The first-round selection will now get his wish.
The Braves announced on Friday that they reached an agreement with Gilmartin, a left-handed pitcher from Florida State University who was taken with the 28th overall selection in this year's First-Year Player Draft. He signed for $1.134 million.
"I'm very happy," Gilmartin said. "Obviously, the Braves organization is, in my opinion, one of the better organizations in Major League Baseball. So I couldn't be more happy with my decision to sign."
Gilmartin -- who went 12-2 with a 2.09 ERA in 120 1/3 innings for the Seminoles this season -- reported to the Braves facility at the Wide World of Sports Complex on Friday.
"I'm sure the Braves organization has a throwing program for me," Gilmartin said. "I don't know what that entails right now. I'm perfectly comfortable doing whatever they want me to do. I know I'll be ready."
General manager Frank Wren said Gilmartin wouldn't be ready to leave the Spring Training complex for 10 days to two weeks. From there, Wren noted a start in the Gulf Coast League or in Rome as possible options. In all, Gilmartin could wind up making six or seven Minor League starts before the season concludes.
"He could move very quickly," Wren said. "He's faced a good level of competition."
Gilmartin has used the last month to rest both mentally and physically, as he hasn't pitched since FSU was eliminated from the NCAA Tournament on June 13.
"After we played Texas A&M in the Super Regional, I took off maybe two weeks," he said. "After that, [I] started working out again, just started playing catch. [I've] just been playing catch basically for the past month or so -- keep my arm in shape. I haven't really thrown off the mound since then."
He used some of that down time to visit Turner Field, where he received the opportunity to meet those in the front office and in the clubhouse.
"[He's] very impressive as a kid," Braves manager Fredi Gonzalez said. "[He's] very mature. I think he knew what he wanted and asked real good questions. ... I could see him moving through the ranks pretty quickly."
