MLB.com’s Carrie Muskat reports that starter Jake Arrieta will need at least one more rehab start with Double-A Tennessee before rejoining the Cubs’ rotation. Arrieta showed up to spring training with a sore shoulder and has been behind schedule ever since.
Arrieta has made two rehab starts to date. On April 5, he allowed an unearned run in three innings of work. On Thursday, he tossed 3 2/3 innings of shutout baseball, striking out four and walking two.
Muskat said Cubs manager Rick Renteria received positive reports on Arrieta’s Thursday start. Once Arrieta is healthy enough to rejoin the rotation, he’ll displace Carlos Villanueva.
