The Astros optioned Kessinger to Triple-A Sugar Land on Monday.

Kessinger was moved off the 26-man active roster in favor of Aledmys Diaz, whose contract was selected ahead of Monday's game against the Athletics. After being called up from Sugar Land on July 2, Kessinger appeared in just four games and went hitless over four at-bats. He had been slashing .283/.356/.387 over 118 plate appearances with Sugar Land prior to his promotion.

The Astros selected Diaz's contract Monday.

Diaz joined the Astros on a minor-league contract July 13 after being released by the Athletics one week prior. He'll be starting up his second stint in the big leagues with Houston, after previously appearing in 262 contests between 2019 and 2022. Before Oakland cut him loose, the 33-year-old utility man logged 30 plate appearances in the big leagues this season, slashing .103/.133/.103 with no extra-base hits.

Perdomo is out of the lineup for Monday's game against the Royals.

After going hitless in the final two games of the Diamondbacks' series against the Cubs this past weekend, Perdomo will get a breather as Arizona's road trip moves to Kansas City. Kevin Newman will step in for Perdomo at shortstop and will bat eighth.

The Mariners optioned Bliss to Triple-A Tacoma on Monday.

Bliss received his first MLB call-up May 27 and picked up 16 starts at second base in June, but playing time has been more difficult to come by in recent weeks. After Jorge Polanco returned from the injured list June 24 and took back everyday duties at the keystone, Bliss started just two of the Mariners' ensuing 21 games and went 0-for-10 with six strikeouts over that stretch. He'll get the opportunity to play on a more frequent basis with Tacoma.

Moore went 1-for-2 with a two-run triple and a walk in a win over the Astros on Sunday. He was also caught stealing on his only attempt.

The slugging veteran came into the day with just a single extra-base hit -- another three-bagger -- in his previous 16 games, but he snapped that rare drought with a second-inning laser that plated Josh Rojas and Luke Raley to give the Mariners an early 2-0 lead. The two RBI were also Moore's first since June 22, and despite Sunday's success, he's still carrying a .212 batting average that has plenty of room for improvement.

Fitzgerald went 1-for-2 with a solo home run and a walk in Sunday's 3-2 win over the Rockies.

Fitzgerald has homered in back-to-back games as he continues to build a case for more playing time. Most importantly, his homer Sunday came off right-hander Ryan Feltner -- Fitzgerald has mostly operated in a short-side platoon role. For the season, the utility man is batting .298 with four homers, seven stolen bases, 10 RBI and 16 runs scored through 92 plate appearances. He continues to be an option primarily in the middle infield whenever Brett Wisely or Thairo Estrada need rest.

Pena went 1-for-4 with a solo home run in Sunday's loss to the Mariners.

Pena connected on a 414-foot blast in the seventh inning off Collin Snider. It was his third home run in July and his eighth for the season, though he's struggled to a .190 batting average in 11 games since July 6. After hitting 22 homers in his rookie season, Pena has combined for just 18 since, but he is still putting together a productive season. The 26-year-old is slashing .274/.318/.387 with 43 RBI, 48 runs and an 18:66 BB:K in 404 plate appearances.

Hamilton went 1-for-4 with two steals in Sunday's loss to the Red Sox.

Hamilton singled his first time up to lead off the second inning and wound up stealing second and third but was left stranded. It was the fifth time this year he stole multiple bases in a game, and Hamilton finds himself in a tie for third in the majors with 25 steals. The 26-year-old has yet to break through as an everyday player for the Red Sox, as he's been finding himself sitting against lefties. Still, Hamilton has shown plenty of improvement after struggling mightily in a brief taste of the majors last year. He's slashing .270/.323/.407 with five homers, 17 RBI, 34 runs and a 15:57 BB:K in 220 plate appearances.

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

Walls will get a breather for Monday's day game after he started each of the first three contests of the series versus the Yankees, going 1-for-7 with a double, three walks, a stolen base and a run. Jose Caballero will step in for Walls at shortstop.

De La Cruz went 1-for-3 with a walk, a double and a stolen base in Sunday's 5-2 loss to Washington.

De La Cruz's sixth-inning double extended his hit streak to nine games. He later stole his 48th base of the season. After a down May (.208 batting average), De La Cruz has been more consistent, posting averages of .266 in June and .276 in July.
