Aranda is out of the lineup for Monday's game against the Phillies, Marc Topkin of the Tampa Bay Times reports.

The lefty-hitting Aranda had started in each of the Rays' last three games -- all against right-handed pitching -- going 2-for-11 with a double, a walk and two runs. He'll be on the bench Monday against a lefty (Cristopher Sanchez), but Aranda's opportunities to play against right-handed pitching could take a hit as soon as Brandon Lowe (finger) is able to return to the lineup. Lowe is on the bench Monday for a fourth straight game and remains day-to-day.

Manager Brandon Hyde relayed Monday that he wasn't sure when Mountcastle (wrist) would return from the 10-day injured list, Jake Rill of MLB.com reports.

Mountcastle sprained his left wrist Aug. 22 against Houston while sliding into second base. He was placed on the 10-day injured list four days later, but it wasn't until Friday that he started swinging a bat by hitting off a tee. The Orioles are in a tight race in the AL East with the Yankees, but they have a comfortable lead in the AL Wild Card, so there could be caution in bringing Mountcastle back into the fold to avoid aggravating his wrist injury. From the end of the All-Star break to his placement on the IL, Mountcastle had a slash line of .259/.296/.370 with one home run and 18 RBI across 115 plate appearances.

Casas is not in the lineup for Monday's contest versus the Orioles, Gabrielle Starr of the Boston Herald reports.

The left-handed-hitting Casas will grab a seat as the Orioles send southpaw Cade Povich to the bump. Connor Wong will draw the start at first base for the Red Sox in the series opener.

Soderstrom (wrist) took a full game's worth of plate appearances as the designated hitter in Triple-A Las Vegas' loss to Round Rock on Sunday, going 2-for-3 with a two-run home run, an RBI single and two walks.

Not only was Soderstrom able to play in back-to-back games for the first time during his rehab assignment, but he more than demonstrated his previously injured wrist was up to the task with his productive evening with the bat. Soderstrom seems to quickly be working off any rust from his near two-month layoff, as he's hitting .333 with Sunday's round tripper and five total RBI over his first three rehab games.

Turner went 2-for-3 with a double, a walk and two runs in a win over the Cardinals on Sunday.

Turner was a late lineup replacement for Victor Robles (elbow) and made good use of his inclusion into the starting nine, pushing his season OBP to a stellar .344 with his trio of trips on the basepaths. The 39-year-old is showing he still has plenty of life in his bat, now having authored three multi-hit efforts in his last eight games and furnishing a .321 average and 1.031 OPS across 33 plate appearances in that stretch.

Lowe went 2-for-3 with a two-run home run and a hit-by-pitch in Sunday's 7-4 win over the Angels.

Lowe's first-inning long ball was just his third over 34 games since the start of August. He's batting .246 (29-for-118) in that span, which is a bit worse than his .263 average for the season. The first baseman has added a decent .745 OPS, 12 homers, 53 RBI, 54 runs scored and two stolen bases over 122 contests.

Singleton is out of the lineup for Sunday's game against the Diamondbacks.

Singleton had started at first base in both of the Astros' previous two matchups with right-handed pitchers, but he'll give way to Victor Caratini while righty Ryne Nelson takes the hill for Arizona in the series finale. With an OPS of .694 since the All-Star break, Singleton hasn't done enough to fully solidify a strong-side platoon role, though he's still likely to see the majority of the starts at first base down the stretch.

Kavadas is out of the lineup for Sunday's game against the Rangers.

The lefty-hitting Kavadas had started at designated hitter in each of the Angels' last four matchups against righties, but he'll take a seat Sunday versus Rangers southpaw Andrew Heaney. Brandon Drury will get a day out of the infield and will replace Kavadas as the club's DH.

Schanuel is out of the lineup for Sunday's game against the Rangers, Erica Weston of Bally Sports West reports.

Schanuel started the previous 11 games after missing a couple contests due to a back issue, and he'll receive Sunday off after going 5-for-40 since rejoining the lineup. Charles Leblanc will take over at first base and bat third in the series finale at Texas.

Turner is starting at first base and batting fifth Sunday against the Cardinals.

The 39-year-old was poised to sit Sunday in St. Louis but will instead start the contest since Victor Robles (elbow) was scratched. Turner is off to a slow start in September, as he's gone 4-for-20 with four walks, a double, an RBI and two runs in six games.
