Vargas is not in Saturday's lineup against the Athletics.

Vargas has been getting regular run at third base for the White Sox, but he sits against some right-handed pitchers and Yoan Moncada (adductor) could eventually return to the hot corner. Vargas has just three hits across 22 at-bats with 10 strikeouts across eight games in September. Bryan Ramos will replace Vargas in the lineup Saturday.

Alvarez was optioned to Triple-A Las Vegas on Saturday.

Alvarez had been with the big-league club since Aug. 27, though he had picked up eight at-bats in that span. He'll head back to the minors to make room for Tyler Soderstrom (wrist) to return from the injured list.

Barger will hit seventh and play third base Saturday against the Cardinals.

Barger was not in Toronto's original lineup but was inserted to replace the injured Leo Jimenez (finger). Barger has picked up only 18 at-bats so far in September, collecting three hits with a homer, three RBI and three runs scored.

DeJong isn't in the Royals' lineup Saturday versus Pittsburgh.

DeJong will sit for the second consecutive game after going 3-for-21 with an RBI and eight strikeouts to begin the month of September. Maikel Garcia will step in as Kansas City's third baseman and bat eighth.

Smith started at shortstop and went 2-for-5 with a run scored in Friday's 5-4 loss to the Mariners.

Smith made a sixth consecutive start at shortstop, and the Rangers will now be without Corey Seager (hip, hernia) for the rest of the season. Smith should see the bulk of the time at shortstop to finish off what has been his best year in the majors. He's batting .264/.348/.403 with 12 home runs, 56 RBI, nine steals and 61 runs scored over 136 games.

Westburg (hand) has begun hitting in the cage and is participating in full baseball activities, Jacob Calvin Meyer of The Baltimore Sun reports.

It's another positive step in Westburg's recovery from a fractured hand he suffered in late July. The next step would be a rehab assignment with Double-A Bowie or Triple-A Norfolk. Before landing on the IL, Westburg was slashing .269/.317/.497 with 18 home runs and 58 RBI across 420 plate appearances.

Mayo is not in Friday's lineup against the Tigers.

The righty-hitting Mayo started two of the past three games (all against righties), but he'll head to the bench Friday with righty Beau Brieske working as the opener and lefty Brant Hurter expected to come in as the primary pitcher. Emmanuel Rivera draws the start at third base, batting eighth. Mayo is hitting .133 with a walk and six strikeouts in 15 at-bats since being a September call-up.

Jung is out of the lineup for Friday's game against the Orioles, Evan Woodbery of MLive.com reports.

Jung started the previous four games and will receive a day off after going 2-for-9 with three walks, a double and five runs during that span. Matt Vierling will shift to third base while Wenceel Perez receives a start in right field against Baltimore righty Zach Eflin.

DeJong is out of the lineup for Friday's game against Pittsburgh.

DeJong is out of the lineup for the third time in four games, with Adam Frazier slotting in at third base Friday. Since being dealt to Kansas City, DeJong has slashed .239/.294/.467 across 30 games. However, he's gone just 3-for-19 in September.

Jung went 1-for-4 with a solo home run in Thursday's 5-4 win over Seattle.

Jung launched his seventh homer and first in eight games in the second inning to give Texas an early lead. Since returning from a thumb injury that cost him nearly four months, Jung is slashing .260/.288/.390 with five home runs, nine RBI, three steals and 13 runs scored over 38 games.
