GCL Astros - German Perez & Raul Rivera

Cleaning up a little bit of the part-time starters/part-time relievers from the GCL Astros before we get into the full-time relievers, we'll hit up German Perez and Raul Rivera...

German Perez
How did he get here?: Signed contract prior to 2006 season
Stats: 5'11", 147 lbs, Throws: Lefty
Age as of April 1, 2010: 20

Cumulative line: 0-3, 14.1IP, 6.91 ERA/1.88 WHIP, 9K:9BB, .333 BAA, 0HR


as Starter (12.1IP), 8.03 ERA/2.03 WHIP, 4K:9BB, .356 BAA
as Reliever (2IP), 0.00 ERA/1.00 WHIP, 5K:0BB, .222 BAA

vs. LHB (3.1IP): 5.40 ERA/1.20 WHIP, 3K:2BB, .167 BAA
vs. RHB (11IP): 7.36 ERA/2.09 WHIP, 6K:7BB, .381 BAA

Home (6.1IP): 9.95 ERA/2.05 WHIP, 2K:5BB, .348 BAA
Away (8IP): 4.50 ERA/1.75 WHIP, 7K:4BB, .323 BAA

Bases Empty (9IP): 2.22 WHIP, 7K:10BB, .256 BAA
Runners on (12.2IP): 1.58 WHIP, 6K:3BB, .362 BAA
w/RISP (6.1IP): 2.05 WHIP, 3K:2BB, .407 BAA

August (6 games, 4 starts, 14.1IP): 6.91 ERA/1.88 WHIP, 9K:9BB

K/9 Rate: 5.7
BB/9 Rate: 5.7
Groundout/Flyout Rate: 1.38
K:BB Ratio: 1.00

Why look at a pitcher who only threw in six games in August for the GCL team? Because 2009 was Perez' 4th season in the Astros' organization, having spent 2006-2008 in the Astros' Venezuelan Summer League. Perez signed as a 16-year old, so he's still a younger guy. But 2007 was his most promising year, going 7-1 in 13 starts with 54K in 69.2IP, 2.07 ERA/1.11 WHIP. Since then, he's pitched in 15 games (7 starts) and totalled 40IP. Walks are up, Ks are down, but this was Perez' first season in the States.

Raul Rivera
How did he get here?: Drafted 37th round, 2009 draft
Stats: 6'3", 185 lbs, Throws: Right
Age as of April 1, 2010: 19

Cumulative line: 0-2, 15IP, 6.60 ERA/1.33 WHIP, 9K:3BB, .298 BAA, 2HR


as Starter (10.2IP), 4.22 ERA/1.06 WHIP, 6K:2BB, .237 BAA
as Reliever (4.1IP), 12.46 ERA/2.08 WHIP, 3K:1BB, .421 BAA

vs. LHB (5.1IP): 6.75 ERA/1.50 WHIP, 3K:3BB, .263 BAA, 1HR
vs. RHB (9.2IP): 6.52 ERA/1.24 WHIP, 6K:0BB, .316 BAA, 1HR

Home (10.2IP): 8.44 ERA/1.41 WHIP, 6K:2BB, .317 BAA
Away (4.1IP): 2.08 ERA/1.15 WHIP, 3K:1BB, .250 BAA

Bases Empty (9.2IP): 1.24 WHIP, 7K:2BB, .298 BAA
Runners on (5.1IP): 1.50 WHIP, 2K:1BB, .368 BAA
w/RISP (3.1IP): 1.50 WHIP, 2K:1BB, .364 BAA

August (4 games): 6.60 ERA/1.33 WHIP, 9K:3BB

K/9 Rate: 5.4
BB/9 Rate: 1.8
Groundout/Flyout Rate: 4.83
K:BB Ratio: 3.00

Rivera signed late, and only pitched in four games in August. That he spent one game as a reliever is a little misleading, as he threw 4.1IP in that one game.
