Griffin Jax (SP, MIN) - Week 21 Waiver Wire Pickups

August 15, 2021

Griffin Jax is a fantasy baseball waiver wire pickup for Week 21 of the 2021 MLB season. Consider adding the SP if he's a free agent in your leagues.

BALLER MOVE: Add in leagues of 14+ teams

ROSTERED IN: 2% of leagues

ANALYSIS: Don't pay too much attention to Jax's current 5.45 ERA and 1.211 WHIP. After getting off to a rough start this year out of the bullpen followed by a disastrous first start, Jax has been pitching very well over his last four starts, going 2-0 with a 2.66 ERA, 0.787 WHIP and 23.1 percent strikeout rate over 20 1/3 innings of work. He'll open up the week against Cleveland, as they have averaged 3.7 runs per game while slashing .251/.306/.382 over their last 10 games. It will be his first time facing them since joining the rotation, and he'll be helped by the fact that they have been hitting worse on the road (.227/.290/.388) than at home (.237/.307/.410). He'll then close out the week in New York, facing a red-hot Yankees squad that is slashing .272/.351/.439 while averaging 6.1 runs per game over their last 10 games. Jax should have a decent matchup with the Yankees though, as they are both hitting worse against right-handed pitching (.228/.318/.379) and hitting worse at home (.233/.328/.396).

Jax is a pitcher on the rise, and likely will be one of the best guys to choose in deeper formats this week.. Managers should pick him up in most formats to use him as a streamer this week, and if he puts up the results I expect out of him, go ahead and keep him rostered full time as he should be a good pitcher to have down the stretch into the playoffs.
