The Pittsburgh Pirates are holding their annual winter mini-camp at Pirate City this week. The four-day event is voluntary for any player on the 40-man roster and also includes non-roster invites to Spring Training. Tim Williams is providing live coverage of the camp. Our summary from day one includes nine videos, with a focus on Ke’Bryan Hayes, Cole Tucker and Kevin Newman.

The players who showed up yesterday include: Chris Archer, Edgar Santana, Will Craig, Gregory Polanco, Luis Escobar, Eduardo Vera, Jesus Liranzo, Brandon Waddell, Alex McRae, Geoff Hartlieb, Blake Weiman, JT Brubaker, Nick Burdi, Steven Brault, Joe Musgrove, Cole Tucker, Kevin Newman, Steven Baron, Richard Rodriguez, Christian Kelley, Patrick Kivlehan, Ke’Bryan Hayes, Arden Pabst, Jason Martin, Jason Delay and Bryan Reynolds. There are also lockers set up for Tyler Eppler and Chad Kuhl, plus other players could show up for a day or two, though no one is required to be there.

We will post updates in this article throughout the morning and early afternoon so check back often.
