Royals acquired Vin Mazzaro for the stuff, not the stats

9 Comments

Last night the Royals traded veteran outfielder David DeJesus to the A’s for 24-year-old starter Vin Mazzaro and pitching prospect Justin Marks.

Marks is a former third-round pick and a solid prospect, but the key to the deal from Kansas City’s point of view was clearly Mazzaro, as general manager Dayton Moore called him “a big, strong guy who our scouts feel can be a solid rotation pitcher for a number of years.”

In his article about the trade Bob Dutton of the Kansas City Star writes that Mazzaro “generally draws raves from scouts for his stuff, particularly a sinking fastball.” Similarly, “a scout” told Jeff Fletcher of AOL Fanhouse that “Mazzaro’s stuff was second only to Trevor Cahill on the A’s.”

I could quote some other examples, but hopefully you get the idea. Mazzaro is 6-foot-2 and 24 years old, scouts love his raw stuff, and the Royals think he can be an impact starter for years to come. And here’s where it gets interesting: Mazzaro’s numbers aren’t particularly impressive at all.

First and foremost he’s 10-17 with a 4.72 ERA in 214 career innings, allowing opponents to bat .290 with a .360 on-base percentage and .452 slugging percentage against him. Among the 139 pitchers who’ve thrown 200 or more innings in the past two seasons, his .812 OPS against ranks 127th.

Delving a little deeper, Mazzaro has managed just 138 strikeouts in 214 innings, which works out to 5.8 whiffs per nine innings. Among those same 139 pitchers with 200-plus innings since 2009 that ranks 94th. And for all the talk about his “sinking fastball” Mazzaro has induced fewer ground balls than the average pitcher at 41.3 percent, which ranks 97th in that group of 139. His walk rate of 3.7 per nine innings ranks 115 out of 139.

So his ERA is 4.72 despite calling a pitchers’ ballpark home, he’s allowed opponents to bat .290 with an .813 OPS, he hasn’t racked up many strikeouts or induced many ground balls, and his control has been poor. In other words, Mazzaro has struggled in basically every key area of performance and even his numbers in the minors showed similar flaws.

What he has on his side is youth and the fact that at least some scouts still think his raw stuff is very good. Moore and the Royals have already established themselves as an organization that doesn’t rely on statistical analysis and in acquiring Mazzaro as the centerpiece of a trade for one of their best players they’re definitely trusting scouts and stuff rather than numbers.

Marcus Stroman: José Bautista could ‘easily’ pitch in MLB bullpen

José Bautista hasn’t appeared in the majors since 2018 but the 39-year-old isn’t done playing just yet. Last month, we learned via a report from ESPN’s Jeff Passan that Bautista is hoping to come back as a two-way player. He spent the winter working out as a pitcher.

Bautista had also been working with former Blue Jays teammate Marcus Stroman. Back in January, Stroman tweeted, “My bro @JoeyBats19 is nasty on the mound. We been working working. All jokes aside, this man can pitch in a big league bullpen. I’ll put my word on it!”

In March, Passan added some details about Bautista, writing, “I’ve seen video of Jose Bautista throwing a bullpen session. Couldn’t tell the velocity, but one source said he can run his fastball up to 94. His slider had legitimate tilt — threw a short one and a bigger bender. @STR0 said in January he could pitch in a big league bullpen.” Stroman retweeted it, adding, “Facts!”

Stroman reiterated his feelings on Tuesday. He tweeted, “Since y’all thought I wasn’t being serious when I said it the first time…my bro @JoeyBats19could EASILY pitch in a big league bullpen. Easily. Sinker, slider, and changeup are MLB ready!” Stroman attached a video of Bautista throwing a slider, in which one can hear Stroman calling the pitch “nasty.”

Stroman attached another video of Bautista throwing a glove-side sinker:

Replying to a fan, Stroman said Bautista’s body “is in better shape than 90-95% of the league.”

I am not a scout and won’t pretend to be one after watching two low-resolution videos. And Stroman’s hype is likely partially one friend attempting to uplift another. That being said, I’ve seen much worse from position players attempting to pitch. It’s a long shot, especially given his age, that Bautista will ever pitch in the majors, but it wouldn’t be surprising to see him get an opportunity to pitch in front of major league scouts.
