The Los Angeles Dodgers have experienced success recently, winning 8 of their last 10 games, despite All-Star first baseman Freddie Freeman missing time due to a fractured finger. Freeman is expected to return for a crucial series against the Diamondbacks after a brief recovery. Meanwhile, Phillies pitcher Taijuan Walker has been demoted to the bullpen after struggling with a 6.50 ERA this season, having allowed 18 home runs, which contributed to the team's 0-9 record in his last nine starts. In contrast, Dodgers pitcher Yoshinobu Yamamoto is on track to return from injury, having performed well during rehab, showcasing a 2.92 ERA prior to his triceps injury. Additionally, Astros reliever Rafael Montero, who has struggled in the majors, may be promoted from Triple-A after posting impressive stats in his recent minor league outings. The upcoming weeks will be pivotal for these players as they contribute to their teams' postseason aspirations.
