Since coming out of the Speedforce and getting the huge amp this season, they've been mostly using plot device to keep the story going. Like either fighting opponents with BS hax powers that can affect him regardless of speed (like Hazard's probability powers or Killgore's technopathy), or writing him out of the story, like having him thrown in jail for a few episodes, or temporarily giving Iris his speed etc. The actual jobbing so far has been fairly minimal. But I already know that there will likely be a fight in the next few episodes where DeVoe manages to tag him despite his speed. Cuz that's how the CW rolls.
