Koss will start at third base and bat ninth in Wednesday's game against the Giants.

Koss will pick up a second straight start at third base in place of Casey Schmitt (knee), who has been diagnosed with a torn meniscus that will likely require season-ending surgery. Though he currently sits atop the depth chart, Koss' run as an everyday player will be short-lived. Giants manager Tony Vitello said that Matt Chapman (abdomen) should be ready to come off the 10-day injured list at some point during the club's series with the Padres later this week, at which point Koss will shift back into a utility role.

Gilbert is out of the lineup for Wednesday's game against the Brewers.

The left-handed-hitting Gilbert was on the bench against a righty (Logan Henderson) for Tuesday's 8-2 loss and will remain out of the lineup again for the series finale while southpaw Thomas Pannone toes the rubber for Milwaukee. Grant McCray will get the start in center field for the second straight day, after he filled in as the starting right fielder in the prior two contests while Jung Hoo Lee managed an elbow injury.

Vaughn is out of the lineup for Wednesday's game against the Giants.

Vaughn was on the bench for the first two games of last weekend's series versus the Rockies, but he started in each of Milwaukee's ensuing three contests and went 3-for-10 with a home run, a walk, two runs and two RBI. With Jake Bauers (foot) back at first base Wednesday following a one-game absence and Luis Lara receiving the start in right field, Vaughn will retreat to the bench for the series finale in San Francisco. Despite playing different positions, Vaughn and Lara appear to be in a quasi-timeshare for the final spot in Milwaukee's regular lineup versus righties, though the Brewers should have room in the starting nine for both players against lefties.

Giants manager Tony Vitello said Wednesday that Chapman (abdomen) will be activated from the 10-day injured list at some point during this weekend's series versus the Padres, Alex Pavlovic of NBC Sports Bay Area reports.

The Giants begin a road trip with a four-game series in San Diego beginning Thursday. Chapman has not played any rehab games, but it appears he'll skip a rehab assignment despite being shelved for the past month. The veteran third baseman is sporting a disappointing .235/.324/.368 batting line with seven home runs in 84 contests for San Francisco this season.

Giants manager Tony Vitello said Wednesday that Schmitt will require arthroscopic surgery for the torn meniscus in his left knee and will "more than likely" miss the rest of the season, Tristi Rodriguez of NBC Sports Bay Area reports.

Vitello said a date hasn't been set for when Schmitt will have surgery, though the 27-year-old is slated to have his procedure performed "as soon as possible." A formal recovery timeline for Schmitt should be provided when the operation is completed, as it's not yet known whether he'll require a meniscectomy or a full meniscus repair. Schmitt would likely face a 3-to-6-week recovery if he requires the former procedure, while a full repair often entails a 4-to-6-month recovery timeline. The 45-62 Giants are well out of the mix for a playoff spot, so Schmitt doesn't look like he'll be rushed back into action even if he gets a meniscectomy and hits no snags in the rehab process. Schmitt had been in the midst of a breakout campaign before suffering the knee injury, slashing .271/.301/.483 with 21 home runs, nine stolen bases, 55 RBI and 47 runs across 409 plate appearances while making starts at all four infield spots in addition to left field.

Drohan is slated to make his next start in Friday's series opener against the Angels in Anaheim, Hunter Baumgardt of Fox Sports 920 Milwaukee reports.

Drohan had been lined up for his 12th start of the season Wednesday in San Francisco, but the Brewers instead decided to call up Thomas Pannone from Triple-A Nashville to make a spot start, which will build in extra rest for all five members of the rotation. The southpaw will miss out on a start in one of baseball's more pitcher-friendly venues in Oracle Park but should still make for a quality option in fantasy lineups this week while taking on an Angels squad that has posted a league-high 25.9 percent strikeout rate against lefties this season.

Bauers (toe) will start at first base and bat third in Wednesday's game against the Giants.

Bauers was diagnosed with a fractured right big toe after fouling a ball off of himself Monday, but he apparently needed just a day off in Tuesday's 8-2 win to improve enough to re-enter the starting nine. The 30-year-old acknowledged Tuesday that he'll still be managing some pain with the toe moving forward, so it wouldn't be surprising if the Brewers ended up building in more off days for him and/or using him at first base more frequently than the corner outfield. The toe issue may also result in Bauers being less active in the running game, where he's contributed eight stolen bases in nine attempts through 97 contests this season.

Contreras is out of the lineup for Wednesday's game against the Giants.

The Brewers will give Contreras a breather for the matinee contest after he caught all nine innings of an 8-2 win Tuesday night. Gary Sanchez will spell Contreras behind the dish in the series finale.

Semien is out of the lineup for the first game of Wednesday's doubleheader with Atlanta.

The veteran second baseman will get a breather for the first contest of the day, but expect him to return to the starting nine for the nightcap. Brett Baty will receive the nod at second base and will bat eighth in Game 1 of the twin bill.

Yastrzemski is out of the lineup for the first game of Wednesday's doubleheader with the Mets.

Lefty Sean Manaea is on the bump for the Mets for the first game of the day, so the left-handed-hitting Yastrzemski will retreat to the bench. Expect Yastrzemski to return to the starting nine for the nightcap, when right-hander Christian Scott will toe the rubber for New York.
