Oakland A's will call up Cody Martin to start Tuesday, Chris Bassitt out with right shoulder soreness

The Oakland Athletics will call up Cody Martin Tuesday to start against the Los Angeles Angels, according to the beat writers (John Hickey, BANG). Chris Bassitt was previously listed as the probable starter, and Manager Bob Melvin told beat reporters that Bassitt has soreness in his right shoulder (Ron Kroichick, SF Chronicle). Bassitt will get an MRI tonight (Hickey).

Martin will be one of the first minor league players called up with rosters expanding on September 1. The A's acquired Martin for an international bonus slot in early July from the Atlanta Braves, when he had a 2.10 ERA in 34⅓ innings for Triple-A Gwinnett. His fortunes have fallen since joining the Nashville Sounds, however, where he owns 5.33 ERA in 10 starts over 54 innings. He has struck out 51 and walked 30 in Nashville.

Martin started the year pitching in relief for the Braves, making 21 appearances and finishing with a 5.40 ERA while striking out 24 and walking seven. Tuesday's game will be his first career major league start.

With rosters expanding on Tuesday, the A's need not place Bassitt on the disabled list. However, if the injury proves to be something that causes the A's to shut Bassitt down for the year, the club could place him on the 60-day disabled list to allow the activation of an additional player not currently on the 40-man roster, above and beyond the players that could be added for Jesse Hahn and Kendall Graveman, who are presently on the 15-day disabled list.
