Murakami (hamstring) will report to Triple-A Charlotte on Monday to begin a minor-league rehab assignment, Tom Withers of the Associated Press reports.
Murakami suffered a Grade 2 right hamstring strain in late May and landed on the 10-day injured list. The star rookie will likely need a couple of games in the minors to get his timing back at the plate, but he appears on track to rejoin the big-league squad before the All-Star break. Jacob Gonzalez has been hitting well over the past few weeks as Chicago's primary first baseman, but he'll likely lose out on playing time when Murakami is activated.
