Watching Andrew Cashner slice through the Arizona Diamondbacks lineup, it was hard to remember why there were ever any questions about his place in the rotation.

The debate has rattled around the entire organization starter or reliever? from the moment the Cubs made him the 19th overall pick in the 2008 draft.

Cashner lived up to the hype on Tuesday afternoon in his first career major-league start before giving Cubs fans everywhere moments of concern.

The 24-year-old walked off the mound at Wrigley Field in the sixth inning with what the Cubs described as tightness in his right shoulder.

After Cashner threw his 72nd and final pitch which was clocked at 92 mph into the dirt to walk Willie Bloomquist, he appeared to bite his glove.

There was no one warming up in the bullpen as athletic trainer Mark ONeal, pitching coach Mark Riggins and manager Mike Quade converged on the mound. Cashner was to be examined by the Cubs staff.

The uncertainty overshadowed a sharp outing from Cashner, who gave up only one run on two hits in 5.1 innings.
