Maldonado is not in the lineup for Tuesday's game against the Diamondbacks.

Maldonado will get some rest after appearing in the last five games since the second game of a doubleheader July 2. In that five-game stretch, he went 2-for-11 with a walk. For Tuesday's game, Elias Diaz has the start behind the dish and is batting ninth.

The Nationals placed Ruiz on the 7-day concussion injured list Tuesday, Mark Zuckerman of MASNSports.com reports.

Ruiz originally landed on the concussion IL on June 27 after being hit by a foul ball while in the dugout. He was activated Friday, but renewed symptoms will force him to remain on the injured list through the All-Star break. Riley Adams will take over as the Nationals' backstop for now, and Drew Millas will come up from Triple-A Rochester to provide some depth behind the plate.

Smith is not in the lineup for Tuesday's contest in Milwaukee.

Smith just had a day off Sunday, but he will get another breather for the second game of the Dodgers' series against the Brewers. Dalton Rushing will get the nod at catcher.

Rutschman (oblique) took dry swings Tuesday, Andy Kostka of TheBaltimoreBanner.com reports.

The swings were low intensity and he didn't hit a ball, but it's still a step forward for Rutschman. The Orioles will wait to see how he recovers before determining the next step in his rehab. Rutschman has already been ruled out through the All-Star break and, given where he's at in his rehab, it seems unlikely he'll be ready for the first game of the second half.

Orioles interim manager Tony Mansolino said Monday that Sanchez (knee) is likely to be sidelined 8-to-10 weeks, Roch Kubatko of MASNSports.com reports.

Sanchez was diagnosed with a moderate PCL sprain in his right knee over the weekend and will be shelved for at least a couple months. The Orioles are also without Adley Rutschman (oblique), Maverick Handley (concussion) and Chadwick Tromp (back), leaving them with Jacob Stallings and Alex Jackson at catcher.

Diamondbacks manager Torey Lovullo said prior to Monday's 6-3 win over the Padres that he would continue to have McCann catch for right-hander Zac Gallen if the battery continues to achieve positive results, Alex Weiner of ArizonaSports.com reports.

Given that Gallen allowed one unearned run on five hits and one walk while striking out nine over six innings Monday, McCann looks like a good bet to remain in the lineup in Gallen's next turn through the rotation. Prior to the Diamondbacks signing McCann on June 23, Gallen endured a nine-start stretch during which he posted a 6.97 ERA and 1.59 WHIP with 21 walks through 51.2 innings. In the two subsequent outings with McCann behind the dish, the right-hander has gone 2-0 with a 0.69 ERA, a 0.85 WHIP, 19 strikeouts and one walk over 13 innings. The catcher has also produced at the plate, going 6-for-18 with two doubles, one home run, three RBI and five runs over six starts behind the dish.

D'Arnaud went 2-for-4 with a home run, a double, two total runs and three total RBI in a 6-5 win against the Rangers on Monday.

D'Arnaud gave the Angels their first lead with a two-run blast in the second inning. The Rangers retook the lead by the end of the third, but d'Arnaud came through again in the sixth, tying the score with a run-scoring double. The veteran backstop remains the clear backup to Logan O'Hoppe, and this was his first start in the team's past five games. D'Arnaud has just a .662 OPS on the season but has offered a bit of pop with five home runs over 142 plate appearances.

Perez went 2-for-4 with a solo homer and an RBI double during Monday's 9-3 win over the Pirates.

Perez homered for a second consecutive night, tagging Chase Shugart for a solo shot in the fifth inning. The veteran catcher has been crushing the baseball in July, going 9-for-28 (.321) with four doubles and a pair of long balls across seven games. Perez is slashing .238/.290/.406 on the year.

Del Castillo (back) is 5-for-17 with three walks and two runs scored in four games with Triple-A Reno since being activated from the 7-day injured list Tuesday.

Del Castillo landed on the 7-day injured list June 20 due to lower back discomfort but was only shut down for one week before gaining clearance to embark on a rehab assignment. He's batting .294 with two home runs, eight RBI and 10 runs through nine appearances this season for the Aces.

Millas is expected to be called up from Triple-A Rochester on Tuesday, Andrew Golden of The Washington Post reports.

Millas is set to join the Nationals in St. Louis ahead of the team's three-game set with the Cardinals beginning Tuesday. The catcher was sent down to Triple-A on Friday, but he'll make a quick return to the big-league roster. It's unclear who will be displaced from Washington's roster in a corresponding move.
