"We invited Sean to come in so he'd get a chance to meet us, see everything, introduce him around, see our facilities," general manager Frank Wren said. "As he's contemplating his decision, it gives him a chance to get more familiar with Atlanta and everything going on here."
Gilmartin, whose season ended June 13 when the Seminoles lost to Texas A&M, resumed working out last week after taking some time off to relax in Tallahassee, Fla. He threw 120 1/3 innings over 18 appearances this year for Florida State, but believes he'd be able to pitch this year once he signs.
"I'm definitely going to be ready for it, I think," he said. "Obviously that's up to the organization if they want me to do anything like that. I'll definitely be ready to play whenever I get the call."
Gilmartin -- who compiled a 12-2 record with a 2.09 ERA this season -- knows his decision will be an important one, but doesn't necessarily think it will be one that's incredibly difficult.
"I'm not really sure how tough the decision is going to be, but it's definitely what I want to do," he said. "I want to play Major League Baseball. It's been my lifelong goal ever since I can remember. As far as the decision being tough, I don't think it will be a tough one. I'm very excited and I'm ready to play."
Gilmartin, who is represented by Ryan Gliechowski in Gainesville, Fla., believes he steadily improved during his time with the Seminoles. He was a member of the First-Team All-ACC squad in 2011 after going 9-8 with a 5.24 ERA in 2010.
"I think every single time I went out to pitch last year, I tried to improve myself, whether it be mentally or physically or with the pitches that I made," he said. "I tried to learn something every single time out. I feel like I accomplished that and I was very pleased with the kind of season I had."
Gilmartin was getting his first look inside Turner Field on Tuesday and had the opportunity to meet third baseman Chipper Jones.
"I'm very excited with everything that's going on. It's definitely a fun process," he said. "Obviously, I've never done this before, so it's the first time for me doing everything. I'm just enjoying everything."
