Extra bases

• On Tuesday afternoon at 1 p.m. ET, Chris Archer will visit The Academy, an alternative high school in Port Charlotte that serves students in the district who would otherwise not complete their high school experience. Archer will speak to and answer questions from an assembly of students at the school.

• Don Zimmer, senior advisor of baseball operations, showed up in camp on Thursday, much to the pleasure of all the Rays.

"He's starting to look as good as he did in that old Brooklyn Dodger baseball card," Maddon said. "He's lost all that weight. He's got that good look in his face. He's got a bounce about him. It was great to have him down here. And the players really, really dig having him."

• Infielder Wilson Betemit, along with right-handers Juan Carlos Oviedo and Juan Sandoval, have still not arrived to camp due to visa issues.

• The Rays have announced four acts for the 2014 Summer Concert Series: Weezer, The O'Jays, Imagination Movers and The Wiggles. Each concert is free with the purchase of that date's game ticket, and it will begin following the conclusion of that date's game. In addition to their game tickets, fans can watch the various acts from the field by purchasing field access passes available at raysbaseball.com/concerts.
