Rates & Barrels: A show about Baseball

Several presentations and tools from Saberseminar have us thinking about baseball in different ways. Eno, Trevor, and DVR share a few takeaways and threads to pull on in the future, including the impact of high pitch count innings, biomechanics, and more. Plus, they discuss an impressive tool -- Open Command -- and look at some of the biggest differences across pitchers compared to Location+, and they revisit a previous talk about arm angle and it's relationship to injury, especially when a high arm-angle pitcher utilizes a sweeper.

The Boston Red Sox have gone from one of MLB's biggest disappointments to a legitimate September contender. DVR, Eno and Britt Ghiroli discuss Boston's remarkable turnaround, whether Craig Breslow's changes actually fixed something within the organization and whether the Red Sox should now be viewed as a legitimate World Series threat.

First, Ketel Marte returns to the Diamondbacks following a 13-game absence. DVR, Eno and Britt discuss the reaction in Arizona, Torey Lovullo's handling of the situation and what the latest chapter could mean for Marte's long-term future with the D-backs.

Then it's time for a few September surprises. Aaron Nola put together a strong August after struggling for much of the season, Rafael Devers reached 30 home runs for the fifth time in his career and Alex Bregman's second-half power surge has quietly put him among MLB's home run leaders since the beginning of July.

Britt, DVR and Eno also discuss the controversy surrounding comments made on the Red Sox radio broadcast about Jazz Chisholm Jr. and the larger question it raises about the increasingly blurry line between broadcasters, reporters and fans.

Plus the Baltimore Orioles are finally back to .500. Colton Cowser's incredible catch helped Baltimore reach the mark for the first time since April, but the Orioles' improvement goes much deeper.

Finally, the conversation turns to Dodgers owner Mark Walter and the questions surrounding his broader business empire. How relevant are those financial issues to baseball, and how much of the Dodgers'

MLB's player development continues to change. DVR and Eno take the show on the road at Saber Seminar, exploring the evolution of pitching development, the next generation of hitting metrics and the new data that could change how teams evaluate players.

Former MLB pitcher and current University of Oregon Director of Pitching Development Dan Straily joins the show to retrace his career through one of the most transformative eras in pitching. Straily explains how being forced to develop a changeup helped take him from Double-A to the major leagues, how the Astros recognized that his fastball played better at the top of the strike zone and how pitchers gradually gained a better understanding of pitch shapes and movement.

Then Driveline Baseball's Director of Baseball Operations Jack Lambert joins the show to explain one of the emerging frontiers in hitting analysis: bat path grades. How can bat speed, attack angle, attack direction and swing-path data help measure the value of an individual swing? And could metrics like rotational acceleration eventually tell us even more about a hitter's underlying ability?

DVR, Eno and Lambert explore whether bat-path data can eventually become hitting's answer to Stuff+, how quickly swing metrics stabilize and why this type of information could become especially valuable for evaluating amateur and minor-league hitters before traditional statistics provide enough information.

It’s Doug’s birthday, and who better to help him celebrate than his former Phillies teammate and mentee, Jimmy Rollins? This week, Doug and DVR, filling in for Jayson, sit down with Jimmy to talk about the shock of being drafted by Philadelphia, how Doug helped him get acclimated to the big leagues, what it was like playing alongside Ryan Howard, Chase Utley, and Cole Hamels, and the moment he finally knew it was time to retire.
Plus, with the playoff chase heating up, Doug and DVR each pick a team they believe in. And, of course, it wouldn’t be the show without Strange But True—a particularly rough week for Mariners pitcher Bryce Miller.
