The read
PNC Park gets another July game that feels like the playoffs. After Monday night’s walk-off, Pittsburgh can lock up the season tiebreaker. Both teams have the same record, and with the trade deadline just days away, I care more about tonight’s matchup than momentum.
I give Bubba Chandler the edge among the starting pitchers. He has pitched better than his results suggest, his fastball and slider are hard to hit, and he just kept the Yankees scoreless for more than six innings. Arizona’s left-handed hitters are a threat, but Brandon Pfaadt has had real trouble with lefties. Pittsburgh can go after him with Brandon Lowe, Ryan O’Hearn, Jacob Gonzalez, its hitters who bat from either side, and a cleared Esmerlyn Valdez.
I also trust Pittsburgh more late in the game. Mason Montgomery probably needs the night off, but Gregory Soto is available. Arizona has fewer dependable relief options after Jonathan Loáisiga pitched on back-to-back days, and its closer role is less settled. Chandler could be pulled early if he struggles, so I’m not betting heavily, but with the odds close to even, I’m taking the Pirates to win.
The full analysis
PNC Park gets another game with October weight in July, and Pittsburgh can clinch the season tiebreaker after Monday night’s walk-off. With both clubs 55-52 and the deadline three days away, this is less about momentum than which side is better built for tonight’s specific matchup.
I give Bubba Chandler the starting-pitching edge. His 4.01 xERA is better than his 4.47 ERA, his 98.6 mph four-seamer and 90.3 mph slider both miss bats, and he just held the Yankees scoreless for 6 1/3 innings. Arizona’s left-handed bats are the danger, but Brandon Pfaadt presents the more direct weakness: lefties own an .856 OPS against him, and Pittsburgh can attack him with Brandon Lowe, Ryan O’Hearn, Jacob Gonzalez and its switch-hitters ahead of a cleared Esmerlyn Valdez.
The late innings also lean Pittsburgh. Mason Montgomery likely needs a night off, but Gregory Soto remains available; Arizona is thinner in leverage after Jonathan Loáisiga worked on consecutive days, and its closer situation is less secure. Chandler’s occasional short leash keeps this from being a heavy play, but at a near pick’em price I make the home side the right favorite. My bet is Pirates moneyline -115.

Props on this game
3Gabriel MorenoOVER 1.5 H+R+RBI H+R+RBI-123
WActual 4
Moreno is 16-for-40 over his last 15 days and has cleared this combination in 11 of his last 15 games. Chandler throws his four-seamer almost half the time, and Moreno owns a .333 average, .569 slugging percentage and .491 expected wOBA against four-seamers this season. Hitting third gives him both RBI opportunities and strong protection behind him.
Geraldo PerdomoOVER 0.5 Walks Walks-113
Not yet graded
Perdomo has drawn a walk in 10 of his last 15 games, and his recent 16% chase rate and 9% whiff rate show how well he is controlling the zone. Chandler has allowed at least two walks in six of his last eight starts. Batting second should give Perdomo four or five chances to work one at close to even money.
Endy RodriguezOVER 0.5 Home Runs Home Runs+800
LActual 0
Rodriguez gets the favorable side of Pfaadt’s pronounced platoon split. Left-handed hitters have a .304 average and .856 OPS against Pfaadt with seven home runs in 138 at-bats, while Rodriguez has produced a .313 average, .996 OPS and all five of his homers against right-handed pitching. He has also slugged .719 against four-seam fastballs, a pitch Pfaadt throws frequently without generating many whiffs. Batting seventh and playing at PNC Park lower the volume, but +800 requires only an 11.1% hit rate and gives me enough compensation for those concerns.
