Alex Peitsch is such a stickler for accuracy that when asked recently which of his most-often listed weights was real — 205 pounds or 220 — he jumped on a scale in his bedroom and provided the answer to a fraction of a pound.

“I’m actually 215.4,” the Notre Dame freshman long snapper said cheerfully and matter-of-factly.

Attention to precision is such a constant when he steps onto the football field that it’s a big reason why Peitsch walks into ND with the fewest impediments in the Irish freshman class toward being at the top of the depth chart at his respective position when the Irish open the 2020 season at Navy, Sept. 5 or 6.

“I don’t think about the end too much, about what’s going to happen,” Peitsch said. “I’m just lifting, snapping, running and putting all the work in.”

In a twisted way, the COVID-19 pandemic actually gave him more of an opportunity to put in work and hone his niche role.

For the past three years, Petisch attended St. John’s College High School in Washington, D.C., roughly 25 miles one way from his parents’ home in Ellicott City, Md.

“But the commute wasn’t 25 minutes,” he said. “It can take as long as an hour and 20 minutes each way. So it’s a lot of D.C. traffic. When our high school classes went to all-online in March, getting rid of that commute was one of the benefits.”

Peitsch already had a home gym set up in his parents’ basement pre-pandemic as well as an elaborate target system that he used to practice his snaps for place kicks and punts.

Over and over and over and over and over.

“My way of keeping it interesting is that I’m always competing against myself,” he said. “My dad comes down the basement and keeps score.

“The field goal target, which is one foot off the ground, is a one-foot-by-one-foot square. The punt target, which is two feet off the ground. is two-by-two. If the snap goes in the target, it’s two points. If it hits the frame, it’s one point. If it misses everything, it’s nothing.

“I love doing it so much and have been doing it ever since I’ve been in high school, it’s kind of an emotional departure leaving those targets behind.”

Petisch is expected to arrive on campus Monday after making the 9½-hour drive with his father. He’ll quarantine for three days, take his first diagnostic COVID-19 test, then presumably begin voluntary workouts June 22 with the returning Irish players and eight other first-time-enrolled freshman teammates.

Required team activities, heavy on conditioning and weight training and including some film study, begin July 13 and run though July 23. From July 24 to Aug. 6 the amount and scope of those required activities expand, per a standardized NCAA blueprint finalized Thursday, and include walk-throughs and meetings.

Training camp kicks off Aug. 7, with the first day of fall-semester, in-person classes at ND three days later.

“I think what I’m looking forward to is just getting to know the guys, because I haven’t gotten to meet many of my teammates,” Peitsch said. “Just trying to get to know some guys, put in some work, build some relationships. Just enjoy myself. I’m looking forward to the daily grind.

“I don’t have any hesitations about Corona and everything. I think Notre Dame has a great plan — with all the tiers, making sure guys are tested and just keeping us in a little pocket.

“I think they’ve done a great job with setting us up and making sure we’re safe but still being able to work out and play football.”

For the past six years, Peitsch hasn’t aspired to be anything on the field other than a long snapper. He started specializing as a seventh-grader, and by his freshman year at Marriotts Ridge High School, he was ranked No. 1 nationally in his class by Kohl’s Professional Camps.

He maintained that ranking after transferring as a sophomore to St. John’s — the same school that produced ND safety DJ Brown and defensive end Kofi Wardlow — and all the way through graduation.

With three-year starter John Shannon turning down a fifth-year option at ND to start a career with the Chicago Police Department, part of the allure for Peitsch to sign with the Irish was the chance to be the No. 1 option at the position as a freshman.

“I think it turned out for the best that I didn’t try to play another position in high school and was able to just focus on snapping,” he said. “And the last time I was timed in the 40 (yard dash), I ran like a 4.9-plus. So I run like a long snapper.”

His first college game will allow him to run out onto the field at Navy-Marine Corps Memorial Stadium in Annapolis, Md., the amended site for the season opener that was supposed to be staged in Aviva Stadium in Dublin, Ireland.

Navy’s home stadium, which has never previously hosted an ND-Mids matchup, is a half-hour drive from Peitsch’s house.

“It’s kind of a bummer that Ireland is canceled,” Peitsch said. “But it’s kind of cool to have my first game back home. My girlfriend, who’s still in high school, lives in Annapolis, actually. I’ve got a lot of family in the area.

“I hope they’ll allow fans and that they can get tickets, because that could be pretty special for all of us.”
