Weathers is listed as the Marlins' probable starting pitcher for Monday's game against the Padres, Jeff Sanders of The San Diego Union-Tribune reports.
Weathers was optioned to Triple-A Jacksonville in early August after making his Marlins debut as a reliever, giving up six runs on six hits and four walks while striking out five in 3.2 innings against the Rangers. However, he looks likely to rejoin the major-league club Monday to serve as the starting pitcher against his former team. Whether he makes any starts beyond Monday will likely depend on how he fares against the Friars.
