Bumgarner underwent successful surgery Saturday to fix his fractured fifth metacarpal, Amy Gutierrez of NBC Sports Bay Area reports. On Friday, the news got even worse as the ace of the staff, Madison Bumgarner, was hit by a vicious line drive resulting in a fractured pitching hand.

Giants manager Bruce Bochy was relieved that the injury wasn't more serious. A more concrete timetable should emerge as he continues to progress in his recovery.

San Francisco Giants right-hander Jeff Samardzija will likely begin the season on the disabled list after being diagnosed with a strained pectoral muscle. But now, between Bumgarner's injury and Samardzija's, the Giants rotation is in disarray.

Kansas City second baseman Whit Merrifield led off the top of the third inning and hit a come-backer right to Bumgarner, who put both hands up in anticipation of the ball.

Bumgarner said about his missing action that it will be tough but he could handle it. Last season was the first time since he started 18 games in 2010 that he didn't have at least 31 starts for the season.

Bumgarner, the 2014 World Series MVP, missed almost three months last season with a shoulder injury after a dirt bike accident on April 20 during an off day in Colorado.

Bochy would not say if veteran Johnny Cueto would become the No. 1 starter and appear on Opening Day when the Giants visit defending NL champions the Los Angeles Dodgers next Thursday.
