Kenta Maeda was one of the Dodgers who hit the disabled list in May despite there being some questions as to whether he really had a hurt hamstring or not. Maeda was pretty pedestrian in May despite only allowing three earned runs or less in every start. His best start was before his DL stint when he pitched into the ninth inning against the Pirates and allowed only two earned runs.
Maeda finished the month of May with two starts against the Cardinals, and they were almost a carbon copy of each other. Maeda allowed three earned runs in the first inning, settled down, and the Dodgers won both games.
Maeda gets a C because outside of his start against the Pirates he is not pitching deep into games at all. His last start of the month was only four innings, and the other two starts he only went five innings. While Maeda is starting to have success with his new cutter, he needs to cut down his pitches per inning to go at least six innings each time out.
