San Francisco Giants

On April 4, 2025, the San Francisco Giants will host the Seattle Mariners at Oracle Park for the first game of their interleague series. The Giants are riding high with a 5-1 record this season, showcasing a solid start, while the Mariners are struggling at 3-4, looking to find their footing. In their last outing, the Giants defeated the San Diego Padres 6-3 on April 2, while the Mariners edged out the Kansas City Royals 3-2 in a tighter affair.

The matchup features two right-handed pitchers: Justin Verlander for the Giants and Luis Castillo for the Mariners. Verlander, currently ranked as the 82nd best starting pitcher in MLB, has shown promise with a 3.60 ERA this season and projects to pitch an average of 5.5 innings, allowing 2.3 earned runs. His ability to limit walks (4.6 BB%) could be crucial against a Mariners lineup that tends to draw walks, as Verlander’s control might mitigate this strength.

On the flip side, Castillo’s projections are less favorable. He has struggled this year, with projections indicating he will only pitch about 4.8 innings while surrendering 3.0 earned runs. The Mariners’ offense ranks as the 45th best in MLB, reflecting their difficulties at the plate, particularly in power categories where they sit 31st in home runs.

While the Giants’ offense has its own issues, ranking 31st in the league, their bullpen stands out as the best in MLB according to Power Rankings, which could provide a significant advantage late in the game. Given the current odds, the Giants are favored with a moneyline of -150, indicating confidence in their ability to secure a win against the struggling Mariners.

Seattle Mariners Insights

• Jorge Polanco – Over/Under 0.5 Hits (-135/+105)
  Jorge Polanco has primarily hit in the back-half of the batting order this year (75% of the time), but he is projected to hit 5th on the lineup card in today’s game.
  Explain: The higher in the order a player bats, the more plate appearances he will get and the more opportunities he will get to hit the Over for every market. A player who hits higher in the order than he normally does may provide extra value opportunity since the market may be based on him hitting lower.
• Luis Castillo – Over/Under Strikeouts
  According to the leading projection system (THE BAT), Cal Raleigh (the Mariners’s expected catcher today) projects as an elite pitch framer.
  Explain: Pitch framing is a catcher’s ability to make a ball look like a strike to the umpire, “stealing” strikes for his pitcher. This leads to more positive outcomes (like strikeouts) and fewer negative ones (like walks or earned runs).

San Francisco Giants Insights

• San Francisco Giants – 1st Five Innings (F5) Moneyline (-160)
  Justin Verlander is an extreme flyball pitcher (43.3% FB% per the leading projection system, THE BAT) and should be aided by pitching in the #26 HR venue among all parks in today’s game.
  Explain: This pitcher’s skill set matches up particularly well with the park he’s in today, which may lead to better-than-usual performance.
• San Francisco Giants – 2H Moneyline
  According to the leading projection system (THE BAT), the San Francisco Giants’ bullpen grades out as the best among all major league teams.
  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.
