Locklear is not in the lineup for Tuesday's game against the Guardians.

EDGE Analysis

Locklear has now been on the bench for two straight games versus right-handers since Pavin Smith returned from the injured list. While the 24-year-old should operate as more than a short-side platoon bat, it's clear that Smith will put a significant dent in Locklear's playing time.

Locklear is not in the lineup for Monday's game against the Guardians.

EDGE Analysis

Pavin Smith is starting at first base in his first game back from the injured list. Locklear had started each of the previous 16 contests and should still function as the team's primary first baseman down the stretch, but Smith could eat into his playing time somewhat.

Locklear went 2-for-5 with a solo home run in Monday's 7-6 extra-inning loss to the Rangers.

EDGE Analysis

Locklear gave the Diamondbacks an early lead with his second home run since being traded to Arizona. He's operated as the primary first baseman after Josh Naylor was traded and Pavin Smith (oblique) landed on the 10-day injured list. Smith begins a rehab assignment Tuesday and could return for a homestand beginning next Monday. A lefty-righty platoon between Smith and Locklear is a possibility, but the organization may opt to give the younger Locklear the at-bats as Arizona plays out the string. Locklear has a .653 OPS with a 34.9 strikeout percentage over 43 plate appearances.

Locklear went 1-for-4 with a solo home run in Monday's 6-2 win over the Padres.

EDGE Analysis

Locklear has started four straight games at first base for Arizona since he was acquired from Seattle in the Eugenio Suarez deal last week. The Diamondbacks' sell-off at the deadline suggests a pivot toward evaluating for 2026, and getting a prospect like Locklear some significant playing time is a factor in that. In addition to his homer, he's added a stolen base and a 2:5 BB:K in his time with Arizona so far. He may face a challenge for playing time once Pavin Smith (oblique) returns from the injured list.

The Diamondbacks plan to deploy Locklear as their primary starting first baseman after acquiring him in a trade with the Mariners on Wednesday, John Gambadoro of Arizona Sports 98.7 FM reports.

EDGE Analysis

Pavin Smith (oblique) should return from the 10-day injured list sometime in August, but he could remain mostly at designated hitter while Locklear receives an opportunity to become the Diamondbacks' long-term answer at first base. Locklear struggled during his cup of coffee in the majors last season but has slashed .316/.401/.542 with 19 home runs and 17 stolen bases in 434 plate appearances at Triple-A Tacoma this season.

The Mariners traded Locklear to the Diamondbacks on Wednesday alongside Hunter Cranton and Juan Burgos in exchange for Eugenio Suarez, Daniel Kramer of MLB.com reports.

EDGE Analysis

The Mariners recalled Locklear from Triple-A on Wednesday, but instead of backing up Josh Naylor, the 24-year-old will now aim to carve out a role for himself in Arizona. Locklear has impressed in the minors this year, slashing .316/.401/.542 with 19 home runs, 82 RBI, 70 runs scored and 17 stolen bases through 434 plate appearances in Triple-A. He should fill in as the D-backs' first baseman for the immediate future, though his path to playing time will become less clear once Pavin Smith (oblique) is activated from the injured list.

The Mariners recalled Locklear from Triple-A Tacoma on Wednesday.

EDGE Analysis

Locklear has been mashing this season with Tacoma, sporting a .316/.401/.543 batting line with 19 home runs and 17 stolen bases over 97 games. With Josh Naylor manning first base, Locklear's best chance at playing time would be if the Mariners open up the designated-hitter spot by shifting Jorge Polanco to second base on a permanent basis. The right-handed-hitting Locklear could also occupy the short side of a platoon with the left-handed-hitting Naylor, who has produced a 94 wRC+ versus southpaws on the season.

The Mariners are expected to recall Locklear from Triple-A Tacoma on Wednesday, Adam Jude of The Seattle Times reports.

EDGE Analysis

Locklear wasn't able to crack the big-league roster out of spring training, but he's slashed .316/.401/.543 with 19 homers, 81 RBI, 70 runs scored and 17 stolen bases over 97 games in Triple-A. The 24-year-old isn't likely to start often in Seattle now that Josh Naylor is a Mariner, though the two players may form a platoon at first base, which would see the right-handed-hitting Locklear start primarily against southpaws.

Locklear is slashing .282/.372/.427 with six home runs, 17 doubles, one triple, 38 RBI, 34 runs scored and 12 stolen bases over 68 games covering 293 plate appearances with Triple-A Tacoma this season.

EDGE Analysis

The 24-year-old first baseman is showcasing an intriguing blend of power and speed at first base in the minor leagues. Locklear ranks as Seattle's No. 11 prospect for 2025, per MLB Pipeline, and he remains an option for a Mariners club that has gotten fairly lackluster production overall across their platoon at the cold corner. The lefty-hitting Rowdy Tellez has a .720 OPS against righties this season, and the righty-hitting Donovan Solano has a .413 OPS versus southpaws for the year.

The Mariners optioned Locklear to Triple-A Tacoma on Saturday.

EDGE Analysis

Locklear will end up missing the cut for Seattle's Opening Day roster after going 4-for-18 with three RBI and three runs scored over 11 games in the Cactus League. The 24-year-old owns just a .535 career OPS in the majors through 49 plate appearances and will likely need to bounce back offensively in Triple-A before the Mariners consider bringing him back to the big leagues.
