Alex Call's recent performance has been a highlight for the Nationals as he made a spectacular diving catch in a game against the Giants, contributing significantly with two singles and a run. Meanwhile, Pete Crow-Armstrong of the Cubs has shown flashes of potential despite a challenging batting average of .205, emphasizing his speed with 22 stolen bases this season. His defensive skills remain elite, ranking highly among MLB center fielders, which gives the Cubs hope for his continued development at the plate. Luis Garcia Jr. of the Nationals appears to have turned a corner, boasting a .290 batting average and strong offensive metrics after struggling earlier in the season, indicating growth in his role. Despite his recent success, Garcia's expected stats suggest he might still have room for improvement. Overall, both teams are seeing promising developments in their young players as they navigate the latter part of the season.
