Johnston made the Rockies' Opening Day roster, Kevin Henry of The Denver Gazette reports.

EDGE Analysis

Johnston was claimed off waivers by the Rockies in November, and he earned a place on the Opening Day roster with a .973 OPS across 22 spring training games. The 28-year-old is expected to begin the season in a reserve role, but he could get an opportunity for regular playing time at some point given Colorado's lack of established pieces.

The Rockies claimed Johnston off waivers from the Marlins on Wednesday.

EDGE Analysis

Johnston reached the majors for the first time in 2025 as a 28-year-old and fared well, slashing .277/.331/.420 with four home runs over 121 plate appearances. He can play first base and the corner outfield spots and could see ample playing time on a talent-deficient Rockies roster.

Johnston went 2-for-4 with a home run and an additional RBI in Saturday's 4-3 win over Texas.

EDGE Analysis

Johnston blasted his fourth homer of the season, also logging multiple hits for the fourth time this month. The rookie outfielder has made a nice impression since being called up in late July, as he's settled in as Miami's primary right fielder. Through his first 99 at-bats, Johnston is batting .283 with four long balls, 13 RBI, 10 runs scored and two stolen bases.

Johnston went 2-for-4 with a walk, two home runs and three RBI in Saturday's 6-4 extra-innings win over the Tigers.

EDGE Analysis

After taking Troy Melton deep for a solo shot in the sixth inning, Johnston walked it off in the 11th with a two-run homer off Rafael Montero. The 28-year-old rookie came into the game with just one long ball in his first 32 big-league contests, and the performance may have snapped a September swoon for Johnston in which he'd gone just 2-for-21 (.095) with zero RBI over his prior nine games.

Johnston is out of the lineup for Monday's game against the Nationals.

EDGE Analysis

The Nationals are sending lefty Andrew Alvarez to the hill for the series opener, so Johnston will head to the bench along with another lefty-hitting lineup regular in Liam Hicks. Johnston closed August with a .293/.328/.414 slash line, one home run, one stolen base, seven RBI and five runs over 23 games.

Johnston went 3-for-5 with a triple, two runs scored and an RBI in Friday's loss to the Mets.

EDGE Analysis

Starting in left field and batting seventh, Johnston delivered his fourth multi-hit performance in the last nine games, a stretch in which he's batting .480 (12-for-25) with three runs and four RBI. The 28-year-old has emerged as the Marlins' preferred option in left field against right-handed pitching while still occasionally spotting in at first base or right field, a role he could fill until Kyle Stowers (oblique) gets healthy.

Johnston is out of the lineup for Wednesday's game against Atlanta.

EDGE Analysis

With a lefty (Joey Wentz) on the hill for Atlanta, the left-handed-hitting Johnston will head to the bench for the series finale. Johnston had started in each of Miami's last seven games at first base or in left or right field, going 8-for-20 with one double, two walks and three RBI during that stretch.

Johnston is out of the lineup for Sunday's game against the Red Sox.

EDGE Analysis

Johnston was in the lineup for three of the past four games against right-handed pitchers, but he'll take a seat Sunday while southpaw Garrett Crochet takes the bump for Boston. Johnston is slashing .214/.241/.357 with one home run and one stolen base over 29 plate appearances since getting called up from Triple-A Jacksonville on July 29.

Johnston is out of the lineup for Sunday's game against Atlanta.

EDGE Analysis

The 28-year-old rookie was on the bench for the second game of Saturday's doubleheader while Atlanta sent righty Erick Fedde to the hill, and Johnston will remain there with southpaw Joey Wentz on the mound for the series finale. Since getting the call to the big leagues July 29, Johnston has gone just 4-for-21 with no walks and six strikeouts. He's in danger of losing playing time if he's unable to get going at the plate soon.

Johnston isn't in the lineup for the second game of Saturday's doubleheader against Atlanta.

EDGE Analysis

Johnston will get a chance to catch his breath after going 1-for-3 with a strikeout during a loss in Game 1. While he rests, Eric Wagaman will get the nod at first base, and Jakob Marsee, Derek Hill and Heriberto Hernandez will work in the outfield.
