2021 Fantasy Outlook
Loaisiga has been up and down from the minors and the injured list for New York while serving as a spot starter/long reliever for the past three seasons. In that time, he has produced a serviceable strikeout rate, but his ratios have been subpar due to issues with walks when he is not striking guys out. He works mid-to-upper 90s with his fastball and can throw four different pitches to both righties and lefties, but perhaps a successful path forward would be to narrow down those pitches by choosing a fastball to pair with the curve and change. Seven of his nine career homers allowed have come off the fastball, and six of those off the four-seamer. Given where he must pitch his home games, not to mention the overall run environments of the AL East, perhaps accentuating his sinker could lead to improved results. Look for more swing-role work in 2021. Read Past Outlooks

September 19, 2021
Loaisiga (shoulder) is expected to throw off flat ground three straight days this week before potentially returning to mound work next weekend, Pete Caldera of The Bergen Record reports.
ANALYSIS
Loasiga resumed throwing Friday and won't throw Monday before ramping up his throwing program again. The 27-year-old could return for the final week of the regular season if he continues to progress well in his recovery.

Stat Review
How does Jonathan Loaisiga 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.
  • K/BB
    Strikeout to walk ratio.
  • K/9
    Average strikeouts per nine innings.
  • BB/9

  • Spin Rate
    Spin Rate is the rate of spin on a baseball after it is released. It is measured in revolutions per minute (rpm).
  • Balls Hit 95+ MPH

Past Fantasy Outlooks
2020
2019
Loaisiga began 2019 as the Yankees' fifth starter but pitched only two short outings before being sent down to the minors. He was then shuttled between the International League and the big club before an injury to James Paxton appeared to open the door for Loaisiga to string together a few big-league starts. Instead, the right-hander landed on the injured list himself with a strained right rotator cuff and was used as a reliever and opener when he returned to the Yankees over three months later. Loaisiga ended the regular season with a subpar 4.55 ERA over 31.2 innings, though he demonstrated a solid swing-and-miss arsenal, registering a 14.2% swinging-strike rate and 26.6 K%. The 25-year-old's fastball touches 97 mph and his spin rate of 2,424 rpm is far above average, but he may be best suited to a relief role after missing significant time with shoulder injuries each of the last two seasons.
What Loaisiga brings to the table in terms of skills is impressive, but it's tough to overlook the fact that he's now 24 and has never thrown more than 80.2 innings in a season. He appeared to be making a seamless transition to the big leagues despite skipping the Triple-A level, posting a 1.93 ERA, 1.29 WHIP and 18:8 K:BB in his first three starts with the Yankees after making the jump from Double-A Trenton. However, after his June 2 outing, Loaisiga was optioned and quickly diagnosed with right shoulder inflammation. He was shut down from throwing for close to a month, and by the time he was cleared to start a rehab assignment in mid-August, there wasn't enough time for him to build back up as a starter. It's easy to see the talent when Loaisiga is on the field as he throws 96 mph and has two other potential plus offerings (slider and changeup) and solid command, but without the innings, it's impossible to get too excited.
