In recent weeks, this always seemed a possibility. As Trey Mancini came to terms with the idea of a trade, he tried to soak in his final homestand last week at Oriole Park at Camden Yards in Baltimore, cherishing the six years he’d spent in Baltimore. And now, with Mancini headed to the Houston Astros as part of a three-team trade, the chance to take in his surroundings during that final homestand was opportune ahead of Tuesday’s trade deadline as he recalled the moments that made him a fan favorite in Baltimore. “He’s known for the last year and a half really that he’s been the subject of trade speculation and that this was a possibility,” executive vice president and general manager Mike Elias said Monday after announcing the trade.
