 Costa Kerstad, outside, one ball and one strike. Heston has certainly had a memorable homestand. He collected his first home run of the regular season, third in his career, and then last night was a career first. 1-1, fouled back, and it's one ball and two strikes. The first career grand slam for Heston Kerstad. And it was a doozy, prodigious power on display for Kerstad.
