After an underwhelming spring training, Keith may end up splitting time at third base with several other players, Jason Beck of MLB.com reports.

Keith sported a .662 OPS and no home runs across 17 Grapefruit League games. His middling results, along with a deep Detroit roster that features Zach McKinstry and Matt Vierling as primary options at the hot corner, could force Keith into something of a timeshare. Top prospect Kevin McGonigle is on the roster as well and is expected to see most of his time at shortstop, though he could also slide over to third on days when Javier Baez plays up the middle. Either way, Keith will likely need to produce at the plate if he wants to hold onto regular playing time.

The Padres placed Song (oblique) on the 10-day injured list Wednesday.

Song remains on the mend from the right oblique strain that he aggravated in March. He'll open the season on the IL and can make his MLB debut as soon as April 1, but MLB.com relays that he's trending toward a mid-April return. Song was able to play in a minor-league game on the back fields of camp this past Sunday, so he could be ready to begin a rehab assignment at Triple-A El Paso when the season gets underway this weekend.

The Mariners placed Mastrobuoni (calf) on the 10-day injured list Wednesday.

Mastrobuoni strained his right calf while playing for Team Italy in the World Baseball Classic two weeks ago. He'll be eligible to return April 1, but the utility player figures to require a bit more down time than that.

The Rockies placed Freeman (back) on the 10-day injured list Wednesday.

Freeman is without a definitive timeline to return from the IL, though manager Warren Schaeffer doesn't believe the 26-year-old will require an extended stay on the shelf, per MLB.com. Once he's activated, Freeman is likely to serve as a super-utility player for Colorado.

The Rockies selected Rumfield's contract from Triple-A Albuquerque on Wednesday.

Manager Warren Schaeffer announced Sunday that Rumfield made Colorado's Opening Day roster, and the first baseman has now officially been added to the big-league club. The 25-year-old is now on the cusp of his MLB debut and is expected to see regular action at first base after posting a .913 OPS with five homers in 23 spring training games. He spent last season at the Triple-A level with the Yankees, where he had a .285/.378/.447 slash line in 138 contests.

The White Sox designated Mead for assignment Wednesday.

Mead is a victim of the White Sox needing to clear space on their 40-man roster. The former top prospect has yet to establish himself at the big-league level, slashing .238/.300/.317 across parts of three seasons. Mead is still just 25, so there could be a club willing to take a shot at him via waivers.

The Diamondbacks placed Locklear (elbow) on the 10-day injured list Wednesday.

Locklear was held out for the entirety of spring training while recovering from Oct. 16 surgeries to repair the labrum in his left shoulder and a torn ligament in his left elbow. He's not expected to be ready to return from IL until around mid-May to early June.

The Diamondbacks selected Vargas' contract from Triple-A Reno on Wednesday.

Vargas was able to win a spot on Diamondbacks' Opening Day roster as a utility man, beating out Jacob Amaya for one of the final spots on the Arizona bench. After slashing .270/.292/.383 with three home runs and 19 RBI over 121 plate appearances with Arizona in 2025, Vargas will likely be in store for limited playing time this season so long as Ketel Marte (lower leg), Geraldo Perdomo and Nolan Arenado are all healthy.

The Rays placed Walls on the 10-day injured list Tuesday with a right oblique strain.

Walls is slated to miss at least the first couple weeks of the season due to an oblique strain that first popped up in late February. Carson Williams will handle shortstop for the Rays while Walls is out and could keep the job if he gets off to a hot start.

The Angels selected Candelario's contract from Triple-A Salt Lake on Tuesday.

Candelario earned a spot on the Angels' Opening Day roster after slashing .245/.339/.612 with four homers, 10 RBI and eight runs scored over 56 plate appearances in the Cactus League. He will provide infield depth for the big club to begin the season while Vaughn Grissom (wrist) is on the injured list.
