Rangers outfielder Leonys Martin has a broken hamate bone, Stefan Stevenson of the Fort Worth Star-Telegram reports. The injury could require the bone to be removed surgically, which would likely end his season.
Martin, 27, hit a disappointing .220/.265/.314 with five home runs, 25 RBI, and 14 stolen bases in 309 plate appearances. The Rangers optioned him to Triple-A Round Rock last week and he was hitting better in nine games prior to the injury.
Delino DeShields, Jr. has been handling center field in Martin’s absence and figures to do so the rest of the way.
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.
