Cubs vs. Pirates Prediction: Taillon’s Struggles Face a Hot Pittsburgh Lineup

Jameson Taillon returns to PNC Park still searching for the form that made him a Pirates workhorse, and Pittsburgh’s lineup is exactly the kind of group that can make a rough month even rougher.

Quick take:

• Pick: Pirates -1.5
• Why: Braxton Ashcraft’s strikeout stuff and a rested Pittsburgh bullpen against a Cubs starter who’s allowed a 6.00 ERA over his last seven outings
• The number to watch: Taillon’s 1.45 WHIP over his last seven starts

Sunday’s series finale closes out a weekend set with real stakes buried under the surface. The Cubs (58-45) are chasing a playoff position in a stacked NL Central, while the Pirates (53-51) are trying to prove their recent surge is more than a mirage against a fading division leader from Milwaukee. Taillon spent his first four big-league seasons in Pittsburgh before being dealt to the Yankees ahead of 2021, and every trip back to PNC Park still carries a little extra juice for the right-hander, even in a season that hasn’t gone his way.

What the Market Is Saying

Sportsbooks have installed the Pirates as home favorites, with DraftKings pricing Pittsburgh at -126 on the moneyline and Chicago going off at +104. The run line has Pittsburgh at -1.5 (+163) and the Cubs at +1.5 (-199), while the total sits at 8.5 runs. That’s a notable line move in Pittsburgh’s favor for a team that’s been an underdog in nearly half its games all season — a sign oddsmakers are leaning heavily on the pitching matchup rather than season-long resume. Pittsburgh has actually won 59.6% of the games it’s been favored in this year, a stronger clip than that reputation for scrappy underdog baseball suggests, while the Cubs have cashed in 56.3% of their own turns as the favorite. Neither club is unfamiliar with either role, which is part of what makes Sunday’s number worth a second look before kickoff. Bettors comparing this line against the rest of the day’s slate can check live MLB odds for how the market is shaping up elsewhere on the board.

Recent Form

Both clubs arrive with some momentum, but the Cubs’ has been far more emphatic — Chicago has won 8 of its last 10 to Pittsburgh’s 6 of 10, and Chicago’s run differential over that stretch dwarfs the Pirates’.

Taillon’s Rough Stretch Meets a Pirates Lineup That’s Heating Up

Taillon is 2-5 with a 5.19 ERA this season, and the trend line is pointing the wrong direction — over his last seven starts he’s 0-4 with a 6.00 ERA and a bloated 1.45 WHIP, giving up 38 hits in 33 innings. That’s a pitcher a hot lineup can feast on, and Pittsburgh has one right now. Nick Gonzales has been the engine of it, hitting .377 with a .500 OBP over his last 15 games while playing all over the infield. Bryan Reynolds, meanwhile, remains PNC Park’s most dangerous bat at .282 with 13 home runs, 56 RBI and an .867 OPS, giving Pittsburgh thump in the middle of the order to pair with Gonzales’ recent surge at the top.

Ashcraft gives Pittsburgh the far steadier arm in this one. His 3.95 ERA and 10.1 strikeouts-per-nine mark him as a legitimate swing-and-miss threat, and against a Cubs lineup that’s chasing a playoff spot but hasn’t hit lefties or pitchers who work off the fastball particularly well recently, that matters.

Taillon has allowed 38 hits in his last 33 innings pitched — nearly one and a half baserunners an inning against him over his last seven starts.

That kind of command slippage is hard to hide against a Pittsburgh lineup missing Oneil Cruz and Spencer Horwitz but still getting enough from Reynolds, Gonzales and a healthy Jared Triolo to make contact-heavy pitchers pay. Chicago’s counter is its own recent hot streak, and if the Cubs’ bats travel the way they have the last two weeks, this could turn into the kind of high-scoring affair the 8.5 total suggests bettors expect.

Pittsburgh’s rotation depth is also quietly better than its overall record indicates. Ashcraft has emerged as a legitimate mid-rotation piece behind ace Paul Skenes, and manager Don Kelly has leaned on a bullpen that’s held up despite losing Wilber Dotel and Chris Devenski to injury for long stretches. The Cubs, meanwhile, are still adjusting their rotation order around Taillon’s struggles, and Chicago’s front office will be watching this start closely for signs the right-hander needs a longer look before his next turn. For bettors who like to shop for value, checking a betting calculator before locking in the run line is a smart habit on a number that’s moved as much as this one has since Friday.

Prediction and Best Bet

Ashcraft’s edge on the mound and Pittsburgh’s recent offensive life at home make the Pirates the play in the series finale, especially with Taillon trending in the wrong direction at exactly the wrong time.

The pick:

1. Prediction: Pirates 6, Cubs 3
2. Best Bet: Pirates -1.5

Fade the recent Cubs win streak this once — Taillon’s command problems are too real to ignore, and Pittsburgh has too many bats going right now to leave in a series finale at home.
