The San Diego Padres will be looking to keep their winning ways alive tonight in the series opener against the St. Louis Cardinals at Busch Stadium.
However, due to Lucas Giolito's struggles, my Padres vs. Cardinals predictions are eyeing the hosts to capitalize on the righty's inability to limit baserunners.

Who will win Padres vs Cardinals today: Cardinals moneyline (-140)
San Diego Padres starter Lucas Giolito has made just five appearances this season since signing late, and the underlying metrics are concerning. The veteran sports a 6.40 xERA overall while walking 7.84 hitters per nine innings.
Across his last two appearances, Giolito has lowered his xERA to 4.38, but command remains a major problem as he's still issuing 6.75 free passes per nine innings. That's a dangerous profile against a St. Louis Cardinals lineup that owns an impressive 132 wRC+ over the last 14 days and a .369 wOBA across its previous six contests.
Dustin May also enters tonight's start in good form. The right-hander has settled down lately, compiling a stellar 1.94 FIP over his last four appearances while limiting opponents to a 34.5% hard-hit rate during that span.
St. Louis will create opportunities against Giolito, while May is well-positioned to continue his recent success.
I'll play this pick up to -150.
COVERS INTEL: May is striking out 11.63 hitters per nine innings over the last month compared to 8.17 K/9 overall this season. 
Padres vs Cardinals Over/Under pick: Under 8.5 runs (-110)
The Cardinals' bullpen hasn't been amazing lately, posting a 5.02 xERA over the last week, but May typically pitches relatively deep into games and has worked into the sixth inning in two of his last three starts. That limits the amount of bullpen exposure against a Padres lineup that is batting just .224 on the road and owns an 89 wRC+ away from home.
On the other side, San Diego's bullpen has been excellent lately, posting a stellar 2.94 FIP across its last 24 2/3 innings while allowing only 0.73 home runs per nine. The Padres' relievers have also generated a 50% ground-ball rate during that stretch, another encouraging sign for the Under.
St. Louis should have their chances to score against Giolito, but the Padres' bullpen success could help prevent the game from turning into a high-scoring affair. With May capable of providing length and both offenses carrying some limitations, this game profiles as a relatively low-scoring affair.
