If I was a GM or a real baseball team, I'd take #1.
Simple reason: Just take a look at guys who have produced those numbers and ask yourself. Which NAME would you take?
Summary of Analysis:
Player #1 - Tony Gwynn, Ichiro Suzuki, Pete Rose, Wade Boggs. Only Gwynn hit above .380 in 1994. So even getting to .385 is an enormous feat. Obviously, you are emphasizing the low power numbers which is why I chose those four guys.
All four of them are HALL OF FAMERS!
Player #2 - Ryan Howard, Mark Reynolds, Jack Cust. Actually those numbers are Jose Bautista's exact stats in 2010. None of them are Hall of Famers. All of them have faded out. Howard couldn't hit breaking balls. Bautista has injury issues. Jack Cust and Mark Reynolds are inconsistent players who regress every year.
53 HRs and 125 RBIs are appealing but that .260 tells you a different story. There's only about 5-7 guys that can bat that high in the last 25 years. All of them hold multiple batting titles and had illustrious careers in the MLB. Meanwhile, it was easy to find low average power guys every single year. They are very common and not worth a long-term contract as history and statistical analysis has proven.
Analysis: Nobody has hit that high since Tony Gwynn in 1994 (.394). Todd Helton (2000), Nomar Garciaparra (2000) and Ichiro Suzuki (2004) all reached .372 in the early 2000s. They've all had very high batting averages throughout their careers so it's already a good sign that player #1 can hit that high. There have been several players that have had .360s in the past few years like Mauer. Someone batting .385 with 88 RBIs means that this guy is a hitting machine and probably leading off. We are talking about a player who can get MORE hits than Ichiro or Pete Rose in their prime. That's just crazy. Guaranteed top-10 MVP vote getter every year with those numbers. So I'm taking him for sure!
Do the math. 600 AB. .385 average gives you 231 hits. In a 162 game season, that's 1.42 hits per game. We don't know his walk/OBP numbers but we are talking about an insane On-Base Percentage.
Let's say he gets 50 walks, 5 HBP, 5 SF (reasonable numbers for high average guys). Add the numbers. OBP = .433
Here's how his OBP would rank the past few years.
2012 - #1
2011 - #3
2010 - #1
2009 - #3
A guy getting on-base 43% of the time he's up there? Not to mention, he is going to at least get a hit or walk every game? (Realistically, he won't hit every game which means that he'll have tons of multi-hit games.)
Player #2 is swinging for the fences most of the time. He probably has a lot of strikeouts with tons of walks.
.260-50-125 reminds me of players like Mark Reynolds and Ryan Howard. In 2009, Reynolds hit .260-44-102. He led the league in strikeouts. From 2007-2009, Ryan Howard averaged 47 HR with .266 and 141 RBIs. Both players regressed as they approached age 30. Also note, both guys couldn't hit breaking balls so teams figured them out very quickly.
In 2010, Jose Bautista hit .260-54-124. He had another good season in 2011 but has sustained injuries since then. It's a pattern with these low average big power guys. Injuries eventually get to them and their level of play significantly drops as they hit age 30. Once their bat speed or flaw gets exposed, it's game over.
For fantasy baseball, of course you take #2. 50 HR players now a days are very rare. Fantasy baseball rewards power hitters especially if you have a player who is top 5 in both HR and RBI. (Think Jose Bautista) It will also mean that he is in the top 10 or 20 in runs scored. That's three categories that he contributes towards. Meanwhile, player #1 will only contribute to one or two categories. (Assuming we are playing a standard 5 x 5 format.)
