Walker allowed three runs on five hits and five walks across 4.2 ennings en route to a no-decision Tuesday against the Nationals. He struck out six.
Walker built up his pitch count while working through rallies in the first and third inning before his removal after throwing 117 pitches with two outs in the fifth. His five walks were a season high, but he induced six groundouts to help mitigate the damage. Thanks to ample run support, he narrowly missed improving his record to 4-1 and will take a 4.19 ERA into Sunday's difficult road matchup with the Rockies.
