Javy Guerra

One of a series of relievers acquired mid-season by Washington in 2019 to bolster their beleaguered bullpen, Guerra was largely underwhelming in his time with the club. In 40 games with the Nationals, the veteran posted a 4.86 ERA (4.50 FIP) and allowed nine home runs in 53.2 innings. Between Toronto and Washington, Guerra gave up more fly balls than grounders for the first time in his career (0.82 GB/FB) and, accordingly, was pounded for a career-worst 1.33 HR/9. The right-hander did improve in some areas -- both his 5.9 BB% and 19.9 K% continued a recent trend in a positive direction -- and his .255 xBA was his best mark in the past five seasons. That could be something to build upon, but Guerra is entering his age-34 campaign and is not guaranteed a roster spot after signing a minor-league deal in the offseason. Even if he does stick in the Nats' bullpen, he isn't worth consideration in fantasy leagues.
