Jered Weaver of the Los Angeles Angels of Anaheim received a six game suspension on Tuesday for throwing at Alex Avila of the Detroit Tigers. Note that Weaver is not afraid to pitch inside to left-handed batters.
Compare that to the league average:
Weaver tends to come farther inside than most righties, and up and down a bit more. His high pitches usually end up over the plate, not near the batter's head.
Look where he threw the pitch to Avila:
That is not where Jered normally pitches when he misses. It's off the chart.
