The Nationals were largely praised when they acquired right-hander Doug Fister from the Tigers during the offseason, but he has yet to throw a pitch for the club due to a lat strain suffered during spring training. If all goes according to plan, that will change soon.
Chase Hughes of CSNWashington.com reports that Fister threw 40 pitches in a bullpen session this afternoon and is scheduled to begin a minor league rehab assignment on Sunday, likely with High-A Potomac. The plan calls for him to throw about 60 pitches for his first outing before going five innings or 75 pitches five days later. That would set him up to join the Nationals around May 7.
Fister, 30, posted a 3.30 ERA from 2011-2013. Only six pitchers (min. 500 IP) bested his 123 ERA+ during that time.
Jesse Dougherty of the Washington Post reports that the Nationals will promote middle infield prospect Carter Kieboom to the majors ahead of Friday’s game against the Padres. The Nationals are currently dealing with injuries to shortstop Trea Turner and third baseman Anthony Rendon, so the club hopes Kieboom can help the team tread water at the very least.
Kieboom, 21, was selected by the Nationals in the first round (28th overall) in the 2016 draft. MLB Pipeline currently rates him No. 2 in the Nationals’ system and No. 37 overall. Kieboom has played both second base and shortstop this season after exclusively playing shortstop previously in his professional career.
With Triple-A Fresno to start the 2019 season, Kieboom hit .379/.506/.636 with three homers, 18 RBI, and 14 runs scored in 83 plate appearances.
