PHOENIX (Interstat) — The San Francisco Giants and Arizona Diamondbacks, two teams locked in a tight battle for a potential wild-card spot, will continue their pivotal three-game series at Chase Field on Tuesday night.

Both clubs enter the contest with nearly identical records. The Giants (75-75) are looking to get back to .500 after a decisive 8-1 loss to the Diamondbacks on Monday. Arizona (76-75) used that victory to climb one game above the break-even mark and take a one-game lead over their National League West rivals in the overall standings.

The season series has been a back-and-forth affair, with the teams splitting the last 10 meetings. The Diamondbacks have won the last two contests, including a 5-3 victory in San Francisco on Sept. 10. The Giants, however, have shown an ability to score in bunches, winning games 11-5 and 7-2 earlier this month.

San Francisco has struggled recently, losing four of its last five games. Its offense was stifled Monday night, managing only one run on a solo home run by second baseman Casey Schmitt. Reliever Kai-Wei Teng provided a bright spot with four scoreless innings of relief.

Arizona, meanwhile, is riding a wave of momentum, having won four of its last five. Monday’s win was a complete team effort, highlighted by a strong six-inning start from Zac Gallen, who allowed just one run and struck out six. Shortstop Geraldo Perdomo went 3 for 3 with two RBIs.

According to Interstat, the Diamondbacks are projected as favorites with a 55.9% probability to win. Their game simulator predicts a 6-5 Arizona victory. Betting markets also favor the home team, installing Arizona as a -1.5 favorite with an over/under of 9 runs.

The outcome of this series could have significant implications for the postseason picture as the regular season enters its final weeks. Following Wednesday’s series finale, both teams face difficult stretches. The Giants travel to face the Los Angeles Dodgers for four games, while the Diamondbacks will host the Philadelphia Phillies before a season-ending series against the Dodgers and San Diego Padres.

First pitch is scheduled for 6:40 p.m. PDT.
