Miami Marlins vs Philadelphia Phillies Prediction – 4/19/2025

Miami Marlins vs Philadelphia Phillies Betting Preview

On April 19, 2025, the Philadelphia Phillies will host the Miami Marlins at Citizens Bank Park for the second game of their series. The Phillies, currently sitting at 12-8, are enjoying a strong season, while the Marlins lag behind with a record of 8-11. In their last outing, the Phillies showcased their offensive prowess, taking down the Marlins with a convincing win that highlighted their ability to capitalize on scoring opportunities.

The matchup on the mound features Taijuan Walker for the Phillies, who has an impressive 2.30 ERA this season, despite being ranked as the 285th best starting pitcher in MLB according to advanced stats. Walker has shown flashes of brilliance, though his 4.11 xFIP suggests he may have benefited from some luck early on. He projects to pitch around 5.4 innings while allowing approximately 3.0 earned runs, though he has struggled with walks, averaging 1.7 per outing.

On the other side, the Marlins will counter with Cal Quantrill, who has also struggled this season with a 5.79 ERA and a high walk rate of 9.8%. While his 4.59 xFIP indicates he might improve, he projects to allow 3.4 earned runs over 5.1 innings, which could be problematic against a Phillies lineup that ranks as the 11th best in MLB offense.

Given the Phillies' strong hitting and Walker's ability to limit damage, they enter this game as significant favorites, with a moneyline of -205, suggesting they could exceed their implied team total of 5.83 runs. Meanwhile, the Marlins will need to find a way to overcome their offensive deficiencies—ranking 27th in home runs—to keep pace in this matchup.

Quick Takes Miami Marlins:

Despite conventional wisdom, fastballs are generally a pitcher's least effective pitch. Cal Quantrill has used his secondary offerings 12.7% more often this season (72.5%) than he did last year (59.8%).

• 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.

Otto Lopez is projected to hit 8th in the lineup in this matchup, which would be a downgrade from his 89% rate of hitting in the top-half of the lineup this year.

• 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.

According to the leading projection system (THE BAT), the Miami Marlins' bullpen ranks as the 3rd-worst among all the teams in the league.

• Most bettors only consider the starting pitcher, but a weak bullpen sneakily creates an easier matchup for the opposing offense and boosts a game's runs.

Quick Takes Philadelphia Phillies:

Taijuan Walker's 2094-rpm fastball spin rate since the start of last season ranks in the 16th percentile out of all starting pitchers.

• Spin rate is a key component to fastball success in generating strikeouts and preventing runs.

Bryce Harper is likely to have the upper hand against every reliever for the whole game, since the bullpen of the Miami Marlins has just 1 same-handed RP.

• 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.

Bryce Harper has a 94th percentile opposite-field rate on his flyballs (38%) and is a great match for the park considering he'll be hitting them out towards the game's 9th-shallowest LF fences in today's matchup.

• This player's skill set matches up particularly well with the park he's in today, which may lead to better-than-usual performance.
