2020 Fantasy Outlook
Armed with a blazing fastball that can hit triple digits and a plus slider that registers plenty of swings-and-misses, Rainey stormed onto the scene with a 34.6 K% in his first season with the Nationals. The gaudy strikeout total was accompanied by a less-impressive 3.91 ERA (4.37 FIP) largely due to the right-hander's struggles with his command. Rainey's 17.8 BB% ranked dead last in the league among pitchers who threw 40 or more innings and wasn't far off from the elevated rates he has surrendered in the minors. Whether Rainey can tame his control issues to a tolerable level could ultimately determine his future role in the big leagues. His fastball-slider combination certainly resembles that of a closer, and last season's .194 xBA emphasizes how dominant Rainey has the potential to be. He isn't ready for a ninth-inning role just yet, but he could be groomed for that responsibility in the near future. Read Past Outlooks

Remains in middle-relief mix
PWashington Nationals
March 14, 2020
Rainey has posted a 3.38 ERA, 1.31 WHIP and 3:3 K:BB through 5.1 spring innings.
ANALYSIS
While the right-hander hasn't been dominant, he also has yet to allow a home run this spring, an encouraging note after he surrendered 10 long balls in his first 55.1 big-league innings over the last two years. Rainey is expected to open the regular season in middle relief for the Nats, but his high-90s fastball and sharp slider could allow him to work his way into a late-inning role if his command takes a step forward.

Stat Review

* 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.

Mound Musings: The Phones Are Ringing

Brad Johnson looks at the pitching desires of playoff contenders, including the Braves, who, in need of a closer, could be looking at Giants reliever Will Smith.
2019 Fantasy Outlook
Why would the Nationals trade an established starter in Tanner Roark to the Reds for a guy who allowed 19 runs in his first seven MLB innings? For one thing, Rainey can rush it up there in triple-digit fashion though he needs significant improvement in the control department. Rainey posted an impressive 2.65 ERA and 1.18 WHIP for Triple-A Louisville, fanning 65 in 51 innings, albeit with 35 free passes. Aside from honing control, Rainey needs to develop an offspeed offering. He throws a slider and change, but both are within 10 mph of his heater, making it easier to sit dead red. While Rainey has late-inning potential, he'll first have to earn a spot in the Nationals' restocked bullpen, starting out in low-leverage scenarios. Monitor his walk rate in the spring and early part of the season. If he can exhibit better control, he'll quickly ascend the ladder.
