"Fragile: please handle with care."

It's usually plastered on the outside of packages, warning others of the delicate contents that lie within its walls. One wrong move, though, and everything inside can shatter, thus becoming relatively useless.

Baseball pitchers tend to work the same way.

The finickiest of sorts — disrupt their routine, alter their habits or shift them back-and-forth unexpectedly, and often you'll quickly turn a 95 MPH fastball-chucking flamethrower into a mentally-derailed player that's simply nothing but damaged goods.

This is what makes what the Tennessee pitching staff is doing this season extremely special.

It's already more than a quarter of the way through the regular season, and many hurlers have already flip-flopped between different roles more than once. Some have transformed into starters, others now lock down the bullpen. One does just about everything.

And for the most part, no matter which guy in which inning on which night has trotted out to the mound for head coach Dave Serrano, it's churned out success.

Take Tuesday night in Murfreesboro for example.

On the road for the fourth consecutive game, six UT pitchers tossed a complete-game shutout en route to a 2-0 victory over the Blue Raiders.

Seems normal enough. Coming into the in-state battle, the Vols had won 14-of-15 while MTSU donned a lackluster 5-9 record.

Making up half of UT's dominant mound performance were sophomores Drake Owenby, Andrew Lee and Andy Cox, who allowed just a pair of hits and struck out six in four innings combined.

Again not surprising. A member of this trio has taken the hill in all but one of UT's 15 victories this season.

Just hardly ever in the roles they did Tuesday night.

It was Owenby who started for the first time in nearly a year; Lee who delivered the late-inning relief in what was his bullpen debut; and Cox who effectively converted the save, just the third of his career.

Now, rewind to three days earlier. In the pivotal second game of a treacherous road series at Arizona State, Lee got the ball first, Cox provided his services in the eighth and Owenby was the one called upon for the final three outs.

Every member of this threesome gave up at least one run against Sun Devils as the Vols hung on for dear life for a one-run win. Just 72 hours later, all three were appearing in different roles.

And all three delivered shutout performances.

Moving a starting to the bullpen can be extremely detrimental. Taking a closer out of his natural late-game spot can spell disaster. Tossing someone into the fire of a close game in the ninth can end in demoralizing fashion.

But that versatility hasn't just appeared out of nowhere for Serrano. It's been a mainstay since opening day.

Nick Williams? The senior began the season in the bullpen. That lasted all of one game, and now he's morphed into a Friday night godsend, owning a 2.33 ERA and two wins in three opening-weekend starts.

And what about Cox? The lefty has started midweek games and produced in long-relief. He appears to be the Vols' newly-anointed closer and boasts a measly 0.72 ERA.

"Andy has served many roles," Serrano said. "Starter, first out of the bullpen, middle of the game, late innings, closer. "We're going to ride that."

When trying to balance the individual mindsets of a pitching staff that's constantly shuffling, that ride can be a wild one, trying to ensure nothing falls apart along the way.

In Knoxville, though, everything is still intact.
