Doug Fister delivered four scoreless innings in his minor league rehab debut Sunday afternoon with High-A Potomac and Nationals manager Matt Williams acknowledged to reporters Tuesday night that the right-hander is on track to join Washington’s starting rotation after just one more rehab outing.
That sets up Fister’s debut in a Nationals uniform, according to beat writer Adam Kilgore of the Washington Post, for May 7 against the Dodgers.
Fister was bothered this spring by right elbow inflammation and then suffered a lat strain a week before Opening Day. The Nationals acquired him via trade this offseason from the Tigers after he posted an impressive 3.67 ERA and 157 strikeouts across 208 2/3 innings in 2013 for Detroit.
Taylor Jordan has already been optioned to Triple-A by the Nationals to open a rotation spot.
A day after throwing an immaculate inning — getting through an inning on three consecutive strikeouts with nine pitches — against the Mariners, Dodgers reliever Zac Rosscup was placed on the 10-day disabled list with a left calf strain. The move made room on the 25-man roster for Kenley Jansen, who is back after missing some time due to an irregular heartbeat.
Rosscup pitched the ninth inning of Sunday’s 12-1 win over the Mariners. He struck out Kyle Seager, Ryon Healy, and Cameron Maybin on three pitches each. Rosscup is the fourth pitcher to throw an immaculate inning this season, joining Kevin Gausman, Max Scherzer, and German Marquez. 2018’s four immaculate innings is still far behind 2017’s record of eight.
Rosscup has pitched only 6 2/3 innings in the majors this year. He has yielded five runs (all earned) on seven hits and a walk with 10 strikeouts. He missed a significant amount of time earlier this season due to a blister on his left middle finger.
