Giants’ Angel Pagan extends streak, exits with ailment

Angel Pagan has an 18-game hit streak, but who would know?

“It’s like when a guy’s throwing a no-hitter — you don’t mention it,” said one Giant who didn’t want his name attached to his comment, fearing he’d jinx Pagan.

Even with Joe Panik back on track after coming off a concussion, Pagan is the undisputed No. 2 hitter, taking Panik’s old spot.

Pagan extended his streak with a first-inning bunt single but exited after two at-bats with right groin tightness, which he felt pursuing a ball in left field.

Pagan is expected to miss Sunday’s series finale, and the Giants hope he’ll return for Tuesday’s opener at Dodger Stadium.

“We think he’ll be OK,” manager Bruce Bochy said.

“No reason to change that now,” said Panik, who batted eighth Saturday and tripled and scored a run.

Moore is 0-3 in four starts since being traded to the Giants. …

Denard Span has nine hits in his past 14 at-bats. ...

Eduardo Nuñez hit a bases-loaded double and is batting .250 (in 72 at-bats) with nine RBIs as a Giant. ...

Bartolo Colon won his 229th game to tie Luis Tiant for third place among Latin Americans.

“He basically throws one pitch and changes speed with the fastball,” Posey said.

After Bruce Bochy passed Jim Leyland with his 1,770th win as a manager, his next target became Lou Piniella, who won 1,835 games.
