D-Train Returns to Majors

At the All-Star break, the Cincinnati Reds have a record of 45-47 and look up at the Pirates, Brewers and the Cardinals in the National League Central standings. The defending division champs sit in fourth place due mostly to a disappointing starting rotation. Cincy's rotation was supposed to be a source of strength, boasting  great depth if not ace-caliber talent. Instead, injuries and uncerachievement leave Reds starters with the second-worst fielding-independent ERA in the major leagues.

Showing just how thin the club's staff has been stretched, the Reds turned to Dontrelle Willis on Sunday to start in place of Edinson Volquez, who was optioned to Triple-A to rectify his control issues. Willis, the 2003 NL Rookie of the Year who averaged better than three Wins Above Replacement with the Marlins in his early-to-mid-twenties, has since contracted a serious case of Steve Blass Disease.

The left-hander scarcely pitched at all upon being traded to the Tigers along with Miguel Cabrera, missing time in 2008 with knee and forearm injuries and then seeking treatment for anxiety disorder in 2009. Last year, he was acquired by the Diamondbacks for a song during the summer and was released a month later, latching on with the Giants to finish the season. His strikeout-to-walk ratio in the majors from '08 to '10 was 82-to-119 in 123.1 innings pitched.

Prior to his call-up, the now-29-year-old D-Train showed some signs of getting back on track. He posted a 67-to-20 K/BB ratio at Triple-A Louisville, with a 3.12 fielding-independent ERA and a ground ball rate above 50 percent in 75.1 innings. Making his first MLB start in over a year on Sunday against the Brewers, Willis allowed two runs in six innings pitched, surrendering six hits while walking and whiffing four hitters each.

Here's a look at his pitch break and velocity from Sunday:

Willis relied on a fastball/slider mix, with a few changeups and seemingly a cutter thrown in as well. His fastball sat at 89 and topped out at 92, his slider averaged around 81 and his cutter came in a few ticks higher than the breaking ball. The changeup averaged 84 MPH.

He got ahead of hitters at a surprising clip, getting a first pitch strike to 19 of the 26 batters that he faced while throwing almost exclusively fastballs in those situtations. So, why did he still issue four walks? Willis got strikes with his fastball about 64 percent of the time and his cutter 66 percent, locating those pitches within the zone often:

The D-Train's first start with the Reds was a mixed bag. He threw his fastball and what looked like a cutter for strikes while recording 10 ground ball outs, but his slider was sloppy and hitters accordingly laid off the pitch. It's hard to envision long-term success for Willis, but the fact that he's even on a major league mound constitutes major progress at this point.

Johnny Cueto's Unusual Changeup

Johnny Cueto of the Cincinnati Reds throws a very unusual change up.  The uniqueness of the pitch stems from the spin he imparts to the ball.  The following graph shows the relationship between the spin on his fastball and the spin on his change:

The type of movement seen in this change up suggests a slider, but Johnny throws a very good one of those:

Cueto throws his change the least, and it is also his least productive pitch.  He records weighted On Base Averages (wOBA) of .167 on his slider, .275 on his fastball and .291 on his change.  Those are all very good, but it's clear he gets much better results on his slider, which is why he throws it 2.5 times more than his change.

Given the spin of the pitch and batters ability to hit it, I wonder if his change ups are really poorly thrown sliders.  A slider that didn't move much would explain why batters get more offense out of the pitch.

Aroldis Chapman, the Cuban Missile in Crisis

Do you get the feeling that Aroldis Chapman of the Reds is uncomfortably familiar these days with the old song, “Wild World,” by Cat Stevens?

As I look at Chapman’s stats, Stevens’ lyrics keep resonating in my head,

“Oh, baby, baby it's a wild world
It's hard to get by just upon a smile.”

In Chapman’s case it's hard to get by just upon a 105 mph fastball if you can’t control it.

Over the last month, Chapman is everywhere but home plate. This season, the Cuban Missile, as the lefty is called, has 20 walks, 15 strikeouts and a 6.92 earned-run average over 13 innings. He has walked 12 batters and managed only four outs in his past four appearances, twice leaving before retiring a batter. On Sunday, Chapman walked four of five batters his faced in the 9th inning, leading to a five-run Cardinals comeback. He managed only five strikes in 18 pitches. As a result the Reds put him on the DL, more the Dysfunctional List than anything else.

Take a look at Chapman’s fastball over the last month (April 17 – May 17):

In some respects his slider is even worse, because when it is not in the strike zone it is right down batters’ power alleys.

It is indeed a wild world these days for Chapman and the Reds need to find out why, which is primarily why he is on DL at this time.
