Tigers score 3 in 8th to top Royals

Wilson Betemit capped a three-run eighth with 4, game series.

Ramon Santiago and Victor Martinez also knocked in one run apiece in the eighth for the Tigers, who lead the White Sox by 5 1/2 games in the AL Central.

Detroit starter Rick Porcello gave up four runs on eight hits over seven innings, while Daniel Schlereth (2-1) tossed a scoreless eighth to pick up the win.

Jose Valverde worked around a two-out single and walk in the ninth to pick up his 40th save of the season. He is the second pitcher in Tigers history to register 40 saves in a single season. Todd Jones established a Tigers single- season record with 42 saves during the 2000 season.

Eric Hosmer hit a pair of solo home runs to record his first career multi- homer game for the Royals, who have lost two in a row since a two-game winning streak.

Nate Adcock made a spot start in place of Felipe Paulino, who was scratched earlier on Wednesday because of back spasms. Adcock allowed two runs on six hits over 5 1/3 innings.
