Peterson went 1-for-3 with an RBI and a stolen base in Saturday's spring game versus Seattle.
Peterson is hitting just .217 this spring, but his OBP is nearly 100 points higher, and he owns a respectable .743 OPS over 27 appearances. Peterson will fill a super-utility role when the Brewers are at full strength, but with Luis Urias (quad) set to miss the start of the season, Peterson is on track to open the season on the favorable side of a third-base platoon with Mike Brosseau.
