Breaking down the Angels' 2015 Top 30 Prospects

Newly acquired lefty Heaney tops latest list after multiple trades

Breaking down the Angels' 2015 Top 30 Prospects

Several trades in the past year have brought a new look to the Angels' Top Prospects list, especially at the top. Left-hander Andrew Heaney had been the Marlins' top prospect until he was dealt first to the Dodgers and then to the Halos in two trades during the Winter Meetings.

Heaney is one of seven players who rank in the top 10 who weren't a part of the organization at the start of last season. The group includes two others who arrived in trades, the club's top three picks in the 2014 First-Year Player Draft and Roberto Baldoquin, who the Angels signed as an international free agent after he left Cuba.

Third baseman Kaleb Cowart, who went into last year as the team's top prospect, has fallen down the list after struggling in back-to-back seasons with Double-A Arkansas.
