4:15 p.m. ET: St. Louis Cardinals (-125, 8.5) at Arizona Diamondbacks

The Diamondbacks (48-50) cruised to a 7-3 win in yesterday’s series opener, cashing as a -110 home pick’em.

In this late afternoon rematch, the Cardinals (51-47) send out righty Sonny Gray (9-3, 3.50 ERA) and the Diamondbacks go with fellow righty Ryne Nelson (5-2, 3.68 ERA).

This line opened at roughly a pick’em, with both sides listed around -110 odds.

Sharps have pounced on the Cardinals to get back on track, steaming St. Louis up from a -110 road pick’em to a -125 road favorite.

At DraftKings, the Cardinals are taking in 57% of moneyline bets and a 65% of moneyline dollars, indicating slight public support but also respected smart money. At Circa, St. Louis is receiving 88% of moneyline bets and a hefty 92% of moneyline dollars, signaling heavy one-way support from the wiseguys in the desert.

St. Louis has betting system value as a non-division favorite, with the lack of familiarity benefiting the “better” team who is expected to win the game.

The Cardinals are 15-4 in Gray’s 19 starts this season.

St. Louis has the better bullpen, sporting a team ERA of 3.80 compared to 5.00 for the Diamondbacks (4th worst in MLB).

6:40 p.m. ET: Houston Astros at Seattle Mariners (-130, 8)

The Mariners (52-45) dominated last night’s series opener 6-1, taking care of business as -150 home favorites.

In tonight’s rematch, the Astros (56-41) send out righty Lance McCullers Jr. (2-4, 6.48 ERA) and the Mariners tap fellow righty Logan Evans (3-3, 3.75 ERA).

This line opened with Seattle listed as a -120 home favorite and Houston a +100 road dog.

Sharps are riding the hot hand and have laid the short chalk with the Mariners, steaming Seattle up from -120 to -130. Some shops are even creeping up to -135.

At DraftKings, the Mariners are receiving 62% of moneyline bets and 65% of moneyline dollars. At Circa, Seattle is taking in 71% of moneyline bets and 95% of moneyline dollars. Both books are showing a sharp “low bets, higher dollars” bet discrepancy in favor of the home chalk.

The Mariners have correlative betting value as a favorite in a low total game (8), with the fewer amount of expected runs scored more likely to come from the “better” team who is expected to win.

Evans is 2-0 with a 2.28 ERA at home this season.

Meanwhile, McCullers Jr. is 2-4 with a 7.59 ERA in night games.

Seattle is 3-1 against Houston this season.

The Mariners have played better than the Astros as of late, going 7-3 in their last ten games and hitting .260 with a 3.57 team ERA compared to Houston going 4-6 and hitting .250 with a 4.50 team ERA.
