Astros third baseman, Aaron Boone, who underwent open heart, aortic valve surgery in March is set to rejoin the team Friday in Arizona and is likely to be activated September 1 when rosters can be expanded.

Aaron Boone – Heart Valve Surgery Patient

Boone, 36, has been on a Minor League rehab assignment since August 10 and had 15 at-bats for Double-A Corpus Christi before moving to Triple-A Round Rock, where he was 0-for-4 in two games.

The Astros open a three-game series Friday against the Diamondbacks in Phoenix, where Boone lives.It’s not known how much playing time Boone will get, but the fact he will return to the field is a major accomplishment.

No stranger to overcoming adversity, Aaron Boone has relied on his tremendous work ethic to persevere through his lengthy rehabilitation. He draws strength from exceptional family support, as well as an Astros organization refusing to shut the door on him.

Boone’s refusal to throw in the towel represents a positive influence for all patients who understand the challenges and frustrations associated with overcoming adversity.

Keep on tickin Aaron!
