Watch: Padres reliever ejected after foreign substance check before throwing a single pitch

First base umpire Todd Tichenor made the call. After the game, Tichenor told reporters that the right-hander’s left wrist had been “too sticky, very sticky,” via AJ Cassavell of MLB.com. Suarez denied using any illicit substance, saying he’d simply applied his typical amount of sunscreen for a day game in San Diego.

Pitchers ejected after a foreign substance check are subject to an automatic 10-game suspension. MLB will presumably formally announce Suarez’s ban tomorrow. He has an appellate right, though an appeal would go in front of an MLB official for adjudication. As a result, the three players previously suspended for foreign substances this season — Max Scherzer, Domingo Germán and Drew Smith — all waived their appeals. Suarez said he hasn’t yet decided whether he’ll do the same.

In all likelihood, the Friars will be without one of their better high-leverage arms for the next week-and-a-half. Suarez posted a 2.27 ERA in 47 2/3 frames last season and subsequently re-signed on a five-year, $46M free-agent guarantee. He missed the first half of this year with an elbow injury. He has allowed seven runs in 13 1/3 innings since returning. Teams aren’t allowed to replace players who have been suspended for an on-field rules violation, so the Padres would have to play with a 25-man roster for the duration of Suarez’s expected suspension.
