Modest about his defensive ability at second base, Murphy deflected praise to his fellow middle infielder.
"I think that showed how good Ruben Tejada is at shortstop," Murphy said. "He did all the work on that one. I got the feed and had enough time."
Whether you credit Tejada, Murphy or both, the play ultimately kept the Brewers off the scoreboard in the eighth inning after having two on and none out.
But the quick turn to get Lucroy at first base was the type of play that Murphy, who is in his first full season as a second baseman, may not have made a few months ago.
"Probably not," said Mets manager Terry Collins. "He's practiced and practiced and practiced. He's been so good around the bag. That's been the most impressive thing. We all know his hands are OK, but the footwork around the bag is something that, it just takes a while to get it. And he works at it so hard. He's done a good job."
Murphy's 15 errors ranks as the second most among National League second basemen, but his defense has been as good or better than the Mets could have expected.
The toughest plays for Murphy have been around the bag, whether covering second on stolen-base attempts or turning the double play. But he has made noticeable progress.
Murphy credits infield coach Tim Teufel, as well as fellow middle infielders Justin Turner and Tejada, for "really going out of their way" to help him with the transition.
"I'm excited about the strides I've made," Murphy said. "But I also understand there's still a lot of work I've got to do.
"Just making sure that I have my footwork right and making sure that I get to the bag on time. [That I get] in a position to protect myself, but also in a position to reward our catchers for a great throw."
