26-Year-Old PitcherRP
Seattle Mariners
2020 Fantasy Outlook
Among the three prospects acquired from the Yankees for James Paxton, Swanson played the largest role for Seattle in 2019, tossing 58 innings over 27 appearances. The right-hander scuffled in eight starts, compiling a 7.56 ERA and .277 BAA, but fared much better as a reliever, posting a .191 BAA and a respectable 3.28 ERA in 19 outings. Armed with a three-pitch arsenal centered around a 93-mph fastball, Swanson demonstrated solid strikeout ability throughout his minor-league career and translated that to a decent 21.2 K% in the majors. He also excelled at limiting walks, posting a 4.9 BB% that ranked in the top 10% among pitchers who threw 50-plus innings. Swanson's primary struggle was keeping the ball in the park; he gave up a 2.6 HR/9, fifth-worst in the league. Spring training will be important for Swanson in 2020 as he could conceivably emerge as a starter or reliever or head back to the minors. Read Past Outlooks

ANALYSIS
Just recalled from the Mariners' alternate training site earlier in the day, Swanson was put right to work by manager Scott Servais, and the right-hander needed just nine pitches to get through the trio of Austin Allen, Tony Kemp and Marcus Semien. Swanson was deployed as both a starter and reliever during his rookie 2019 campaign, finishing with a 5.74 ERA and 1.17 WHIP over 27 appearances (eight starts). The 26-year-old will aim to do a better job of keeping the ball in the park -- something he never had trouble with during his minor-league career -- after surrendering a bloated 2.6 HR/9 across his 58 innings last season.

Stat Review
How does Erik Swanson 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 2019 data (min 30 IP). See here for more exit velocity/barrels stats plus an explanation of current limitations with that data set.

Collette Calls: AL Bold Predictions Mid-Year Assessment
July 18, 2019
Jason Collette looks at where his 30 bold AL predictions stand now that we're halfway through the season. Jackie Bradley Jr. is heating up in the second half again.
2019 Fantasy Outlook
Acquired from New York in the James Paxton trade, Swanson will likely use a lot of his bullets at the big-league level this upcoming season. He split his 2018 between the Yankees' Double-A and Triple-A affiliates, throwing 42.2 innings with Trenton and 72.1 frames with Scranton/Wilkes-Barre. The right-hander fared well at the highest level of the minor leagues, posting a 22.0 K-BB% and just a 17.9% line-drive rate. The numbers are less impressive when considering he was 24 years old, but the point is that he passed that last test and appears ready to graduate. Swanson is mostly a two-pitch guy (fastball/slider) and long term he may be better off as a multi-inning reliever, but it would make sense for the rebuilding Mariners to give him a chance to start in 2019. They will need rotation reinforcements when injuries inevitably hit.
