Koss started at second base and went 0-for-3 in Sunday's 6-2 loss to the Orioles. While he got the starting nod in place of Luis Arraez (wrist), Koss failed to make a positive impact at the plate. The 28-year-old infielder has gone hitless in both of his starts this season and has recorded one hit -- a double -- across seven plate appearances. Koss could continue starting for as long as Arraez is out, though manager Tony Vitello said he is targeting Tuesday's game in Cincinnati for Arraez's return, according to Susan Slusser of the San Francisco Chronicle.

Christian Koss: Breaking News
Multi-hit effort in spring loss
Koss went 2-for-3 with a run scored in Saturday's 8-7 Cactus League loss to the Diamondbacks. Koss singled in the fourth inning and came around to score before adding another single in the sixth. He's gotten on base frequently through 13 Cactus League appearances, slashing .423/.545/.423 with six runs scored, six RBI and a stolen base across 33 plate appearances during that span. The 28-year-old appears likely to earn a spot on the Opening Day roster in a utility role after making his big-league debut with the Giants last season, though Tyler Fitzgerald remains in the mix.
Doubles in victory
Koss started at second and went 2-for-4 with a double and a run scored in Sunday's 3-1 win over the Dodgers. Koss singled in the eighth inning before coming around to score the game-tying run. He also added a double in the ninth, marking his second multi-hit performance over nine appearances this month. Overall, he's slashing .267/.305/.376 with 22 RBI, 22 runs scored, nine doubles, three long balls and three stolen bases across 180 plate appearances in 72 games this season.
