Diamondbacks Rally Behind Unlikely Hero in Critical Series vs. Cardinals

The Arizona Diamondbacks are facing a major challenge off the field, but it didn’t stop them from getting a huge win on it. Playing without their All-Star second baseman, the Arizona Diamondbacks will look for their second straight victory in a critical wild-card series against the visiting St. Louis Cardinals on Saturday.

Playing for Marte

The Diamondbacks were dealt a major blow before the series opener when they had to place All-Star Ketel Marte on the restricted list. Marte’s home was burglarized while he was away at the All-Star Game, and he has been given time off to deal with the personal matter.

“I would love it if he was here, but he’s not, and we just have to deal with the circumstances,” a supportive manager Torey Lovullo said. “I’m very respectful of the position he’s in right now.”

The “Next Man Up”

In Marte’s absence, an unlikely hero stepped up. Adrian Del Castillo, just recalled from Triple-A, had three hits, scored two runs, and drove in another to lead the D-backs to a 7-3 victory on Friday. It was the kind of “inspired” performance that Lovullo wants to see become the new standard for his team. How a team rallies in the face of adversity is a key topic in our expert betting guide.

A Duel of Aces on the Mound

Saturday’s game features a premier pitching matchup between two of the hottest right-handers in the National League. The Cardinals will send their ace, Sonny Gray (9-3, 3.50 ERA), to the mound. Gray has been fantastic over his last 10 starts, posting a 2.64 ERA.

The Diamondbacks will counter with their own hot hand in Ryne Nelson (5-2, 3.68 ERA). Nelson is 3-0 with a 2.43 ERA in his last six starts. This elite duel will be the main event on the scores and odds board.

The Wild Card Race

This series has a playoff atmosphere, as the Cardinals currently hold the final NL wild-card spot, with the Diamondbacks just 2 1/2 games behind them. For two MLB teams looking to make a second-half push, every game is crucial. To see which ace our experts think will lead his team to victory, check out our daily MLB picks.
