"We finally woke up," Flores said after the Mets' 14-1 rout of the Brewers, which included Flores' slam in the Mets' 10-run fourth at Citi Field.
The slam did not quiet the debate about Flores playing shortstop, where he's made nine errors this season.
But Terry Collins still has confidence in Flores' bat. His team-leading sixth homer of the season tied a career high.
"(The grand slam has) got to help him," Collins said of Flores, who is hitting .250 with 15 RBI. "He's going to put up big offensive numbers. With the defensive side, I think he's really been pressing at the plate a little bit."
Flores said he wasn't offended to be hitting ninth. "It didn't bother me, it didn't affect me, either," he said. "Every time you hit a home run, it's a good feeling."
No. 8 hitter Jacob DeGrom was 3-for-3, with an RBI single in the second and two singles in the fourth. According to STATS Inc., he became only the second pitcher since at least 1914 to have three hits batting eighth, following St. Louis' Adam Wainwright vs. Atlanta on Aug. 22, 2008.
"That was fun," deGrom said. "Just trying to get up there and hit the ball hard, and they found holes."
