CHAPEL HILL, N.C. — North Carolina continued its mastery over Appalachian State University baseball with a 9-0 win over the Mountaineers on Tuesday night at Boshamer Stadium.

The defeat was Appalachian State's 15th-straight at the hands of North Carolina. The Mountaineers, who are 3-25 all-time against the Tar Heels, have not beaten UNC since an 11-10 victory at Boshamer Stadium in 1997.

North Carolina (15-9) jumped out to a 2-0 lead in the bottom of the first inning on Tuesday night and scored two more runs in the second, three in the fifth and two in the seventh en route to the victory.

Appalachian State (7-17) managed just three hits against five UNC pitchers, with only one coming after Brandon Burris led off the third inning with a bunt single.

The Mountaineers' best scoring opportunity came in the seventh when a leadoff single by Michael Pierson, a walk by Grayson Atwood and a groundout by Noah Holmes put two runners in scoring position with only one out. However, UNC reliever Hansen Butler got the Tar Heels out of the jam unscathed with a strikeout and a pop up.

The Mountaineers' three hits were a season low and the shutout was their second of the season (App State was blanked, 4-0, on March 11 at Georgia).

In addition to Burris and Pierson, Dillon Dobson also singled for the Mountaineers.

Skye Bolt led North Carolina by going 2-for-4 with a home run and three RBI.

Appalachian State gets another crack at Atlantic Coast Conference competition on Wednesday night when it hosts Wake Forest. First pitch is set for 5 p.m. at Appalachian's Beaver Field at Jim and Bettie Smith Stadium.
