i like brad james alot. his control isn't the best, he doesn't K very many batters, and he isn't very young, but he gets a shitload of groundballs, and he prevents solid contact better than any pitcher in the astro system.

gutierrez and paulino combine to provide the kind of high upside arms that are present in any legitimate system. they are a little old, though, and the organization doesn't appear to have any plan for restocking the system with these types of arms once gutierrez and paulino graduate, but these two should start to pay dividends to the astros this season.

bud norris didn't take the workload that a college pitcher usually takes in his first full professional season, which is a plus, from my point of view. he pitched very lightly his first 3 months, but when he hit his stride in july, he was dominating, albeit as a 22 year old in low A. he backed this up with an impressive performance in the hawaii winter league, but again, he wasn't facing the highest level of competition. i see a lot of good markers in his performance though, from his K rate, to the spike in his GB rate in HWL, to the favorable splits versus LHB, which indicates a quality changeup.


Spotlight: Matt Albers

albers throws a hard 2 seam fastball that sits in the low 90s and generates a good percentage of groundballs. albers also throws a curve that sits around 79 MPH, and a changeup that sits in the low 80s. his pitches work well together, and his curveball is especially effective.

i've seen reports that have albers fastball as hitting 97 MPH, but i don't think it needs to hit that high note to be effective, nor do i think he'll be able to fall back on that whenever he gets in trouble. as it was in 2007, his fastball had plenty of movement which generated plenty of swinging strikes, and looks to have the potential to keep albers in the middle of a good rotation for the next 6 years.

when pitching in houston, albers had a 4.35 ERA with a 2:1 K:BB ratio and mediocre HR and H rates. when pitching on the road, albers' ERA ballooned to 7, he had more BBs than Ks, his HR rate jumped to more than twice league average, and he allowed 1.66 baserunners per inning.

having previously looked at the uniqueness of 2 astro starters, i'm close to throwing my hands up in the air and proclaiming that there's just something in the water, but as i'm not there yet, i'll just say that this is one more thing i need to keep my eye on.

Anatomy of ERA

take a look at these two lines for two houston astros SPs:

Pitcher A: 54.7 IP 54 H 14 BB 50 K 6 HR 3.50 DIPS
Pitcher B: 55.0 IP 58 H 16 BB 27 K 5 HR 4.34 DIPS


the difference in ERA for these 2 starters is a full run. for those of us who subscribe to voros mccracken's DIPS theorey, it would be expected that pitcher A has the lower ERA. that is not the case, though. pitcher A, wandy rodriguez, has an ERA of 4.45 while pitcher B, chris sampson, has an era of 3.44.

the main difference between these two pitchers' statistics is that wandy rodriguez has struck out 23 more batters than sampson. everything else is remarkably similar. according to DIPS, rodriguez's 23 extra strikeouts give him an advantage of 8 tenths of a run in expected ERA. what factor could possibly be significant enough to account for the 1.8 run difference between expected DIPS era and actual ERA?

the answer is not as sexy as one might think. it all comes down to the difference between pitching with the bases empty versus pitching with runners on. here are the numbers:

Chris Sampson:
bases empty: 133 PA .296/.338/.488 12 XBH 5 HR
men on: 99 PA .247/.320/.329 6 XBH 0 HR

Wandy Rodriguez
bases empty: 133 PA .262/.301/.421 12 XBH 3 HR
men on: 94 PA .256/.326/.476 11 XBH 3 HR

it really is that simple. 5 more XBH and 3 more HR with men on base led to 8 more runs scored on rodriguez than were scored on sampson in this situation.

i think this is a trend that warrants tracking through the rest of the season. i've seen it exhibited by relief pitchers such as geoff geary, and have had this to say in the past about it:
"to guess why there is such a profound difference between geary's performance with runners on base and with the bases empty, i would say that with the bases empty, geary elevates his fastball earlier in the count, leading to more solid contact against. without looking at video to confirm, i can only guess that geary's front side flies open in the windup, leading to the higher pitch location."

i have yet to follow up on geary's situation, but i will keep an eye on both he and sampson to see what similarities they posess.
