Iván Herrera struck out all four times up against the Angels in Monday’s loss.

Herrera has been struggling the last couple of weeks, but a four-strikeout game from a guy with a 16 percent K rate is pretty unexpected. He’d never had one previously in 301 games as a major leaguer. Herrera is 6-for-40 with no extra-base hits in his last 10 games.
