I've been trying to go to every baseball stadium and I'm suppsed to go to 2 new ones this year:

1st base=willie stargell (pirates vs padres in san diego)
2nd base=roberto alomar - toronto skydome
shortstop = derek jeter - yankee stadium
3rd base = chipper jones - fulton county, turner field
rf=shawn green - toronto skydome, tropicana field (blue jays visiting)
cf=ken griffey jr - camden yards, fenway park
lf=barry bonds (yuck) - sbc ballpark san fran
catcher=mike piazza - dolphins stadium (pro player), veterans stadium, wrigley field, all star game 97 in cleveland
i've seen lots of pitchers but i'll go with josh beckett, tom glavine, curt schilling (ugh), and greg maddux - i've seen them all between turner field, fulton county and dolphins stadium.

1B: Frank Thomas (Comiskey)
3B: Robin Ventura (Comiskey)

I've also been to many Brewers games over the years, but for the life of me I can't remember if any players stood out to me. I've looked up names, but nothing rings a bell.

Ryan Giggs - winger

Ah, this is crazy. I've seen so many. I'm gonna include a lot of favorites, rather than just best players, because it'd be too hard to pick the absolute best at each position.

P: Randy Johnson (Bank One Ballpark)
P: Orel Hershiser (Dodger Stadium, BOB)
P: Curt Schilling (BOB, Dodger Stadium)
P: Kevin Gross (Dodger Stadium - okay, he's not one of the best or a favorite, but I saw him no-hit the Giants, which was badass)
C: Mike Piazza (BOB - never saw him in his prime, though)
1B: Eric Karros (Dodger Stadium - sentimental favorite)
2B: Ryne Sandberg (does spring training count? HoHoKam Park)
3B: Matt Williams (Phoenix Municipal Stadium when he was in the minors, Dodger Stadium, BOB)
SS: Barry Larkin (Dodger Stadium, BOB)
OF: Barry Bonds (BOB - not a favorite, but he's damn good)
OF: Steve Finley (BOB - amazing center fielder)
OF: Luis Gonzales (BOB)

I honestly can't remember... I've seen Griffey play a few times, still have an Ozzie Smith autograph on a Phillies ticket stub... I've seen Curt Schilling pitch...

Darren Daulton baby... I have an autographed rookie card of his and I think it's worth like 50 cents

excellent. nice nod to EK

btw, the No No was cool, but Kevin Gross is on my list of all time most hated dodgers. Him and Jim Gott, to name 2

Maddux, Glavine, Smoltz.

im just listing the notables that ive seen.

SG - Michael Jordan
PG - Allen Iverson, John Stockton, Steve Nash
PF - Charles Barkley, Dennis Rodman , Karl Malone, Chris Webber
SF - Scottie Pippen, Dirk Nowitzki, Lebron James
C - uh...Manute Bol

C Pudge
1B Palmeiro/Teixera
2B Soriano
SS Guillen/Tejada/Jeter
3B Mora/Blalock/ Ventura
LF Shannon Stewart
CF Torii Hunter
RF Maggs (openming day this year)
DH Mauer/D. Young

P. Bonderman/Santana/Sabathia/Percival

if you cant tell...the yankees game was like 7 years ago, so i dont remember everyone....and i went to an O's,Rangers, Twins, Indians, Royals games last year

only started going to a lot of games these last couple years...these are all at Tiger Stadium and Comerica....i cant remember anythign from when i was younger

catcher-mike piazza-dodger stadium
1st base- mark mcgwire- dodger stadium
ss-derek jeter- angels stadium
of- barry bonds- dodger stadium
of-ken griffey jr-dodger stadium
of-ichiro-dodger stadium
p-hideki irabu-angel stadium

personally, i dont think i'll ever see a better starting pitcher than pedro from 98-00 with the sox. his 3 year avg during that span: 221.1 IP, whip of .992, era of 2.25, 283 K's. his 3 year record was 60-17. in 2000 he gave up 42 earned runs in 29 starts.

i still think he was robbed of the mvp in '99. his performance in game 5 of the ALDS, coming out of the pen against cleveland, for the last 6 innings was the best pitching performace that i've ever seen.

C - Mike Piazza (Wrigley)
1B - Mark McGwire (Wrigley)
2B - Ryne Sandberg (Wrgiley)
3B - Chris Sabo (Greatest 3B of all-time, Wrigley)
SS - Derek Jeter (I hate to say that he is the best i have seen, but really none other come to mind , Wrigley)
OF - Sammy Sosa (Wrigley)
OF - Larry Walker (Coors)
OF - Manny Ramirez (The Cell)
P - Pedro Martinez (The Cell)

Pete Rose Jr. - Victory Field (Indianapolis)

I once was on the field for a free clinic and I caught a pop-up from Eric Owens at a AAA game and got to say hey to him.
