It’s been a second half of the MLB regular season to forget for Diamondbacks’ fans, especially those on Arizona sports betting sites, with the franchise falling into a heated race to make the playoffs.
Thanks to a 14-22 stretch after the break, the Torrey Lovullo-managed club has seen its postseason prospects plummet — with the D’backs looking as likely as not to miss out on the postseason for a sixth straight season. As a result of that slide, oddsmakers at Caesars Sportsbook Arizona have downgraded the D’backs’ playoff odds to +110 (with -130 odds the franchise will miss the postseason entirely), after the team won the first of a four-game home series against Cincinnati on Thursday.
To get a sense of where Arizona’s second-half slump ranks in recent MLB history, BetArizona.com stacked up the biggest win percentage differentials between halves of the season between 2018 and 2023.

Where D’backs Rank In Recent MLB History
The D’backs’ 2023 slump isn’t even the biggest this year, with the Marlins and Yankees both ranking ahead of Arizona. It is the biggest first-to-second half differential for the team between 2018 and 2023, however, ranking ahead of the 2018 squad that went from 53-44 at the break to 82-80 (-.110) at year’s end.
Luckily for Lovullo and company, the D’backs currently rank at the back end of the league’s top 10 toughest strength of schedules down the stretch, with a combined opponents’ win percentage of .508 (ranking in a tie with the Philadelphia Phillies for 10th overall), according to Tankathon.com.
With 34 regular season games remaining and four teams within a game of the final two playoff spots, there’s no time to waste for the D’backs if they want to turn the tide on their season.
You can use Arizona sportsbook promo codes to bet the Diamondbacks as favorites Friday night.
