These next two starts will be the most difficult for Harvey to date Matt Harvey will be faced with his biggest challenges of the year in his next two starts against the Reds and the Yankees. Early on, Harvey has proven himself to be one of the best young pitchers in the game and arguably has been the best pitcher in the National League to date.I think Harvey has been fantastic, far better than I even could have imagined, but he hasn't exactly pitched against the strongest teams. It’s not that this is his fault, as his job is to pitch every 5th day against whomever that game falls against. His two strongest opponents have been the Nationals and the Pirates, but he did beat the Nationals early on when they were struggling.Harvey has the type of attitude where he wants to pitch against the best and he seems eager to take on these challenges and prove himself to be better than the rest. These next two starts could be statement games for the young ace as he takes on two very formidable lineups. The Reds are a very good offensive team, who look poised to make another trip to the postseason. I’m looking forward to seeing him take Joey Votto, Brandon Philips, and Jay Bruce head on this afternoon at 1:10 in what will be the best lineup he has seen.His biggest start is slotted to take place on Tuesday against the crosstown rival Yankees. This is the game that both Met and Yankee fans are most excited for during next week's Subway Series. For Met fans, we have had very little to cheer about this season, aside from when Harvey takes the mound. Fans would love to see him shut down the Yankees, giving them at least one day of bragging rights about having the best young arm in the city, and possibly the game.For Yankee fans, well they have had plenty to cheer about as the Yankees have been one of the biggest surprises in all of baseball. They have seemingly done everything right this season, despite all the injuries they have dealt with. The only day the Yankees are not the back page headline? When Matt Harvey starts. They would love to stop this Harvey love fest for at least one game.I don’t have much doubt that Matt Harvey is up to the challenge. I think today will be a great warm-up game of sorts as he takes on this Reds lineup in preparation for his start against the Yankees. These are the moments that he seems to live for and his start against the Yankees may very well big the biggest stage he pitches on this entire season.
