I had been hoping to write about Bowker's 2007 season at some point and show how good a season he had and thus is a good prospect to watch out for, but obviously that ship has sailed, so instead I'll explore a corollary question: is this real or not?
Feels Like the First Time
For Giants fans who were living under a rock this weekend, Bowker was called up this weekend, started Saturday and Sunday and only hit two home runs, going 4 for 6, and driving in seven runs. He got the call-up late Friday night and got around 3 hours sleep taking Fresno to S.F. route to the majors. Luckily, it was a home game on the weekend, so he was able to get tickets for his parents and I presume friends and family as well. Major league life can't get any better this this. What a dream start to a major league career!
His homer in his first game put him in a select group of eight San Francisco Giants who had homered in their first game, including Giants greats Willie McCovey, Orlando Cepeda, Bobby Bonds, Will Clark, Matt Williams, and John "the Count" Montefusco. With his homer yesterday, he is all alone, the only player in the Giants 50 year history in San Francisco to homer in his first two games.
Just all in two day's work. Today, he gets a well-deserved rest, no use testing the Baseball Gods and batting him against Randy Johnson, one of the nastiest lefties in baseball history, even if he is in his mid-40's now. Some may quibble, but why do that to him?
2007 Breakout Season
Despite playing in that hellhole of a park in Norwich, he was still 12th overall in OPS, 7th overall in SLG. And he was a 23 year old playing in a league where the average pitcher was 25 years old, which means that despite the two extra years of experience that the pitchers he faced had, on average, he still knocked them all around the park:
2007: .309/.364/.529/.893, 22 HR in 518 AB, 24 AB/HR
Home: .271/.330/.422/.752, 6 HR in 251 AB, 42 AB/HR
Road: .345/.397/.629/1.027, 16 HR in 267 AB, 17 AB/HR
As I have shown in previous analysis of the Dodd Stadium homefield "advantage", the park, for whatever reasons, damps down power, both doubles and HR power, relative to the parks in the rest of the Eastern League, costing our prospects some 30-50% of their slugging percentage had they played all their games on the road. Bowker, despite some heavy hitting, was not unaffected by this.
In addition, Bowker improved as the season went on, showing that he figured out the pitchers more than they figured him out:
APR: .306/.342/.500/.842, 3 HR in 72 AB, 24 AB/HR
MAY: .263/.303/.500/.803, 4 HR in 118 AB, 30 AB/HR
JUN: .345/.398/.584/.983, 5 HR in 113 AB, 23 AB/HR
JUL: .284/.364/.526/.891, 5 HR in 95 AB, 19 AB/HR
AUG: .330/.391/.509/.900, 5 HR in 112 AB, 23 AB/HR
Comparable MLEs
MLEs is a well established method of translating minor league stats into Major League Equivalent statistics (from, natch, Bill James), but, of course, like all in life, most have taken from the master and made their own proprietary try at this. Most try to translate based on level, age of player, and other variables. As I've noted, there is really no knowledge to be gained from utilizing his home stats because of the severe skewing of his stats there, and thus his road stats are a better proxy for how he would have performed in AA (and thus MLE).
The closest players in age and performance to Bowker are Nolan Reimold and Steven Pearce. Reimold is the same age (Pearce is a year older) but Pearce had the higher OPS. Neither had an OPS as good as Bowker's road numbers (1.027 vs. 0.986 for Pearce and 0.930 for Reimold), but they are close enough:
Bowker: .345/.397/.629/1.027, 16 HR in 267 AB, 17 AB/HR
Pearce: .334/.400/.586/.986, 14 HR in 290 AB, 21 AB/HR
Reimold: .306/.360/.565/.930, 11 HR in 186 AB, 17 AB/HR
From Ron Shandler's Baseball Forecaster:
Pearce: .293/.341/.496/.837, 15 HR in 412 AB, 28 AB/HR
Reimold: .271/.324/.501/.825, 10 HR in 186 AB, 19 AB/HR
Thus according to the MLE's of Ron Shandler's methodology, two hitters who were not as good as Bowker, are expected to hit around .830 OPS with around 20-25 AB/HR power (or about 20-25 HR in a 500 AB season). Both were singled out by Shandler's method as part of a pool of the best rising prospects.
Here are their road numbers:
Bowker: .345/.397/.629/1.027, 16 HR in 267 AB, 17 AB/HR
Pearce: .333/.403/.587/.989, 6 HR in 138 AB, 23 AB/HR
Reimold: .330/.375/.546/.921, 5 HR in 97 AB, 19 AB/HR
Again, very comparable, and Bowker is on top.
Real or Not?
Given that he hit as well as two highly ranked prospects as Pearce and Reimold in AA, I think that Bowker is, if not the equal in prospect-goodness as these two, he is very close. Of course, the fear is that 2007 is the fluke and the prior suckiness he had was the real Bowker. But he is now 24 years old, 25 later this season (last season counted as his year 23 season), so he is at the right age when physical maturity and experience can start kicking in and he start hitting better.
And it was not like he was a lowly considered prospect. When he was drafted, he was considered a future power hitter. In their 2006 prospect book, Baseball America noted, "He [Bowker] has more raw power than most other San Francisco farmhands... He has premium lefthanded power, and the key to bringing it out is maintaining his aggressive approach. He had an injury-plagued career at Long Beach State, redshirting as a freshman because of problems with his right wrist, and still is gaining a feel for his all-out swing... Bowker's bat is his ticket. He's a below-average runner with decent outfield skills and a fringy arm. They played him at first base in instructional league..." He was ranked 21st that year.
In their 2008 book, they wrote: "Bowker held his own over his first three minor league seasons, but hadn't flashed the power San Francisco expected when it drafted him in the third round. The power arrived at an unlikely place last season, as Bowker finished third in the pitching-dominated Eastern League with a .523 slugging percentage. Bowker arrived in spring training last year with added muscle and began to flourish when coaches suggested he stand closer to the plate. He combines the ability to hit for average - he's a career .296 hitter - with pull power. He has strong hands and can hit good fastballs. The Giants loves his aggressive approach and work ethic. He's limited to left field because he has below-average speed and his range and arm are adequate at best..." He was ranked 9th this year.
On the other hand, the 2008 Minor League Baseball Analyst book by Deric McKamey, rates Bowker as above average for power, average for batting average, and projects him as a platoon LF/RF, stating "Tweener outfielder with quick hands and extension that allows him to stay on baseball and hit for BA. Produces moderate power to pull field, and could help fortune with improved plate discipline. Ranges well in outfield, but possessess slightly below average arm strength."
However, they are not accounting for the Dodd Stadium effect. Both Pearce and Reimold rates a premium power hitters. And I think why he was evaluated only as a platoon outfielder is because his MLE based on his Dodd-depressed numbers places him as a mid-700 OPS hitter. If you look at his splits, he clearly does hit RHP much, much better for power:
v.LHP: .331/.390/.460/.850, 2 HR in 139 AB, 70 AB/HR
v.RHP: .301/.355/.554/.909, 20 HR in 379 AB, 19 AB/HR
And given a projected mid-700 OPS, that smells like a platoon OF. But if he can hit in the low 800 OPS overall, that is a major league average OPS for a corner OF, and makes him starter material.
The key question this season is whether the Bowker of 2007 or the Bowker of Before is the real Bowker. Obviously, with the hitting display of this weekend, that small samples will drive Giants fans giddy with anticipation. I think, given the comments by Baseball America, the depressive effects of Dodd Stadium - else his breakout season would have really opened some eyes, leading the Eastern League in OPS, rather than simply being in the top 10 - and how players who are similar to him in hitting on the road were rated much higher than he was, the 2007 Bowker was the real Bowker, and hopefully he will get a chance to show what he can do in the majors this season.
I think that Sabean needs to work harder at trying to move Randy Winn so that Bowker, Lewis, and Schierholtz get more ABs to start this season. It was risky to have done that in the pre-season as many Giants fans had clamored for, but I think all three prospects have shown enough that they deserve to get the shot to show what they can do in the Giants outfield, the time is right, now we need to find the right team to trade Winn to and get some good prospects for him.
