CHARLESTON, W.Va. -- The West Virginia Power pitchers were the ones doing the intimidating during Tuesday's doubleheader.
Nineteen-year-old Tyler Glasnow and Jhondaniel Medina set the tone in the opener, combining on a one-hit shutout as the Power blanked the Kannapolis Intimidators 1-0 in seven innings.
Then in the nightcap, 18-year-old Luis Heredia and Kyle Haynes worked on a three-hitter as West Virginia completed the sweep with a 5-1 victory over the Intimidators. A paid crowd of 1,979 attended the South Atlantic League matchup at Appalachian Power Park.
The Power (18-11), which has won six straight, vaulted a half game into first place of the Northern Division over the Hagerstown Suns (19-13).
West Virginia and Kannapolis (12-20) were rained out Monday, which forced the doubleheader on getaway day. Both games were seven-inning affairs.
The 6-foot-7, 213-pound Glasnow fired six shutout innings, surrendering one hit and two walks with six strikeouts to earn the win. The right-hander from California improved to 7-2 and lowered his earned run average to 2.27. Glasnow only allowed four balls to leave the infield.
"He's trying to figure out how to be great,'' said Power pitching coach Jeff Johnson. "He's still too young to know that yet. He's come a long way since the beginning [of the season]. I'm proud of that.''
Medina earned his third save in the final frame, setting down the Intimidators in order. He punctuated the effort by fanning Kannapolis' Kale Kiser, who got the lone hit off Glasnow on a broken-bat infield single in the fifth.
Heredia (2-2) allowed one earned run on three hits with two strikeouts and three walks. After winning his debut at home June 23, The 6-6, 243-pound Heredia posted a 0-2 mark in four starts on the road with a 6.31 ERA.
"Luis's doing what an 18- and 19-year-old is going to do,'' Johnson said. "He's really good at times and sometimes he's not. He battled through some things. The third inning was difficult for him and he got out of that without a lot of damage.''
