St. Louis Cardinals pitcher Chris Carpenter will likely begin the season on the disabled list due to shoulder/neck weakness.

According to MLB.com, Carpenter returned to St. Louis on Tuesday to undergo a new series of tests. The right-hander experienced renewed discomfort in his shoulder/neck during a session of catch on Monday.

He has yet to pitch in a spring training game this season.

Carpenter underwent a series of tests on Tuesday, which all came back negative. He will have more tests on Wednesday, with these focusing more on a potential nerve issue.

In 34 starts last season, Carpenter was 11-9 with a 3.45 ERA. He also went 4-0 with a 3.25 ERA in six playoff starts.
