ATLANTA -- The Atlanta Braves made a couple of surprising roster moves for the NL Division Series, adding hard-throwing reliever Daysbel Hernandez and top prospect AJ Smith-Shawver ahead of Game 1 Saturday against the Philadelphia Phillies.

The Braves decided not to use Kyle Wright, a 21-game winner a year ago who was slowed by injuries this season. They also passed on 40-year-old reliever Jesse Chavez, who missed a good chunk of the season with a leg injury but posted a 1.56 ERA in 36 appearances.

Philadelphia made only one change from the 26-man roster it used for a two-game sweep of the Miami Marlins in the wild-card round. Right-hander Michael Lorenzen (9-9, 4.18 ERA) replaced infielder Weston Wilson to give the Phillies a 13th pitcher.

The addition of Hernández was the biggest shocker for the Braves. The 27-year-old Cuban reliever has made only four big league appearances, allowing three runs on six hits and three walks in 3 innings.

But he was highly effective on a rapid rise through the minor leagues this season, posting a cumulative 2.19 ERA in 23 appearances with High-A Rome, Double-A Mississippi and Triple-A Gwinnett. Most notably, he had 36 strikeouts in 2 innings.

Smith-Shawver is another fast climber, going from Class A to the big leagues in just his third professional season. The 20-year-old right-hander appeared in six games with five starts for the Braves, going 1-0 with a 4.97 ERA.

The Braves went with 12 pitchers and added infielder Vaughn Grissom as an extra position player.

Grisson, 22, came into spring training as the front-runner to start at shortstop but wound up spending most of the season in Triple-A, where he batted .330 with eight homers and 61 RBIs.
