Manager Mike Matheny said Tuesday he liked Kozma's versatility. The shortstop has also played third, second, some outfield and even practiced catching this spring training. Though he's known more for his defense than his bat, Kozma began Tuesday with a .425 batting average.
Grichuk, acquired from the Los Angeles Angels, is hitting .262 with four home runs. He's played all three outfield positions.
''Just watching what he's done this spring, I couldn't imagine us leaving Florida without him on this club,'' Matheny said.
Stephen Piscotty will begin the season in the minor leagues.
