Andrew Abbott has a 3.92 ERA. Matthew Boyd has a 4.31. So why does our model make the visiting Cubs the favorite on the strength of the pitching matchup? Because The Call doesn’t read ERAs — it reads what’s underneath them, and underneath, this matchup flips completely: Boyd’s FIP is 3.27, Abbott’s is 4.91. One of these lines is lying, and Sunday at Great American Ball Park we find out which.
The stakes are real on both sides. The Cubs are 52-42, seventh on our Elo board at 1521, but they’ve dropped two straight. The Reds are 43-50 and playing spoiler at home in a divisional finale.
What The Call sees
The Call has the Cubs at 55% — enough to overcome home field, which is the tell for how strongly the model likes the pitching card. The Elo gap (1521 vs. 1476, No. 7 vs. No. 24) sets the base, and the Boyd-Abbott matchup adds a 13.1-point adjustment toward Chicago, one of the larger pitcher swings on the weekend board. Cincinnati’s 4-6 form over the last ten doesn’t help the home case either.
What could break the pick
The catch: the arm the model trusts is attached to a surgically repaired knee. Boyd — an All-Star in 2025 — hadn’t pitched in a big-league game between May 3 and late June after tearing his meniscus and undergoing surgery, per the Chicago Sun-Times. He returned June 25 against the Mets, and the Cubs have kept him under 80 pitches while he builds back up. He’s been effective in the small sample, and manager Craig Counsell’s staff has made no secret of what he means to an injury-thinned rotation — “That’s our ace,” as the Sun-Times headline put it.
But a capped pitch count changes the math. If Boyd gives you five strong and hands it to the bullpen in a one-run game, Cincinnati gets the exact late-inning coin flip our 55% number can’t protect. And Abbott’s 3.92 ERA isn’t fake to the hitters he’s retired — he’s kept runs off the board all season at home. FIP says regression; regression doesn’t always arrive on schedule.
