June 21, 2019
Guerra (1-0) struck out two in a perfect sixth inning Thursday to pick up his first win of the season in a 7-4 victory over the Phillies.
The right-hander has been a solid part of the recent turnaround for the Nats' bullpen, posting a 2.35 ERA, 1.04 WHIP and 12:3 K:BB through 15.1 innings since being claimed off waivers from the Blue Jays. Guerra likely won't see much high-leverage work, limiting his fantasy appeal, but he's capable of providing useful ratios in deep formats.

Stat Review
How does Javy Guerra compare to other relievers?
This section compares his stats with all relief pitcher seasons from the previous three seasons (minimum 30 innings)*. The bar represents the player's percentile rank. For example, if the bar is halfway across, then the player falls into the 50th percentile for that stat and it would be considered average.

* Exit Velocity, Barrels/BBE %, Balls Hit 95+ MPH %, and Spin Rate are benchmarked against this season's data (min 20 IP). See here for more exit velocity/barrels stats plus an explanation of current limitations with that data set.

  • K/9
    Average strikeouts per nine innings.

Past Fantasy Outlooks
The White Sox nabbed Guerra off waivers in March, added him to the active roster in May, and he served in an unimportant middle relief role for the rest of the year. His average fastball velocity was only down a few ticks from his rookie season, when he closed for the Dodgers, and he has added an effective new cutter to his repertoire since joining the Sox's pitching staff. However, his strikeout (7.4 K/9) and walk rates (3.9 BB/9) are both unimpressive for his middle relief standing, and the addition of David Robertson via free agency all but guarantees that Guerra won't be tasked with any save situations in 2015.
With a 5.84 ERA at the time, Guerra was removed from the closer role in favor of Kenley Jansen on May 7 and he failed to notch a single save the rest of the season. However, Guerra responded by posting a 1.38 ERA in 32.2 innings the rest of the way after losing his closer role, but did miss some time with knee and oblique injuries. He managed to add to his medical chart by undergoing a minor shoulder procedure in November, but all signs point to him being 100 percent well before he's due to report to spring training. Expect Guerra back in a setup role in 2013, though he's probably fourth in the pecking order for saves.
When Jonathan Broxton went down with an injury and Hong-Chih Kuo and Vicente Padilla had their own issues, it was ultimately Guerra who stepped up and filled the closer role for the Dodgers. In 46.2 innings, Guerra saved 21 games with a 2.31 ERA and 1.179 WHIP. His 7.33 K/9IP and 3.47 BB/9IP were merely average, so Guerra likely won't be guaranteed the closer job headed into spring training. To maintain that role, he'll have to beat out Kenley Jansen, who seemingly struck out every batter he faced last year (actually a 16.10 K/9IP). Regardless, Guerra will have an important role in a Broxton-less pen this year.
Guerra finished a combined 6-2 with a 2.60 ERA in 51 relief appearances between Low-A Great Lakes and Double-A Chattanooga last season, numbers good enough for the Dodgers to add him to the 40-man roster this winter. He could compete for a bullpen spot this spring, but will have limited fantasy value.
