The Athletics reinstated Gelof (ribs) from the injured list Friday.

Gelof landed on the injured list at the start of the season due to a hamate fracture, but he suffered a stress reaction in his ribs while on assignment in May, extending his time on the shelf. Now completely healthy, he'll rejoin the active roster and take over as the Athletics' primary second baseman. Luis Urias (hamstring) was placed on the IL in a corresponding move. Gelof is batting eighth in his season debut against San Francisco on Friday.

The Guardians have assigned Bazzana (oblique) to the Arizona Complex League to begin a rehab assignment, per SI.com.

Bazzana suffered a right oblique strain in mid-May and hasn't played since then. He resumed baseball activities in late June and has now been deemed able to return to game action. Bazzana will presumably head back to Double-A Akron -- with whom he posted a .795 OPS across 33 games before getting hurt -- when he's completed the rehab assignment.

Gimenez (ankle) is back in the lineup for Friday's game against the Angels.

Gimenez seems to have already turned the page after an ankle issue forced him from Wednesday's game and kept him on the bench for Thursday's series finale against the Yankees. He will slot in atop the batting order, with Bo Bichette batting third against right-hander Kyle Hendricks in the absence of Vladimir Guerrero (foot).

Tawa started at first base and went 0-for-3 in a 7-2 loss to the Giants.

Tawa filled in for Josh Naylor, who was held out against San Francisco lefty Robbie Ray. Naylor, who recently experienced neck stiffness, had just returned to the starting lineup Wednesday as the designated hitter, and the decision to sit him Thursday does not appear to be injury related. Tawa has gone hitless over his last 24 at-bats while striking 10 times (41.7 percent strikeout rate).

Torres went 2-for-4 with a walk, an RBI and a run scored in Thursday's 11-7 loss to the Nationals.

Torres has been locked in lately, going 12-for-40 (.300) over his last 10 games with two home runs, six RBI and 10 runs scored. That strong play has earned the second baseman a starting nod in the All-Star Game in his first season with the Tigers, and he's poised for a productive second half batting ahead of powerful hitters such as Riley Greene and Spencer Torkelson.

Schneemann started at second base Thursday against the Cubs and went 1-for-4 with a strikeout.

The 28-year-old came off the bench to fill in at shortstop for Gabriel Arias (ankle) on Sunday, but Brayan Rocchio has stepped in as Cleveland's shortstop with Arias now on the injured list. Schneemann has seen most of his action at second base this season but also has multiple starts at shortstop, third base and all three outfield spots. He finished May with a .779 OPS but is batting just .188 (12-for-64) with four extra-base hits since the start of June.

Marte went 1-for-4 with a solo home run in Thursday's 7-2 loss to the Giants.

Marte has homered in back-to-back games for the third time in the last two weeks. In that span dating back to June 20, he has gone 17-for-51 (.333) with seven homers and 16 RBI. This power surge has the second baseman closing in on a third straight 20-homer season -- he's at 19 for the year while adding a .299/.402/.603 slash line, 40 RBI, 50 runs scored and two stolen bases across 61 games. If he can stay healthy in the second half, he could take a run at his career high of 36 homers from last year.

Estrada went 3-for-4 with a two-run home run, two additional RBI and a run scored in Thursday's 7-6 win over Houston.

Estrada got the Rockies on the board with a two-run homer in the first inning and kept Colorado in the game with RBIs in the third and seventh. Estrada has logged at least three hits in four of his last six starts and has gone 12-for-26 (.462) with one steal and eight RBI over that span. He is slashing .317/.339/.436 with two home runs and 18 RBI over 109 plate appearances this season.

Rojas (finger) is starting and third base and batting ninth Thursday against the White Sox.

Rojas appeared to injure his finger by jamming it on a stolen-base attempt Sunday in Kansas City and left the game early. After not appearing in the first two games of the series against the White Sox, he is in the lineup Thursday in place of Max Muncy (knee) at third.

Turang isn't in the lineup for Thursday's game against the Mets.

Turang slashed .421/.452/.579 with 10 RBI and 11 runs scored during his 14-game hitting streak, which came to an end when he went 0-for-4 with three strikeouts in the second game of Wednesday's doubleheader. He'll get a chance to rest during Thursday's series finale in Queens while Andruw Monasterio starts at second base and bats ninth.
