Tuesday's second win-and-in game features a reeling No. 7 Celtics team taking on a surging No. 8 Wizards squad. Boston posted a losing record after the All-Star break and was dealt a huge blow when Jaylen Brown (wrist) was declared out for the season. That forces Jayson Tatum to carry even more of a load than he's done all season, but he hasn't disappointed as one of the top NBA DFS picks. But he and Boston have a huge task ahead of them at 9 p.m. ET vs. a Washington team that has won 17 of its last 23 games.

Tatum ($9,800 on DraftKings, $10,000 on FanDuel) is one of the top options in Tuesday's shallow NBA DFS player pool. With just four teams in action tonight, you'll need to know these rosters front and back to select the best players for your NBA DFS lineups. Before locking in any NBA daily Fantasy basketball lineups for Tuesday's NBA DFS action, be sure to see the core lineup selections, player pool and NBA DFS strategy from SportsLine's Mike McClure.

Now, McClure has turned his attention to the Tuesday, May 18 NBA DFS slate and locked in his top daily Fantasy basketball picks. You can only see them by heading to SportsLine.

One of McClure's top NBA DFS picks for Tuesday is Pacers forward Domantas Sabonis at $10,000 on DraftKings and $10,300 on FanDuel. The two-time All-Star is listed as questionable with a bruised quad, but he is expected to play after posting 25 points, 16 rebounds and five assists vs. the Raptors on Sunday.

For the season, Sabonis is averaging 20.3 points, 12.0 rebounds and 6.7 assists per game. He's one of just four players averaging at least 20 points, 10 rebounds and six assists as he's become the Pacers' go-to guy on offense. In late January, Indiana played Charlotte in back-to-back games and Sabonis had mirrored performances with 22 points and 11 boards in each contest. With the season on the line for the Pacers, expect the team to put the ball in the hands of Sabonis quite often, making him a great NBA DFS asset on Tuesday.

Part of McClure's NBA DFS strategy for Tuesday includes rostering Wizards forward Rui Hachimura at $5,000 on DraftKings and $5,100 on FanDuel. The second-year player averaged 13.8 points, 5.5 rebounds and 1.4 assists this season. He's coming off a 16-point, six-rebound game on Sunday and has scored in double-figures in 10 straight outings.

Hachimura played his best when it mattered the most as he increased his scoring output when Washington made its play-in push. During May, he's averaging 17.0 points per game, a jump of nearly seven points over his April production. He scored 17 points and 15 points in two games vs. Boston earlier this season, and now he won't have to deal with Brown (wrist), who is out injured. Also, with the NBA's second-leading scorer, Bradley Beal (hamstring), playing hurt, the team may be more reliant on Hachimura than normally, so you can see why McClure is high on him.

McClure is also targeting a player who could go off for massive numbers on Tuesday because of a dream matchup. This pick could be the difference between winning your tournaments and cash games or going home with nothing. You can only see who it is here.
