The St. Louis Cardinals visit PNC Park to clash with the Pittsburgh Pirates on June 30, 2025, with both teams in differing situations. The Cardinals, at 47-38, have had a commendable season, while the Pirates are lagging at 35-50. This National League Central confrontation is vital for the Cardinals as they strive to enhance their playoff position.

The Cardinals maintained their momentum with a win in their recent game. Erick Fedde, a right-hander who has faced challenges this season, is expected to start for them. With a 4.11 ERA and a projected 5.4 innings, Fedde may exploit the Pirates’ 29th-ranked offense. His ability to keep the ball in play could be advantageous against Pittsburgh’s hitting struggles.

The Pirates will counter with Andrew Heaney, a left-hander with an average 4.48 ERA. Heaney’s season has been marked by inconsistency, projecting 5.5 hits and 2.8 earned runs per game. With both pitchers potentially underperforming, offensive output might be the game’s deciding factor.

The Cardinals, ranked 15th in MLB offense, should leverage this against the Pirates, who are ranked 29th. The game’s total stands at 8.5 runs, indicating a possibly tight, low-scoring contest. Betting trends favor the Cardinals against the struggling Pirates.

Quick Takes St. Louis Cardinals:

Erick Fedde, an extreme flyball pitcher (34.7% FB% as per THE BAT), may benefit from pitching in the 28th HR venue in MLB during this matchup.

His skill set aligns well with today’s park, possibly leading to enhanced performance.

Hitters like Nolan Arenado, who hit many groundballs, may see diminished performance against groundball-inducing pitchers like Andrew Heaney.

This interaction between swing plane and pitch trajectory can lead to reduced performance and missed potential value.

The St. Louis Cardinals might experience negative regression in future games, as they are deemed the 10th-luckiest offense by THE BAT X.

Teams outperforming their projected talent might be overvalued, leading to potential underperformance ahead.

Quick Takes Pittsburgh Pirates:

Andrew Heaney has cut his slider usage to 15.7% this season from 27.9% last year.

Sliders are effective, and reducing reliance on them could hinder success, especially if replaced with more fastballs.

Joey Bart is slated 6th in the lineup, a drop from his usual top-half position.

Batting lower reduces plate appearances and potential to hit Over markets. This misplacement might offer value opportunities.

Pirates’ batters rank among the worst in MLB, with an 89.1-mph average exit velocity.

Hitting harder increases chances for home runs or ball landing in fair territory before a fielder can react.
