Wells will be pushed back in camp due to a sore oblique, Roch Kubatko of MASNSports.com reports.
The 24-year-old dealt with a similar issue early in spring training last season before being reassigned to minor-league camp. Wells was added to the 40-man roster in November and last pitched in 2019 with a 2.95 ERA, 1.07 WHIP and 105:24 K:BB over 137.1 innings (24 starts).
