The Giants optioned Diaz to Triple-A Sacramento on Monday.

The demotion of Diaz opens up a spot on the 26-man active roster for Wilmer Flores (foot), who was reinstated from the 10-day injured list Tuesday in a corresponding move. During his brief stay with San Francisco, Diaz appeared in two games and went 0-for-8 with four strikeouts.

Altuve (heel) remains out of the lineup Tuesday in St. Louis.

Altuve has been held out of action since experiencing discomfort in his heel while legging out a bunt single Saturday at Dodger Stadium. There's no indication that he will require a 10-day IL stint, but Mauricio Dubon is getting another start at second base for the Astros in Tuesday night's series opener against the Cardinals.

Gorman isn't in the Cardinals' lineup Tuesday against Houston.

Gorman is 3-for-7 with an RBI and a run scored across his last two contests, yet he'll sit for the third time in five games Tuesday. Gorman's absence will move Willson Contreras into the DH spot, allowing Andrew Knizner to start behind the plate and bat ninth.

Lowe (back) began a rehab assignment Monday with the Rays' rookie-level Florida Complex League affiliate and went 1-for-3 with a strikeout.

Lowe served as a designated hitter Monday in what was his first game action in three weeks since being shelved with lower-back inflammation. After missing extensive time in 2022 due to a disc herniation in his lower back, Lowe is poised for a shorter absence this time around, though the Rays will presumably still want to see him play second base in a few rehab games before activating him. He'll eventually move his assignment from the FCL to Triple-A Durham before likely rejoining the Rays at some point during the final week before the All-Star break.

Westburg went 1-for-4 with a walk, one RBI and one run scored in Monday's 10-3 win over the Reds.

Westburg also got aboard on a fielder's choice, which accounted for his RBI. The 24-year-old prospect showed a solid eye at the plate with Triple-A Norfolk this year with a 21.3 percent strikeout rate and 9.8 percent walk rate. Getting on base consistently will help him compete for at-bats in a crowded infield, where he's most likely to challenge Adam Frazier and Jorge Mateo for playing time. Westburg can also play corner outfield, but the Orioles are already juggling three players for those two spots.

Semien went 2-for-4 with a solo home run and a walk Monday in a loss to Detroit.

Semien helped the Rangers get off to a good start, swatting a long ball to left field to lead off the bottom of the first inning. However, the Tigers took over from there and won the game handily. Semien finished with his third straight multi-hit contest, and he's gone 7-for-14 over that span. The veteran second baseman has tailed off a bit in June but is still slashing a solid .281/.342/.462 with 11 homers, 55 RBI, seven steals and an AL-high 63 runs on the campaign.

Polanco (hamstring) has been hitting in the cage, taking groundballs and is in the midst of a running progression, Twins trainer Nick Paparesta told the St. Paul Pioneer Press.

Polanco will advance to running the bases next week and then potentially begin a rehab assignment. Polanco missed two weeks in late May with a left hamstring strain and made it less than 10 days before injuring the same muscle. Expect the Twins to take their time with Polanco's recovery as a result.

Ibanez went 2-for-4 with a three-run home run in Monday's win over the Rangers.

Ibanez's fifth home run of the season in the third inning ended up being all the Tigers would need in the 7-2 win. The utility man continues to see regular playing time as he moves across the diamond. He started in right field Monday and has also seen time in left as well as every infield position except for shortstop. Ibanez is hitting .328 with three home runs and an 18.5 percent strikeout rate in 20 games this month while moving into a regular role, but he could start playing less against righties once Akil Baddoo (quad) and Riley Greene (lower leg) return from the injured list.

Kim went 1-for-3 with a solo home run and two walks Sunday in a loss to Washington.

Kim batted out of the leadoff spot for the fourth straight game and was the only Padre to reach base three times. He also hit the team's only homer, going deep to left field in the seventh inning. Kim has been very productive of late, slashing .368/.429/.632 with three homers, seven RBI, nine runs and two steals over 11 games since June 15.

The White Sox optioned Rodriguez to Double-A Birmingham on Monday.

Rodriguez appeared in only one game -- and did not draw a plate appearance -- during his week-long stay on Chicago's major-league roster. The 22-year-old infielder now returns to the Double-A level, where he has posted a .702 OPS with nine homers and nine steals in 44 games this season.
