Detroit Tigers starting pitcher Justin Verlander (35) throws against the Kansas City Royals during the first inning of a baseball game Monday, April 16, 2012 in Kansas City, Mo.
DETROIT (AP) _ Justin Verlander has left Detroit's game against Kansas City on Thursday with what the team described as cracked skin on his right thumb.
Verlander allowed one earned run in seven innings before departing. The right-hander is day-to-day.
Verlander allowed eight hits and didn't seem to be laboring too much when he left the mound in the seventh, but rookie Bruce Rondon came in from the bullpen the following inning, replacing Verlander and making his major league debut. Rondon allowed a run to tie the game at 3.
The 30-year-old Verlander has made at least 30 starts every season since 2006, when he was the American League Rookie of the Year.
