Koss went 1-for-3 with a double and a run scored in Monday's 5-2 win over the Twins.
Koss lined a double to left field in the second inning before coming around to score. The 28-year-old had gone hitless in the Giants' previous three games, though he's been productive in September, batting .297 on the month with 15 runs scored, eight RBI, three home runs and three stolen bases in 69 plate appearances. Overall, he's slashing .230/.273/.326 with 27 runs scored, 12 RBI, five stolen bases and four long balls across 203 plate appearances this season.

Koss went 2-for-4 with an RBI, a run scored and two steals in Sunday's 6-4 loss against San Diego.
Koss collected a pair of singles, swiping second and third base after his knock to lead off the fifth inning. The 28-year-old has seen regular playing time at shortstop with Willy Adames (elbow) sidelined and has taken advantage of the opportunity, slashing .359/.419/.590 with three homers, six RBI, 13 runs and three stolen bases over his past 12 games. His season-long numbers are much more pedestrian, as Koss is hitting .235/.283/.340 with four homers, 10 RBI, 25 runs and five stolen bases in 59 total contests.

Koss went 2-for-3 with a solo home run in Tuesday's 2-1 win over the Cardinals.
Koss has four homers this season, all coming over his last 12 contests. He's batting .250 (10-for-40) with seven RBI in that span. The infielder is batting .219 with a .594 OPS, nine RBI, 22 runs scored, five doubles and two stolen bases over 164 plate appearances this season, so the recent power surge is a bit of a surprise. Koss should continue to see steady playing time in the infield to close out the campaign, though that could change if Willy Adames (elbow) or Marcelo Mayer (forearm) come off the injured list.

Koss went 2-for-4 with two home runs and three RBI in Saturday's 9-5 win over the Mets.
Both homers came off Zac Thornton, with Koss belting a two-run shot in the third inning and a solo blast in the fifth. The shortstop has flipped the switch at the plate in September -- he entered the month with a .498 OPS in 47 big-league contests, but over the last five games he's gone 6-for-19 (.316) with two homers, a walk, four RBI and eight runs.

Koss went 1-for-3 with a two-run home run in Friday's 10-6 loss to the Diamondbacks.
Koss has gone 16-for-60 (.267) over his last 18 games, adding a homer and four doubles in that span. The infielder has taken over a starting role at shortstop in the absence of Willy Adames (elbow), who could miss the rest of the season after going down with the injury Sunday. Over 123 plate appearances this season, Koss is batting .211 with a .537 OPS, one homer, four RBI, 12 runs scored, five doubles and two stolen bases, so he's unlikely to hit his way into the picture in fantasy.
