Backup Catcher Chris Stewart will receive a second opinion on his injured right knee and is likely to undergo surgery later this week, the club announced on Monday. Stewart injured the knee on March 12 during the game against the Twins in Fort Myers, Fla. In a statement the club said that Stewart has continued to experience symptoms and has been held out of the lineup per the club doctor’s recommendation. Pittsburgh will have more information following Stewart’s visit with Dr. James Andrews this week. Stewart was 0-13 in spring training. Tony Sanchez will make the team out of spring training, barring a trade. Source: Pirates.com
