PHOENIX (AP) — Cincinnati Reds All-Star second baseman Scooter Gennett injured his right leg while fielding a grounder against Milwaukee and was helped off the field.

Gennett ranged to his left for a ball off the bat of Yasmani Grandal leading off the second inning Friday. Gennett slid to make the stop and threw to pitcher Robert Stephenson covering first for the out. Gennett went to his knees and was helped off by Reds head athletic trainer Steve Baumann and manager David Bell.

“I don’t know exactly if it was when he fell or when he made the throw,” Bell said. “He felt something in his groin.

Cincinnati says Gennett was to have an MRI.

The 28-year-old Gennett reached the majors with the Brewers in 2013 and was claimed off waivers by his hometown Reds near the end of spring training two years ago. He made his first All-Star team last season, hitting .310 with 23 homers and 92 RBIs.

Top prospect Nick Senzel could be a candidate to replace Gennett. Senzel was reassigned to minor league camp earlier Friday.

Zach Davies pitched 5 1/3 innings for Milwaukee in a 6-4 win over the Reds. Davies found out Thursday he had a spot in the Brewers’ rotation.

ROYALS 15, GIANTS 3

Madison Bumgarner allowed seven runs and ten hits in two innings for San Francisco, a lousy outing that wasn’t helped when the Giants mustered just six hits.

Whit Merrifield and Adalberto Mondesi each had two hits, and Chris Owings, Hunter Dozier, Khalil Lee and Frank Schwindel each homered for Kansas City. Martin Maldonado added three hits, and Homer Bailey struck out seven over six innings of two-run ball.
