The Rockies selected Hiura's contract from Triple-A Albuquerque on Saturday.

Hiura wasn't able to crack the Rockies' Opening Day roster and started the season in Triple-A, where he is slashing .243/.360/.467 with nine home runs and 31 RBI in 200 plate appearances. With Michael Toglia being optioned to Triple-A, Kyle Farmer will likely take over as the Rockies' everyday first baseman while Hiura provides depth at the position.

The Rockies optioned Toglia to Triple-A Albuquerque on Saturday.

Toglia entered the season tasked with helping anchor the Rockies' lineup. However, the 26-year-old first baseman has slashed .194/.266/.349 with two steals, six home runs, 20 RBI and a league-leading 81 strikeouts in 186 plate appearances. Toglia will go to the minors to regain his form at the plate, with Keston Hiura being promoted to the majors in a corresponding move.

Lowe went 2-for-3 with two walks, two runs scored and two RBI in Friday's win over Arizona.

The first baseman produced his second straight multi-hit game while drawing multiple free passes for the first time since May 7. Lowe has endured a tough May overall, slashing .212/.278/.298 through 115 plate appearances even with the recent mini-surge, but he's still come through with 13 RBI and 14 runs in 26 contests, and he appears to be building some momentum heading into June.

Freeman went 3-for-4 with two doubles, one RBI and one run scored in Friday's 8-5 win over the Yankees.

After going hitless in consecutive games for just the second time all year May 23-24 versus the Mets, Freeman has bounced back in a big way with four multi-hit efforts over his last five contests. He is 10-for-20 (.500) with three RBI and three doubles in that span. The star first baseman is batting .368 with a 1.066 OPS while adding nine home runs, 16 doubles, 37 RBI, 31 runs scored and one triple over 46 contests this season.

Olson went 1-for-4 with an RBI in Friday's 5-1 loss to Boston.

Olson tallied his 15th RBI of the month and his 30th of the season, and he remains a strong source of power despite a subpar batting average. Across 103 at-bats in May, the All-Star first baseman is hitting just .243 but has eight home runs, five doubles and 15 RBI. Olson entered Friday with an elite 18.7 percent barrel rate and 56.0 percent hard-hit rate in 2025, and he's begun to return to form in the slugging department following a slow start to the year in that area.

Harper (elbow) is not in Friday's lineup against the Brewers, Scott Lauber of The Philadelphia Inquirer reports.

Harper will miss a third straight game with a right elbow bruise. Alec Bohm is starting at first base while Edmundo Sosa mans third. Harper called himself "super day-to-day" Friday, but he hasn't tried swinging a bat yet and likely won't Friday, per Paul Casella of MLB.com, so it's possible this turns into an IL stint. When Betts returns, he'll be wearing a new elbow brace, according to Matt Gelb of The Athletic.

The Marlins designated Mervis for assignment Friday.

Mervis' .175/.254/.383 slash line through 134 plate appearances this season was enough for the Marlins to move on after acquiring him from the Cubs during the offseason. The 27-year-old has yet to find much success across parts of three-big league seasons with a .560 OPS, but he could still receive some interest on waivers given his prospect pedigree.

Mervis is expected to be designated for assignment by the Marlins ahead of Friday's series opener against the Giants, Craig Mish of the Miami Herald reports.

Mervis was acquired from the Cubs in December, but his new organization has apparently seen enough after he stumbled to a .175/.254/.383 slash line with seven homers and a 37.3 percent strikeout rate through 42 games this season. The 27-year-old could receive some interest on waivers given his prospect pedigree, but his .165 batting average and .560 OPS through 260 career big-league plate appearances is likely to dissuade most clubs.

Lowe went 2-for-5 with an RBI and a run scored in Thursday's 9-3 win over the Mariners.

It was Lowe's first multi-hit game since May 6, and he has just one extra-base hit over his last nine games. The veteran first baseman is hitting only .211 with two RBI and two runs scored during this period. Even with the power outage -- he has only two long balls in May -- Lowe has managed to log at least one hit in seven of these nine outings.

Harper (elbow) is out of the lineup for the second game of Thursday's doubleheader against Atlanta.

Harper was absent from the first game of Thursday's doubleheader as well, but Phillies manager Rob Thomson said Harper was feeling better after Game 1, Charlotte Varnes of The Athletic reports. Alec Bohm has the start at first base and is batting third while Edmundo Sosa enters the lineup at third base.
