Semien will start at second base and bat ninth in Friday's game versus the White Sox.

Semien was demoted from leadoff to the fifth spot in the lineup in late April, and he's now been dropped all the way to the bottom of the batting order. The veteran infielder has just a .512 OPS in May after posting a .504 OPS in April.

The Athletics transferred Gelof (wrist/ribs) to the 60-day injured list Friday, Martin Gallegos of MLB.com reports.

Gelof will vacate his spot on the 40-man roster in a purely transactional move, as the second baseman has been sidelined since March 26. Gelof had been recovering from surgery on his right wrist but got pulled from his rehab assignment May 5 after being diagnosed with a stress reaction in his ribs. The 25-year-old remains without a timetable for return.

Torres (lower leg) will DH and bat second in Friday's game against the Guardians.

Torres left Thursday's game against Cleveland after the third inning due to discomfort in his lower right leg. However, the injury wasn't severe enough to keep him out of Friday's starting nine. Torres has one hit in his last 12 at-bats.

The Royals recalled Loftin from Triple-A Omaha on Friday.

The 26-year-old is taking the roster spot vacated by Hunter Renfroe, who has been designated for assignment. Loftin sports a .295/.451/.468 slash line with four home runs, 12 steals and a 22:39 K:BB over 40 Triple-A games. He's primarily been used at third base by Omaha this year but has also seen action at first base, second base and left field, and he could find opportunities around the diamond on a Royals club that's starved for offense.

Moore went 2-for-4 with a solo home run in Thursday's 9-2 loss to the Astros.

This was Moore's first multi-hit effort since May 7, his second game back from a mild hip injury. Over the previous 11 contests, he went just 6-for-29 (.207) with a home run, four RBI and a 4:15 BB:K. The utility player still gets in the lineup a majority of the time, but his recent struggles at the plate could see his role reduced slightly until he turns things around. Moore has a .279/.339/.514 slash line with eight homers, 16 RBI, 20 runs scored, eight stolen bases and two doubles across 124 plate appearances. While the hitting has been decent overall, he's had some struggles defensively -- his five errors this season already match his totals from each of the previous two years.

Torres exited Thursday's game against the Guardians due to lower right leg discomfort, Evan Petzold of the Detroit Free Press reports.

Torres was pulled after hitting a hard line drive to end the third inning. It's unclear how serious the issue is, or if Torres will be forced to miss additional time.

Torres was removed from Thursday's game against the Guardians in the fourth inning, Evan Petzold of the Detroit Free Press reports.

There was no injury announced and no clear issue before Torres exited the contest, so this will be a situation to monitor as more details emerge. Andy Ibanez entered the game at second base to take his place.

Vivas went 1-for-1 with a solo home run in two plate appearances during Thursday's 1-0 win over the Rangers.

Vivas picked a good time for his first home run of the season, scoring the only run of the game off of Rangers starter Nathan Eovaldi. Vivas also reached base on catcher's interference as part of a perfect day at the plate before being replaced by DJ LeMahieu in the seventh inning. The 24-year-old Vivas will look to use this game to get going offensively, as he is hitting just .182 through 36 plate appearances for the season.

Arias isn't in the lineup for Thursday's game against Detroit.

Arias will get a chance to clear his head Thursday after going just 4-for-33 with 12 strikeouts across his last 10 games. Daniel Schneemann will start at shortstop and bat sixth while Arias rests.

Urias is out of the lineup for Thursday's game against the Angels.

Max Schuemann will get the nod at the keystone Thursday, but Urias had manned second base in each of the last six games and still appears to be the Athletics' preferred option at the position while Zack Gelof (wrist/rib) remains on the injured list. Since moving into an everyday role in late April, Urias has slashed .272/.358/.457 with five home runs and one stolen base in 28 games.
