Lopez agreed to a minor-league contract with the Cubs on Saturday, Tommy Birch of The Des Moines Register reports.

Lopez will report to Triple-A Iowa for what will be his third stint of the season with the Cubs organization. The veteran infielder has appeared in 19 games in the majors with the Cubs and Angels in 2025 but has spent the majority of his time at the Triple-A level. Across stops with the Diamondbacks' and Yankees' Triple-A affiliates, Lopez has slashed .266/.316/.323 with zero home runs and five stolen bases over 41 games.

Alvarez isn't in the lineup for the second game of Saturday's doubleheader against Miami.

After striking out in all four of his trips to the plate during Game 1, Alvarez will remain on the bench for the final half of Saturday's festivities. Luke Williams will get the nod to start at third base instead and bat eighth.

Mauricio isn't in the lineup for Saturday's game against the Brewers.

Mauricio will pick out a seat on the bench Saturday after going 0-for-10 with two walks and four strikeouts to begin the month of August. While he sits, Mark Vientos will start at the hot corner with Starling Marte working as the DH.

Karros went 1-for-3 with a walk and one RBI in Friday's 6-1 loss to the Diamondbacks.

Karros didn't have to wait long to check off a couple of milestones, supplying his first RBI on his first hit, a second-inning single. He'll presumably have plenty of chances to hold down a large share of playing time at third base while Orlando Arcia (elbow) is out. Karros has displayed a quality hit tool in the minors this year, slashing a combined .301/.398/.476 over 75 games between Double-A, Triple-A and a rehab assignment in rookie ball. He's also shown strong plate discipline with a 12.7 percent walk rate and an 18.5 percent strikeout rate, but the power is lacking. Karros has hit just six total homers in the minors this year after supplying a modest 15 long balls in 123 games with High-A Spokane in 2024.

Alexander went 2-for-3 with a home run, a double, a hit-by-pitch and four RBI in Friday's 6-1 win over the Rockies.

Alexander opened the scoring with a three-run double in the first inning before adding a solo shot in the fourth. He's taken over as Arizona's starting third baseman since Eugenio Suarez was traded to Seattle. The increase in playing time has worked well -- Alexander is 8-for-25 (.320) with four extra-base hits over seven games in August. For the season, he's at a .240/.329/.400 slash line with two homers, 10 RBI, 10 runs scored and two stolen bases through 87 plate appearances.

Bohm (ribs) will begin a rehab assignment at Triple-A Lehigh Valley on Sunday, Lochlahn March of The Philadelphia Inquirer reports.

Bohm was placed on the 10-day injured list July 19 due to a left rib fracture but has made enough progress in his recovery to test himself in a game setting. He'll likely need at least a few games in the minors to regain his timing at the plate, but he could be ready to rejoin the Philadelphia lineup by next weekend. While Bohm has been on the shelf, Otto Kemp and Edmundo Sosa have been sharing time at third base.

The Rockies placed Arcia on the 10-day injured list Friday with right elbow inflammation.

Arcia hasn't played since leaving Tuesday's game early with an elbow injury, and he'll officially miss at least another week now that he's on the IL. Kyle Karros and Aaron Schunk were both called up from Triple-A Albuquerque to replenish the Rockies' infield depth, though it's unclear which player will receive the lion's share of the playing time at third base.

The Rockies selected Karros' contract from Triple-A Albuquerque on Friday.

One of the top prospects in Colorado's farm system, Karros has slashed .306/.368/.500 with two homers, four RBI and nine runs scored through 68 plate appearances since being promoted to Triple-A in mid-July. The 23-year-old infielder will now join the major-league roster alongside Aaron Schunk to help make up for the loss of Orlando Arcia (elbow), and Karros will get the nod to make his MLB debut Friday while starting at third base.

Shaw is not in the starting lineup for Friday's game against the Cardinals.

Shaw was swinging a hot bat for a stretch in late July, but he's gone just 3-for-15 to begin August, bringing his season average down to .222 across 287 plate appearances. The 23-year-old will sit for the second time in five games as Willi Castro takes over at third base and bats seventh against right-hander Michael McGreevy.

Alvarez (side) will start at third base and bat eighth Friday against the Marlins.

Alvarez has evidently turned the page on the side soreness that cropped up during Wednesday's contest. Since replacing Austin Riley (abdomen) on Atlanta's active roster, Alvarez has gone 3-for-10 with a pair of doubles and five strikeouts.
