Mac Williamson SF GiantsContinuing the theme of celebrating former Valley League players who have been named a top prospect by John Sickels, today we have big Mac Williamson (Harrisonburg 2011), who Sickels named the 7th best prospect in the Giants’ system.

This is what John has to say about Mac:

Grade B-: Age 24, destroyed Cal League (.318/.420/.506) in 23 games but injured right before he was expected to be promoted to Double-A and had to have Tommy John surgery. Older prospect now but has always hit and had made good adjustments with his strike zone judgment before getting hurt.

“Has always hit” is apt for Mac. Over his career, he’s hit 300/380/519 in 841 plate appearances in the minor leagues. Here’s to better health in 2015!
