The case for Miami Marlins

Late-inning bullpen advantage
Pittsburgh Pirates relievers have a 3.04 ERA over the last 7 days; Miami Marlins relievers have a 2.86. If this is still close after six innings, that gap favors Miami Marlins.

The case for Pittsburgh Pirates

Starting pitcher edge: Pittsburgh Pirates
LyDia gives Braxton Ashcraft a 10-point edge over Tyler Phillips, driven mainly by K-BB% (20.7% vs 7.9%) and expected innings (5.8 vs 4.2).

Why it is not official

Below the 61.0% official gate
Win probability is 58.9%. LyDia does not make a game official below 61.0%, no matter how good the price is. This is a value spot, not a high-confidence winner.
Setup quality below the bar
Lab Rating is 5.3/10, under the 8.0/10 required for an official pick.
Pitcher edge points the other way
LyDia gives Braxton Ashcraft a 10-point edge over Tyler Phillips, driven mainly by K-BB% (20.7% vs 7.9%) and expected innings (5.8 vs 4.2). That is not the side the model likes here — when the model and the mound disagree, tread carefully.

Pitcher edge: LyDia gives Braxton Ashcraft a 10-point edge over Tyler Phillips, driven mainly by K-BB% (20.7% vs 7.9%) and expected innings (5.8 vs 4.2).

How to read this: the scorecards above name the starters; every number lives in this table. Highlighted cells mark a gap big enough to matter. K% and BB% are strikeout and walk rate as a share of batters faced -- K-BB% is the two combined into one skill number. HR/9 is home runs allowed per nine innings. Ground-ball and fly-ball rate are neither good nor bad on their own: high ground-ball pitchers trade strikeouts for double plays and fewer home runs, and on this data source the two rates are complementary (they add to 100%), not independent reads.

Over the last 30 days the Marlins have been the better offense, 0.309 wOBA to 0.285. They are cooling off against their own season line (-0.014 wOBA). Pirates are striking out at 26.2% over the window — something the opposing starter can lean on.

Risk is what the model actually uses: fatigue blended with how well the pen has pitched. High fatigue with high efficiency is a tired pen that is still getting outs.
