 Big league debut this evening. The DMV native was hitting .353 with 10 homers and 37 RBI over 52 games with AAA Rochester this year. Nats host the New York Mets tonight at .645 on 1500 AM. That's our game to watch in this week's Nats Notebook on the sports page at WTOP.com. Orioles lose to Texas 11-2. Cole Irvin coughs up five runs over three and two-thirds frames. Birds take three of four from the very team that eliminated them last October, though.
