MIAMI -- Twelve years later, Carlos Gomez is back in the New York Mets' lineup.

New York selected Gomez's contract from Triple-A Syracuse and had him batting sixth and in right field Friday night at Miami.

The Mets placed outfielder Michael Conforto on the seven-day injured list due to a concussion, and designated outfielder Keon Broxton for assignment. They recalled right-hander Paul Sewald from Syracuse.

Gomez, an All-Star for Milwaukee in 2013-14, last played for the Mets when he was a rookie in 2007. They signed the 33-year-old outfielder to a minor league contract in March, and he batted .270 with 22 RBIs in 35 games for Syracuse.

"He obviously has been swinging the ball really well," Mets manager Mickey Callaway said. "The defense has been outstanding, the leadership, the baserunning. From top to bottom the reports have been excellent. That's why he's up here getting a chance to help us win some games."

Broxton is batting.143 in 34 games. The Mets hope to keep him in their system.

"It just wasn't happening for him," Callaway said. "We have confidence this kid can play. We are very hopeful he is going to be back in the organization and help us at some point this year."

Conforto was hurt Thursday in Washington when he collided with a teammate while chasing a popup. On Friday he saw a neurologist, who prescribed no baseball activities for the next couple of days, and a re-evaluation is expected Monday.

The flurry of roster moves came with the Mets third in the NL East at 20-22.

"We have high expectations that we were very vocal about when the season started," general manager Brodie Van Wagenen said. "We have not lowered our expectations. We want to hold ourselves accountable to win games. We anticipate getting on a roll here and trying to make a run at this thing."
