Winner: Yu Darvish
Aside from one rough game, Yu Darvish had a phenomenal May. April was essentially the same; one nine-run shelling dented an otherwise solid start to the season, but the Padres went 3-2 in his starts.
May was even better, as Darvish made two seven-inning starts (he had none in April) and his third shutout performance of the year.
Loser: Steven Wilson
After only allowing four earned runs across 10 appearances in April, Wilson struggled a bit in May. Wilson allowed three earned runs twice in his eight appearances, including getting his first blown save and loss against the Atlanta Braves on May 14. He was charged with a blown save back on April 11, but still got the win.
Wilson is far from the worst reliever around, but his struggles in May didn’t help his team shut down the opposition. They went 5-3 in his games.
