It?s sometimes impossible to tell in baseball which players are going to breakout and which are going to fall off the face of the planet. Every season, different players do both of these things, and much of the time it?s unexpected. Other times, however, Miss Cleo is unnecessary to predict these occurrences. To demonstrate this feat, here are my top three breakout stars and declining overachievers. Players Most Likely to Have a Breakout Season 1. Brad Wilkerson, OF, Texas Rangers Wilkerson had a disappointing 2005 that was filled with not only injuries, but lacklustre performance when he was healthy enough to play. After a huge step forward in 2004, 2005 was an equally huge step back. 2006 should prove to be a different story; in being traded to Texas, not only will he now will enjoy the luxury of playing in the ultimate launching pad stadium of the AL. but he will also be protected in the lineup by such premier hitters as Mark Teixiera and Hank Blalock . He?s always drawn bushels of walks, so if he can stave off the injury bug and regain his power stroke, this could be a monstrous campaign. 2. Joe Mauer, C, Minnesota Twins Mauer?s rookie year was cut short by injury, so 2005 was his first full season. His sweet stroke allowed him to bat for high average while keeping his strikeouts down, which is not an easy feat for such a young player. The one thing that was missing, though, was the power he flashed in 2004. Look for him to put it all together in his third year and establish himself as one of the premier catchers in the game. 3. Chris Young, SP, San Diego Padres We already discussed the effect of a hitter moving into Texas; here is the exact opposite. Young put up very respectable numbers in Texas last season while playing in a stadium known for terrorizing pitchers. He?ll be suiting up in San Diego this year, though, which means he?ll now be pitching in arguably the best pitcher?s environment in the league today. He?s still quite young, but last year seemed to start picking up the finer points of pitching. If he can put it all together this season, watch out. Players Most Likely to Decline 1. Kevin Millwood, SP, Texas Rangers You may be seeing a trend at this point: the stadium in which a player plays has a large effect on his numbers. No one should experience this season more than Millwood, who put up a fluky low ERA last season in Cleveland, and is now moving to Texas, where they?ll soon be regretting their massive investment. It?s a train wreck waiting to happen. 2. Gary Sheffield, OF, New York Yankees Sheffield put up very solid numbers last year; that is not what I?m disputing. The problem arises, though, when you look at his career stats, and realize that he?s been in a marked decline for the past two seasons now. His power has been slowly diminishing, and he?s now entering his late-30s. All of these point to a possible collapse in the making; if nothing else, he?ll fall out of the ranks of stardom and become a merely very good player. It could be worse; it?s not like he?s been traded to the Royals or something. 3. Garret Anderson, OF, Los Angeles Angels of Anaheim He put up a superficially good season in 2005 with some gaudy RBI totals, but don?t be fooled: he?s way past is prime, and this year I predict age and injuries will finally catch up with him. He?s turned from a fabulous hitter into an overrated ?run-producer?. A collapse is inevitable.
