Cardinals manager Mike Matheny is unsure of pitcher Carlos Martinez's role, according to the St. Louis Post-Dispatch.
Martinez was called up Friday, but hasn't been used yet. While Martinez has scheduled to start in the minors Friday, he might be used as a reliever in the majors. Matheny suggested Martinez could be a late-inning option. "I see him being able to be used in short stints too, especially as we’re close to having more arms around here," Matheny said. Once that happens, Martinez should settle in as a late-inning option.
Martinez has a 6.19 ERA in 16 innings.
