Bob Nightengale of USA Today reports that the Cardinals will skip right-hander Carlos Martinez on Tuesday against the Nationals and call up left-hander Marco Gonzales to start instead.
According to Derrick Goold of the St. Louis Post-Dispatch, Martinez is dealing with a back issue which isn’t believed to be serious. The 23-year-old has already thrown a career-high 154 2/3 innings this season while posting a 2.91 ERA, but the results have been mixed over the past month. The Cardinals have their eyes on the postseason, so it makes sense to rest him now. Surely the Nationals won’t complain.
Gonzales, the Cardinals’ first-round pick from 2013, has thrown just 75 1/3 innings in the minors this season due to pectoral and shoulder injuries. The numbers on the whole haven’t been pretty for the southpaw, but he has a 2.66 ERA over his last four starts in Triple-A and will try to keep that going against major league hitters. The 23-year-old had a 4.15 ERA in five starts and five relief appearances in his first taste of the majors last year.
