It's not uncommon for some of the nation's top prep prospects to have a no-hitter or two to their name upon leaving high school. But what Oyster River Regional (N.H.) junior left-hander Brennen Oxford has done in May is virtually without parallel from coast to coast.

Oxford ran his hitless streak to 30⅔ innings Thursday afternoon after recording his fourth consecutive no-hitter, striking out 13 batters in a 6-0 win over Hollis-Brookline to run his season record to 4-1. Given the regularity with which Oxford is posting a clean sheet, one can't blame the Bobcats for their subdued celebration following the win.

Over this string of no-no's, Oxford has 46 strikeouts to just 13 walks, including a 15-K performance in a win over Laconia on May 10.

"This is pretty darn special. Right now he's just locked in," Oyster River coach Craig Walfield told Seacoast Online's Dan Doyon. "I've never seen him like this. He wants the ball, knows when his starts are coming and he's just stayed himself. He's just a kid and he's having a good time, but he's turned into a monster."

Reflecting on his outing Thursday, Oxford told Doyon, "It was probably the best of the four but still not good enough. I expect a lot out of myself. I had a few walks, so there is always something to work on."

Regardless of how the rest of the spring goes for the 6-foot-2 Oxford, a Wake Forest commit, eyes are sure to be locked on him headed into the busy summer evaluation period, when elite players often square off at marquee showcase events across the country.

"Everything I know about the kid is still early, but given he throws strikes, is left-handed and is a really good athlete, he's definitely going to be a guy to follow," says an American League scout. "He runs well. He swings the bat well. Those two things add value. For me, if they can hit and provide some form of athleticism, that keeps their arm pretty well. He's definitely going to be someone to follow there on the circuit."
