Yu Darvish

Arthroscopic elbow surgery limited Darvish to eight starts in 2018. Adding insult to injury, he wasn't even good (4.95 ERA) in his brief time on the mound. He looked just as bad for most of 2019. The righty has relinquished a 4.36 ERA and 23 homers in 23 starts. Yet he has resoundingly reversed terrible early-season command with just seven walks in his past 10 outings. Also lost in his early troubles, the oft-injured righty has stayed healthy. He's the ultimate boom-or-bust starter whose diminished value is rapidly rising back to the SP3/4 drafters anticipated.

Darvish was so awful to start the season but after the break, he said he was feeling 110% and since then he has been dominant. There is a chance he'll continue the recent success and carry your rotation the rest of the season, but it is by no means the most likely scenario.

Darvish missed most of the 2018 season due to elbow and triceps injuries, and he was clearly not himself for the 40 innings he was able to pitch. Health has been a constant concern for Darvish, but he's been a consistently dominant strikeout pitcher, and last year was the first time in his Major League career that he's had an ERA over 3.90 or WHIP above 1.28. His team context in Chicago remains great, so the chance of a big bounce back season is there if he can just stay off of the IL.
