The Nationals optioned Tena to Triple-A Rochester following Sunday's 11-9 loss to the Phillies.

Making a start at second base Sunday, Tena went 1-for-4 with an RBI double and his third stolen base of the season, but the performance wasn't enough for him to maintain his spot on the 26-man active roster heading into the Nationals' three-game series with the Mets, which begins Tuesday. The 24-year-old infielder has handled a limited role across his multiple stints in the big leagues this season, slashing .243/.341/.355 with no home runs, 16 RBI and 19 runs over 169 plate appearances.

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

For the first time since he was called up from Triple-A Albuquerque on Aug. 8, Karros will receive a day off. The 23-year-old has kicked off his big-league career in impressive fashion, slashing .290/.389/.387 with three doubles, a 5:6 BB:K, three RBI and seven runs in nine games. Orlando Arcia will cover third base Sunday in his stead.

Brujan is out of the lineup for Sunday's game against the Guardians.

He made three starts over a five-game stretch prior to the return of Ronald Acuna from the IL, but Brujan has been stuck to the bench since. So long as Atlanta's regular outfield trio of Acuna, Michael Harris and Jurickson Profar remains healthy, Brujan will be in line for sporadic playing time.

Pauley is out of the lineup for Sunday's game against the Red Sox.

Pauley will be joined on the bench by fellow left-handed hitters Troy Johnston, Liam Hicks and Jakob Marsee while the Red Sox send southpaw Garrett Crochet to the hill. Javier Sanoja will replace Pauley at third base and will bat fifth.

The Phillies optioned Kemp to Triple-A Lehigh Valley on Sunday.

The rookie had started just three of the last eight games, and since his playing-time outlook wasn't going to improve with Alec Bohm (rib) returning from the injured list Sunday, the Phillies opted to send Kemp back to the minors. After getting called up from Triple-A on June 7, the 25-year-old slashed .228/.298/.359 with four home runs, one stolen base, 17 RBI and 17 runs over 46 games.

The Phillies reinstated Bohm (rib) from the 10-day injured list, and he will start at third base and bat cleanup Sunday against the Nationals.

The third baseman has been on the shelf nearly a month due to a left rib fracture, but he's ready to rejoin the Phillies after going 3-for-21 over five minor-league rehab games. In 37 games since June 1, Bohm is batting .290 with three home runs, 21 RBI, 14 runs and a .749 OPS.

Hayes went 2-for-4 with a solo home run and a sacrifice fly during Saturday's 6-5 extra-innings loss to the Brewers.

The third baseman ended Quinn Priester's shutout effort by going deep to left field in the sixth inning, and Hayes added another run in the 11th on a sacrifice fly. He's struggled at the plate since being acquired by the Reds from the Pirates in late July, but Hayes has recorded a hit in four of his last six games while going 6-for-17 (.353) over that span.

Marte went 2-for-5 with a solo homer during the Reds' 6-5 extra-innings loss to the Brewers on Saturday.

He made things interesting in the 11th inning by taking the second pitch he saw from Nick Mears deep to left field to reduce the Reds' deficit to one run. Marte has been hot at the plate as of late and is on a seven-game hitting streak, going 13-for-30 (.433) with five doubles, two home runs and nine RBI over that span.

Baty went 2-for-3 with two runs scored and a stolen base in Saturday's 3-1 win over the Mariners.

Baty singled twice and came around to score the Mets' first two runs, adding a stolen base in the seventh inning. The 25-year-old is 9-for-25 through nine August contests with three multi-hit efforts, two home runs, four RBI and seven runs scored in that span. For the season, he's slashing .239/.297/.421 with 13 homers, 38 RBI, 36 runs scored and six steals across 314 plate appearances.

The Rockies activated Arcia (elbow) off the injured list Saturday.

Arcia missed the minimum 10 games while on the IL due to right elbow inflammation. Though he's now healthy enough to return to action, he may be reduced to a part-time role given that Kyle Karros has hit well while manning the hot corner after being promoted in the wake of Arcia's IL stint. Aaron Schunk was sent down to Triple-A Albuquerque on Saturday to clear room for Arcia's return to the 26-man roster.
