San Diego Padres

On April 30, 2025, the San Diego Padres will host the San Francisco Giants at Petco Park in a crucial National League West matchup. Both teams are having solid seasons, with the Padres at 18-11 and the Giants slightly ahead at 19-11. This game marks the second contest in their series, with the Giants winning the first matchup recently.

Starting for the Padres will be Michael King, who has been excellent this season, boasting a 3-1 record and a stellar 2.18 ERA. According to advanced-stat Power Rankings, he ranks as the 16th best starting pitcher in MLB, indicating he’s a top-tier option on the mound. However, King has some concerning peripheral stats, as his 3.24 xFIP suggests he’s benefitted from some luck and might struggle to maintain his current success. He projects to pitch about 5.8 innings while allowing 2.0 earned runs, with a striking average of 7.2 strikeouts per game.

The Giants will counter with Landen Roupp, who has posted a 2-1 record and a 4.56 ERA this season. Roupp ranks 69th among starting pitchers, which still places him above average. However, his 27.4% strikeout rate will be tested against the Padres, who have the lowest strikeout rate in the league. This matchup may present an opportunity for the Padres to capitalize on Roupp’s high-strikeout tendencies.

While the Padres feature the 13th best offense by their underlying talent metrics, they shine in batting average, sitting 5th in the league. Yet, they rank low in home runs, which could limit their scoring potential in a game total set at a very low 7.0 runs. San Diego’s bullpen excels, rated 2nd in MLB, which could be pivotal if the game remains close late on. The Padres are currently favored at -135, indicating confidence in their ability to win this matchup at home.

San Francisco Giants Insights

• Landen Roupp – Over/Under 4.5 Strikeouts (-120/-110)
  Landen Roupp’s high utilization rate of his secondary pitches (59.2% this year) should work in his favor considering they are generally much more effective than fastballs.
  Explain: A pitcher who limits has fastball usage will instead heavily use change-ups, curveballs, sliders, etc. These are far more effective pitches at preventing runs and generating strikeouts.
• Heliot Ramos – Over/Under 0.5 Hits (-160/+125)
  Heliot Ramos is projected to hit 6th on the lineup card in this matchup, which would be a downgrade from his 84% rate of hitting in the top-half of the batting order this season.
  Explain: The lower in the order a player bats, the fewer plate appearances he will get and the fewer opportunities he will get to hit the Over for every market. A player who hits lower in the order than he normally does may provide extra value opportunity since the market may be based on him hitting higher.
• San Francisco Giants – 2H Moneyline
  According to the leading projection system (THE BAT), the San Francisco Giants’ bullpen projects as the 5th-best out of all teams in the majors.
  Explain: Most bettors only consider the starting pitcher, but a strong bullpen sneakily creates a tougher matchup for the opposing offense and suppresses a game’s runs.

San Diego Padres Insights

• Michael King – Over/Under 6.5 Strikeouts (-130/+100)
  Michael King’s fastball spin rate has increased 100 rpm this season (2386 rpm) over where it was last year (2286 rpm).
  Explain: Spin rate is a key component to fastball success in generating strikeouts and preventing runs, so a pitcher who improves his spin rate will likely see improved results.
• Jason Heyward – Over/Under 0.5 Total Bases (-115/-115)
  The San Francisco Giants have just 1 same-handed RP in their bullpen, so Jason Heyward can likely count on never losing the platoon advantage against the ‘pen all game.
  Explain: Hitters perform worse against pitchers of the same handedness (i.e. righty-vs-righty), and being able to avoid those matchups against the bullpen boosts performance and creates hidden edge.
• Manny Machado – Over/Under 1.5 Total Bases (+130/-170)
  Manny Machado hits a lot of his flyballs to center field (39.9% — 97th percentile) and sets up very well considering he’ll be hitting out towards the league’s 2nd-shallowest CF fences in today’s game.
  Explain: This player’s skill set matches up particularly well with the park he’s in today, which may lead to better-than-usual performance.
