Pistons (-3.5) vs. Cavaliers (-105)
Cade Cunningham proved why he's one of the NBA's best as the Pistons rallied from a 3-1 deficit to knock off the Magic in seven games in the opening round. The No. 1 pick in the 2021 NBA Draft scored more than 30 points in each of the Pistons' final three games, averaging 36.3 points per game, as the Pistons won the three contests by an average of 14.3 points to take the series. The Pistons had the best record in the Eastern Conference this season at 60-22, eight games better than Cleveland, and they are coming off a 116-94 win in Game 7 at home on Sunday. The Cavaliers are coming off a tough seven-game series against the Raptors in which the home team won each time, and the model is siding with host Detroit on Tuesday, projecting the Pistons to win by an average of seven points in its simulations.

Lakers (+15.5) vs. Thunder (-110)
The Lakers proved that even without Luka Doncic (hamstring), they have plenty of winning players on their roster, led by an all-time great in LeBron James. The Lakers defeated the Rockets in six games in the opening round, building off a 19-5 close to the regular season. Tuesday is certainly a significantly tougher test on the road against the defending champions, but the Thunder are 5-8 against the spread over their last 13 home games as they are often sizable favorites, like on Tuesday. James averaged 23.2 points, 7.2 rebounds and 8.3 assists per game last series against the Rockets, and Austin Reaves is back after missing the first four games of the previous series with an oblique injury. The model believes the Lakers have enough talent to keep this game within the margin as Los Angeles covers in 53% of simulations.

Pirates (+105) vs. Diamondbacks
"Every team in the NL Central has a winning record, and the leader of the division is the Cubs, who just swept the Diamondbacks over the weekend. The Diamondbacks have now lost four straight games and have fallen one game below .500," SportsLine expert Micah Roberts said. "We're at that junction already speculating if Arizona is a .500 team this year, while I have high hopes for the Pirates to make the postseason. Bubba Chandler starts for the Pirates on Tuesday, and he's been shelled in his last two games, allowing nine runs total with three home runs allowed. He'll be more effective on Tuesday. Arizona has won Eduardo Rodriguez's last four starts, but he allowed 10 runs in his last three. Pirates continue their winning."
