Team Analysis

Chicago Cubs

The Cubs’ 4-1 record in their last five games, with 4.2 runs per outing, highlights a team finding rhythm at the right time. Pete Crow-Armstrong has been a reliable run producer, and when paired with Seiya Suzuki’s steady contributions, the offense has the balance needed to exploit Pittsburgh Pirates’ pitching. Their 40-35 road record reveals resilience away from home, a key factor when weighing this matchup.

Michael Busch adds another layer of depth to an order that has been consistently above league average in power production, giving Chicago multiple ways to generate runs. With a 6-4 record over their last ten, the Cubs have maintained steady form, avoiding prolonged slumps. That consistency, paired with their ability to outscore opponents on the road, positions them as the more reliable betting side.

Pittsburgh Pirates

The Pirates’ 1-4 record across their last five games, with only 3.0 runs per contest, reflects a lineup struggling for timely hits. Bryan Reynolds has been the most reliable bat, but the lack of consistent support means opponents can pitch around him. Despite a respectable 42-34 home record, the current stretch of form neutralizes that advantage.

Andrew McCutchen and Tommy Pham have provided occasional sparks, but the Pirates’ 1-9 skid in their last ten games makes it clear the offense is stuck in neutral. At just 2.3 runs per game in that span, production has fallen well below competitive levels. Until the lineup strings together sustained rallies, Pittsburgh remains a fade candidate in this spot.

  • Batting Average: 0.23
  • Total Runs Scored: 540
  • Home Runs: 107
  • OBP: 0.305
  • SLG: 0.348
