The Nationals will hit the halfway point today, and they find themselves in the painfully familiar position of needing a win to get back above .500. Gio Gonzalez, who has a 2.32 ERA in 10 starts since the beginning of May, will face Mets prospect Zack Wheeler, who is making his third career start. Wheeler, a 23-year-old right-hander, is 1-0 with a 3.18 ERA. Talk about the game right here.
