Diamondbacks vs. Padres Prediction, Winner Payout, Over/Under – Wednesday, July 8

For this game, the Diamondbacks will start rookie SP Jose Cabrera (5.13 xFIP in 13.1 IP, 3 starts). The 24-year-old from the Dominican Republic has gotten his first taste of the big leagues. His debut went well, seeing him go 5 scoreless innings against the Twins.

However, his next two starts against the Rays and Brewers have not been as successful, as he's given up 7 earned runs over 8.1 frames. Arizona believes Cabrera is an “under the radar” prospect, noting that he's improved his fastball velocity and breaking pitches as he develops.

The Diamondbacks will have to make some big decisions over the next few weeks. With the trade deadline approaching, do they try to improve the team or start a rebuild? They're 14 games back in the NL West but are only 4.5 games out of a WC spot, so there could be something to play for.

The Padres will counter with SP Michael King (4.40 xFIP in 102.1 IP, 18 starts). King was part of that Juan Soto trade, and he’s been a great return. Although King has been one of their more consistent pitchers during his tenure, he’s recently had some rough outings.

In his first 56 starts with San Diego, he'd never gone three straight starts allowing 3+ earned runs. He recently went five straight doing so, but he may have gotten back on track by firing 7 scoreless innings against the Braves and going 6 innings with 2 earned vs. L.A.

It's getting ugly in San Diego. It was only five weeks ago that the Padres were in first place in the division. Since having a half-game lead in the NL West on May 18, they're an MLB-worst 15-28. Unless things drastically change before the end of July, there may be grounds for a fire sale.
