Diamondbacks-Phillies Game 1 Betting Preview

The Diamondbacks took the baseball world by storm by stunning the heavily-favored Dodgers in the NLDS. The D-backs claimed the first two games of the series at Dodger Stadium and sealed the deal with a 4-2 victory in Game 3. It marks Arizona's return to the NLCS for the first time since 2007.

Philadelphia secured its place in the NLCS by defeating the top-seeded Braves in four games during the NLDS. After splitting the first two games in Atlanta, the Phillies secured the series win with a 3-1 victory at home.

The Phillies, with 90 regular-season wins, played just over their over/under line set at 88.5. They entered the season with +900 odds to win the pennant. In contrast, the Diamondbacks exceeded expectations by winning 84 games, surpassing their over/under line of 75.5, and entering the season with +7000 odds to win the National League pennant.

NLCS Game 1 Pitching Match-Up

In his two postseason starts, Zach Wheeler has displayed a 2.25 ERA. He allowed just one run and five hits in 6 2/3 innings during the wild-card round against Miami. In the NLDS against Atlanta, Wheeler gave up two runs and three hits in 6 1/3 innings, along with one walk and 10 strikeouts. However, the Phillies lost that game 5-4.

The Phillies hold a 20-14 record with Wheeler on the mound this season, although a 22-12 record could more accurately represent his performance when examining individual games.

Zac Gallen, on the other hand, is also making his third postseason start. In the wild-card clincher against Milwaukee, he surrendered two runs and five hits across six innings during a 5-2 Diamondbacks win. Against the Los Angeles Dodgers in the NLDS, Gallen once again allowed two runs and five hits across 5 1/3 innings, this time during a 4-2 Diamondbacks victory.

Arizona holds a 21-15 record with Gallen on the mound this season, with a 22-14 record potentially providing a more accurate reflection of his performance when examining individual games.

Gallen's only start against the Phillies this season ended with him giving up two runs and five hits in 5 2/3 innings, although the Diamondbacks bullpen eventually allowed the game to slip away in a 6-5 loss.
