Kopech earned the save in Friday's 5-3 win over the Rockies, pitching a scoreless inning and working around a walk.

EDGE Analysis

The 28-year-old entered the ninth with a two-run lead and looked to immediately be in danger as he opened with six-pitch walk to Ryan McMahon. However, Kopech induced two consecutive groudouts, including one of the double-play variety, to escape with just his second save in June. The Chicago right-hander lowered his season ERA to 4.46 over 34.1 innings as he appears to have seized control of the closer's role over John Brebbia for the time being.

Kopech struck out one while not allowing a hit or a walk during the ninth inning Thursday to pick up the save against Atlanta.

EDGE Analysis

A fielding error is all that prevented a 1-2-3 outing from Kopech, who collected his first save since May 15 after having blown his previous three opportunities. Kopech carries an impressive K/9 rate of 13.0, collecting 48 strikeouts over 33.1 innings. However, he's also allowed 48 batters to reach base (1.44 WHIP), including allowing 1.9 homers and 5.1 walks per nine innings. Kopech is a piece the White Sox will strongly consider selling at the trade deadline and will look for more performances like he provided Thursday to help them maximize the return they might get for him.

Kopech allowed one hit and walked one while striking out two across a scoreless ninth inning Saturday against the Tigers.

EDGE Analysis

Kopech entered the game with a four-run lead and allowed consecutive batters to reach base with two outs. He managed to escape to turn in his second consecutive scoreless appearance, though he's still allowed eight earned runs across his last 8.1 frames. Those struggles have called Kopech's role as closer into question, though he did enter Saturday's game after John Brebbia.

Kopech (2-6) blew a save but earned the win over the Mariners on Thursday, allowing one run on one hit while striking out two batters over one inning.

EDGE Analysis

Kopech was summoned in the ninth inning to try to protect a one-run Chicago lead but served up a one-out, game-tying solo shot to Julio Rodriguez. To his credit, Kopech bounced back to retire the next two batters and send the game to extra frames, and he was credited with a win as a result of the White Sox pushing across a run in the 10th. Kopech hasn't been very effective in a closing role for Chicago -- he hasn't notched a save since May 15 and is just 5-for-9 in save opportunities this season. He has a 4.91 ERA and 1.50 WHIP over 29.1 innings, though his 13.2 K/9 is characteristic of what most teams look for from a closer.

Kopech struck out two and walked one without allowing a hit in a scoreless ninth inning Wednesday against the Mariners.

EDGE Analysis

Kopech imploded to allow three earned runs and blow a lead in an appearance Monday, but he managed to bounce back in this outing. He entered the game with the score tied at 1-1 and turned in just his third scoreless effort in his last five appearances. Kopech remains the White Sox's primary closer, though his last save came on May 15.

Kopech allowed one hit and one walk while striking out two across a scoreless ninth inning Saturday against the Red Sox.

EDGE Analysis

Kopech was called upon to protect a five-run lead. He did so successfully, though he allowed three hitters to reach base -- he hit a batter in addition to the walk and hit he surrendered -- and required 33 pitches to retire the side. Though it was shaky, the outing was still positive for Kopech as he had allowed at least one run in three of his last four appearances entering Saturday.

Kopech (1-6) allowed a solo home run to the only batter he faced, taking the loss Wednesday versus the Cubs.

EDGE Analysis

Kopech was taken deep by Mike Tauchman as the Cubs won in walk-off fashion. It's been tough sledding for Kopech lately -- he's allowed five runs (four earned) over his last 2.2 innings, taking the loss in three of his last four appearances. The right-hander is now at a 4.21 ERA, 1.36 WHIP and 35:15 K:BB through 25.2 innings while adding five saves, a hold and two blown saves. If he continues to struggle, Kopech could eventually lose his high-leverage role, though the White Sox's poor play overall has made it difficult for any of the team's relievers to put up saves.

Kopech (1-5) allowed one run (none earned) on one hit and one walk while striking out two to take the loss Saturday against the Brewers.

EDGE Analysis

Kopech entered the game in the 10th inning with the game tied at three. He intentionally walked the first batter he faced to put a pair of runners on base before throwing a wild pitch and allowing an infield single to take the loss. Kopech has had an inconsistent season, though he did turn in scoreless efforts in eight of his nine appearances in May. The White Sox haven't converted a save since May 15, but he should be considered the team's primary closer for the time being.

Kopech (1-4) blew the save and took the loss Saturday, giving up three runs on three hits in two-thirds of an inning as the White Sox fell 5-3 to the Orioles. He struck out one.

EDGE Analysis

Chicago rolled into the eighth inning with a 3-0 lead, but after Jordan Leasure served up a two-run homer to Ryan O'Hearn, Kopech got the call and threw more gas on the fire, getting taken deep himself by Anthony Santander and Jordan Westburg. Kopech has been tagged for five home runs in 23.2 innings this season, fueling a 4.18 ERA, and his issues keeping the ball in the park have followed him to the bullpen. He'll continue to get the majority of the save chances for the White Sox, but his reliability as a high-leverage reliever is still in question.

Kopech struck out the side without allowing a baserunner Tuesday against the Blue Jays.

EDGE Analysis

Kopech entered the game in the ninth inning and was tasked with protecting a five-run lead. He needed only 15 pitches to end the game, and he racked up seven called strikes without generating a whiff. After a shaky start to the season, Kopech now has six consecutive scoreless appearances, maintaining an 8:5 K:BB across 6.1 frames in that span.
