Jordan Zimmermann, and his Nationals replacement Joe Ross continued their parallel successes on Saturday. Zimmermann’s April might make Nationals fans believe the team made a mistake letting him go to the Tigers via free agency. Zimmermann held the Twins to one run in seven innings, walking none and striking out seven, but allowing his first home run of the season. That outing left him with a 0.55 ERA for the season.

Meanwhile, Ross allowed the Cardinals just one run in six innings to bring his ERA to 0.79. His walks and strike outs were not as good as Zimmermann’s, walking two and striking out four. Ross, however, has yet to allow a home run.

Both are undefeated. Nationals fans should be happy, however, since Ross is seasonal age 23, and Zimmermann plays 2016 as a 30-year-old. There’s a lot more upside with Ross.
