How Braves Rookie Spencer Strider used a two-story combination to become one of the most dominant starters in MLB

The Atlanta BravesWorld Champion, will go into the playoffs. The question the Braves will have to answer for the next two weeks is whether they will win the Eastern National League title for the fifth time in a row, or whether they will have to settle for an unexpected niche. Wherever the Braves end up, they can attribute their success this season in part to the emergence of right-wing rookie Spencer Strider.

Strider, 23, was courting the Philadelphia Phillies on Sunday, keeping them off the board in the sixth inning. He succumbed to Alec Boehm, who thwarted his hitting attempt, but ended the afternoon with the following line: six innings, one run on one stroke, three walks, 10 strokes. In other words, it was another dominant start from someone who had recently accumulated his stake.

It’s hard to remember now, but Strider wasn’t shown in a meaningful way early in the season. He didn’t make his debut until May 30, his twelfth appearance of the year. His first 11 trips included a lot of low-influence appointments. Since moving into the spin, Strider has become a pivotal member of the Braves shooter through production as one of the game’s top entry-level players.

Heading into Sunday, Strider has accumulated a 2.84 ERA and 5.00 strike-to-walk ratio in 19 starts, giving it scores similar to the San Francisco Giants Left Carlos Rodon, major league captain for Wins Above Replacement, according to FanGraphs calculations. Check out how Strider (only as a beginner) stacked up against Rodon before Sunday’s game:











The Rodón comparison is useful in other words since he and Strider are both beginners on the field. While Rodon cuts and slips the fast ball 92.6 percent of the time, Strider takes it a step further: His use of the fast ball and slider accounts for 95 percent of his playing fields. Strider has managed to succeed with a predictable formula that speaks to bigger changes across the leagueIn addition to the occasional quality.

In fact, Strider might have the best fastball in the majors. His geyser features an above average breakout horizontally and vertically, and his average speed of 98.2 mph ranks third among pitchers with no fewer than 500 throws this season, behind Baltimore Orioles Closest Felix Bautista and Cincinnati Reds Hunter Green flamethrower. Believe it or not, the fast strider ball game plays much hotter than this number indicates. Despite being listed at a height of 6 feet, it is able to descend quite far down the hill. Its span, or the distance from the rubber band to its point of release, is closer to seven feet. Going too much distance enables his fastball to run about a mph faster as a result.

Strider’s Fastball takes advantage of his firing point in other ways, too. His stature and depth of release create a flat angle from his hand to the top of the area, creating an optical illusion for hitters to solve. They did not succeed. Strider has forced more than 37 percent of swings against fastball in the top third of the area this season. The league average, for reference, is 29 percent.

Meanwhile, the Strider slider is attached to New York Mets ace Jacob deGrom’s for the highest whiff rate of its kind. If there’s a flaw on the court, it’s that hitters don’t swing the Strider slider (46.7 percent) nearly as well as they do in DeGrom’s (63.5 percent). The opponent’s selectivity is a product, in part, of Strider’s tendency to throw his slider into non-competitive positions: he ranks 12th in that regard. Obviously, the location of his slider did not affect his ability to thrive; Still, it gives him potential room for improvement he can work in this winter.

Before Strider thinks too much about his off-season to-do list, he’ll need to focus on finishing the season strong to help the brave’s hopes of repeating as champions. He’s already in uncharted waters: his 131 roles represent a new career level, as well as the first time in his life that he’s crossed the three-digit threshold. Strider looks no worse for wear at this point – even before Sunday’s game, he had opened September with a 16-match strike against Colorado Rockies – but it is worth watching if and how the brave reduce his workload.

After all, Strider climbed from a fourth round to a major part of the Braves rotation by short order. If he can continue with this, he will also find himself as a key figure in the annual NL Cy Young Award talks as well.
