Early fantasy surprises

Vernon Wells (.324, 7 HR, 13 RBI)
He looks healthy, and has been mashing everything in sight. Is he back to being the .303/32/106 guy of 2006? His batting average has fluctuated wildly in his career but we can safely bank on his career average of .281, with 25+ HR and close to 100 RBI. Verdict: believe.

Jose Guillen (.352, 6 HR, 15 RBI)
The early favorite for comeback player of the year, since he narrowly avoided death during the offseason due to blood clots. He played full seasons in 2007 and 2008, and averaged around .280/21/95 RBI. There's no reason to think he can't equal or surpass those numbers this year, but a .300/30/100 season is highly unlikely. Verdict: Sell high.

Chase Headley (.379, 14 R, 5 SB)
Up and coming young player, whose minor league numbers (.301/.399/.500) suggest a solid major league hitter. He has already stolen more bases this season than in any of his minor league seasons. Expect fewer steals and more home runs, although 20 HR might be his ceiling this year. He's only going to get better. Verdict: believe.

Kelly Johnson (.327, 6 HR, 13 R)
Unceremoniously dropped by the Braves, KJ has found a new home atop the Dbacks order and has been cranking home runs at a prodigious rate. He is 28, so this could be a step forward, but let's remember that his career high in the majors is 16 HR and a .287 average. As a 2B, those are nice numbers, but someone in your league might believe he can hit .300 with 25 HR and 100 runs scored. Verdict: Sell high.

Scott Podsednik (.397, 7 SB)
The Scott Pod did hit .304 in 132 games in 2009, but he's 34 years old and a career .279 hitter. He hasn't played more than 139 games in a season since 2004. Pencil him in for 30 steals, but expecting him to be anything more than a steals specialist on your team is asking for trouble. Verdict: Sell high.
