PHOENIX – Lane Thomas joined the Nationals on the day the organization began to tear down its championship roster and start a massive roster rebuild. Three years later, with the franchise believing its much closer to winning again, he’s heading to another organization right in the thick of a pennant race.

The Nats traded Thomas to the Guardians this afternoon for three prospects, including highly touted 19-year-old left-hander Alex Clemmey, opting to deal one of their coveted regulars who still had another season of club control about 24 hours before Tuesday’s trade deadline.

Along with Clemmey, Cleveland’s 2023 second-round pick and current No. 7 prospect, the Nationals receive 19-year-old infielder Rafael Ramirez Jr. and 23-year-old infielder Jose Tena, who has big league experience and joins the 40-man roster.

It’s a significant haul for the 28-year-old Thomas, who got off to a slow start this season but entered the day batting .253 with eight homers, 40 RBIs, 28 stolen bases and a .738 OPS in 77 games. The outfielder spent the last few days trying to block out trade rumors but wasn’t caught completely off-guard when he was called into manager Davey Martinez’s office at Chase Field about three hours before tonight’s series opener against the Diamondbacks.

“It’s always a little bit of a shock, even when you know they’re looking to do something like that,” Thomas said. “I’ve been in this situation before, so I feel like that makes it a little bit easier. My wife has dealt with it, too. I think we’re ready to go help another team.”
