Kopech will start Sunday's game against the Rangers, Scott Merkin of MLB.com reports.

EDGE Analysis

Lucas Giolito was expected to work Sunday's game, but the team will instead opt to give Kopech his second start of the season. Kopech threw only 41 pitches across three innings in his first start of the campaign, leaving it unclear how deep he will be able to work this time around. On the other hand, he's provided quality innings while on the mound, amassing a 1.69 ERA with a 17:4 K:BB across 10.2 frames.

Kopech allowed one run on one hit and one walk while striking out four over three-plus innings in a 5-1 win over the Red Sox in the second game of Sunday's doubleheader.

EDGE Analysis

Kopech set down the first nine batters before Enrique Hernandez walked and Alex Verdugo singled to lead off the fourth inning. That ended Kopech's night at 41 pitches. Manager Tony La Russa said Kopech would pitch at most three innings, pending his pitch count, but trotted him out there to start the fourth given his efficiency over the first three frames. An obvious leap following the game is that Kopech could get another start for Lance Lynn (back), who was placed on the injured list Sunday and will miss at least one start, but La Russa put a damper on that notion. "Down the road he'll be in the rotation," La Russa told Daryl Van Schouwen of the Chicago Sun-Times. "But [first] he's going to be a force coming out of our bullpen."

White Sox manager Tony La Russa said Kopech will start the second game of Sunday's doubleheader with the Red Sox, Jesse Rogers of ESPN.com reports.

EDGE Analysis

Facing off against the organization that selected him with the 33rd overall pick in the 2014 first-year player draft, Kopech will be making his first MLB start since Sept. 5, 2018. Kopech has been dynamic in his four extended relief appearances for Chicago this season, allowing one run on two hits and three walks over 7.2 innings while striking out 13. According to James Fegan of The Athletic, La Russa said Kopech will likely work up to three innings if he's efficient with his pitch count, so the right-hander may have a tough time factoring into any decision. The White Sox designated Jonathan Stiever as their 27th man for the twin bill, and he could end up piggybacking Kopech in the outing.

Kopech has been bouncing back strong from his multi-inning relief appearances and would have been an option to start Monday for Carlos Rodon (illness) had he not pitched the day before, Daryl Van Schouwen of the Chicago Sun-Times reports.

EDGE Analysis

The White Sox no longer have a vacancy in the rotation, as Rodon is set to start Wednesday, but it's encouraging to know that Kopech could be an option in the future. He has dominated to the tune of 6.1 scoreless frames in three appearances, striking out 11 and walking two over that span.

Kopech struck out three over 2.1 scoreless innings in Sunday's extra-inning loss to the Royals.

EDGE Analysis

Kopech breezed through Kansas City's batters, retiring seven straight on 26 pitches. He's handled the transition to relief with aplomb, allowing just one hit and two walks while striking out 11 and retiring 19 of 22 batters faced over 6.1 innings. The right-hander's made three appearances, all spaced out and allowing rest to handle the rigors of multiple innings. Kopech's thrown no fewer than two innings each of his three outings.

Kopech (1-0) walked one and struck out three over two-plus scoreless innings to pick up the win over the Angels on Friday.

EDGE Analysis

It looked like this would be Matt Foster's win after he finished up the fifth inning for starter Dallas Keuchel, but he allowed two inherited runners to score, albeit on a three-base error by right fielder Adam Eaton. So, the win went to Kopech, who entered in the sixth inning and made his first regular-season appearance since Sept. 5, 2018. He pitched two perfect innings before walking Mike Trout to lead off the eighth inning. The right-hander threw 33 pitches (21 strikes) and maxed out at 99.4 MPH.

Kopech allowed two hits and struck out two over 1.1 innings in Monday's spring game against the Giants.

EDGE Analysis

Kopech entered the game in relief of Lucas Giolito and stranded the two runners he inherited to end the fifth inning. He followed that up with a bases-loaded strikeout (looking) to end the sixth. The right-hander, who has allowed one run and struck out seven over 5.1 spring innings, will serve as a reliever to start the 2021 season.

Kopech (calf) allowed a hit, hit a batter and struck out two in one scoreless inning against the Cubs on Monday.

EDGE Analysis

Kopech had his most recently scheduled outing delayed due to tightness in his calf. His fastball hit 100 mph and sat in the high 90s Monday, but it was the right-hander's slider that induced the two punchouts, per Scott Merkin of MLB.com. "I felt comfortable attacking the zone with my secondary pitches, which is something I've really been working on," Kopech said. "Coming out of the bullpen, getting loose that way, I'm starting to -- I wouldn't say get used to it, but get a feel for it." Kopech will be used out of the bullpen initially but could emerge in the rotation later in the season.

Kopech (calf) is expected to pitch during Monday's Cactus League matchup against the Cubs, Scott Merkin of MLB.com reports.

EDGE Analysis

Kopech experienced calf tightness Friday and threw a side session rather than pitching in the spring game against the Rangers. Manager Tony La Russa said that the right-hander didn't experience any calf issues Saturday, and he'll return to Cactus League action Monday as a result.

Kopech threw a side session Friday rather than pitching in the spring game against the Rangers after experiencing calf tightness, James Fegan of The Athletic reports.

EDGE Analysis

The fact the 24-year-old still had a throwing session indicates the calf issue is minor, though it's still somewhat worrying to have an injury crop up so close to Opening Day. Kopech should be considered day-to-day until he's able to return to game action.
