ARLINGTON, Texas -- The Arizona Diamondbacks added an extra bat for the World Series, putting Jace Peterson on the roster Friday and dropping pitcher Slade Cecconi for their matchup against the Texas Rangers.

The Rangers went with the same 26 players from their American League Championship Series victory over the defending champion Houston Astros.

Peterson, acquired from the Oakland Athletics on July 31, appeared in two games in the National League Division Series against the Los Angeles Dodgers. In his only plate appearance, he grounded out as a pinch hitter for Evan Longoria in the eighth inning of the 4-2 win over the Dodgers that completed a three-game sweep.

Peterson was a defensive replacement for Longoria at third base in the ninth inning of the opening 11-2 win.

The 33-year-old Peterson, a veteran of 10 major league seasons, hit .211 with six home runs and 37 RBIs for the Athletics and Diamondbacks, including .183 with no homers and nine RBIs in 41 games and 106 plate appearances with Arizona.

Cecconi, a 24-year-old right-hander who made his debut Aug. 2, pitched two scoreless innings in the NL Championship Series win over the Philadelphia Phillies. He appeared in Games 2 and 5, both losses.
