The home run was Walker's first in the majors since 2014, when he received a cup of coffee with the Orioles. Prior to being promoted to the big club earlier this moth, Walker displayed major power with 32 home runs and 75 extra-base hits for Triple-A Reno, but his contact issues have thus far from prevented him from gaining much traction at the big-league level. It's unlikely that Walker will pick up consistent at-bats over the final week and change of the regular season with the Diamondbacks aiming to solidify playoff positioning.
He now has 39 homers on the season, setting a new National League rookie record in the process. Bellinger won't be limping into the playoffs either, as he's posted a .291/.378/.595 slash line in September with five home runs and 15 RBI in 21 games.
The Cardinals don't return home until Monday, so expect Martinez to miss at least the remainder of this weekend's series against the Pirates no matter how good the news is. With just over a week left in the season, even a strain could put an end to Martinez's campaign.
Martinez was 0-for-2 with a pair of walks when he left the game. He owns a .309/.376/.516 batting line and the Cardinals will need his bat if they are going to make a last-ditch run to the postseason. Consider him day-to-day for now.
Jones will give way to Pablo Sandoval at third base for a second straight game. This absence comes as no surprise, as the Dodgers are starting lefty Rich Hill, but Wednesday's absence was against a right-hander and that suggests the team is backtracking on its plan to give Jones more starts down the stretch. Jones is batting just .139/.205/.167 and has struck out 21 times in 36 at-bats so far in September.
Zimmerman receives a day off following six straight starts, going 8-for-24 (.333 average) with three home runs and eight RBI during that span. In his place, Adam Lind will draw the assignment at first base, while batting cleanup.
Carpenter exited Thursday's contest after fouling a ball off his foot, although it didn't seem overly serious at the time. As expected, the 31-year-old is in the lineup for the series opener against Cincinnati, while batting leadoff and manning the hot corner.
Adams remains limited with a hamstring issue that has sidelined him for almost two weeks now. The 29-year-old has only been able to record two plate appearances, both coming as a pinch hitter, since suffering the setback Sept. 10.
Harrison Bader pinch hit for Carpenter in a close game, so his ailing foot likely had a part to play in the veteran exiting before the game's conclusion. It remains to be seen if this is an issue that will linger, but he should be considered day-to-day for now.
Adams' hamstring injury continues to linger, so he'll stick on the bench for another game as Lane Adams draws the start in left field. He's been able to make a couple of pinch hit appearances since injuring his hamstring Sept. 10, but it's still unclear when he'll be able to rejoin the starting nine.
