Singleton will start at first base and bat fifth in Monday's game against the Blue Jays, Matt Kawahara of the Houston Chronicle reports.

Singleton looks to have indirectly overtaken Joey Loperfido for a regular spot in Houston's typical lineup versus right-handed pitching. Though Mauricio Dubon had been poaching playing time from Singleton at first base, Dubon has now made his last three starts at second base, left field and right field while Singleton has covered first base in each of those contests and Loperfido has been on the bench. Singleton closed June on a high note, going 7-for-16 with a home run, a walk, four RBI and two additional runs over his last five games.

Guerrero (hand) will start at first base and bat third in Monday's game against the Astros.

Guerrero was hit in the right hand by a pitch in the third inning of Sunday's 8-1 loss to the Yankees, but he proceeded to stay in the game until he was lifted for a pinch hitter in the bottom of the eighth. X-rays on Guerrero's hand came back negative, and his removal from the contest might just have been precautionary while the Blue Jays faced a seven-run deficit at the time of his exit. Even with a quick turnaround for Monday's Canada Day game that begins at 3:07 p.m. ET, the Blue Jays evidently felt comfortable enough with Guerrero's health to insert him back in the lineup.

Lowe went 2-for-5 with two RBI and two runs scored in Sunday's 11-2 win over the Orioles.

Lowe was part of the Rangers' offensive explosion Sunday and finished the month on an upswing. He went 8-for-21 (.381) with a double, two home runs, eight RBI and three additional runs scored over the final five games of June.

Pasquantino went 3-for-4 with one RBI and one run scored in Sunday's 6-2 win over the Guardians.

Pasquantino has gone 11-for-27 (.407) with nine RBI across his last seven games, ending June on a high note. The first baseman's recent surge has him up to a .247/.321/.436 slash line for the year, nearly identical to his marks over 61 contests in 2023. He's added 10 home runs, 55 RBI, 39 runs scored, 21 doubles and two triples through 82 games this year, playing on a near-everyday basis between first base and designated hitter.

Singleton went 3-for-4 with a solo home run Sunday against the Mets.

Singleton took Mets starter Luis Severino deep in the second inning for his sixth homer of the season and first in over a month. The first baseman later added two more hits, giving him his first three-hit game of the season. Through 59 games, Singleton has accumulated 205 plate appearances, totaling six home runs, three doubles, 18 RBI, 23 runs and a 26:53 BB:K.

Mountcastle was unavailable for Sunday's 11-2 loss to the Rangers due to an illness, Matt Weyrich of The Baltimore Sun reports.

Mountcastle's absence from the lineup was a surprising one Sunday considering his impressive .306/.359/.494 slash line against left-handed pitchers this season, but manager Brandon Hyde clarified after the contest that Mountcastle was feeling under the weather. With Baltimore off Monday, there's a good chance that Mountcastle will be ready to go for the team's series opener in Seattle on Tuesday.

Vaughn went 2-for-4 with a solo home run, a walk and two additional RBI in Sunday's 5-4 loss to the Rockies.

Vaughn tied the game in the seventh inning with an RBI walk before knotting the game up in the 10th inning with a sacrifice fly. The 26-year-old quietly had an impressive month of June, batting .337 with six home runs, 20 RBI and 17 runs scored in 25 games played.

Guerrero had X-rays on his right hand come back negative after being hit by a pitch during Sunday's 8-1 loss to the Yankees, Hazel Mae of Sportsnet reports.

The 25-year-old remained in the contest after being hit by the pitch during the third inning, but he was eventually pulled for a pinch hitter. He finished the day 1-for-2 with a base hit. Guerrero appears to have avoided a serious injury and should be considered day-to-day heading into Monday's series opener against Houston.

Mountcastle is out of the lineup for Sunday's game against the Rangers, Roch Kubatko of MASNSports.com reports.

The 27-year-old's omission from the lineup is surprising since southpaw Andrew Heaney is taking the mound for Texas. Mountcastle has an .853 OPS versus lefties this season and was also held out of the lineup for Saturday's contest, so it's possible he's dealing with an injury or illness, though nothing has been reported at this point. The lefty-hitting Ryan O'Hearn will instead start at first base Sunday.

Davis was scratched from Sunday's lineup against the Blue Jays.

The 31-year-old probably is perfectly healthy, but Juan Soto's (hand) late addition to the starting nine will bump Davis from the lineup. He's gone 1-for-9 with a double, two walks, an RBI and a run in three games since being acquired by the Yankees last weekend.
