Slater recorded a stolen base as a pinch runner in Sunday's 4-2 win over the Red Sox.
Slater has gone 6-for-15 with two doubles, one RBI and two runs scored over nine contests with the Orioles, but his theft Sunday was his first with his new team. He's had limited chance to make an impact as a short-side platoon player, and it's unlikely he serves as anything more than a fourth or fifth outfielder. For the year, he has a .211/.331/.260 slash line with one home run, three steals, 13 RBI and 16 runs scored over 151 plate appearances between the Giants, Reds and Orioles.
