PORT ST. LUCIE, Fla. — It was Tim Tebow’s day, but another lefthanded-hitting Mets outfielder tried to steal the show on Wednesday.

Jay Bruce went 2-for-3 with a double and his first home run of spring training in the Mets’ 8-7 victory over the Red Sox at First Data Field. Bruce, whom the Mets have penciled in as their starting rightfielder after they were unable to trade him in the offseason, is batting .417.

“I feel comfortable,” Bruce said. “Plenty of work left to do. It’s early in spring, but progressing well. I try not to worry about the actual results of spring training games, but that my work is kind of in line with where I feel like it needs to be this time of year. It’s going well so far.”

Bruce, who struggled mightily after joining the Mets from the Reds at the trade deadline, still managed to hit a combined 33 home runs with 99 RBIs.

“That was some kind of game he played today,” said hitting coach Kevin Long. “That was the biggest take-away from today’s game — how he played.”
