• Shortstop Adeiny Hechavarria (right triceps) will begin his rehab assignment for Class A Advanced Jupiter on Friday. The best-case scenario is that Hechavarria will come out of the game feeling ready to rejoin the big league club. If that is the case, he could be with the Marlins and active at St. Louis on Sunday. However, it is appearing that the shortstop will play at least a couple of games with the Hammerheads. If he goes that route, he will join the team during the series at Arizona, which begins on Monday.
• Tom Koehler, on the paternity list, remains on schedule to start on Monday in Arizona. His wife, Ashley, is expected to have the baby at any time.
• One more international signing was announced on Thursday. The Marlins have signed right-hander Jose Veras from Venezuela.
