2023 Fantasy Outlook
Kopech returned to a big-league mound in 2021 for the first time in three years and excelled as a reliever, and he continued that success in the starting rotation last year. The right-hander made only 19 starts while he dealt with knee and shoulder issues, but when available he pitched well with a 3.54 ERA, 1.19 WHIP and 105:57 K:BB across 119.1 innings. He unsurprisingly saw his velocity drop 2.5 mph from his year out of the bullpen, and with it his strikeout rate dropped from 36.1 percent to 21.3 percent. The underlying numbers are a bit less encouraging, as he had a 4.83 xFIP and .223 BABIP, which could indicate he's due for some regression. Kopech continues to rely heavily on his fastball and slider and may not be able to take that next step until he's able to mix in an effective third pitch more often, which has eluded him to this point.

Strikes out nine Sunday
Kopech allowed two runs on three hits and a walk while striking out nine over seven innings in a no-decision versus the Tigers on Sunday.
ANALYSIS
After a bumpy 10-strikeout effort versus the Angels on Monday, Kopech was back on track with a strong start. He limited the damage to a Spencer Torkelson two-run home run in the fourth inning. This was the third time in his last four starts that Kopech went at least seven innings, and he's had at least nine strikeouts in all of those efforts. For the season, he's at a 4.33 ERA, 1.18 WHIP and 79:32 K:BB through 68.2 innings. The right-hander's 4.2 BB/9 is still concerning, but he's shown enough strikeout potential, especially recently, to garner fantasy interest. He's lined up to make his next start at home versus the Marlins.

Kopech was a giant unknown heading into the 2021 season. When last we saw him, he left his final start after his promotion from the minors with an injury in 2018 which required Tommy John surgery to fix. He missed the 2019 season rehabbing, and opted out of the 2020 season due to health concerns. He came into 2021 as a reliever, something he had never done as a professional, and absolutely flourished in the role from a real baseball perspective. His success did not exactly translate into much fantasy success outside of his strikeout total, but he quickly reminded us what his right arm is capable of doing when it is healthy. Now the question will be: can he transition back to the rotation? If so, what will it look like? An effective third pitch has thus far eluded him, and that challenge along with the jump in workload may just make him a risk you let others take.
