CHICAGO — On the whole, actor Freddy Rodriguez doesn’t have much in common with basketball star LeBron James.

But Rodriguez points to one important similarity: At a young age, he, too, faced the potentially life-changing decision of whether to “go pro.”

In 1994, a year after graduating from Lincoln Park High School, Rodriguez considered three options. He could enroll at Columbia College Chicago (his parents’ preference), he could finish the audition process for the Goodman Theatre’s production of “The Merchant of Venice,” or he could take a role in the Keanu Reeves-helmed period film, “A Walk in the Clouds.”

He chose to do the film.

“LeBron went straight out of high school into the professional basketball world, and that was the choice I had to make, whether I was going to go pro or go to school,” Rodriguez said. “I guess my justification was I could go to school to learn drama, where here I could do it firsthand and be in the professional world, so I chose to go pro.”

He has never looked back.

Most known for his Emmy-nominated turn as ambitious mortician Federico “Rico” Diaz in HBO’s “Six Feet Under,” Rodriguez has successfully bounced between TV and film throughout his 20-year career: His lengthy IMDB page lists at least one project every year since his 1994 screen debut.

Rodriguez’s newest TV show, NBC’s “The Night Shift”, which premiered No. 1 in its time slot, according to the network, and has maintained an audience of about 6 million per episode, follows doctors who work the night shift at San Antonio Memorial.

Rodriguez plays the exceedingly complex Michael Ragosa, the nighttime hospital administrator charged with keeping the budget balanced and the resident bad-boy doctor in check. The series’ sixth episode, which will air Tuesday, deals with a company of soldiers that is rushed to the hospital after a horrific bus crash.

Rodriguez, 39, oozed swagger recently as he walked into the executive lounge at the Drake Hotel. Dressed in jeans, a black T-shirt and a black leather jacket, his jet-black hair parted just so, he looked like a reincarnation of the Fonz.

He’s happy with his life and his career, he said, and on this gloomy, rainy morning he was inclined to reminisce.

“Every day I feel blessed and incredibly grateful,” he said with a wide, toothy smile. “Especially now that I’m coming up on the 20th anniversary of ‘A Walk in the Clouds’ and ‘Dead Presidents’ and my first round of films, which has really put things into perspective and has been an incredible reality check for me. It makes you grateful.”

Rodriguez’s West Coast lifestyle is a far cry from his upbringing in then-perilous Bucktown. In 1991, 16-year-old Rodriguez told the Tribune that he had been at “very, very, very high risk” of falling into gang life until, at 13, he wound up in a play produced by the nonprofit Whirlwind Performance Company.

That show started him down the path that would eventually lead to Hollywood.

As a soon-to-graduate eighth-grader, Rodriguez sported a smirk as he took a bow after performing Whirlwind’s “City of Neighborhoods” at the Blackstone Theatre (now called the Merle Reskin).

That was the moment Rodriguez decided to become an actor, he remembered.

“I starred in that play and I just sort of knew what I wanted to do,” he said. “And it’s all I have done since I was 13.”

A 1989 Tribune article about the show said, “bright and self-assured” Rodriguez “stole the show in the leading role,” a sentiment that Whirlwind founder Karl Androes echoed. (The Whirlwind Performance Company exists today with a slightly modified mission as Reading in Motion.)

After Whirlwind, Rodriguez studied drama at Lincoln Park High School and tried to stay focused.

“Getting to do my first play at the Blackstone and starring in it, you build up a healthy ego,” Rodriguez said. “I had an agent at that time and I was auditioning, so my focus was more about doing that, trying to land a commercial or TV show, as opposed to school. I remember the first day of freshman year, (my teacher) slapped a book down in front of me and said, ‘This year we are going to learn the history of drama.’ I remember going, ‘What? The history of drama?’ I was just sort of restless. I just wanted to act.”

On “The Night Shift,” Rodriguez’s hospital administrator Ragosa is not well-liked by many of the doctors, a casualty of having to enforce rules. Ragosa harbors desires to be a doctor himself, but a degenerative eye disease forced him into administration.

With blood and guts galore on the show, Ragosa’s quiet, paper-pushing role could get lost in the hands of a lesser actor. Instead, Rodriguez infuses the role with intrigue and strength. Rodriguez’s quiet moments resonate just as strongly as the action in the ER.

“Freddy never plays a stereotype,” said Daniella Alonso, one of Rodriguez’s co-stars. “He just tries to play that person’s truth, and that truth comes through no matter who he’s playing. He’s just so intuitive.”

“There is never a point where we give Freddy something and he is going to go, ‘I dont know how to play this,’” said Gabe Sachs, co-creator of “The Night Shift.” “He knows. He knows his stuff.”
