Recent developments favor Baltimore after a 13-1 rout on August 25 powered by Pete Alonso’s extra-base surge and strong road form (12-8 in their last 20 away games). The Cardinals, hampered by injuries including Masyn Winn’s thumb placement on the IL plus elbow and forearm issues in their rotation, have dropped recent contests and show vulnerability against power hitting. Probable starters like Chris Bassitt (post-IL return) versus Matthew Liberatore highlight ERA concerns near 5.00 for both clubs, with bullpen depth and lineup adjustments remaining pivotal for the remaining games.
