• Henderson Alvarez, who opened the season on the disabled list with right shoulder inflammation, is throwing live bullpen sessions in Jupiter. If he continues his progression without any setbacks, he could be ready to join the rotation within the first 10 days of May.
• Shortstop Adeiny Hechavarria, on the DL since Thursday with a right elbow bruise, is rehabbing in Miami. The hope is he will be ready around the time he is eligible to be reinstated on May 3.
• John Maine, designated for assignment last Friday, has been outrighted to Triple-A New Orleans.
• Outfield prospect Jake Marisnick is a couple of days away from being game ready after aggravating his left wrist while making a catch in an extended spring game. Marisnick will eventually join Double-A Jacksonville.
• To deal with the cold weather, several Miami players were planning on wearing ski masks, as well as plenty of layers, during Tuesday's doubleheader. Third-base coach Joe Espada noted that coaches are not allowed to wear jackets, but he will wear a hoodie under his jersey.
• Only the first game of the doubleheader is being televised by FS Florida.
