CHICAGO (AP) — Edward Olivares and Nick Gonzales homered, and the Pittsburgh Pirates beat the Chicago Cubs 5-4 on Thursday night.

Olivares hit a two-run homer in the first inning. He also doubled and scored in the sixth against Justin Steele (0-1) to make it 5-3.

Gonzales hit a solo drive in the fourth, and Jared Jones (3-4) struck out seven in six solid innings. Colin Holderman gave up a sacrifice fly to Christopher Morel in the eighth, but the Pirates opened the four-game series on a winning note after losing six of eight. They dropped two of three to the Cubs in Pittsburgh over the weekend.

Jones was charged with three runs and seven hits. The 22-year-old right-hander has gone at least five innings and allowed three runs or fewer in each of his nine career starts. This was his fifth outing without a walk, and he never faced a three-ball count with his slider keeping the Cubs off balance.
