SAN FRANCISCO: Indians Triple-A catcher Roberto Perez is batting .410 over his first 14 games with the Clippers this season after struggling to hit .200 last year. But Perez, 25, has a good reason for such a big improvement this season — he’s healthy.

Last year, Perez was plagued by a nerve condition, Bell’s palsy, which causes te=mporary paralysis of the muscles on one side of the face. The condition comes on suddenly, but usually clears up on its own within a few weeks.

Indians farm director Ross Atkins said Perez wasn’t able to close his left eye for most of last season. In fact, he said the condition didn’t dissipate until this spring training.

“He couldn’t close his eye for months,” Atkins said. “He couldn’t sleep. It affected his ability to see the ball. He couldn’t blink. The dryness, the fatigue, the mental drain. He had to put a patch on to sleep … It was a slow, gradual improvement. But you can still see it in his face. When he smiles, you really see it.”

FIESTA BY THE BAY — Sergio Romo’s entrance in the ninth inning for the Giants could be the best thing going in baseball right now. With the catchy song EL Mechon — The Lock — by Banda MS blaring throughout the stadium, the Giants’ closer’s walk-up song turns sold-out AT&T Park into a huge Mexican fiesta. Many fans get into the act by donning sombreros, shaking maracas and dancing in the aisles. Having converted all six of his save opportunities to date this season, Romo has given San Francisco fans plenty to dance about.

SPEAKING OF SELLOUTS — With the Giants’ 258th consecutive sellout at AT&T Park on Sunday, the Giants now own the record for the longest streak of sellouts in National League history, surpassing the Philadelphia Phillies (July 7, 2009-Aug. 5, 2012).

Currently the longest active streak in the big leagues, the run began on Oct. 1, 2010, as the Giants approached the NL West title. The Boston Red Sox own the all-time record of 794 consecutive home sellouts (May 15, 2003, to April 8, 2013) at Fenway Park. The second-highest streak is the Indians’ 455 consecutive sellouts at Progressive Field (formerly Jacobs Field) from June 12, 1995, to April 2, 2001.
