Walker (hamstring/knee) will return to the lineup Saturday against the Braves, Jordan McPherson of the Miami Herald reports.

Walker (hamstring, knee) is on the bench again for Friday's game against Atlanta, Jordan McPherson of the Miami Herald reports.

Walker (hamstring, knee) is not in the lineup Wednesday against the Indians, Andre Fernandez of The Athletic reports.

EDGE Analysis

Walker will remain on the bench for a fifth straight game as he continues to nurse minor hamstring and knee injuries.

Martin Prado is starting at first base in place of Walker on Wednesday.

Walker (hamstring) had an MRI on his left knee Tuesday which revealed a bone bruise, Joe Frisaro of MLB.com reports.

EDGE Analysis

Walker has been out of the lineup for four straight games with what had been called a hamstring injury. It's unclear if the knee bruise is a new diagnosis or an entirely separate issue. Either way, the injury isn't considered to be too serious, and he'll be available to pinch hit Tuesday.

EDGE Analysis

Walker is in line to miss his fourth straight contest due to a hamstring injury. He's already been used off the bench twice since suffering the injury, so he should be available to pinch hit Tuesday night if needed. Garrett Coopers draws the start at first base and will hit sixth with Walker out of the mix.

Walker's absence from the lineup for Saturday's game against the Phillies is due to a hamstring issue, Jordan McPherson of the Miami Herald reports.

EDGE Analysis

The injury explains why Walker is sitting for the second straight game against right-handed pitching. He's expected to sit again Sunday but could return after Monday's off day. The injury doesn't appear to be particularly serious, as he's available to pinch hit, as he did in Friday's game.

Walker sits for the second straight game Saturday against the Phillies, Jordan McPherson of the Miami Herald reports.

EDGE Analysis

Walker sat against a righty for the first time this season Friday and will do so again with Jake Arrieta on the mound Saturday. It's odd timing for a loss of at-bats, as he's gone 7-for-14 with three doubles in his last five games. It's possible he's carrying an unreported minor injury, though he did appear off the bench Friday. Miguel Rojas starts at first base in his absence.
