Kopech walked two and struck out two in a scoreless ninth inning Wednesday to record his fifth save of the season in a 2-0 win over the Nationals.

EDGE Analysis

After working a scoreless frame in the nightcap of Tuesday's doubleheader in a non-save situation, Kopech was called upon again and labored through 33 pitches (20 strikes) before finally getting the job done. The last time the right-hander pitched on back-to-back days, he got the next four days off, so Kopech could be unavailable at least until the weekend. Through 19 appearances this season, he sports a 3.32 ERA, 1.29 WHIP and 29:14 K:BB through 21.2 innings.

Kopech allowed two walks and struck out one across a scoreless ninth inning in the second game of Tuesday's doubleheader against the Nationals.

EDGE Analysis

Kopech entered the game in the ninth inning with a four-run lead and successfully closed out the game. It was his first appearance since May 9, and he struggled with his control, walking a pair and also throwing a pair of wild pitches. Despite being shaky in this appearance, Kopech has now allowed only one earned across his last 7.1 innings.

Kopech earned a save against the Guardians on Thursday, allowing one hit and striking out one batter over 1.1 innings.

EDGE Analysis

Kopech's save against Tampa Bay on Wednesday was relatively stress-free, as he entered with a three-run lead. That wasn't the case Thursday -- Kopech was asked to put out a fire in the bottom of the eighth frame after Cleveland slugged back-to-back homers to get to within a run. The right-hander retired David Fry in that inning to quell Cleveland's momentum, then worked around a one-out single in the ninth to finish off the save. The White Sox are among the worst teams in the majors this season, so Kopech may not have as many save opportunities as closers on contenders, but he's emerged the Chicago's clear go-to ninth-inning option with a save in consecutive contests.

Kopech registered a save against the Rays on Wednesday, allowing one hit in one scoreless inning.

EDGE Analysis

Kopech had a relatively easy time closing things out with a three-run lead Wednesday -- though he gave up a one-out infield single, the right-hander got the next batter to ground into a game-ending double play. It was the third save of the season for Kopech, though his most recent save prior to Wednesday came all the way back on April 9. Four different pitchers have notched a save for the White Sox this season, but Kopech appears to be the team's primary closer, as he's the only one among the four with multiple save conversions.

Kopech (1-3) threw a scoreless ninth inning while allowing one walk and striking out one to earn the win Saturday against the Cardinals.

EDGE Analysis

Kopech entered the game in the ninth inning with the score tied 5-5. He struggled with his control -- he hit a batter in addition to the free pass he issued -- but ultimately escaped for this third scoreless effort in his last four appearances. Despite a shaky start to the season, Kopech remains the White Sox's primary option in the highest leverage situations, often including save chances.

Kopech allowed two earned runs on two hits and no walks while striking out two to earn a hold Tuesday against the Twins.

EDGE Analysis

Kopech was used in the eighth inning, and he primarily matched up against the top of the Twins' lineup. He allowed a leadoff single and later in the inning served up a two-run home run to Trevor Larnach. Kopech still maintained a one-run lead for the White Sox to earn his first hold of the season. The sample of the team maintaining a lead late in games is small, but it appears that manager Pedro Grifol is comfortable using Kopech in the highest-leverage situations rather than using him solely in save situations.

Kopech threw a scoreless inning during which he didn't allow a baserunner and struck out two Sunday against the Phillies.

EDGE Analysis

Kopech made his first appearance since blowing a save chance Wednesday. While it wasn't in a save situation, Kopech was nevertheless impressive, retiring the side on 13 pitches while generating three swinging strikes. He's now turned in six scoreless performances in nine appearances this season, also maintaining a 17:6 K:BB across 11.1 innings.

Kopech (0-2) blew a save and ultimately took the loss in Wednesday's opening game against Kansas City, allowing two runs on two hits while striking out one.

EDGE Analysis

Called upon to protect a one-run lead in the eighth inning, Kopech gave up a one-out single to Bobby Witt before Salvador Perez launched a two-run homer, sticking Kopech with his first blown save and the loss. The right-hander has already earned a pair of multi-inning saves this season, so it's likely this was Chicago's intention again Wednesday. Overall, Kopech is 2-for-3 in save chances this year with a 3.48 ERA, 1.26 WHIP and 15:6 K:BB through his first 10.1 innings.

Kopech earned the save in Tuesday's 7-5 win over the Guardians, striking out four over two perfect innings.

EDGE Analysis

Kopech looked excellent Tuesday, striking out the side in the eighth inning before setting the Guardians down in order in the ninth to nail down his second save this year. The right-hander had allowed a run in each of his prior two appearances, issuing four walks over 2.2 innings in that span. Tuesday's performance was certainly a step in the right direction for Kopech, who appears to be the White Sox's primary closer early in the year. Overall, he's 0-1 with a 2.45 ERA, 1.23 WHIP and 12:5 K:BB through his first 7.1 innings this season.

Kopech (0-1) allowed one earned run on one hit and two walks while striking out three to take the loss Friday against the Royals.

EDGE Analysis

Kopech entered the game in the eighth inning of a tied contest and walked the second batter he faced, which ultimately became the game-deciding run. He's now walked five batters across his first 5.1 innings of work, resulting in a 1.69 WHIP. Kopech's usage was also particualrly notable, as he was deployed in the perceived highest-leverage situation rather than being reserved for a save chance. He's still likely to regularly serve as the closer for the White Sox, though the door could be open for another reliever to pick up a handful of saves.
