Teams — Washington brings the stronger overall offensive line with a .767 OPS and 552 runs, along with a .252 average. The Nationals’ pitching staff has a 4.80 ERA and 1.40 WHIP, and they are 5-5 over their last 10 games. Colorado has a .745 OPS, 487 runs, and a slightly higher .255 average, but the run production trails Washington by a notable margin. The Rockies’ staff has struggled more, posting a 5.47 ERA and 1.52 WHIP, and they are 3-7 in their last 10.
