Before the San Antonio Spurs and Oklahoma City Thunder tip off, eligible bettors can secure this welcome bonus with DraftKings Sportsbook. Getting started is incredibly straightforward, as there is no manual code required to claim your guaranteed value.
To take advantage of this lucrative welcome offer, new DraftKings customers simply need to create an account and place a qualifying wager of at least $5 on the upcoming NBA matchup between the Spurs and the Thunder. One of the best features of this promotion is that the payout is fully guaranteed鈥攎eaning new users will receive the bonus whether their initial bet wins or loses. It does stand to reason that locking in a guaranteed payout is the smartest play you can make, but just make sure your qualifying wager is placed on a market with odds of -500 or longer to remain eligible.

This is paid out as four separate $25 bonus bets, giving you the flexibility to spread your wagers across the rest of the NBA slate or hunt for a longshot in other betting markets.

When looking under the hood, the Thunder hold a slight edge in estimated Net Rate at 17.6 points per 100 possessions, while the Spurs are right behind them with a stellar 16.6 Net Rate.

Bettors breaking down this matchup should note a few highly relevant recent trends. The San Antonio Spurs have thrived against quality competition, going 4-1 (.800) against the spread (ATS) over their last five games when facing opponents with a winning record. Meanwhile, the Oklahoma City Thunder have been pushing totals high; the Over has hit in six of the Thunder’s last seven matchups against teams with a winning record, which aligns interestingly with the current 221.5-point total set by oddsmakers.
Official Prediction: We’ve seen time and time again that dominating the glass travels well in the postseason. Given the Spurs’ rebounding edge and their profitable 4-1 ATS mark against quality teams, there is clear value on the underdog here. Take the San Antonio Spurs +6.5 (-110) at DraftKings. Additionally, the Thunder’s trend of playing in high-scoring games against winning teams makes Over 221.5 (-105) a sharp, data-backed angle.
