Jesse Hahn will start for Oakland A's on Saturday, Chris Bassitt headed to disabled list

The Oakland Athletics placed starting pitcher Chris Bassitt on the 15-day disabled list and recalled reliever Andrew Triggs from Triple-A Nashville, the club announced, saying Bassitt has an elbow strain (which is an odd turn of phrase, because there isn't an "elbow muscle" to strain). There is no word yet on the severity of the injury.

The A's will call up Jesse Hahn to start Saturday's game against the Houston Astros, reports Susan Slusser of the San Francisco Chronicle, citing a source with knowledge of the situation. Kendall Graveman was previously listed as the probable starter for Saturday's contest.

There was concern for Bassitt's health after his velocity dropped noticeably in the fourth inning of his loss to the Detroit Tigers on Thursday following a 40-pitch third inning:

CSN California's Joe Stiglich indicates that Graveman and the rest of the rotation will be pushed back a day:

Can confirm that Jesse Hahn starting Saturday for #Athletics. Would push Graveman, Hill, Gray back a day.

This would also give Sonny Gray an extra day of rest after a 40-pitch second inning of his own ended his Wednesday start, the shortest of his career.

The A's also selected Sean Manaea's contract, transferring Sam Fuld to the 60-day disabled list to open a space on the 40-man roster. Catcher-outfielder Matt McBride was optioned to Triple-A Nashville.
