Duran entered Sunday's game in the seventh inning after first baseman Jake Burger was removed with a wrist injury. Duran finished out the game at first base and went 0-for-1 with a walk in a 10-4 victory over the Blue Jays.

There's no shortage of players on the roster that can play first base, and Duran could be the choice against lefties should Burger miss any time. Against right-handers, manager Bruce Bochy has Josh Smith, Rowdy Tellez and Joc Pederson that hit from the left side of the plate.

Brito (hamstring) is running, fielding and hitting following a significant left hamstring strain sustained in early July, MLB.com reports.

It's been six weeks since Brito landed on the injured list, and the estimated recovery time for strains like his is between eight and 12 weeks. That gives him a chance to return to action at some point in September. The hamstring and an earlier thumb injury put a damper on an important year of development for Brito, who has played 24 games at Triple-A Columbus and another seven in the rookie-level Arizona Complex League.

Seager went 2-for-5 with a solo homer and an additional run scored during Sunday's 10-4 win over the Blue Jays.

Seager entered Sunday's contest having gone 0-for-15 with one steal over his last four games. He broke out of his slump with a solo homer in the fifth before being brought home in the ninth on a two-run blast from Evan Carter. Seager has a .778 OPS with two steals, five homers and 14 RBI in 119 plate appearances since the All-Star break.

De Vries was promoted to Double-A Midland on Sunday, Francys Romero of BeisbolFR.com reports.

De Vries will move up a level in the Athletics' minor-league system after combining to bat .249 with 10 home runs, 58 RBI, 55 runs scored and nine stolen bases over 366 at-bats between High-A Fort Wayne and High-A Lansing this season. The 18-year-old is considered to be the team's top overall prospect, and he'll now get the chance to dip his toe into the Double-A level before the conclusion of the 2025 campaign.

Volpe is out of the lineup for Sunday's game in St. Louis.

The day off ends a run of 46 consecutive starts for Volpe, who has gone 3-for-26 (.115 average) with a double and a homer in the past seven games. Jose Caballero will step in at shortstop and bat ninth for the series finale against the Cardinals.

Arias is out of the lineup for Sunday's game against Atlanta.

Arias will get a breather after starting 16 straight contests and slashing .214/.258/.375 with two home runs, two stolen bases, 13 RBI and five runs. Brayan Rocchio will slide over from his usual spot at second base to cover shortstop.

Pena (illness) is starting at shortstop and batting leadoff Sunday against the Orioles, Brian McTaggart of MLB.com reports.

Pena sat out the previous two contests due to an illness but is good to go for Sunday's series finale. The 27-year-old has a .283/.340/.500 slash line with two homers and two steals through 12 games in August.

Duran started at second base and went 1-for-4 with a double in Saturday's 14-2 loss to Toronto.

Duran stepped in at second base for the injured Marcus Semien (wrist), who was hit by a pitch Friday and held out Saturday. X-rays on Semien's wrist came back negative, and he'll be re-evaluated ahead of Sunday's series finale. While Duran can play multiple positions, second base is not high on his list of appearances. He's played 22 games there during his career, and only twice this season.

Rocchio went 2-for-3 with a solo home run in Saturday's 10-1 loss to Atlanta.

Rocchio swatted his second home run of the season in the third inning, when the game was still close. He's hit safely in seven of the last eight contests, going 8-for-27 (.296) with a double, a homer, two steals and four RBI during that stretch. Following a shaky start to the season that resulted in him being sent back down to the minors, Rocchio has hit well since his return. He's produced a .760 OPS over 40 contests since early July and settled in as team's primary second baseman.

Hernaiz went 2-for-3 with two RBI and a run scored in Saturday's 7-2 victory over the Angels.

Hernaiz played a role in Saturday's win, delivering a two-out, two-run single with the bases loaded off Tyler Anderson in the third inning. The infielder has seen fairly consistent playing time since Jacob Wilson went down with a forearm injury and has made the most of it, posting a .758 OPS through 16 games at the big-league level this season.
