Four!

Keep your eye on Aaron Bates. The 23-year-old is a first baseman for the single-A Lancaster JetHawks, a Red Sox farm club in the California League, and he recently hit four home runs in one game, which apparently hasn't happened at any level of pro baseball since 1949.

According to an Internet scouting report, the North Carolina State graduate is “very strong 1B with high power potential. Hits a lot of home runs to the opposite field. Excellent plate discipline. Sold defensive first baseman, limited range. Also played catcher in college. Hard worker with a laid back attitude.”
