On Wednesday night, Marlins right-hander Henderson Alvarez had his start against the Nationals (GameTracker) cut short because of elbow stiffness. He pitched five scoreless innings before being lifted. The Marlins are calling it a precautionary move, but obviously the situation bears monitoring.
This season, Alvarez has pitched to a 2.97 ERA after 11 starts. For his career, the 24-year-old owns an ERA of 4.10 (99 ERA+) and a K/BB ratio of 2.04 across parts of four big-league seasons.
Alvarez missed roughly half the 2013 season because of shoulder inflammation and also experienced some minor elbow soreness in 2012.
