PHILADELPHIA — Ruben Amaro Jr. breathed a bit a easier when it came time to pick the Phillies’ 2013 opening day roster.

In 2012, the general manager struggled to find replacements for second baseman Chase Utley and first baseman Ryan Howard, both of whom were injured.

The Phillies finalized their opening day roster Saturday. Philadelphia will open its season at 7:10 p.m. Monday against the Braves in Atlanta.

“It was less stressful,” Amaro said. “It’s nice to have your three- and four-hole hitters.”

The Phillies will carry 12 pitchers, two catchers, five outfielders and six infielders. Fifteen players on this year’s opening day roster were not on it in 2012.

“That’s a lot of changeover,” Amaro said. “It’s a concern when you have this many changes. Are these guys going to jell? Bur our core players will help us to do that by their presence and the way they go about their business.”

Ender Inciarte, 22, made the team as the fifth outfielder. The Phillies selected Inciarte from the Arizona Diamondbacks in the Rule 5 draft. The Rule 5 draft is for long-time minor-leaguers who are not on a team’s 40-man roster. If the Phillies did not keep Inciarte on the active roster, they would have had to return him to the Diamondbacks.

Inciarte batted .273 this spring but is known for his speed and defense.

“He has instinct in the outfield that in my mind is a little like (Freddy) Galvis in the infield,” Amaro said of Inciarte. “He’s an aggressive player. I think he’s going to be a plus for us because defense in the outfield is a concern.”

The Phillies also chose to keep reliever Phillippe Aumont and send Mike Stutes to the minor leagues. Stutes pitched well in 2011 but appeared in just six games in 2012 because he underwent shoulder surgery last June.

“We don’t forget what Stutes did in 2011,” Amaro said. “He just needs to get back and get his reps in. We just think Aumont has a better chance to get people out now.”

A 162-game season is a long one, and the roster won’t be stagnant. Players are bound to be injured and come and go.

“It has a lot to change a lot,” Amaro said. “It will change.”
