Cubs vs. Cardinals Prediction, Winner Payout, Over/Under – Monday, July 27

To get the series underway on Monday, it will be Cubs SP David Peterson (4.36 xFIP across 89.0 IP), while the Cardinals had yet to determine a starter as of Monday morning.

Over his 12 starts and 8 relief appearances, Peterson is in the 14th percentile in xERA (5.26) and eighth percentile in xBA (.279), per Baseball Savant. He also isn’t much of a swing-and-miss pitcher, as he ranks in the 35th percentile in chase rate (29.0%), 22nd percentile in whiff rate (21.5%), and 19th percentile in strikeout rate (18.2%).

On both the Cubs and the New York Mets, Peterson has experienced rough outings, but he’s given up a combined 1 ER across his last two starts.

Although the Cardinals haven’t announced a starter, SP Matthew Liberatore (4.31 xFIP across 99.0 IP) would be the projected starter if we’re going by the same date as Peterson for their last starts.

Along with beating the Pittsburgh Pirates in a three-game series over the weekend, the Cubs have produced the second-best wRC+ (122), third-best wOBA (.349), and second-best ISO (.192) over the last 30 days, per FanGraphs.

On top of the Cardinals losing three straight series, they’ve posted the third-worst wRC+ (74), wOBA (.277), and ISO (.117) in the same sample.

Ahead of Monday’s matchup, Chicago has the fifth-lowest payout to make the playoffs (1.07x) with a 59-46 record, while St. Louis has the 11th-highest payout (4.76x) in the same market with a 53-52 record.
