BOSTON — Angels manager Mike Scioscia is well aware of David Ortiz’ postseason success. But he doesn’t think it’s necessarily a case of Ortiz stepping up his game in the postseason spotlight.

“He’s had a pretty terrific season to say he just rises to the occasion,” said Scioscia of Ortiz, who batted .332 with 52 doubles, 35 homers and 117 RBI this season.

“I think he’s able to, as we talk about some pitchers, slow down the game. He’s able in the batter’s box to slow some things down and stay within himself. I think he performs well in any situation. I think it’s a matter of maintaining your game and not trying to do too much and he does that as well as anybody, which is why he has had success late in games, early in games, whatever the situation.

“He’s very focused,” continued Scioscia. “He’s got a lot of confidence in the batter’s box and he’s a tough out. He’s about as good a mistake hitter as you’re going to see in the game today. As far as a clutch hitter late in a game, you’re not going to see many guys better than David.”

Guerrero is ‘probable’

Scioscia said slugger Vladimir Guerrero, who has been hampered by a triceps strain, will “probably” be healthy enough to start in right field tonight for Game Two of the ALDS at Fenway Park.

Scioscia said Guerrero worked out yesterday. Whether he starts in the outfield may depend on how he feels today after having been through a workout.

If he can play in right, Scioscia said that will give the Angels more batting-order options in an attempt to create what the manager calls “batter’s box” offense. He said the team can try and use its speed and create runs all it wants, but none of it means anything unless they can get “batter’s box” offense to put runners on base.

One-legged, one-eyed

The Angels’ outfield corps has been depleted. Not only was Guerrero out of the starting lineup Wednesday night in Game One — though he went 2 for 4 as the designated hitter — but the Angels also are missing center fielder Gary Matthews Jr., who is hobbled by a sprained ankle.

And then there’s left fielder Garret Anderson. After Wednesday night’s game, his right eye was virtually swollen shut because of conjunctivitis. Obviously, trying to hit big-league pitching with one eye, especially with your lead eye closed, is very difficult, but Scioscia said that unless something happens to Anderson’s left eye, he expects Anderson to start tonight.
