Walker is Jordan McPherson of the Miami Herald against the Phillies, source reports.

EDGE Analysis

Walker had started against every righty while sitting against every lefty so far this season, but that trend ends Friday, with Walker on the bench against righty Jerad Eickhoff. Martin Prado gets the start at first base.

Walker went 3-for-5 with two doubles and a run scored in Thursday's extra-inning win over the Phillies.

EDGE Analysis

His second-two bagger was the big one -- with two outs in the top of the 10th inning. Walker just missed a homer with a hit off the top of the wall in the left-field corner, then scored when Starlin Castro actually did go yard. Walker is on a bit of a roll, going 7-for-14 with three doubles and three walks over the last four games, but the 33-year-old has almost no production to show for it -- Thursday's run was the only time he's crossed the plate during the hot streak, and he hasn't collected an RBI.

Walker is not in the lineup Wednesday against the Cubs.

EDGE Analysis

Walker will sit for a second straight game with another left-hander in Cole Hamels starting for the opposition. Martin Prado will take over at first base in his stead, hitting second.

Walker is out of Tuesday's lineup against the Cubs, Joe Frisaro of MLB.com reports.

EDGE Analysis

Walker will head to the bench for the second game of the series with lefty Jose Quintana slated to toe the rubber for the opposition. Martin Prado draws the start at first base and will bat fifth in Walker's stead.

Walker went 2-for-5 with a solo home run in Saturday's win over the Phillies.

EDGE Analysis

The veteran is only hitting .190 through 15 games, and while he does have three homers, all three have come with the bases empty and he has no other RBI. The Marlins aren't exactly flush with quality big-league bats, so Walker's job at first base may be safe for now, but if he continues to struggle the club may look elsewhere for offensive help.

Walker went 1-for-3 with a solo home run and a walk Wednesday against the Reds.

EDGE Analysis

Walker took Tyler Mahle deep in the third inning, accounting for the entirety of the Marlins' offensive production. It was his second homer of the season, but his first since Opening Day. There's been little to note about Walker's early season production as he has just two RBI and four runs scored through 34 plate appearances.

Walker is not in the lineup for Sunday's game against Atlanta, Joe Frisaro of MLB.com reports.

EDGE Analysis

Walker started the last three games but will return to the bench with Atlanta sending out left-hander Sean Newcomb. Martin Prado grabs another start as the first-base platoon continues.

Walker is on the bench Tuesday against the Mets.

EDGE Analysis

Walker sits for the fourth time in six games as the Marlins face yet another lefty in Jason Vargas. His platoon partner Martin Prado starts again at first base.

Walker is out of the lineup for Monday's game against the Mets, Andre Fernandez of The Athletic reports.

EDGE Analysis

Walker will sit for the third time in five games this season, with all of his benchings coming against left-handed pitching. Though Walker switch hits, he's been far stronger historically against righties (.271/.344/.452 career line, 119 wRC+) than southpaws (.256/.319/.355, 86 wRC+). As a result, he'll likely be included as part of a platoon at first base the entire season.

Walker went 1-for-3 with a walk, run and stolen base in a 3-0 victory against the Rockies on Sunday.

EDGE Analysis

The veteran infielder didn't record a steal in 113 games last season, so it's certainly a surprise to see him post his first one of 2019 so early. Walker now has 30 stolen bases in his career. Owners can chalk up his steal Sunday to veteran savviness, and shouldn't count on it happening regularly in 2019.
