Newly selected Basketball Hall of Famer Ben Wallace tapped his fist on the table a few times, then clapped his hands and pointed one finger skyward.

After one of the worst seasons in franchise history, Detroit has something to celebrate.

The Pistons won the NBA draft lottery on Tuesday night, meaning they’ll have the No. 1 pick on July 29 — and, presumably, the chance to take Oklahoma State guard Cade Cunningham.

Houston — which basically had 50-50 odds of picking in the top four — got the No. 2 pick. Cleveland will pick No. 3 and Toronto will pick No. 4, after both of those franchises got some lottery luck to move up in the order.

Orlando will get the No. 5 and No. 8 selections, with Oklahoma City picking No. 6 and Golden State also with two lottery slots — No. 7, as part of a trade with Minnesota, and the Warriors’ own pick at No. 14.

The rest of the lottery results: Sacramento picks No. 9, New Orleans No. 10, Charlotte No. 11, San Antonio at No. 12, and Indiana at No. 13.

And form held through the first six picks that were unveiled. The No. 8 pick, which was slotted to Chicago, winds up with the Magic as part of the Nikola Vucevic trade from this season. That’s when the first significant buck-the-odds move happened, when Toronto’s 31.9% chance of cashing into a top-four slot delivered.

The Thunder will have three first-round picks, but none higher than No. 6. 

The consensus opinion has been that the No. 1 pick will be either a one-and-done college player — Cunningham, Southern California center Evan Mosley or Gonzaga guard Jalen Suggs — or someone from the G-League development program like guard Jalen Green or forward Jonathan Kuminga.

The rest of the first round, for now, is slotted this way — Washington will pick 15th, followed by Oklahoma City, Memphis, Oklahoma City, New York, Atlanta, New York, the Los Angeles Lakers, then Houston at both No. 23 and No. 24, followed by the Los Angeles Clippers, Denver, Brooklyn, Philadelphia, Phoenix and Utah.
