Twins Video
With how poorly Gibson has pitched, it's surprising he's held on to his rotation spot this long. Gibson had a marvelous first half of 2015, but since then he's pitched to a 5.39 ERA over 250.2 innings. Opposing batters have an OPS over .800 against him and his WHIP is 1.53 in that time frame.
Gibson's career ERA+ is at 86, which is exactly the same as Nick Blackburn's career mark. Meanwhile, Berrios was named Twins Daily's Minor League Pitcher of the month for April after posting a 1.09 ERA and 0.79 WHIP for Rochester. Adalberto Mejia, who made three rough starts with the Twins, looked great in his lone start for the Red Wings (he's scheduled to pitch again Thursday).
Nick Tepesch will slot in as the fifth starter Saturday. The 28-year-old had a 2.00 ERA and 1.33 WHIP over three starts for Rochester. If Tepesch can establish himself as a reliable starter, that may cause Gibson more trouble than anything. When they feel the time is right Berrios is coming up, it's just a matter of who gets booted from the rotation.
Last Sunday on Go 96.3's excellent weekly programs Inside Twins and The Paul Molitor Show, both Derek Falvey and Molitor mentioned first-pitch strikes when asked about Gibson. Here's what Falvey told Cory Provus:
"Sometimes he's trying to get a hitter to swing at something out of the zone early and what ends up happening is major league hitters make adjustments, just as pitchers do, and he has a tendency to be too fine."
Among pitchers with at least 20 innings this season, Gibson has the third-worst first-pitch strike percentage at 50.5. He was at 59.4 last season. During that excellent first half of 2015, he was all the way up to 63.
It's pretty much universal that pitchers do much better when ahead in the count, but is that especially more important to Gibson than any other pitcher? Here's a look at how his career numbers compare to the other veteran starters on the Twins. For additional reference I also included Corey Kluber, Justin Verlander and Jose Quintana's numbers.
Batter Ahead Minus Pitcher Ahead OPS
Hughes: .332 (.943 OPS-.611 OPS)
Quintana: .352 (.896-.544)
Gibson: .358 (.919-.561)
Santiago: .373 (.931-.558)
Santana: .407 (.956-.549)
Verlander: .461 (.918-.457)
Kluber: .484 (.946-.462)
So being ahead hasn't been especially key to Gibson compared to these other pitchers. In fact, among the Twins' starters Gibson has the lowest OPS against when he's behind. But how about that first pitch in particular?
After 1-0 Count Minus After 0-1 Count OPS
Quintana: .116 (.762 OPS-.646 OPS)
Hughes: .121 (.804-.683)
Santiago: .150 (.788-.638)
Gibson: .171 (.814-.643)
Verlander: .191 (.743-.552)
Santana: .192 (.815-.623)
Kluber: .228 (.757-.529)
So, getting the first-pitch strike doesn't exactly make a huge swing for Gibson in comparison to these other pitchers, either. But again, it's always better to get that first strike, no matter who you are.
Career First Pitch Strike Percentage
Hughes 67.3
Quintana 65.7
Kluber 62.4
Santana 62.2
Verlander 61.5
Gibson 58.1
Santiago 56.5
I'm going to start calling my boy Hector Santiago "The Exception" because he's the outlier in so many situations. Terrible first-pitch strike percentage, yet still has a career ERA+ of 105, go figure. Gibson, like most other muggles (I suspect Hector may be a wizard), has not been able to overcome that poor first-strike rate.
So what's the point of all this madness? Well, before I pulled all these numbers I was wishfully hoping I'd find Gibson was a pitcher who was better than average when ahead in the count. That way, I could at least buy into the idea that with more first-pitch strikes he could return to being a solid piece to the rotation. That does not appear to be the case.
There's also the issue that Gibson has been dreadful the second time through a lineup over his career. One more goofy made-up stat ...
Second PA Minus First PA OPS
Gibson 107 (.827 OPS-.720 OPS)
Santana 58 (.742-.684)
Kluber 39 (.706-.667)
Hughes 15 (.755-.740)
Verlander -1 (.637-.638)
Quintana -30 (.665-.695)
Santiago -66 (.668-.734)
Brad Radke -73 (.704-.777, had to toss him in just for fun)
Most starters really struggle the third time through a lineup, but Gibson doesn't make it that far. He gets clobbered the second time around. If that doesn't scream "reliever!" I don't know what does.
So, even if he does a better job at starting out with strikes, Gibson's upside is probably mediocre at best. But let's assume for a moment he does bounce back to respectability, then what?
Gibson's only making $2.9 million this season, but that'll increase through arbitration. While that's very affordable for a starting pitcher, his competitors make the league minimum and will continue to do so next season.
How many more starts would you give Gibson? And if he's removed from the rotation, would you rather see him in the Twins' bullpen or the Rochester rotation?
