CINCINNATI -- Aroldis Chapman's seventh start for Triple-A Louisville against Rochester was a short night.
Chapman was roughed up for eight runs on nine hits and three walks over only 3 1/3 innings while striking out five. His undoing was six runs allowed during an eight-run Rochester top of the fourth inning.
Following Trevor Plouffe's three-run home run with one out in the fourth, Chapman left the game with the Bats trailing, 8-2. Of the 75 pitches he threw, 42 were strikes.
The outing sent Chapman's ERA from 2.84 to 4.63. Overall, he has allowed 18 earned runs, 36 hits and 21 walks while notching 41 strikeouts over 35 1/3 innings. In three May starts, the 22-year-old Cuban lefty has a 9.42 ERA.
