Mark Mulder may undergo an MRI to determine what is causing soreness in the front of his left shoulder. Mulder complained of the problem to Cardinals trainer Barry Weinberg after pitching just three innings on Sunday in which he left after giving up four runs. It was Mulder’s third ineffective start this month.
Weinberg said they wanted to determine if bad mechanics are leading to the soreness or if the soreness is leading to bad mechanics.
Mulder has given up 15 earned runs in 11 innings and hasn’t made it past the fourth inning in any of his three starts.
