Kopech (knee) threw a bullpen session Friday, James Fegan of The Athletic reports.

EDGE Analysis

Kopech has been on the injured list since Aug. 23 due to a left knee strain, but he's now been cleared to resume mound work. The White Sox hope that he'll be able to return from the IL when first eligible Sept. 7, but the team will wait to see how he progresses in the coming days prior to officially determining his return date.

The White Sox placed Kopech on the 15-day injured list Tuesday with a left knee strain.

EDGE Analysis

After Kopech exited in the first inning of his start during Monday's 6-4 loss to the Royals, manager Tony La Russa said the right-hander was dealing with a hamstring issue, but the White Sox provided an updated diagnosed upon placing the 26-year-old on the IL. The severity of his left knee strain isn't fully known, though the White Sox are tentatively planning on Kopech being ready to return from the shelf when first eligible Sept. 7, per Daryl Van Schouwen of the Chicago Sun-Times. Even if that's the case, Kopech's impending two-week absence could still make it difficult for fantasy managers to justify holding him at this stage of the season. The White Sox called up Tanner Banks from Triple-A Charlotte to provide the team with a multi-inning option out of the bullpen until a replacement in the rotation is needed for Kopech beginning with Saturday's game against the Diamondbacks.

Kopech was removed from Monday's start against the Royals due to a hamstring injury, Daryl Van Schouwen of the Chicago Sun-Times reports.

EDGE Analysis

The White Sox initially announced that Kopech was dealing with a knee injury after he departed Monday's start, but manager Tony La Russa clarified after the game that the right-hander is dealing with a hamstring issue. Kopech will presumably be monitored further in the coming days before the White Sox determine whether he's able to make his next start, which tentatively lines up for Saturday at home against the Diamondbacks.

The White Sox announced that Kopech was removed in the first inning of his start Monday against the Royals with a sore left knee.

EDGE Analysis

Kopech looked to be managing the injury during pregame warmups, as he was checked out by a trainer prior to opening pitch before getting the green light to make the start. In hindsight, the White Sox may have preferred to scratch Kopech, who showed diminished velocity and allowed all four hitters he faced to reach base before being lifted with the bases loaded after throwing 19 pitches. With reliever Jimmy Lambert allowing all three baserunners to score, Kopech was charged with four earned runs on one hit, two walks and a hit batsman. He'll be evaluated in the coming days before the White Sox determine if he's ready to make his next start, which is set to come Saturday at home versus the Diamondbacks.

Kopech was lifted midway through the first inning of his start Monday against the Royals due to an apparent injury he suffered while warming up prior to the game, Vinnie Duber of AllCHGO.com reports.

EDGE Analysis

Kopech failed to retire a batter in the 19-pitch outing, throwing only nine pitches for strikes while allowing four earned runs on one hit, two walks and a hit batsman. Official word on what prompted Kopech's early exit may not come until after the game, but the right-hander looked to be in some discomfort while warming up and was visited by a trainer on the mound before he ultimately tried to give it a go. In addition to his velocity being down during his brief start, Kopech struggled mightily to locate his pitches before manager Tony La Russa pulled him from the contest.

Kopech (4-9) was tagged with the loss against Houston on Wednesday, allowing three runs on five hits and two walks while striking out two batters over six innings.

EDGE Analysis

Kopech wasn't dominant in the outing -- he induced just seven swinging strikes and fanned only two batters -- but he kept Chicago in the game with his third quality start over his past four outings. However, opposing starter Framber Valdez recorded his 20th straight quality start and allowed one fewer run to send Kopech to defeat. Despite the loss, the right-hander continued a recent run of solid pitching -- he has given up three or fewer earned runs in eight of his past 10 starts. He has a poor 43:28 K:BB across 48 innings during that stretch, however, and his strikeout rate has dipped from an impressive 36.1 percent last season to a mediocre 22.4 percent during the current campaign.

Kopech struck out 11 batters through six no-hit innings in Friday's win over Detroit. He walked three and did not factor in the decision.

EDGE Analysis

Kopech was untouchable Friday but he settled for a no-decision due to his offense's slow start. It was his first double-digit strikeout performance of the year and he forced a season-high 22 whiffs. The 26-year-old completed six innings for the second time since the start of July and lowered his season ERA to 3.18 through 104.2 frames. Kopech is projected to take on the Astros at home next week.

Kopech (4-8) gave up four earned runs on five hits and two walks while striking out four over 3.1 innings to take the loss in an 8-0 defeat to the Rangers on Saturday.

EDGE Analysis

Kopech's 97 mph fastball wasn't enough to overpower the Rangers, and he was saddled with his eighth loss of the season after being chased in the fourth inning. The major damage came on a bases-loaded single off the bat of Adolis Garcia. Kopech was also responsible for a runner who came in to score on a wild pitch by reliever Jose Ruiz after he had left the game. Kopech had an ERA of 1.92 on June 12, but the nine starts he has made since that time have lifted it to 3.38. The 26-year-old right-hander will look to rebound in his next start, which is expected to come against the weak Tigers lineup.

Kopech (4-7) took the loss Monday versus the Royals. He allowed two runs on six hits and a walk with three strikeouts in seven innings.

EDGE Analysis

Kopech hadn't allowed a home run in either of his last two starts, but he was tagged for solo shots by Salvador Perez and Whit Merrifield in this contest. The seven innings Kopech pitched matched a season high, and this was the first time in seven starts he didn't walk multiple batters. The right-hander owns a 3.12 ERA, 1.20 WHIP and 81:46 K:BB through 95.1 innings in 19 starts. He's projected for a road start against the Rangers this weekend.

Kopech (4-6) allowed six hits and three walks while striking out four in 5.1 scoreless innings to earn the win Tuesday over the Rockies.

EDGE Analysis

Kopech escaped Coors Field unscathed, even though he permitted nine baserunners for the third time in four starts. The White Sox took the lead in the fourth inning, and held onto it to given Kopech consecutive wins for the first time this year. He's posted a steady 3.16 ERA with a 1.21 WHIP and 78:45 K:BB through 88.1 innings in 18 starts. The right-hander is projected for a favorable home start versus the Royals next week.
