ASHEVILLE, N.C. -- Jeff Kobernus drove in four runs with one swing of the bat.
But the Hagerstown Suns still let a whole busload of runners get away.
Hagerstown's second baseman hit his first home run of the year -- a grand slam -- on Wednesday but the Suns' inability to cash in on 15 runners who were stranded on base led to a 13-10 loss to the Asheville Tourists.
The Suns (46-50) squandered a 9-7 lead by allowing four runs in the seventh and two more in the eighth for another late-inning loss.
Asheville took an 11-10 lead in the seventh after Ben Graham (1-1) replaced Suns reliever Patrick Arnold with two runners on base. Nolan Arenado had an RBI single and Helder Velazquez followed with a two-run double to tie the score. The Tourist took the lead on Dallas Tarleton's RBI single.
