Matusz was ejected in the top of the 12th inning Saturday after umpires found a foreign substance on his arm, according to Joe Frisaro of MLB.com. Matusz faced two batters and gotten both of them out, one with a strikeout. He walked off the mound without showing visible anger. He will likely face a suspension from this incident, similar to Milwaukee Brewers' pitcher Will Smith who was caught in a similar incident earlier this week.
