ST. LOUIS (AP) - The St. Louis Cardinals say an MRI exam on right-hander Michael Wacha's injured shoulder showed progress, but not enough for him to resume throwing.

General manager John Mozeliak said Monday that Wacha, the NL championship series MVP last fall, will be evaluated again in two weeks. He said continued treatment along with weight training to strengthen the area around the stress fracture was in the pitcher's best interests.

Wacha has been on the 15-day disabled list since June 18. He's 5-5 with a 2.79 ERA for the defending National League champions.

Mozeliak said Joe Kelly, on the DL since April 17 with a left hamstring strain, could return to the rotation Friday at Milwaukee.
