Rest-of-Season Projections
2021 Fantasy Outlook
Diaz's 2019 campaign, which saw his ERA spike from 1.96 to 5.59, served as a valuable reminder that even the best relievers in baseball aren't particularly reliable from season to season. The righty looked like he was in line for another disappointing season at the start of last year, when he allowed runs in two of his first three appearances. He allowed just three total earned runs the rest of the way, however, finishing the year with a stellar 1.75 ERA, a number he backed up with a career-high 45.5 K%. It wasn't all positive for his fantasy profile, however, as his early struggles combined with his poor 2019 season meant he was removed from the closer role for most of the year and wound up finishing with just six saves. While he may not have his manager's full faith heading into 2021, he's clearly closer material most of the time, making him a risky but very high-ceiling option during draft season.

Earns second save
Diaz allowed a hit in a scoreless ninth inning Sunday and earned a save over the Rockies.
ANALYSIS
It took Diaz a while to notch his first save, but he picked up two against Colorado this weekend. After Trevor Story knocked a two-out single, he was caught stealing to secure the game for the Mets. Diaz now owns a 3.18 ERA and 7:2 K:BB through 5.2 frames.

Diaz struck out 39% of the hitters he faced in 2019 and had a 30 K-BB%, both of which are elite rates for any relief pitcher. The problem was what happened with the other 61% of hitters he faced last season. Despite having both velocity and a strikeout rate in the 99th percentile last season, Diaz was in the second percentile of hard-hit rate and the 11th percentile of exit velocity by batters. Those type of outcomes are what drove his .281 BABIP from his record-breaking 2018 season up to .377 this past season. Both his fastball and slider had negative run values for the first time in his career, and that mainly came from his inconsistent command of both pitches. Diaz's struggles were a great reminder of two things: reliever volatility, and the difference between command and control. He threw strikes, but not where they needed to be. Elite seasons are often followed up by steps backward. Jump back in on Diaz.
