Nationals at Rockies preview DENVER (Interstat) — The Washington Nationals and Colorado Rockies meet for the second game of a three-game series Tuesday night at Coors Field, with both teams looking to build momentum after a scoreless opener. Washington (50-50) arrives with a .500 record and coming off a 5-2 win Sunday at Oakland, where left-hander Foster Griffin threw seven innings of one-run ball. The Nationals have not confirmed their probable pitcher for Tuesday, though both right-handers Miles Mikolas (3-7) and Michael Lorenzen (3-9) are listed as possibilities. Left-hander Foster Griffin has emerged as a key contributor for Washington. The 27-year-old has won four consecutive starts, including Sunday’s outing in Oakland and an eight-strikeout performance July 8 against Houston. Over his past four starts, Griffin has a 1.04 ERA across 26 innings. Colorado (40-61) enters in last place in the National League West but showed offensive firepower Sunday despite a 9-6 loss to Cincinnati. Catcher Hunter Goodman went 3-for-4 with three home runs and five RBIs, though he was 0-for-4 in the series opener Monday. The Rockies have lost five of their past six games but have posted double-digit run totals in two of their past four home contests. Colorado’s pitching staff has struggled, allowing at least six runs in four of its past five games. Washington’s offense has been inconsistent but exploded for 23 runs July 17 at Oakland. Shortstop CJ Abrams has been a steady contributor, going 2-for-4 with a home run and two RBIs in Sunday’s win. The Nationals won Monday’s series opener 1-0. Betting odds have Washington as a minus-1.5 run-line favorite, with an over/under of 12.5 runs reflecting Coors Field’s hitter-friendly reputation. A game simulator projects a 4-3 Nationals victory. Following this series, Washington returns home to face Arizona, while Colorado travels to Milwaukee next weekend.
