Let’s check in on a few roster situations from the National League.
- The Nationals plan to give Carter Kieboom an opportunity to win the third base job, manager Dave Martinez told reporters (including Todd Dybas of NBC Sports Washington). The 22-year-old is a consensus top prospect coming off a year in which he hit .303/.409/.493 with 16 home runs in 494 plate appearances. Kieboom has played mostly in the middle infield in the minors, but Martinez indicated he’ll be used strictly as a third baseman for the time being. Washington hadn’t previously had room for Kieboom at the hot corner, but the departure of Anthony Rendon and failure to reel in Josh Donaldson created an opening. If Kieboom doesn’t prove ready for everyday playing time on a contender, Asdrúbal Cabrera gives Martinez a fallback option. Starlin Castro is on hand, too, but it seems Washington will keep him at second base full-time, relays Sam Fortier of the Washington Post.
- Marlins’ outfield prospect Monte Harrison has an opportunity to win a spot on Miami’s season-opening roster, relays Joe Frisaro of MLB.com as part of a reader mailbag. Harrison, one of Miami’s top prospects, slashed a solid but unspectacular .274/.357/.451 in his first crack at Triple-A last season. Given the continued struggles of Lewis Brinson, who was acquired alongside Harrison in the regrettable Christian Yelich trade, there could be an opportunity for Harrison to claim the center field job. As Frisaro notes, Harrison is already on the Marlins’ 40-man roster, so no further move would be necessary.
- Mike Yastrzemski seems likely to get the first crack at the center field job for the Giants, relays Alex Pavlovic of NBC Sports Bay Area. That could give an opportunity for prospect Jaylin Davis, acquired last summer from the Twins, to stake a claim to a corner outfield spot. Yastrzemski was quite good for San Francisco in 2019, slashing .272/.334/.518 (121 wRC+) while serving primarily in the corner outfield, although he did start a pair of games in center. It’s an open question whether he can sustain that level of offensive production, considering he was previously an unheralded 28-year-old rookie. Steven Duggar’s also on hand and is a more natural fit in center defensively, but Pavlovic notes that he’s unlikely to have an everyday role. That’s not surprising, as Duggar owns a woeful .241/.286/.358 line (72 wRC+) over the past two seasons.
