McMahon isn't starting Friday against the Padres, Jeff Sanders of The San Diego Union-Tribune reports.
McMahon will get a day off after going 4-for-17 in Colorado's last series against the Giants. He's assumed a larger role at second base ever since Brendan Rodgers went down with a hamstring injury, allowing Elehuris Montero to receive more action at third base. While McMahon sits, Alan Trejo will start at second base, batting seventh.
