Peña begins a rehab assignment Tuesday at Double-A Corpus Christi and could be back with the Astros within 7-10 days. He's been out since spring with a thumb issue but is the locked Astros SS once he's cleared. The 65% rostered number is misleading — for 35% of leagues he's a free claim to a starting SS in a championship-contending offense. Top-15 SS rest of season at full health. Stash now; don't wait until he's back.
