The Arizona Diamondbacks (30-35) and San Diego Padres (34-34) wrap up a 4-Game series at Petco Park Sunday. First pitch is scheduled for 4:10 p.m. ET (ESPN+). Let’s analyze FanDuel Sportsbook’s lines around the Diamondbacks vs. Padres odds and make our expert MLB picks and predictions for the best bets.

Season series: Padres lead 4-2

The Diamondbacks won the series opener Thursday by a 4-3 score, but the Padres have been rude hosts the past 2 days. San Diego won 10-3 on Friday, and 13-1 on Saturday, easily cashing as the favorite while hitting the Over both days.

Despite the 2 blowout losses, Arizona is still a respectable 5-3 in the past 8 games, while cashing the Over at 7-2 clip in the previous 9 contests.

The 23 runs scored the past 2 days is the most scored in consecutive Games by the Padres this season. The 2 routs come after a 5-Game losing skid which saw the team average just 2.2 runs per Game (RPG), cashing the Under in each outing.

Diamondbacks at Padres picks and predictions

Prediction

Padres 8, Diamondbacks 3

Moneyline

The PADRES (-130) are a good play behind the rookie Mazur, who makes his home debut at Petco Park. He had a solid outing against the Angels in his 1st taste of the majors last time out.

The Diamondbacks (+110) counter with McGough, who has been a disaster in relief. He’ll serve as the opener, turning it over to an Arizona bullpen which has also been erratic, allowing 27 HR with a 4.48 ERA, which ranks 6th-worst in the majors.

Run line/Against the spread

It’s tough to trust a rookie making just his 2nd-ever start in the majors, but the PADRES -1.5 (+162) are worth a roll of the dice for the more adventurous bettor.

San Diego will get a shot at the shaky Diamondbacks +1.5 (-196) bullpen early in the game, and we could have another rout in the series finale.

Over/Under

OVER 8.5 (-115) is the play, based mostly on the poor pitching of McGough, and the fact the Padres have piled up 24 runs the past 2 games, and they’ll get to face the Diamondbacks for an extended period.

The Over is 4-1 in the past 5 Games for the Diamondbacks, and 7-2 in the previous 9 outings. The Padres have hit the Over in 3 of the past 4 Games at home.
