Shane Peterson (OF)
Profile: With the Brewers down to just three outfielders on their active roster, 27-year-old Shane Peterson was promoted to Milwaukee on Wednesday to join the team in St. Louis. Peterson was originally drafted by the Cardinals in the second round of the 2008 draft, but was traded to Oakland a season later, along with pitcher Clayton Mortensen and first baseman Brett Wallace in a deal that sent All-Star outfielder Matt Holliday to St. Louis.
After quickly advancing to Double-A with the Cardinals, Peterson joined the A’s Double-A team in Midland following the 2009 trade. He spent parts of four seasons at Midland before advancing full-time to Triple-A Sacramento in 2013. In 126 Pacific Coast League games that season, Peterson hit .251 with 12 home runs and knocked in 79. He returned to Sacramento in 2014 and played in 137 games, hitting .308 with 11 home runs and 90 runs batted in.
Peterson was placed on waivers by Oakland following the 2014 season and claimed by the Chicago Cubs, but the Cubs put Peterson back on waivers a few days later and Milwaukee swooped in and claimed him. He joined the Brewers in big league camp for most of spring training, hitting .296 in 17 games, before being sent to Triple-A Colorado Springs. In 47 games with the Sky Sox, Peterson hit .320 with seven home runs and 27 runs batted in.
Strengths: Peterson has experience at all three outfield positions, as well as first base, splitting most of his time this season with Colorado Springs between right and left field. The former Long Beach State product has hit for decent average throughout his minor league career and has improved his power numbers the last few years as well, racking up 56 extra-base hits in 2014.
Weaknesses: Peterson’s strikeout numbers are a bit on the high side as he’s averaged roughly a strikeout per game since reaching Triple-A and has nearly twice as many punchouts as walks throughout his minor league career. Though he has played centerfield in the past, that’s probably not Peterson’s strongest position. He has average speed but has not stolen a base this season, getting gunned down on his lone attempt.
Future: Best case scenario for Peterson is probably as a fourth or fifth outfielder. He profiles more as a corner outfielder and could see some action in left field until Khris Davis returns but don’t expect to see Peterson getting regular playing time unless Milwaukee is hit even harder by the injury bug. He’s understandably had more success against right-handed pitchers than lefties over the past few seasons and provides the Brewers with another left-handed hitting option off the bench. He could stick around if/when the Brewers decide to move Parra but doesn’t profile as a starter long-term.
