Twins Video
The Twins are off to a great start, underpinned by an excellent rotation and strong bullpen. Rotation upgrades, including a now-healthy Kenta Maeda, Tyler Mahle, and newly-acquired Pablo López have been discussed in depth. An improved catching battery, less so.
The Twins signed Christian Vázquez to a $30 million contract in December. What will his impact be defensively?
Statcast recently released additional catching metrics with new leaderboards for framing and blocking. While catching performance is some of the most complex to assess (see how a catcher calls a game), the additional data provides us with a clearer picture of how the Twins stack up defensively. Let’s dig in.
Pop Time
Let’s start with an established metric, pop time. A combination of exchange and arm-strength, this measures the time from the ball hitting the catcher's mitt to the receiving point at the center of the base they are throwing to.
Ryan Jeffers struggled to control the running game in 2022. He threw out just 18% of prospective base runners, an issue the Twins were keen to curb with Vázquez with steal attempts up due to larger bases in 2023. Vázquez has thrown out 34% of would-be base stealers in his career, about 10% above average.
Among qualified catchers (minimum 15 attempts), Vázquez has the 15th best pop time (1.94) out of 59 qualified players. Vázquez has the fourth best exchange in the majors (0.67), with an arm ranking 37th (80.4 mph). Jeffers, meanwhile, has a slow exchange (0.74, good for 42nd), and a slightly better arm than Vázquez (82.4 mph, good for 24th). This is a good illustration that arm strength is one of several factors in controlling the running game.
Headlines: Overall, Vázquez checks in as 14th best in pop time, Jeffers 32nd (out of 59). Eric Haase is the best of the rest in the AL Central, checking in at 19th in pop time. Maybe the Twins should be stealing more?
Framing
Framing is the art of receiving the ball. For catchers, there’s value to be added in receiving the ball in such a way the umpire calls borderline pitches as strikes instead of balls. The Statcast metric gives an overall output (Catcher Framing Runs) describing the number of runs a catcher saved via framing. Additionally, the metric affords us a breakdown of particular zones around the strike zone that catchers are most successful in framing. Here’s the breakdown.
Jeffers is a good, not great framer, coming in at 2 CFR (Catcher Framing Runs), good for 22nd out of 60 qualified catchers in 2022. Vázquez checks in at 1 CFR, 24th overall. Both Jeffers and Vázquez are particularly successful in framing directly above the strike zone (zone 12). The White Sox are the class of the AL Central in this category, with both Yasmani Grandal and Seby Zavala accumulating 4 CFR each in 2022.
Headlines: The Twins are good at improving catcher framing. Between 2021-2022, Gary Sanchez improved from -6 CFR (56th overall) to 1 CFR (25th overall). Jeffers and Vázquez both have a solid platform here that would make them the second best tandem in the AL Central, assuming they repeat their 2022 production.
Blocking
Blocks Above Average expresses catcher effectiveness at preventing wild pitches and passed balls. Each block converts to approximately 0.25 runs saved. Here, we see a significant discrepancy between Vázquez and Jeffers. Vázquez checks in 15th among qualified catchers at 6 BAA, Jeffers -3 (good for 51st out of 66 qualified catchers). Jeffers has a significant weakness in blocking pitches thrown to his left. For additional context, the majority of AL Central catchers are poor blockers. Mike Zunino (-8), Eric Haase (-11), Yasmani Grandal (-11), and MJ Melendez (-25) occupy four of the bottom five spots on the MLB leaderboard.
Headlines: Blocking is a tough skill. Jeffers has a clear, discernable weakness moving to his left. It will be interesting to examine how the Twins try to improve this throughout the season.
Bottom Lines: A deep dive into defensive metrics for catchers confirms some of what we already knew. Christian Vázquez is above average to good at all measurable defensive aspect of catching. Combine this with a 96 wRC+ over his last four seasons and it’s easy to see what the Twins prioritized him in free agency. As with many areas of their roster, barring injury, the Twins have one of the highest floor tandems in the American League.
What are your thought on the new catching leaderboards? How do you feel the Twins tandem stacks up against other teams in the AL Central?
