Ogando left in the sixth inning of Game 4 with a strained left quadriceps muscle and will not be able to pitch the remainder of the series. Nippert, who was on the ALDS roster, has appeared in one postseason game, giving up a solo home run to Carl Crawford in the ninth inning of Game 3 against the Rays. The Rangers lost, 6-3.
"We needed a righty," Washington said. "Nippert is a bullpen piece we've had down there all year."
The Rangers felt more comfortable with Nippert in the bullpen over Scott Feldman, another right-handed option. The club already has lefties Derek Holland, Darren Oliver and Michael Kirkman in the bullpen, so they didn't want another left-hander against the Giants.
Ogando retired his first five batters Sunday night before throwing his second pitch to Juan Uribe with two outs in the sixth inning. The slider was way outside and went to the backstop. Athletic trainer Jamie Reed, manager Ron Washington and pitching coach Mike Maddux came out to check on him.
"It started bothering me in my second inning and it got a little worse and a little worse and finally I really felt it pull on the last two pitches," Ogando said after Game 3 late Sunday. "I feel bad because it's at a point where I can't help the team anymore. Things happen that way sometimes, but it's disappointing."
Ogando was relieved by Darren Oliver, who got Uribe on a foul pop. Ogando had taken over for starter Tommy Hunter, who allowed two runs and five hits over four innings. Ogando threw 3 2/3 scoreless innings with six strikeouts and no walks in two World Series games.
