Washington Nationals host Philadelphia Phillies at Nationals Park on Thursday, 17 September at 8:45 am AEST. The Nationals sit fourth in the NL with a 71–81 record; the Phillies occupy second at 83–68 and trail the division leader by 5.5 games.

Washington are riding a four-game home winning streak — all four victories coming inside the last six days. Philadelphia arrive off a loss in this same building two nights ago, when the Nationals posted a 6–3 win. Jared Simpson gets the start for Washington; Zack Wheeler goes for the visitors.

Who will win?

The Nationals have won their last four starts at home — 4–3 over the Angels on 12 September, 6–5 the following day, 6–5 again on 14 September, then 6–3 over Philadelphia on 16 September. That home form lands them at an average of 5.5 runs for and 4 against across those four outings.

The Phillies are coming off that 3–6 loss at Nationals Park — their fourth defeat in five starts. Across those five matches Philadelphia have managed just 4 runs per game while conceding 6. Their lone win in that stretch came on 14 September, a 9–4 result against Atlanta.

Last time these two met was Wednesday night — Washington won 6–3 at home. The head-to-head ledger shows five meetings in recent months: the Nationals took two of five, including a 10–4 victory in August. The combined scoring average across those five contests sits at 9.4 runs.

The head-to-head market has Philadelphia at 1.52 and Washington at 2.55. The Phillies carry the better season record and run differential, but Washington's current home surge — four straight wins at Nationals Park — rates a real chance of extending.

Same Game Multi options

A few priced combos are on the board: Nationals to win, Over 3.5 Nationals total runs in the match and James Wood to hit 1+ home runs pays 8.00. Step that Nationals total up to 5.5 runs and pair it with a CJ Abrams home run for 11.00.

On the other side, Phillies to win, Over 7.5 Phillies total runs in the match and Bryce Harper to hit 1+ home runs is also at 11.00. The Nationals combos align with their recent home scoring output; the Phillies option requires a much bigger offensive showing than they've managed lately.
