His opponent quality (OppQual) is 8.5, so he’s thrown against some good competition. He got his first save of the spring against the Chicago Cubs last night, allowing one hit that plated an inherited runner along with a walk but no strikeouts. The glaring concern continues to be the high walk rate - four walks to just six strikeouts. Since Peralta’s walks were also plentiful last year, are we in for another spotty season from the Royals (potential) closer?Since it is inopportune at this point to make weighty assessments on how Peralta will attack hitters this season, we can take a look at what issues arose in 2018 and see if Peralta is able to correct them going forward.To suppress any initial doom and gloom, Peralta has some things working for him. His slider is pretty good and he increased his changeup use. The off-speed pitch ended up being his best last year according to Pitch Info Pitch Values (2.9 wCH).The changeup also drew Peralta’s highest swing rate (61%) and also produced the most whiffs of his four pitches (19%). To give a little perspective, Peralta threw the pitch just 11% of the time and primarily used it against lefties. I’d love to see him use it more this year.Peralta’s primary pitch was the fastball, of which he equally threw the two-seam/sinker and four-seam variety. Below is an example of how the slider and changeup work with Peralta’s fastball.Peralta’s fastball averages around 97 MPH. Being able to throw that hard immediately puts him at an advantage over other pitchers. On the flipside, Peralta had a really low spin rate on his four-seam last year. His 2100 RPM was on the lower end of baseball last year (minimum 300 pitches). Somewhere around 2300 RPM is the league average.Low spin rate on a (four-seam) fastball can be a issue depending on what the goal of the pitch is. In this chart from a Driveline Baseball research article published earlier this year plots whiff rate by spin rate and velocity. Keep in mind Peralta’s figures when inspecting.Notice that at 96-98 MPH, a spin rate in the 19-2100 rage should yield a 10% whiff rate. Yet in 2018, Peralta caused hitters to miss his fastball at a rate of only 5%. What’s more, when hitters did make contact on the four-seam, they were pretty successful (.333 BAA). The two-seam/sinker was only a slightly different story (.313 BAA).To be fair, the BABIP on those pitches were high [url=http://www.chicagocubsteamshop.com/authentic-ron-santo-jersey]Ron Santo Jersey[/url] , indicating that perhaps Peralta was the victim of some bad defensive luck. The Royals defense, in terms of defensive runs saved, deems them league-average.His xwOBA (expected wOBA) vs. his actual wOBA creates a modest argument against the luck assessment. The difference between what was expected and his actual wOBA on the fastball was about 21 points lower. Disparities of 100 points or more would be more likely to indicate regression (good or bad) the next year. We could say, for the most part, that he got what he deserved (for lack of a better phrase) with the pitch.So was the issue with location? Below maps out where Peralta typically went with his fastballs followed by average exit velocity by zone.This data coincides with the fact that Peralta’s overall hard-hit rate (Hard%) last year leaped nearly 15% above his career average of 30%. Peralta kept his fastball out of the zone around 53% of the time, much higher than the league average of 46%, which was likely for good reason. You can see that when the fastball did end up in the zone, it was walloped. What’s more is hitters whiffed just twice on fastballs in the strike zone. With a high-90s fastball, that’s hard to understand. So was it sequencing? I can’t see how. Peralta did a good job mixing his pitches last year. And while the two-seam/sinker saw some temporary improvement, his fastballs got worse as the season went on. You can also see a degraded performance correlation when looking at his fastball whiff trends.While this all sounds pretty bad, we shouldn’t come down on Peralta too hard. The former starting pitcher gave us an incredibly small sample size in 2018 so its hard to glean future value out of what he did. It’s easy to say all Peralta has to do is increase his spin rate on the four-seam. Improving spin rate directly correlates with more swing and miss stuff as evidenced by the whiff rate chart from Driveline. I have to wonder if that adjustment would actually improve the pitch for him.Peralta’s overall command isn’t great. According to Baseball Prospectus’ command metric (CMD), he’s ranked well below average with a score of 40. So was his delivery erratic? There doesn’t seem to be anything mechanically off as his release point spread is minimal. If nothing else, his arm slot got progressively lower through the year.So the issue might in fact be lack of command and control of the strike zone. Let’s look at a couple of examples. Here’s a fastball that catcher Salvator Perez wanted low. Peralta (we assume) mistakenly threw it high and, well...From the screenshot, we see where Perez’s glove was initially positioned.In the next example, Peralta wasn’t off by much but still hung the pitch. Luckily for him [url=http://www.chicagocubsteamshop.com/authentic-ernie-banks-jersey]http://www.chicagocubsteamshop.com/authentic-david-ross-jersey[/url] , the Detroit Tigers’ Jeimer Candelario barely missed rocking the pitch and drove the ball into the ground for a double play.Below might be the worst example of Peralta missing his spot. Again, he got a break because the Tigers’ Victor Martinez missed tying the game by just barely swinging under the 98 MPH fastball.Another look at the desired location for the pitch, which ended up nowhere near Perez expected it.Peralta’s best bet is to ditch the four-seam and focus on the two-seam/sinker. Unless he can make changes to improve his spin rate (which isn’t likely), he’s much better off using a two-seam/sinker. It has better movement and is thrown harder in relation to others who throw the pitch, even more so that his four-seam. Peralta’s whiff rate on the pitch is much better than league average. It induces a lot of ground balls and doesn’t come with the slugging risks that the four-seam does. Peralta seems confident in what’s come in 2019. In an article by Lynn Worthy from the Kansas City Star, Peralta spoke on his perspective as a late-inning reliever:That mindset will be important because, in terms of leverage, Peralta seems to excel when the pressure is on. That’s exactly what you want from a setup/closer. If he manages to stay in either of those roles, I’d really like to see his K/9 reach at least 10-12 (he was at a little over 9 in 2018) and that walk rate has to come down. By removing the four-seam and replacing it with a seemingly effective changeup along with his knockout slider, we could reasonably expect an uptick in performance and a much more comfortable pitcher. If his fastball control can be harnessed (which may give him more confidence in his repertoire), Peralta could fast become one of the best closers, let alone relievers, in baseball. ST. LOUIS (AP) — Cardinals pitcher John Gant got a new label from teammate Jose Martinez — power hitter.Harrison Bader and Gant hit back-to-back home runs, Gant pitched into the sixth inning and St. Louis beat the Pittsburgh Pirates 5-0 on Thursday night.“You hit one, you’re lucky,” Martinez said of Gant’s second blast of the season. “You hit a second one [url=http://www.chicagocubsteamshop.com/authentic-ryne-sandberg-jersey]Ryne Sandberg Jersey[/url] , you’re a power hitter.”The Cardinals have won 17 of 21 and took their tenth consecutive series, their longest series winning streak since 2009, when they also won ten in a row.“It’s an important thing,” Cardinals manager Mike Shildt said. “We want to get better as the game goes and we want to get better as the series goes. And if you take care of the series, the rest of it just falls into place.”Gant (6-5) pitched out of a bases-loaded situation in the first and a two-on, no-out jam in the third to win for the third time in his last four tries. He struck out six in 5 2/3 innings and has allowed one earned run in his last 12 2/3 innings.“It was a great team win, a great series win,” Gant said. “Another series win, and we’re going to try to keep on chugging.”Pirates starter Joe Musgrove (5-8) opened the game with 21 consecutive strikes, a first in the majors since pitch tracking began in 1988, according to Stats. That control didn’t do him much good, though. He gave up five runs in six innings.“I came out sharp but I didn’t keep my foot on the gas,” Musgrove said. “I didn’t keep going. That’s got to be done against a good lineup like that.”Musgrove’s strike streak ended with a first-pitch ball to Bader in the third, and two pitches later, Bader went deep to left. Gant then homered on a 2-1 pitch, giving St. Louis consecutive home runs for the seventh time this season.“I’m just trying to make contact and contact was made tonight [url=http://www.chicagocubsteamshop.com/authentic-billy-williams-jersey]Billy Williams Jersey[/url] ,” Gant said.Gant tied Miles Mikolas for most home runs among St. Louis pitchers this season. After starting his career 0 for 30, Gant has homered twice in his last six at-bats. He is the third pitcher in the expansion era to have his first two career hits as home runs.Shildt said Gant put in a gutty performance.“He was making pitches,” Shildt said. “He missed a few spots and the guys made some plays, but John’s a really good competitor, he’s a mentally tough guy, so he was really just able to compete with what he had and used all his pitches.”Martinez singled and scored in the fourth and drove in two more with a single in the fifth to give the Cardinals a 5-0 lead. Martinez has hit safely in 20 of 25 games in August and has a team-high 18 multi-RBI games.“He was actually trying to mix in some pitches and he was throwing some different pitches than we were expecting,” Martinez said of Musgrove. “We just had to make the adjustments.”Pittsburgh lost for the seventh time in its last nine games. The Pirates stranded 12 runners and went 0 for 9 with runners in scoring position.“There was hard contact,” Pirates manager Clint Hurdle said. “It’s not fair. There’s times when it’s not fair. You hit hard balls, you hit them right at people but you’ve just got to play man.”FACE IN THE CROWDSt. Louis Blues star Vladimir Tarasenko signed autographs on the field before the game.TRAINING ROOMCardinals: OF Marcell Ozuna (right shoulder inflammation) took batting practice Thursday and is on track to return from the 10-day disabled list when eligible on Sept. 1.UP NEXTPirates: RHP Jameson Taillon (10-9, 3.49 ERA) kicks off a three-game series on the road against the Atlanta Braves and RHP Anibal Sanchez (6-5, 3.05 ERA).
