The Chicago Cubs have pushed Tyler Chatwood’s next start to Monday at the earliest after the right-hander experienced tightness in his back, per Tim Stebbins of NBC Sports. Colin Rea will trot in from the bullpen to start on Saturday in his stead (technically, Alec Mills started for Chatwood on Friday, and Rea will start in Mills’ place). Chatwood has continued his streaky tenure this season in Chicago, though the good has outweighed the bad through three starts. The 30-year-old Chatwood put the Northside aflutter with a pair of quality starts in which he yielded 12 2/3 innings, two wins, 19 strikeouts, and just a single earned run. He gave it all back with 8 earned runs in just 2 1/3 innings in his third start against the Royals. The Cubs have a twin bill with the Cardinals scheduled for Monday.
- Bad news could be on the horizon for the San Diego Padres. Closer Kirby Yates has been scheduled for an MRI to investigate recent elbow discomfort, per Kevin Acee of the San Diego Union-Tribune. The late-blooming Yates has developed into arguably the game’s best closer over the past two seasons. He’s not been himself through 5 appearances this year. He’s currently rocking a cumbersome 10.38 ERA/5.62 FIP with 7 hits and 4 walks to 7 strikeouts over 4 1/3 innings. He does have 2 saves and a hold. An injury would certainly be a blow to a San Diego bullpen already down Andres Muñoz and Trey Wingenter. Even so, the Friars are flush with potential replacements: Emilio Pagan and Drew Pomeranz are likely next in line to secure W’s in San Diego.
- Yoshihisa Hirano is finally on his way back to the diamond after testing positive for COVID-19 early in training camp, per MLB.com’s Greg Johns (via Twitter). After some tune-ups at the alternate site, Hirano could find himself in the Seattle Mariners’ bullpen shortly. Hirano, 36, joined the Mariners this offseason after two years with the Arizona Diamondbacks. He proved himself a reliable arm in the Dbacks’ pen. He owns a 3.47 ERA/3.85 FIP in the states after a successful career in Japan.
