PITTSBURGH (AP) — Isiah Kiner-Falefa had three hits, including a go-ahead single in the fifth inning, as the Pittsburgh Pirates avoided a three-game sweep with a 4-3 win over the Kansas City Royals on Sunday. Billy Cook lined a single to left to start the fifth and scored from first on a hit and run when Kiner-Falefa shot one to center to put the Pirates ahead 3-2. Carmen Mlodzinski pitched a perfect fifth inning in relief of Pirates starter Jared Jones, who allowed two runs in four innings. Brady Singer gave up four runs on six hits in five innings for Kansas City, which is four games back of first-place Cleveland in the AL Central.
