The Giants reinstated Koss (hamstring) from the injured list Friday.
EDGE Analysis
Koss landed on the injured list at the beginning of July with a left hamstring strain but looked pretty good during his five-game rehab assignment, going 9-for-22 at the plate with a home run, six RBI and five runs scored. Now fully healthy, he'll reclaim a spot on the Giants' bench and replace Brett Wisely on the 26-man roster.

Koss (hamstring) had his rehab assignment transferred to Triple-A Sacramento on Saturday, and he went 1-for-5 with an RBI double in the team's 5-4 win over Las Vegas.
EDGE Analysis
Koss began his rehab stint in the rookie-level Arizona Complex League on Thursday but was quickly moved to Triple-A. The 27-year-old reserve infielder was placed on the 10-day injured list July 1 due to a left hamstring strain, but his quick progression from Arizona to Sacramento bodes well for a quick return to the big leagues.

Koss (hamstring) is set to resume baseball activities this week and be re-evaluated after the All-Star break, per MLB.com.
EDGE Analysis
Koss was placed on the 10-day injured list July 1 due to a left hamstring strain. The 27-year-old infielder will use the All-Star break to continue his recovery before the Giants determine his next steps, though his return to baseball activities is an encouraging sign. Koss has been effective in a reserve role for the Giants, slashing .265/.305/.357 with 12 runs scored, 12 RBI, two home runs and two stolen bases across 108 plate appearances.

The Giants placed Koss on the 10-day injured list Tuesday with a left hamstring strain, Justice delos Santos of The San Jose Mercury News reports.
EDGE Analysis
Koss had to make an early exit from Monday's game after injuring his hamstring during his third at-bat, and he'll now be forced to sit out at least another 10 days. With Matt Chapman (hand) and Casey Schmitt (wrist) also on the IL, Wilmer Flores is likely to see some time at third base in the near future. Meanwhile, Luis Matos will come up from Triple-A Sacramento to replenish the Giants' bench depth.

Koss suffered a left hamstring injury in Monday night's 4-2 loss to the Diamondbacks and will not play Tuesday, Justice delos Santos of The San Jose Mercury News reports.
EDGE Analysis
Koss grounded out to shortstop in his third at-bat of the game but was able to stay in and later hit a ground-rule double in the top of the eighth, only to have Brett Wisely pinch-run for him. It's unclear if Koss will need to head to the injured list. San Francisco is hurting at third base, with both Matt Chapman (hand) and Casey Schmitt (wrist) already on the 10-day IL. Wisely would figure to be the next man up at the hot corner for the Giants.

Koss went 2-for-3 with a double, a run scored, a stolen base and a walk in Sunday's 5-2 loss to the White Sox.
EDGE Analysis
The 27-year-old made his sixth straight start Sunday, including his fourth straight at third base due to Casey Schmitt (wrist) being sidelined. Koss drew a walk in the second inning and subsequently stole second before coming around to score the Giants' first run. He also lined a double to left field in the fourth and added a single in the eighth. The infielder has recorded two hits in each of his last four games, slashing .533/.563/.667 with three runs scored, two doubles and a stolen base across 16 plate appearances during that span.

Koss will start at third base and bat seventh in Sunday's game against the White Sox.
EDGE Analysis
Koss will pick up his sixth straight start, including his fourth in a row at third base with Casey Schmitt (wrist) still not ready to return to the lineup. Schmitt is scheduled to undergo an MRI on Monday and could still land on the injured list, which would allow Koss to retain a regular spot in the starting nine. If Schmitt is back in action in the coming days however, Koss would vie with Brett Wisely for playing time at second base.
