Koss went 1-for-3 with a two-run home run in Tuesday's 4-2 loss to the Marlins.

EDGE Analysis

Koss took Miami starter Cal Quantrill deep in the fifth inning to pull the Giants within a run. Koss has started three of the Giants' last five games, all against right-handed pitchers, but it's too soon to tell how the playing time will shake out at second base in the short term after Tyler Fitzgerald was demoted to Triple-A Sacramento on Monday. Koss is in the mix, but the right-handed hitter will be competing with the left-handed-hitting Brett Wisely until Matt Chapman's (hand) return shifts Casey Schmitt over to the keystone. Koss hasn't done much in his first year in the majors, slashing .224/.272/.303 with two homers, 11 RBI, eight runs scored and a stolen base over his first 84 plate appearances.

The Giants recalled Koss from Triple-A Sacramento on Tuesday, Shayna Rubin of the San Francisco Chronicle reports.

EDGE Analysis

The 27-year-old was demoted last week but will rejoin San Francisco with Matt Chapman (hand) landing on the injured list. Koss has a .219/.275/.266 slash line over 72 plate appearances in the majors this season and will likely fill a reserve role while up with the big club.

The Giants optioned Koss to Triple-A Sacramento on Wednesday, Shayna Rubin of the San Francisco Chronicle reports.

EDGE Analysis

Koss has slashed just .219/.275/.266 this season and had seen limited playing time recently. He should see more regular reps at Sacramento as a utility infielder.

Koss is out of the lineup for Wednesday's game against the Royals, Shayna Rubin of the San Francisco Chronicle reports.

EDGE Analysis

Koss had served as the Giants' primary second baseman through the first two weeks of May, but his starting opportunities are likely to be scarcer moving forward after Tyler Fitzgerald and Casey Schmitt were both activated from the injured list within the past few days. Fitzgerald will get the nod at the keystone Wednesday while Koss hits the bench for the fifth time in the last six games.

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

EDGE Analysis

The Giants fell behind early, but they never looked back after Koss put them ahead with a second-inning grand slam. This was his first multi-hit effort as a major-leaguer. The infielder is 6-for-17 (.353) over his last six games, adding six RBI and a 1:5 BB:K in that span. Overall, he's batting .241 with a .589 OPS, one homer, seven RBI, six runs scored and no stolen bases over 59 plate appearances. He had nine homers 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 in the majors could be nearing a close.

Koss is out of the lineup for Sunday's game against the Twins.

EDGE Analysis

Brett Wisely will step in at the keystone while Koss takes a seat following a stretch of three consecutive starts. Since Tyler Fitzgerald (rib) joined Casey Schmitt (oblique) on the injured list May 1, Koss has started at second base in seven of the Giants' first 10 games this month while going 5-for-23 (.217) with no extra-base hits or stolen bases.

Koss will start at second base and bat ninth in Sunday's game against the Rockies.

EDGE Analysis

Koss will occupy the keystone for the third time in four games and could get a look as the Giants' primary option at the position after Tyler Fitzgerald (rib) joined Casey Schmitt (oblique) on the injured list. After making the Giants' roster out of spring training, Koss had seen limited playing time through the end of April, logging just 26 plate appearances over the team's first 31 games. Along with Koss, Brett Wisely is also in the mix for playing time at second base while Fitzgerald and Schmitt are on the shelf.

Koss went 1-for-3 with an RBI in Sunday's 3-2 win over the Rangers.

EDGE Analysis

Koss lined a two-out RBI single into left field to tie the game at 2-2 in the fourth frame. The 27-year-old infielder owns a .333 batting average in his last five appearances after hitting .143 in his first seven. Koss has recorded a hit in each of the Giants' previous two games, receiving the starting nod at second base while Tyler Fitzgerald recovers from a chest contusion. Koss is now slashing .217/.280/.217 with four runs scored and a 1:8 BB:K across 26 plate appearances.

Koss went 1-for-4 with a run scored during Sunday's 5-4 win over the Yankees.

EDGE Analysis

Koss started at second base for the third time this season, recording his first big-league hit before coming around to score on a three-run home run by Jung Hoo Lee in the sixth frame. Koss has played in five games during the 2025 campaign, scoring two runs across 11 plate appearances. The 27-year-old infielder is slashing .100/.182/.100 with a 1:4 BB:K so far this season.

Koss went 0-for-3 with a walk and a run scored in Tuesday's 3-1 win over the Astros.

EDGE Analysis

Koss drew the start at second base during his big-league debut. The 27-year-old reached first on a walk in the third frame and displayed his speed by scoring from first on a two-run double by Willy Adames. Koss is expected to operate as a utility infielder for the Giants this season, though he's a candidate to receive playing time in the outfield as well, per Shayna Rubin of the San Francisco Chronicle.
