Koss went 2-for-4 with a grand slam in Tuesday's 10-6 win over the Diamondbacks.

The Giants fell behind early, but they never looked back after Koss put them ahead with a second-inning grand slam. The infielder has gone 6-for-17 (.353 average) over his last six games, adding six RBI in that span. Overall, he's batting .241 with one home run, seven RBI, six runs scored and no stolen bases over 59 plate appearances on the season. He had nine long balls over 88 minor-league games across three levels last season, so don't expect a lot of power out of Koss. With both Tyler Fitzgerald (rib) and Casey Schmitt (oblique) on rehab assignments, Koss's time as an mainstay in the middle infield for San Francisco could soon come to an end.

Fitzgerald (rib) started at second base and went 1-for-3 with a run scored in Triple-A Sacramento's 5-3 win over Salt Lake on Tuesday.

Fitzgerald began his rehab assignment with Sacramento after being placed on the 10-day IL on May 1 due to a left rib fracture. The 27-year-old infielder hit leadoff and singled in the first inning before coming around to score. Barring any setbacks during his rehab assignment, Fitzgerald could return to the Giants later this week. He has played in 25 games in the majors this season, slashing .284/.341/.432 with 14 runs scored, seven RBI and five stolen bases across 90 plate appearances.

Kim is not in the Dodgers' starting lineup against the Athletics on Tuesday, David Vassegh of AM 570 LA Sports reports.

With Kim beginning Tuesday's contest on the bench, Miguel Rojas will start at second base and bat eighth against Athletics southpaw Jeffrey Springs. Kim was recalled by the Dodgers on May 3 after Tommy Edman (ankle) was placed on the 10-day IL, and Kim has gone 7-for-22 with two stolen bases, four runs scored and two RBI in nine major-league games.

Montes was recalled from Triple-A Durham on Tuesday, Marc Topkin of the Tampa Bay Times reports.

Yandy Diaz was placed on the restricted list in a corresponding move, and the Rays are already undermanned, so Montes could get some playing time in the short term. The 28-year-old utility player slashed .279/.340/.384 with one home run, three steals and a 23.4 percent strikeout rate in 22 games at Triple-A.

McLain will start at second base and bat eighth in Tuesday's game versus the White Sox.

McLain had occupied either the second spot (28 times) or leadoff spot (three times) in his first 31 starts this season, but with a .596 OPS and 31.7 percent strikeout rate, he's earned a trip to the lower third of the Reds' batting order. Santiago Espinal has been elevated to the two hole for Cincinnati.

Fitzgerald (rib) will begin a rehab assignment with Triple-A Sacramento on Tuesday, Justice delos Santos of The San Jose Mercury News reports.

Fitzgerald will play second base and bat leadoff for the River Cats after missing the last couple weeks with a left rib fracture. He shouldn't require too many rehab games before being activated, potentially setting Fitzgerald up for a return later this week if all goes well.

Single-A Fort Myers activated Pena (undisclosed) from the 7-day injured list May 6.

The undersized second baseman missed a little over two weeks with the undisclosed injury and has hit .417 with one double, one strikeout and one caught stealing in four games since getting activated. On the season, Pena is hitting .308 with one home run, two steals, a 7.0 percent strikeout rate and a 2.3 percent walk rate in 43 plate appearances. Pena has hit 52.8 percent of balls on the ground and 45.9 percent to the opposite field, which is a recipe for a high batting average and minimal power.

DeBarge did not suffer a serious injury after getting hit by a pitch in the wrist and should be able to return this week, Aaron Gleeman of The Athletic reports. He hasn't played for High-A Cedar Rapids since suffering the injury Thursday.

DeBarge is having a potential breakout season at High-A by hitting .279/.409/.468 with four home runs and 16 stolen bases in 28 games. Hopefully this injury won't be a significant setback.

The Nationals placed Garcia on the paternity list Tuesday, Andrew Golden of The Washington Post reports.

Garcia will likely miss the remainder of the Nationals' series in Atlanta before rejoining the team Friday in Baltimore. Trey Lipscomb has taken Garcia's roster spot and Amed Rosario will likely handle second base while Garcia is away.

Schneemann started at second base and went 0-for-3 in Monday's 5-0 win over the Brewers.

Schneemann's hot bat since the beginning of May generated more plate appearances for him, and shortstop Brayan Rocchio's demotion to the minors Monday opened up a regular gig. Gabriel Arias will cover short, while Schneemann gets regular starts at second base. Since May 1, Schneemann has a 1.101 OPS with three home runs, two doubles, eight RBI and eight runs scored over 10 contests.
