Maeda is expected to start Sunday's game against the Reds, Andy McCullough of the Los Angeles Times reports.
Maeda's next appearance was supposed to come out of the bullpen this week, but manager Dave Roberts will choose to deploy him in the rotation later in the week in order to afford his starting pitchers an extra day of rest. The 29-year-old owns a 4.95 ERA and 59:17 K:BB through 56.1 innings this year (10 starts, one relief appearance).
