But let's talk about this filthy pitch, a sweeper that starts outside to Seattle Mariners slugger Rowdy Tellez and comes darting back over the outside corner for strike three. It apparently had over two feet of break! It's no wonder Severino was so fired up at this one.

New Athletics ace Luis Severino delivered an unforgettable performance on Opening Day, tossing six shutout innings against the Seattle Mariners at T-Mobile Park. His final stat line: three hits, four walks, six strikeouts and zero earned runs on just 99 pitches.

Severino did not factor into the decision Thursday, allowing three hits and four walks over six scoreless innings against Seattle. He struck out six. Severino gave a strong performance in his A's debut as his bullpen blew a late lead.
