Zimmermann's record (9-6) is average. His stuff and location are anything but. Over his last nine starts, he's allowed one run or fewer in eight of them. You hope people start learning about Zimmermann sometime soon. It's about time this guy hears his name mentioned among the league's best hurlers, because that's a group in which he's proven he belongs. All season long, we've talked about how the Nationals' starting rotation will make it so that lengthy losing streaks are few and far between. When you have this group of five starters, all of which have ERAs below 3.60, you've got a good chance to emerge victorious on any given day. To that point, the Nationals' longest losing streak of the season is five games. Only twice all year have they dropped more than three games in a row. On the flip side, they've now won six in a row for the third time this season and have seven winning streaks of four or more games. Through this most recent turn in the rotation, the Nationals' five starters have pitched to a 1.89 ERA. They've allowed just 20 hits in 33 1/3 innings, walked seven and struck out a total of 34 batters. That's how a team ends up with the best record in the major leagues. At 69-43, the Nats are now 26 games over .500 after their four-game sweep of the Astros, find themselves at least three games above all other 29 big league teams and are on pace for 100 wins.
