"Cardinals' Sonny Gray Faces Opening Day Uncertainty Due to Hamstring Strain"
St. Louis Cardinals' projected ace Sonny Gray suffered a mild hamstring strain, putting his status for Opening Day in doubt. The 34-year-old right-hander, who signed a three-year, $75 million contract in November, left Monday's exhibition start with tightness in his hamstring and underwent an MRI that revealed the minor strain. The Cardinals are uncertain about Gray's timeline for return, potentially impacting their rotation plans for the upcoming season.
