O'Hearn was traded from the Orioles to the Padres on Thursday along with Ramon Laureano, Robert Murray of FanSided.com reports. The Orioles received Boston Bateman, Brandon Butterworth, Victor Figueroa, Cobb Hightower, Tyson Neighbors and Tanner Smith in return.

Several teams were in on O'Hearn, but the Padres went big to acquire both him and Laureano. O'Hearn typically sits against lefties, but he is slashing .294/.384/.490 with 13 home runs in 255 at-bats against righties this season.

Mountcastle (hamstring) has gone 8-for-19 (.421) with two home runs, three doubles and six RBI over five games during his rehab assignment with Triple-A Norfolk.

After spending two months on the shelf due to a right hamstring strain, Mountcastle appears to be on the verge of being activated from the injured list. The 28-year-old slugger is expected to spend the weekend in the minor leagues to wrap up his assignment, and the Orioles are likely to reinstate him ahead of Monday's series opener in Philadelphia if all goes well. Mountcastle should return to his role as Baltimore's primary first baseman upon his return, which would shift Ryan O'Hearn back into the outfield, and it remains to be seen how much playing time Coby Mayo will see down the stretch. That outlook could change depending on what the Orioles do ahead of Thursday's trade deadline, however.

Aranda was lifted from Thursday's game against the Yankees in the fifth inning with an apparent left wrist injury, Marc Topkin of the Tampa Bay Times reports.

He was playing first base when a throw from Junior Caminero took Aranda up the line. Aranda's hand collided with the midsection of Giancarlo Stanton -- who was trying to beat out an infield single -- and Aranda immediately fell to the ground in pain. He is likely to undergo tests, and the Rays could have more on his status after the game. Aranda went 1-for-2 with an RBI single in his two plate appearances before exiting.

The White Sox reinstated Noda (quadriceps) from the injured list Thursday and optioned him to Triple-A Charlotte.

Noda had been on the shelf since July 7 with a right quad strain, though he had been on a rehab assignment with Charlotte for the past week. During his assignment, the 29-year-old went 2-for-19 with a home run, two RBI, four runs scored and eight strikeouts. He'll stay put in Triple-A now that he's fully healthy, and the White Sox will move forward with Miguel Vargas as their main first baseman.

Freeman went 1-for-2 with a two-run home run and two walks Wednesday in a loss to Cincinnati.

Prior to Wednesday, Freeman had gone 23 games without a homer. He snapped that drought in the fourth inning against Reds hurler Nick Martinez, bashing a two-run shot to account for Los Angeles' only runs of the game. Freeman has reached base safely in eight of his past nine contests and is slashing .343/.425/.457 with seven RBI during that span.

Smith went 2-for-4 with an RBI in Wednesday's 2-1 extra-inning loss to the Pirates.

Smith tallied two of the Giants' six hits and delivered an RBI single in the fourth inning. The first baseman has seen a slight dip in playing time since the All-Star break, logging a plate appearance in five of San Francisco's 12 games in that stretch. During that span, he's slashing .412/.500/.471 with two RBI, two runs scored and a double across 20 plate appearances.

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.

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.

Schanuel went 1-for-4 with a two-run home run Wednesday in a loss to the Rangers.

Schanuel brought the Angels to within three runs with his two-run blast in the eighth inning, but those were the final runs either team would score. The first baseman isn't known for his power, and Wednesday's long ball was his first over his past 22 contests. Schanuel is at nine home runs on the season after going deep 13 times across 147 games in his first full MLB campaign last year.

Arizona acquired Locklear and right-handers Hunter Cranton and Juan Burgos from Seattle on Wednesday in exchange for third baseman Eugenio Suarez, Daniel Kramer of MLB.com reports.

The Mariners recalled Locklear from Triple-A Tacoma on Wednesday, but instead of backing up Josh Naylor at first base, the 24-year-old will now aim to carve out a role for himself in Arizona. Locklear has impressed in the minors this season, slashing .316/.401/.542 with 19 home runs, 82 RBI, 70 runs scored and 17 stolen bases through 434 plate appearances at Triple-A. He should step in as Arizona's primary 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 Rays acquired Feduccia on Wednesday in a three-team trade with the Reds and Dodgers, Jeff Passan of ESPN.com reports.

Feduccia has performed well in Triple-A this season with a .287/.398/.460 slash line through 329 plate appearances, but he was unlikely to spend a lot of time in the majors with Will Smith and Dalton Rushing already on the Dodgers. The path to playing time is much more favorable in Tampa Bay, as the Rays' catcher room currently consists of Nick Fortes (.632 OPS) and Matt Thaiss (.638 OPS).
