San Diego Padres superstar pitcher Yu Darvish was scratched from this start Tuesday night against the Pittsburgh Pirates due to an illness. While the specifics of the illness have not been expanded upon, Kevin Acee of the San Diego Union-Tribune reported that he will miss his start on Tuesday night, with Reiss Knehr taking the ball instead. While the team has not expanded upon Yu Darvish's illness, it seems possible that he will return to the pitching rotation for his next start. As of now, he is tentatively scheduled to start against the red-hot Cincinnati Reds on July 2nd. However, any lengthy time away from the team will likely put that start at risk.

At 37-41, San Diego needs to win every game possible, particularly against a team such as the Pittsburgh Pirates, who have lost nine of their last 10 games. Much like most of the San Diego Padres roster this season, Darvish has underperformed his expected numbers entering the 2023 campaign. Through 80.0 innings so far this year, the Japanese superstar has posted a 5-6 record with a 4.84 ERA with 85 strikeouts and a 1.225 WHIP.

Yu is pretty subdued, but even he was a little ticked about this call" - @SloanPivaHere's a closer look at Reiss Knehr, who will replace Yu Darvish on Tuesday night Heading into Tuesday's matchup with the Pittsburgh Pirates, the last-minute scratch obviously left San Diego Padres manager Bob Melvin in a bind, turning to Reiss Knehr in Darvish's place. The 26-year-old from Manhasset, New York has seen limited action in the MLB this season appearing in only 3.2 innings with the Friars, all of which have been out of the bullpen. Throughout those 3.2 innings, Knehr has struggled, posting a 12.27 ERA with three strikeouts.
