The trade deadline has passed, leaving several prospect faces in new places. The most notable deadline deal involved the Arizona Diamondbacks, who shipped ace Zack Greinke to the Houston Astros for four prospects, none of which were named Kyle Tucker.

Seth Beer hasn't stopped hitting since being drafted in the first round last year out of Clemson, hitting a combined .310/.408/.556 with 25 home runs and 91 RBI through 101 games between High-A and Double-A. Hurlers Corbin Martin and J.B. Bukauskas had been roughed up of late, but both possess plenty of upside and should see the majors sooner rather than later. And 25-year-old Josh Rojas, a 26th round pick out of Hawaii in 2017, is batting .330/.417/.592 with 21 home runs, 76 RBI and 33 steals in 100 games between Double-A and Triple-A. Add in the large amount of money Greinke is owed and the Diamondbacks appear to have received a hefty haul, even though the Astros now boast the best rotation in baseball and are heavy favorites to win the World Series.
