San Diego Padres vs. St. Louis Cardinals Prediction & Player Props

The San Diego Padres and St. Louis Cardinals will begin a three-game series in St. Louis on Monday night, and both clubs could use some sustained success.

It has been a bit of a scuffle for the Padres over the past month, but they are coming off back-to-back wins over Baltimore. The Cardinals are 7-3 in their last 10 games, but they are also 1-3 in their last four after dropping a series against Minnesota over the weekend.

With Monday’s contest set for 7:45 pm ET, it’s time to break down the matchup and discuss the best bets to make.

San Diego Padres vs. St. Louis Cardinals betting picks and predictions

St. Louis Cardinals ML (-160)

A return to St. Louis following a six-game road trip should be just what the doctor ordered for the Cardinals following their series in Minnesota, as they are 4-0 in their last four home games.

Handing the ball to Dustin May should also help. Don’t be fooled by the right-hander's 4.21 ERA. He has been impressive ever since a rough first two appearances this season in which he gave up 13 earned runs in a combined 7.1 innings.

May has been especially dominant in recent weeks. He concluded the month of May with only one earned run allowed in 7.0 innings against Milwaukee. Through two June outings, the 28-year-old has compiled a 2.31 ERA and a 15-to-3 strikeout-to-walk ratio in 11.1 innings. Xander Bogaerts (2-for-11) and Jackson Merrill (0-for-4) are among San Diego’s batters who have struggled against May.

The Padres are expected to start Lucas Giolito, who does not inspire a ton of confidence. The right-hander is saddled with a 4.35 ERA and an especially atrocious 1.74 WHIP. Giolito’s road ERA is 6.94.

Over 8.5 (-115)

San Diego has scored 22 runs over the past four outings. Fernando Tatis Jr. is on a five-game hitting streak that features three multi-hit efforts – including four hits last Tuesday against Cincinnati. Samad Taylor is on a seven-game hitting streak and went 3-for-5 with a homer on Saturday during a 9-3 victory over Baltimore.

May is a solid starter, but he has worked more than 6.0 innings only once this whole season. That means the Cardinals’ reliever will likely see plenty of work on Monday, which is not great news for the home team. They come in with a 4.21 bullpen ERA for the year.

The over is 6-1 in the Padres’ last seven games. It is also 3-1-1 in the Cardinals’ last five overall and 4-1 in their last five at home. Another relatively high-scoring affair could be in the cards.

Jordan Walker Over 1.5 Hits, Runs and RBIs (-160)

Jordan Walker’s torrid 2026 campaign has continued with a stellar month of June. The Cardinals’ right fielder has hit safely in 10 of the last 11 games, a stretch that features five multi-hit performances. He has homered in three of the last eight contests, pushing his total to 18 for the year. Walker has also recorded eight RBIs over the past five outings.

A righty-against-righty matchup with Giolito should not be of any concern. Walker is batting .299 off right-handers this season compared to .277 when he faces a southpaw.
