For the second straight year, the Rangers have had trouble finding a closer early in the season. In 2016, Shawn Tolleson blew four saves in his first 15 opportunities, before the team replaced him with Sam Dyson. This year, Dyson in turn has collapsed — he had a disastrous debut, and when he returned from a DL stint, Texas had yanked him from the closer role.

Despite the difficulties, the Rangers don’t lack relief pitchers. Matt Bush has held down the ninth inning admirably in Dyson’s absence; since the beginning of the 2016 season, he’s been one of the best relievers in the American League. Behind him, another hurler lies waiting, perhaps even better. The sample is small, as is usually the case with April baseball, but this 23-year-old righty has looked untouchable to start the season.
If you read BtBS, there’s a good chance you’re familiar with cFIP; it’s the metric Baseball Prospectus uses to appraise a pitcher’s all-around ability. It’s sort of like FIP, but with more context (hence the name), in the form of adjustments for specific ballparks, opponents, catchers, and the like. By this metric, these are the best pitchers in baseball:
Best pitchers by cFIP, 2017
Rank | Player | Innings | cFIP |
---|---|---|---|
Rank | Player | Innings | cFIP |
1 | Chris Devenski | 16.2 | 54 |
2 | Jose Leclerc | 10.0 | 56 |
3 | Craig Kimbrel | 10.1 | 63 |
4 | Chris Sale | 37.2 | 64 |
5 | Cody Allen | 10.0 | 65 |
6 | Noah Syndergaard | 26.0 | 67 |
7 | Blake Parker | 10.2 | 70 |
8 | Justin Wilson | 10.2 | 71 |
9 | Luis Severino | 27.0 | 72 |
10 | Andrew Miller | 11.2 | 72 |
This list has a few surprising names on it — BtBS has already covered Chris Devenski, and I don’t even know who Blake Parker is — but the guy leading the way might be the biggest surprise of all. Where the hell did Jose Leclerc come from?
Last year, Leclerc was a middling relief prospect, who negated a 28.8 percent strikeout rate with a 14.0 percent walk rate. FanGraphs put him 18th in the Rangers system; Baseball Prospectus omitted him entirely. He was a filler arm, someone with velocity who would never be able to put it all together.
Come 2017, Leclerc has pitched 10 innings, striking out 16 of the batters he’s faced while walking one. Thanks to that, and some weak contact, he’s put up a 0.90 ERA and 0.11 FIP, placing among the major-league leaders in each. From humble beginnings, Leclerc has ascended to the ranks of the elite — and it’s not hard to see why.
For one thing, Leclerc has a deep arsenal. He can come at a hitter with any of six pitches:
Leclerc arsenal
Pitch Type | Fourseam | Sinker | Cutter | Slider | Curve | Change |
---|---|---|---|---|---|---|
Pitch Type | Fourseam | Sinker | Cutter | Slider | Curve | Change |
Frequency | 37.2% | 11.6% | 16.5% | 24.8% | 4.1% | 5.8% |
We’ll start with Leclerc’s primary pitch. The four-seam fastball has a pretty nasty bite — Leclerc has averaged 96.0 mph on it, but he can ramp it up to 97, as seen here:
Compared to an average right-handed reliever, Leclerc gets a little less run (-3.0 inches on average) and a lot more rise (9.7 inches) on his four-seamer. The result is a hard, straight ‘riseball’ that tends to eat up hitters, who either whiff or make weak contact.
Those two pitches in the middle of the table, though — they’re the money makers. Leclerc’s slider has gone for a swinging strike 33.3 percent of the time he’s thrown it; his cutter has a whiff rate of 50 percent even. The former ended up retiring Mike Trout after he flailed at the heater:
FanGraphs classifies the two as one pitch; think of it as a ‘slutter’. They aren’t too dissimilar in terms of velocity and movement:
Leclerc slider and cutter
Pitch Type | Leclerc cutter | MLB cutter | Leclerc slider | MLB slider |
---|---|---|---|---|
Pitch Type | Leclerc cutter | MLB cutter | Leclerc slider | MLB slider |
Velo | 86.9 | 89.5 | 83.2 | 85.4 |
HMov | 2.3 | 1.0 | 3.4 | 2.9 |
VMov | 4.0 | 5.4 | 2.0 | 1.5 |
Neither one travels faster than the average, which may work to their advantage; with a greater velocity differential between pitches, Leclerc can keep hitters guessing.
More importantly, he’s established a clear trend with his pitches (borne out in the GIFs above). The fastball is for attacking hitters, while the slider/cutter are for putting them away:

A full 50 percent of Leclerc’s sliders and cutters have been down-and-away to righties. That’s the 22nd-most in the majors among fellow right-handers.
Now, this brings us to the catch with Leclerc: He has some trouble with lefties. Thus far in 2017, he’s struck out only two of the 14 left-handed hitters he’s faced, tallying a grand total of two swinging strikes in 51 pitches to southpaws. Even if he can’t figure out lefties, though, he’ll certainly make a living against righties — they’ve struck out more than 60 percent of the times he's faced them. If matched up well, Leclerc can remain a dominant bullpen arm.
Bush looks like the de facto closer for now, even if Jeff Banister won’t refer to him as such. Leclerc and his elite cFIP will live in the eighth inning for now, mowing down all the righties he sees. The fastball/breaking ball one-two punch has made many a great reliever; Dyson lived on it for a couple of years, and now Leclerc has discovered it as well. Even if his excellence doesn’t last forever, the Rangers will enjoy whatever they can get from Leclerc.
