Gabrielino’s Angel Acosta is proving more and more that he’s a man among boys. The sophomore pitcher dazzled fans with yet another brilliant performance Friday, tossing a no-hitter and striking out 17 to lead the Eagles to a 7-1 Mission Valley League victory over El Monte. Acosta (6-4, 2.00 ERA) became the first pitcher in school history to pitch a no-hitter, posting a new single-game strikeout record and single-season record for most strikeouts. According to MaxPreps, Acosta is the nation’s strikeout leader among sophomores. The 17 strikeouts puts him at 100 this season, surpassing Calvin Chambers’ record of 98 set last season. El Monte will host the Eagles on Friday. It was just a few weeks ago when Acosta, who also leads the team in batting with a .467 average, pitched seven scoreless innings in relief, struck out 14, and went 3 for 4 with two doubles and three RBIs to help Gabrielino storm back from a 15-1 deficit to beat St. Anthony 21-17 in 11 innings.
