The Miami Marlins placed rookie right-hander Jordan Yamamoto on the 10-day injured list Wednesday with a forearm strain four days after he was roughed up in a start against the Philadelphia Phillies.
Yamamoto, 23, matched a season high by giving up six earned runs against the Phillies on Saturday in a 9-3 defeat. His 3 2/3 innings pitched were a season low. Yamamoto is 4-5 this season over 13 starts with a 4.87 ERA.
He was replaced on the active roster by right-hander Robert Dugger, who was recalled from Triple-A New Orleans. Dugger is expected to start for the Marlins on Thursday at home against the Cincinnati Reds.
Dugger, 24, has just one previous major league appearance, a start against the New York Mets on Aug. 5 when he gave up six earned runs on five hits and four walks in five innings of a 6-2 Miami defeat. He is a combined 8-10 with a 5.15 ERA over 23 starts on the Double-A and Triple-A levels this season.
