Johnson (1-3) took the loss against the Tigers on Saturday, allowing two unearned runs in five innings while giving up five hits and striking out five.
Both runs came in the second inning: Victor Martinez reached on a one-out throwing error before a single and a two-out double from Jose Iglesias that plated the runners. Johnson lowered his ERA to 3.81 but, with a 7.8 K/9 and 2.8 BB/9, carries less-than-stellar command peripherals to back it up. With several Red Sox hurlers on the disabled list, however, Johnson should have at least a few more turns in the rotation, with the next one lining up for Thursday against the Twins.
