Washington Nationals general manager Mike Rizzo appears to have his eye on a pair of St. Louis Cardinals.

The Nationals have reportedly scouted both Cardinals outfielder Tommy Pham and reliever Trevor Rosenthal, sources told MLB Network's Jon Morosi.

Capable of playing in any of the three outfield positions, Pham is having a career year in his fourth major-league season. The 29-year-old is slashing .312/.400/.534 (142 OPS+) in 253 at-bats to go along with 14 home runs while contributing 3.2 WAR, per Fangraphs.

Rosenthal, meanwhile, would add another experienced arm to the back end of the Nationals' bullpen, a unit the club has already attempted to upgrade via trade this month after acquiring both Ryan Madson and Sean Doolittle from the Oakland Athletics on July 16.

The 27-year-old Rosenthal has posted a 3.69 ERA in 39 innings this season for St. Louis, though he does also have experience as a closer, a role the Nationals have struggled to permanently fill in 2017.

Though he was replaced as the Cardinals' ninth-inning man in 2016 by Seung Hwan Oh, Rosenthal converted 93 of 102 saves from 2014-15 while posting a combined 2.65 ERA over 139 innings.
