Morning Mound Visit: Jason Castro heads back to Houston

Castro returns to Astros; BP’s Top 101; JT Realmuto’s market heating up

Jeffrey Paternostro, Jarrett Seidler, and Keanan Lamb | Baseball Prospectus $: Baseball Prospectus unveiled their Top 101 prospects for 2021. It’s no surprise that Tampa Bay’s Wander Franco topped the list. Other takeaways: The Mariners landed six prospects on the list including two in the Top 10. The Dodgers have four players on the list, but their highest-ranked prospect is Josiah Gray at 55.

Ben Clemens | FanGraphs: After watching the Blue Jays sign George Springer, the Astros have since re-signed Michael Brantley and now they’ve brought back old friend Jason Castro. Castro has never been known for his hitting prowess, but he isn’t without his upside.

Kris Willis | Talking Chop: Atlanta is “circling on” J.T. Realmuto, the best remaining position player on the free agent market. The report came from FanSided’s Robert Murray who also mentioned that teams on the west coast are interested as well.
