Randy Wolf won a spot in the Mariners’ starting rotation coming out of spring training, but then the team asked him to sign an advanced consent form that more or less reworked his contract terms and the 37-year-old left-hander requested his release.
Two weeks later Nick Piecoro of the Arizona Republic reports that Wolf is close to signing a minor-league contract with the Diamondbacks, who lost starter Patrick Corbin and reliever David Hernandez to Tommy John elbow surgery recently.
Wolf is himself coming back from Tommy John surgery, which knocked him out for all of last season. He wasn’t particularly effective this spring in Mariners camp and had a 5.65 ERA for the Orioles and Brewers in 2012, so it’s tough to expect much from Wolf at this point.
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.
