Brad Halsey’s acclimation process lasted exactly one start. As a 23-year-old Yankee prospect in 2004, Halsey limited the Dodgers to just two runs on five hits in 5 2/3 innings, earning the win in his major league debut.

As a reward, Halsey’s next two starts came in front of sold-out Yankee Stadium crowds who agonized and analyzed every pitch the Houston native threw. Asking someone barely out of college to pitch against the Mets and Red Sox-the Bombers top two rivals in terms of fan passion-can be a daunting task for any pitcher. While Halsey lost to the Mets, he held his own against the Red Sox and picked up a no-decision.

Five years later, Halsey is coming off arm surgery and looking to revive his career. That journey can take a positive turn tonight when Halsey takes the mound as the Ducks Opening Day starter against Southern Maryland.

Halsey last pitched in the majors in 2006, going 5-4 for Oakland. In 40 career starts, he is 14-19 with a respectable 4.84 ERA. The Yankees former eighth-round draft pick and University of Texas standout is just 28 and looking to complete a comeback following his July 2007 surgery to repair a torn labrum.

“I just take it one second at a time and enjoy every time I’m able to throw a ball and my arm feels good,” Halsey said.

The 6-1, 187-pound left-hander impressed Ducks manager Gary Carter and pitching coach Dave LaPoint enough to warrant the Opening Day assignment, which Halsey said is an honor at any professional level.

“It absolutely is an honor,” Halsey said. “There are a lot of guys in this clubhouse who have as much or even more major league experience than I do. Anytime you have an opportunity to start Opening Day, it’s a great thing.”

Former Ducks Bill Pulsipher was one of the players Halsey consulted in researching the Ducks. Earlier in the decade, Pulsipher parlayed a stint with the Ducks into another major league job, giving players like Halsey someone to emulate in trying to make a comeback into affiliated baseball.

Before coming to Long Island, Halsey pitched winter ball in Puerto Rico, where his new team got an endorsement.

“Just knowing some of the guys and for the last two years sitting at home doing rehab, I noticed there were a lot of good players in this league,” Halsey said. “For someone in my situation who has a lot to prove; this is a good place to do it.”

LaPoint said the Ducks signed an outstanding defensive catcher in John Pachot, who spent the last two seasons playing against the Flock for the Newark Bears. Pachot’s game-calling could help Halsey, along with playing under a Hall of Famer catcher in Carter.

“My experience is that catchers make the best managers because they have knowledge of the entire game” Halsey said. “Not only are they immersed in the relationship between the battery, they also have to take a bat up there all the time, which as pitchers, we don’t always have that experience.

“As a catcher, he [Carter] knows all facets of what goes on out there.”
