White Sox's Reynaldo Lopez: May have been tipping pitches

Lopez believes he may have been tipping his pitches during his appearance Thursday, James Fegan of The Athletic reports.

Lopez was hit hard throughout his appearance, surrendering four extra-base hits in his three innings of work. He allowed a total of five earned runs, three of which came on back-to-back homers in the third frame. Lopez, who's competing for the final rotation spot with Carlos Rodon, pitched two perfect innings in his previous outing.
