Between left field and first base, it’s likely we’re going to see a whole lot of John Mayberry early in 2012. And with good reason. Mayberry has shown enormous power with the Phillies over the past three years. And while most of the projections for 2012 don’t expect Mayberry’s success to continue, many fans would also say he’s earned a chance to prove that what he’s done so far at the major league level is not a fluke.

In 369 plate appearances with the Phillies, Mayberry has put up a surprising 265/328/518 line. In 2011, he got 296 plate appearances and slugged .513. Of the 141 NL players who got at least 275 plate appearances in 2011, Mayberry’s .513 slugging percentage was 15th-best. Of those same 141 players, his isolated power of .240 was tenth and the best on the Phillies. Ryan Howard’s isolated power of .235 was 13th-best among NL players with 275 plate appearances in 2011. Coming into 2011, Mayberry had hit six home runs in 73 plate appearances and had an absurd isolated power mark for his career of .304.

From 2005 to 2011, John Mayberry got 2,975 plate appearances at various levels in the minor leagues and posted a 258/328/457 line overall. About half of those plate appearances came at the Triple-A level for Mayberry — he spent most the 2008 season hitting in the extremely hitter-friendly PCL before seeing time in Lehigh Valley in 2009, 2010 and 2011.

Since the start of 2009, Mayberry has gotten 1,027 plate appearances at Lehigh Valley in which he has hit 263/325/431.

Here are Mayberry’s numbers from all levels in the minors, just at Lehigh Valley over the past three years and with the Phillies. Also included are the percentage of plate appearances in which he has walked, struck out, singled, doubled or homered for each:

PA AVG OBP SLG % BB % 1B % 2B % HR % SO
All minors 2975 258 328 457 8.2 13.4 5.3 3.8 21.8
Lehigh Valley ’09-’11 1027 263 325 431 7.6 15.1 5.2 3.1 22.2
Phillies ’09-’11 369 265 328 513 7.9 12.7 5.4 5.7 22.2

Mayberry hasn’t just matched his minor league numbers in the big leagues, he has exceed them. He hit for a better average than he did in the minors with the same on base percentage and a higher slugging mark.

Mayberry’s strikeouts and walks with the Phils are very similar to what they were in the minors. He has struck out at almost the same rate while walking more regularly than he did at Lehigh Valley, but less than his time in the minors overall.

He has been more likely to get a hit with the Phils than he was in the minors. He has gotten a hit of any kind in 24.1% of his plate appearances with the Phils. He got hits in a similar 23.7% of his plate appearances with Lehigh Valley and in 23.0% of his plate appearance in the minors combined.

What he hasn’t done is hit singles. His percentage of plate appearances that ended in a single are a lot lower than they have been at Lehigh Valley and lower than in the minors altogether.

He’s been a little more likely to double with the Phils than he was in the minors.

He’s been a whole lot more likely to hit a home run. 3.8% of his plate appearances in the minors overall, 3.1% in his plate appearances with Lehigh Valley and 5.7% of his plate appearances with the Phillies.

So far for his career, 47.2% of his hits at the major league level have gone for extra-bases. In the minors overall he saw 41.9% of his hits go for extra-bases. At Lehigh Valley is was 36.2%.

Important to remember is that while Mayberry showed monster power in limited chances in 2009, his other numbers were rather awful. Mayberry made his debut with the Phillies that year and on-based .250 in 60 plate appearances, going 12-for-57 with two walks and a hit by pitch. He ended the year at 211/250/474. In 2010 and 2011 combined, he’s posted a far better 276/343/527 line in 309 plate appearances.

Over the last two years with the Phils, he has walked in a higher percentage of his plate appearances (8.7%) than he did in either the minors overall (8.2%) or at Lehigh Valley (7.6%). He’s gotten a hit in 24.9% of his plate appearances with the Phils, also more than he did in the minors (23.0%) or at Lehigh Valley (23.7%). He has struck out less (19.1% with the Phils, 21.8% all minors, 22.2% at Lehigh Valley). The power numbers are where he’s up the most. With the Phillies he has registered an extra-base hit in 11.3% (9.6% all minors and 8.6% Lehigh Valley) of his plate appearances over the last two years and a home run in 5.5% (3.8% all minors and 3.1% Lehigh Valley).

So, will Mayberry’s numbers with the Phils continue to dwarf his minor league output? Let’s hope for the best. Either way, he should be getting a whole lot of chances in the early going in 2012.

This suggests we shouldn’t expect to see too much of Utley early in Spring Training. It also suggests that Contreras could be ready for Opening Day and that Justin De Fratus has some tightness in his right elbow.

The Phillies and Kyle Kendrick agreed to a two-year, $7.5 million contract.

Manuel calls Juan Pierre a top-of-the-order hitter in this article. In 2011, Pierre got 729 plate appearances with the White Sox in which he on-based .329.

The Phils will get a supplemental pick in the 2012 draft now that Ibanez has signed with the Yankees.

Here’s the Spring Training roster for the Phillies.
