Angels hope playing the numbers game adds up to something special

General Manager Tony Reagins says the team is using more of baseball's advanced statistics, like UZR and VORP, to help evaluate players and teams. Manager Mike Scioscia isn't totally sold on the all the new calculations.

Reporting from Tempe, Ariz. — To Mike Scioscia, UZR might as well be a demilitarized zone between warring countries and VORP a word Captain Kirk used when he wanted Scotty to beam him up to the Starship Enterprise.

To the statistics-savvy baseball follower, UZR stands for ultimate zone rating, an advanced metric that estimates a fielder's defensive contribution, and VORP is value over replacement player, the number of runs contributed beyond what a replacement-level player at the same position would contribute.

Scioscia, entering his 12th season as Angels manager, concedes that he is a bit of a dinosaur when it comes to baseball's more exotic stats, especially the ones measuring defense and forecasting player and team performance.

He has reason to be skeptical.

In its annual PECOTA (Player Empirical Comparison and Optimization Algorithm) projections, Baseball Prospectus has predicted 76 to 86 wins for the Angels in each of the last seven seasons. They have averaged 92 wins in that span.

"They've had us losing 90 games for the last [seven] years, and we managed to win 90 [five times]," Scioscia said. "I think it's a young science … I don't know."

Scioscia has doubts about the new-age stats, but the Angels front office is coming out of the Stone Age — or, more precisely, the Bill Stoneman Age — in its use of statistics to evaluate players and opponents.

"We definitely use them," said Tony Reagins, who replaced Stoneman as the Angels' general manager after the 2007 season. "It's like baking a cake. It's an ingredient, something you can use to evaluate your team and your opposition."

When teams such as the Oakland Athletics and Boston Red Sox began incorporating more "Moneyball" philosophies emphasizing plate discipline and on-base percentage in the early 2000s, the Angels lagged behind.

Instead of putting a premium on players who worked counts, drew walks and drove up opposing starters' pitch counts, the Angels seemed to favor such free-swingers as Vladimir Guerrero, Howie Kendrick and Erick Aybar.

It's hard to argue with their approach; the Angels won the 2002 World Series and reached the playoffs five of the last seven years.

But the perception that the Angels are too old-school for baseball's "sabermetric" age is changing.

"Moving from Stoney to Tony, my sense is they're using more of the statistical-based information," said David Forst, assistant GM of the Oakland Athletics, one of baseball's more stats-savvy clubs. "Tony seems more open to it in the GM chair than Bill was."

The Angels did not go so far as the Red Sox, who hired Bill James, famed baseball historian, statistician and the father of sabermetrics, as a senior advisor in 2002.

But four years ago they hired law-school graduate Justin Hollander as an assistant for player development and scouting, and his primary job is to evaluate and analyze statistics for Reagins and the coaching staff.

"We use it for base-running, offense, defense, everything out there, we use," said Hollander, 33. "If Tony asks me to look at a guy in terms of a long-term contract, trade, free-agent signing, minor leaguer, he will know what I'm thinking and assign a value to it."

The volume of statistics available with a few clicks of a mouse is mind-boggling and gives a comprehensive picture of players and teams, especially on offense.

The last five years has also seen a new wave of defensive stats, with websites such as and John Dewan's Fielding Bible, first published in 2006, quantifying things such as range, positioning, arm strength and error rate.

"We feel like we've put together a good defensive team the last few seasons, and there's no doubt those stats have been a factor in our decisions," Forst said of the A's, who had the fifth-best UZR in baseball last season.

"What you like is when the stats match up with what scouts see with their eyes. That's when the best decisions are made."

Stats such as UZR assign numerical values to defensive components in an attempt to determine how many runs a player saved or gave up as a fielder.

But Scioscia argues that the data or formulas are flawed because they don't consider advance scouting reports and spray charts that affect the positioning of players.

"I couldn't tell you if Derek Jeter is a plus player because I don't know where their spray charts tell him to play," Scioscia said. "We understand it when Aybar doesn't get to a slow roller up the middle because he was shaded so far toward third base. No shortstop would get to that ball, but if you're grading it, it's a minus."

Angels rookie Peter Bourjos rated third among American League center fielders with 15 runs saved last season, even though he played only two months in the big leagues, stats that support Scioscia's belief that Bourjos has Gold Glove potential.

But the manager remains skeptical.
