The victory pushed UT's winning streak to seven and improved the Big Orange to 15-2 at its home park in 2011.

In the circle Lady Vol sophomore starter Ivy Renfroe was terrific, tying her career-high with 11 strikeouts while tossing a three-hit, complete-game shutout to improve to 12-3.

Sophomore right fielder Kat Dotson helped guide Tennessee's 10-hit offensive attack by going 2-for-3 with a double, a triple and three RBIs. Senior center fielder Kelly GrieveĀ  went 3-for-4 performance with a double, an RBI and a pair of steals to give her 19 thefts on the season. Junior catcher Shelby Burchell was just 1-for-3 but made that one hit count by blasting her team-leading 12th home run to begin the bottom of the second. Sophomore designated player Whitney Hammond was perfect at the plate, going 2-for-2 with a pair of runs scored.

After Appalachian State left a pair on base in the top of the second, Burchell broke the scoreless dead-lock in the bottom half by blasting her team-best 12th home run of the season.

The solo big fly also marked UT's 49th as a team, moving the squad within three home runs of the single-season school record of 52 set back in 1996 and equaled in 2002 and 2005.

Renfroe settled in after a swinging bunt got second baseman Megan Rembielak on with one out in the ASU third. Renfroe, a Jackson, Tenn., native struck out five consecutive Mountaineers over three innings and struck out the side in the fourth, retiring seven consecutive batters.

The Big Orange blew the contest open in the bottom of the fourth by scoring four runs on three hits while getting some help from Appalachian State. A fielding error on a Burchell bouncer started the inning off on the wrong foot for the Mountaineers. Freshman pinch runner Tory Lewis swiped second and advanced to third on an infield single by rookie first baseman Melissa Davin. An air-mailed throw to center by ASU catcher Michelle Lighton on a Davin stolen base attempt allowed Lewis to cross with UT's second run. A failed pick-off throw with Davin at third made it 3-0. After a walk by Hammond, Grieve and Dotson delivered consecutive RBI doubles to expand the advantage to 5-0.

A two-out walk issued by Renfroe to third baseman Katie Boyd broke Renfroe's streak of seven consecutive retired in the top of the fifth. She was in firm control, however, concluding the frame by catching Rembielak looking at strike three for one of Renfroe's seven strikeouts looking.

Big Orange junior shortstop sub Ashley Andrews reached on a fielding error to christen the bottom of the sixth. Hammond stepped to the dish and singled on the infield as ASU eventually rushed the play and threw the ball away, marking the Mountaineers' fifth miscue of the evening. With Lady Vols occupying second and third and two retired, Dotson drilled a triple into the corner to plate both runners and finalize UT's offensive output at seven tallies.

From there Renfroe raced through the Appalachian State line-up in order in the top of the seventh to secure Tennessee's 35th victory of the season.
