In turn, they have optioned Wilmer Flores to Triple-A to make room for Lagares on the roster.
Flores had been hitting just .238 with a .256 OBP in 82 sporadic at bats since joining the team in early May.
Lagares has played in 42 games this year and had been on the DL twice, most recently for a right intercostal injury.
He's batting .295 with 15 extra base hits and 18 RBI in 42 games with the Mets this year.
Flores just wasn't playing enough - and, when he was playing consecutive days, he wasn't hitting enough. Ruben Tejada may not be a better hitter, but he at least has been drawing walks, working counts and getting on base. So, if Tejada is Terry's choice, Flores had to go to Triple-A to get regular at bats. At 22-years-old, and with his potential, it made no sense to have him sitting the bench.
In regards to the roster, this now means the Mets have six outfielders and no back-up shortstop, which a) is very confusing, and b) gives credence to Adam Rubin's report that Chris Young was in jeopardy of being cut. The guy has three home runs in two days, so I'm sure that complicated what was probably already a difficult decision.
