According to Passan, the players headed to Washington are an infielder and a reliever. USA TODAY reported similarly, citing an official with "direct knowledge of the negotiations."
Detwiler, 28, has spent his entire seven-year career with the Nationals. In that time, he has recorded an ERA of 3.82, going 20-32 in 132 games and 285 strikeouts in 471 innings.
Detwiler moved to Washington's bullpen last season, according to USA TODAY. Over 47 games, he went 2-3 and pitched 63 innings, earning a 4.00 ERA. He was left off the roster for the Nationals' National League division series against the San Francisco Giants in October.
The Rangers finished last season 67-85 and fifth in the AL West.
