The Washington Nationals have split their first eight meetings with the Philadelphia Phillies during the 2021 MLB season, but enjoyed success in their most recent trip to the City of Brotherly Love. Washington posted a pair of one-run victories to sweep the two-game set last month, scoring a total of 16 runs in the process. The Nationals have totaled just nine during their current four-game losing streak, which they look to halt Monday as they visit the National League East rival Phillies for the opener of a four-game series. Should you expect Philadelphia to keep Washington reeling, or is there value on the Nationals to end their slide and bring a return on the money line?

The latest MLB odds for Monday from William Hill Sportsbook list the Phillies at -125 (risk $125 to win $100) against the Nationals. Other MLB lines of note include the Los Angeles Angels at -145 against the Colorado Rockies and the Chicago Cubs at -135 versus the Cincinnati Reds.

Top MLB picks for Monday

The model likes the Chicago White Sox at -121 on the money line against the Kansas City Royals. Chicago ended its three-game losing streak Sunday with a 3-1 triumph at Milwaukee, as All-Star Lance Lynn yielded one run over six innings while helping his own cause with a two-run single. On Monday, the White Sox will only need a solid performance on the mound from Dallas Keuchel, who has provided plenty of those of late. The 33-year-old left-hander has allowed fewer than three runs in five of his last seven starts, working at least six innings in four of those outings.

The former AL Cy Young Award winner gave up two runs over five frames in a no-decision against Minnesota on Tuesday after yielding one run in seven innings of a victory at Baltimore in his previous turn. Keuchel has yet to face the Royals this season but has been quite successful against the club over his career. The veteran allowed two runs over 10.1 frames in two outings -- both victories -- last season and has posted a 6-1 record and 2.48 ERA in 11 overall starts versus Kansas City.
