  • How Is Mike Pelfrey Doing This?


    Parker Hageman

    I warned everyone in April that this might be a real possibility.

    At that time, just several starts into the 2015 season, the analysis was smothered with caution sauce. Statistically, there were indicators abounding that things were going to go south quickly, however there seemed to be something different about this Mike Pelfrey. This Mike Pelfrey was peppering the zone, possessed improved velocity, induced weak contact, had improved his swing-and-miss capabilities, and added a second pitch.

    For various reasons Pelfrey’s ability to sustain this success was questioned. Despite the swinging strikes, he really didn’t strike anyone out. He put a ton of baserunners on but managed to wiggle out of jams by the skin of his teeth. Surely the wheels were ready to come off. And when the Detroit Tigers pounded him for 10 hits over four innings a few short weeks later, it felt as if the foreboding avalanche of regression would leave no survivors.

    But then something unexpected happened: He didn’t regress. Mike Pelfrey went back out and threw 13 innings of 10 hit, two-run ball over his next two starts. Instead, he concluded Tuesday night’s victory over the Boston Red Sox tied with Edinson Volquez with a 2.77 ERA -- the 10th best in the American League. It is especially crazy considering his expected performance figures peg him to be around 4.50.

    How has he continued to outperform performance indicators like xFIP? Nine starts is by no means an ample sample but the traits that Pelfrey demonstrated in April have rolled over into May.

    In addition to the ERA (which should not be used in gauging the quality of a pitcher’s performance so stop using it), Pelfrey has managed to keep opposing hitters away from hard contact. According to ESPN/trumedia, he maintains a well-hit average of .103 -- this time 12th best in all of baseball. BaseballSavant.com’s batted ball velocity more or less confirms this, saying Pelfrey’s batted ball velocity of 87 mph is 18th among all qualified pitchers. Tons of contact but the vast majority of it is weak.

    Pelfrey’s inclusion of the splitter has elevated his arsenal to a new level. It is lethal against left-handed hitters and has kept right-handers honest to some degree. Watch the movement it showed in his last start against Pittsburgh. This was a nasty pitch that incited a silly swing from the Pirates’ Pedro Alvarez:

    This season’s splitter has a lack of spin and that provides drag and drop. When thrown with similar arm speed as a fastball it can produce some head-shaking swings.

    Pelfrey’s current .202 batting average against lefties is 10th lowest in baseball by a right-hander -- company that includes pitching elite like Felix Hernandez, Matt Harvey and Sonny Gray -- and that development undoubted coincides with his use of the splitter.

    The other reason he has been able to achieve weak contact on a consistent basis is location and movement on his fastball. Over the previous two years with the Twins, Pelfrey’s low-90s fastball was mostly seen hovering over the middle of the plate. Now he is hitting the low corners of the zone with solid movement:

    The results have been his highest ground ball rate on the pitch since 2010 because hitters are unable to barrel it up.

    While this may feel like an Arrested Development’s Ann moment, Mike Pelfrey has been good this season (“Him?”) and if he continues to twirl pitches the way he has while receiving competent infield defense behind him, he just might maintain throughout this surprising season. At the same time Pelfrey has outpaced his strand rate, benefited from the lowest batting average on balls in play of his career all while posting the second-lowest strikeout rate of his career -- there is room for regression.

    I'm starting to think that if Mike Pelfrey continues his run of success and the Twins are leading the division at the trade deadline, Mike Pelfrey cannot be traded.

     

    If the Twins truly are trying to "win now" the Twins cannot afford to get rid of the guy who is the staff ace this year.

     

    The Twins cannot continue to "build for the future" because the future could very well be this year. 

    The Twins are always afraid to part with their players who are at the peak of their career with the Twins. If I was given a nice offer, I'd send Pelfrey away. Regression is going to come eventually, not just for Pelfrey but for the Twins too.

    Yesterday he threw a split at 79 and followed it up with a fastball at 94.  That is a really large difference - like Johan in his heyday.  Last year, it seemed that everything was the same speed.

     

    I am starting to think this will not be a fluke.  As long as the Twins are in contention, you keep him.  What to do with hm next year if he keeps pitching like this will be a very interesting question.  Right now, I like him better than any other starter we have.

    Mike Pelfrey has elevated his "floor" value to the Twins immensely. Now, instead of being a dubious over-30 pitcher on his way down, he looks like an inning-eating mid-rotation guy that can win a surprising number of games if he's supported by good defense and a little hitting.

     

    His heater is better, thanks to good movement and better command. He's been keeping it generally down, but clearly he can move it around the zone and avoid the middle, without issuing walks. His slider is nothing amazing, but nobody sits on it, so he can throw it almost any time.

     

    The big news is that splitter. Used to be that hitters could sit on Pelfrey's fastball and expect to get something in the middle part of the zone sometime during an at-bat. Now his heat is around the zone, not down the middle, and if you sit on it, he'll throw that excellent splitter, which he delivers with almost the same arm action as his heater. With its late down-left action, it's extremely hard to judge where that ball is going to be when a hitter initiates his swing. Even if they do make contact, it's going to be a weak grounder or some weird little squibber. More likely a lefty fouls it off his foot, and a rightie just whiffs. Thing is, he throws it with two strikes, and it looks like a BP fastball down the middle, so they can't prevent themselves from swinging.

     

    The last factor is stamina. Dick and Bert both noticed how strong Pelfrey still looked right into the 8th inning. His heat was still 93mph or better, and his command had not degraded to the point where hitters could really take advantage. Granted, they were starting to zone in on his heat, but a couple good catches ended the game. Maybe Pelfrey needs a slightly different pitch pattern for the eighth inning.

    As long as the twins are within 4 games at the trade deadline, trading Pelfrey would be the worst possible move Ryan could make (unless you get a kings ransom in return) as it would send a terrible message to the fan base(we sucked for 4 years but hey let's suck for one more year! 20 game plans now on sale!)

     

    I would extend Pelfrey now if the price is right (2 years 16-20 million based on IP) worst case scenario he is a back end rotation guy or a great bullpen guy.

    Just as it used to be that I cringed when a ball was hit to Trevor Plouffe, I also cringed when Mike Pelfrey took the mound.

     

    Neither one of those things is true this year.

     

    I think this last start plus the two starts against Boston is probably a sign it is not a fluke.

    Extend and trade aren't the only two choices. They can also let it play out. If he finishes strong with better than league average ERA they can make him a qualifying offer.

     

    They can't trade him at the deadline if he continues strong and they are contending.

    Dave,

     

    Assuming Pelfrey is being considered pitching at his bets. you don't want to trade a veteran at his high peak value while you can?

    Not when the twins are sporting the best record in the entire AL!

     

    At some point you have to play for today, and that time is now.

     

    I'm sure the Twins could have gotten a couple nice prospects for Jack Morris at the deadline in 1991, but I'm happy with how it all turned out.

    But that's not what you said, buddy.  You said, 'As long as the twins are within 4 games at the trade deadline'.  

     

    I remember Ryan trading Castillo back when we were, what 6-7 games back of a playoff spot? One of his reasons he said he did that was that he'd rather get something for him than not since he wasn't going to re-sign him,  That went over like a ton of bricks with the fans and the players.  So yes, like you said, that would send a horrible message.

     

    it could happen though.

    If they are in the playoffs, they better not trade him unless they already got a better pitcher added somehow........so no, I can't believe they'd repeat the mistake of dealing while they are in the race, and getting worse......I just can't believe they'd do that again.

     

    And yes, I think there is a decent shot they sign him again.....and Hunter......

    Clearly yesterday Pelfrey's splitter was devastating but most MLB pitchers go through stretches of dominance at some point during the season.  One game does not a season make.  If the Twins are seriously thinking of resigning Pelf at this point I would be pretty disappointed.  There's a month and a half left before the deadline.  Let's wait and see how things go in his next 8 starts.  If he's striking out a batter per inning at that point then maybe you start a conversation with his agent.
