The Rockies plan to pick up Anderson's $12 million option for 2015 or sign him to a longer deal, according to Rosenthal.
The 26-year-old was traded to the Rockies from the Oakland Athletics back in December. He broke a finger on his pitching hand in April, returning to the rotation July 13. In his last two starts combined, he has given up six hits and one run in 13.1 innings, lowering his season ERA to 3.24. In 33.1 innings, Anderson has only surrendered one home run.
The Rockies are in last place in the NL West with a 43-63 record.
