The Washington Nationals are poised to become sellers at the upcoming trade deadline as they look to build for the future. The team has identified three top trade candidates in Michael Soroka, Kyle Finnegan, and Nathaniel Lowe. Soroka, on a one-year contract, has shown promise in strikeouts despite a 4.70 ERA, making him a valuable asset for teams in need of pitching depth. Finnegan, a clear bullpen option, has maintained a strong 2.61 ERA this season; his recent performance suggests that he could fetch a solid return. Meanwhile, Lowe's recent resurgence, marked by four home runs since mid-June, highlights his potential as a reliable first-base option for contenders.
