Featured Pitch: Luis Avilan’s Curve
What Happened Yesterday
Yesterday, left-hander Luis Avilan pitched two perfect innings of relief for Atlanta in the 6-2 victory over the New York Nationals (box).

What Has Happened More Generally
More generally, Avilan, who pitched almost exclusively as a starter at Double-A Mississippi, has been an entirely proficient member of the Braves bullpen for two-plus months. To wit: 35.0 IP, 23.2% K, 7.3% BB, 45.7% GB, 3.15 SIERA, 90 xFIP-, 0.6 WAR, 5 SD, 1 MD.

How Avilan Has Done That
Avilan’s success is based largely on his curveball, on which pitch he has posted a 19.0% swinging-strike rate (relative to a league average of ca. 11%, according to work by Harry Pavlidis). Avilan’s curve has been worth close to four runs above average for every 100 he’s thrown.

Leaderboard: Curves by Run Value
Here are the top-five leaders by run value above average among pitchers who’ve thrown at least 50 curveballs this season (R/100 is runs above average for every 100 curves thrown):

Name Team IP Pitches CU% Tot. CU Runs R/100
Jesse Crain White Sox 47.0 838 6.0% 50 3.1 6.2
Scott Atchison Red Sox 50.2 685 14.9% 102 4.6 4.5
Brett Anderson Athletics 35.0 527 11.1% 58 2.4 4.2
Sam LeCure Reds 55.2 919 14.5% 133 5.3 4.0
Luis Avilan Braves 33.0 500 18.6% 93 3.4 3.7

What One Learns
One learns from this footage that the break of Avilan’s curveball isn’t particularly devastating, but also that the pitch features considerable horizontal movement (a full standard deviation more than league average for a left-hander, it turns out) and is likely quite effective against left-handed batters for that reason. (Indeed, according to PITCHf/x data from Texas Leaguers, Avilan throws the curve ca 29% to left-handed batters and just 11% to right-handed ones.)

Today’s Notable Games
Boston at New York AL | 19:05 ET
In the event that the reader had ever entertained notions of visiting Barf City, watching this game will provide a direct route to it.

Readers’ Preferred Broadcast: Boston Radio.

Baltimore at Tampa Bay | 19:10 ET ***MLB.TV Free Game***
Playoff Implications™ abound. With three games remaining the upstart Orioles — who are actually among September’s best teams by run differential and WAR — are tied atop the AL East with the despotic Yankees.

Readers’ Preferred Broadcast: Baltimore Radio.

New York NL at Miami | 19:10 ET
Right-hander Jeurys Familia, ranked third among Mets prospects on Marc Hulet’s preseason top-15 list, makes his first major-league start. The 22-year-old has pitched well in seven relief appearances so far (8.1 IP, 91 xFIP, 0.1), while sitting at ca 96 mph with his fastball. This game also features the benefit of Miami’s excellent, straight-on center-field camera.

Readers’ Preferred Broadcast: New York NL Television.
