This deadline trade completed one of the best pitching staffs in baseball history. Oswalt finished 6th in the Cy Young voting in 2010 and provided strong postseason outings. While the trade was also fruitful for the Astros, the excitement surrounding the Oswalt trade as the Phillies geared up for one last run electrified the fanbase.
However, the Phillies ultimately gave up the most in on field, major league production in this move. Happ has been a solid starter for a number of teams, even winning 20 games for the Blue Jays in 2016.
Villar is going into his sixth year in the majors, as he has begun to excel with the Brewers as a perennial starter, even leading the league in stolen bases in 2016. Gose has bounced between the minors, but has started 50 major league games in four of his five seasons for Toronto and Detroit.
