The White Sox optioned Sosa to Triple-A Charlotte on Wednesday, Daryl Van Schouwen of the Chicago Sun-Times reports.

Sosa had a stretch recently with five straight multi-hit games, but he finished the first half going just 2-for-22 across his last six contests and has managed just a .624 OPS on the season. Nick Senzel will take Sosa's spot on the roster and could also replace him as the White Sox's everyday third baseman.

The White Sox designated Mendick for assignment Wednesday.

Mendick will give up his spot on the 40-man roster and 26-man active roster to third baseman Nick Senzel, whom the White Sox signed to a one-year contract Wednesday. While operating largely as a short-side platoon player in the infield for the White Sox this season, Mendick slashed .197/.243/.318 with three home runs and six stolen bases over 141 plate appearances.

Senzel agreed to a one-year, major-league contract with the White Sox on Tuesday, Jon Heyman of the New York Post reports.

Senzel spent most of the first half of the campaign with Washington, slashing .209/.303/.359 with seven home runs, 18 RBI, 25 runs and one stolen base before he was designated for assignment July 6 and later released. He played exclusively at third base with the Nationals but had previously spent the majority of his big-league time in the outfield.

Toro (hamstring) started at third base and played seven innings in the ACL Athletics' loss to the ACL Rangers on Monday, going 1-for-3.

It was a successful start to Toro's rehab assignment given he was able to play almost a full game on defense. The veteran is due to log several games in the minors before activation is considered, so a return immediately at the start of the second half of the season Friday may not be realistic.

The Athletics sent Toro (hamstring) to the rookie-level Arizona Complex League on Monday to begin a rehab assignment.

Toro has been sidelined for nearly a month with a right hamstring strain but is finally ready for game action. He shouldn't require more than a few rehab games before returning to the Athletics' active roster. Prior to getting hurt, Toro was serving as Oakland's everyday third baseman and leadoff hitter.

Jung (wrist) said he took 15 swings with a regular bat off a tee Sunday, MLB.com reports.

According to Shawn McFarland of The Dallas Morning News, Jung admitted that he's not certain of his next step, but the 26-year-old plans to continue swinging the bat over the All-Star break this week. If Jung incurs no setbacks with his surgically repaired right wrist while doing so, the Rangers could then map out a minor-league rehab assignment coming out of the break. Jung previously appeared in four rehab games in June and looked to be on the cusp of returning from the 60-day injured list before experiencing inflammation in his wrist and having his activation date pushed back.

Smith went 2-for-4 with two two-run home runs during Sunday's 4-2 win over the Astros.

As a team, the Rangers logged only three hits Sunday. Two of those came off Smith's bat, and each wound up in the stands for the 26-year-old's first career multi-homer game. During his last 11 games, Smith is batting 13-for-40 (.325) with three homers, seven runs scored, eight RBI and a stolen base.

Yankees manager Aaron Boone said Thursday that Berti (calf) has been running at approximately 95 percent as well as hitting and throwing, MLB.com reports.

Berti is approaching a minor-league rehab assignment, which could begin shortly after the All-Star break. He's been on the injured list since May 25 as a result of a left calf strain. Berti will likely work as a utility man in a reserve role upon his return from the IL.

Rendon is out of the lineup for Sunday's game against the Mariners.

For the first time since he returned Monday following a 68-game stay on the injured list due to a strained hamstring, Rendon will hit the bench. Rendon served as the Angels' leadoff man each of the last six games while making three starts apiece at designated hitter and third base, going 4-for-23 with two doubles, three walks, two runs and one RBI.

The Twins placed Miranda on the 10-day injured list Sunday with a low back strain.

Miranda hadn't played since Wednesday due to the injury and will hit the shelf in advance of the Twins' final game before the All-Star break Sunday in San Francisco. Because the transaction is retroactive to Thursday, Miranda will be eligible to come off the IL as soon as next Sunday, when the Twins will play their second game coming out of the break. Until Miranda is back in the mix, the Twins should have a regular spot in the lineup against right-handed pitching available for Matt Wallner.
