Murphy worked as a starter in the minors throughout the 2019 season. At Double-A that year, he recorded 84 innings with a 4.71 ERA. In 2020, with the minor league season coming to an end, he was only able to get real playing action in the big leagues, pitching six innings into the Toronto reliever box, allowing one earned run on six hits. and two walks.
A constant problem with Murphy has been the injuries, which have continued this year. He was placed in 60-day IL in February and began a rehabilitation mission at the end of May. Since then he has rebounded between the majors and minors, being optioned three times. He topped the AAA batters in 14 scoreless 2/3 innings, with a strikeout rate of 29.3%. Although this also comes with a worrying 13.8% walk rate. At the major league level, he has a 4.82 ERA, but in a small sample of just 9 1/3 innings. The 26-year-old is in his final option year, which means Washington can keep him in the minors for the remainder of the season. But once the 2022 season begins, they are expected to either keep him in the majors or nominate him again for an assignment.
As for Rivera, this ends a very short term in National. The 38-year-old journeyman receiver was released by Cleveland just over a month ago and signed with Washington in mid-July. He was able to appear in just four games for the Nats. Between the two clubs, his slash line for the season is .232 / .293 / .362. He will now be free to sign with other clubs. However, Washington had placed him on IL last week with a bruised elbow. The severity of this injury could determine the level of interest of other teams.
