The Arizona Diamondbacks (11-13) take on the St. Louis Cardinals (10-13) Tuesday in the 2nd game of a 3-game set at Busch Stadium at 7:45 p.m. ET. Let's analyze BetMGM Sportsbook's lines around the Diamondbacks vs. Cardinalsodds and make our expert MLB picks and predictions for the best bets.

Season series: Tied 2-2

The Cards walked it off Monday night as 2B Nolan Gorman hit a 2-run shot to win it 5-3. We cashed 2 of 3 bets here as RHP Lance Lynn fell short of the 16.5-out threshold with 5 innings. He allowed 3 runs over 7 hits and 3 walks while fanning 7 in an uneconomical 5 innings. Arizona led 3-0 after 5 innings as 3B Eugenio Suarez went 3 for 4 with 2 RBIs. D-Backs RHP Brandon Pfaadt actually had a perfect game going until the 6th.

The Cards struck for 2 in the 6th, and 1B Paul Goldschmidt ended a 20-game drought with a homer in the 7th to tie it. Gorman entered the game as a defensive substitution in the 8th, and he took the first pitch he saw 425 feet into the right field stands to end an 0-for-19 slump in the 9th. The Cards' pen threw 4 shutout innings in the W.

Diamondbacks at Cardinals picks and predictions

Prediction

Diamondbacks 4, Cardinals 3

Moneyline

Henry has been the tale of 2 tapes thus far. In 2 home starts, he has yet to go 5 IP and allowed 5 ER. In 2 road starts, in Colorado and Atlanta mind you, he went 5 and allowed 2 ER in each. The Cards are 3-1 against left-handers this season, but Henry is the kind of lefty that predominately gives St. Louis trouble. Matz has given up 9 runs (6 earned) in his last 2 starts, and Arizona gets to him.

Take the DIAMONDBACKS +115.

Run line/Against the spread

I'm foregoing the spread here and zoning in on Henry. We mentioned his drastic home/road splits, albeit in a small sample size. He has a 9.9 K/9 in 2 road starts as opposed to 7.6 at home. He struck out 7 Cards over 5 1/3 IP in his only start against them.

Take TOMMY HENRY OVER 4.5 STRIKEOUTS (+110).

Upon logging into BetMGM, there was a 33% MLB Odds Boost, which makes this a beefy +146.

Over/Under

The Under 8.5 prevailed Monday. The Over is now 3-6-1 for Arizona in its last 10, and St. Louis is 3-7. It's slated to be 60 degrees with a light 6-mph gust swirling out to right-center.

We said this was dicey Monday, and it's dicey again Tuesday. But take the value and LEAN UNDER 8.5 (+100).
