Carpenter (oblique) is on track to rejoin the Cardinals on Saturday in Milwaukee, Rob Rains of StLSportsPage.com reports.
Carpenter will play in one more rehab game with Triple-A Memphis on Friday before a likely return to the big club. Out since early April with a right oblique strain, Carpenter has gone 4-for-17 with two homers in his first five rehab contests. Upon his activation, Carpenter could see some starts at designated hitter versus righties for an offense that's desperately looking for a spark.
