The 26-year-old Peguero offers tremendous left-handed power but struggles against left-handed pitching and has long had a serious problem with strikeouts. He batted .260/.321/.460 in 505 Triple-A plate appearances last season and boasts a career .230 ISO (slugging minus batting average) in the minor leagues. However, Peguero has batted just .195/.242/.380 in the Majors.
Baseball America ranked him among Seattle's Top 30 prospect four times, twice placing him as high as No. 11. In their most recent write-up, they noted Peguero's freakish athleticism and surprising speed for a 6'5", 247-pound player, stating that he could be an average defender at a corner outfield spot. However, they also noted that he's likely a platoon player that will always post troubling strikeout numbers due to an inability to recognize breaking pitches.
